GeneralGail's NEW favourite of the day, PART 2

11th Nov 2011 12:07 GMTJolyon Ralph Founder

Continuing Gail's excellent thread.

Here were her rules, which I totally agree with:

"Hey everyone, on this thread let's stick to favorites that you have in your collection, or that you have seen in a Museum. NOT what you have for sale! The original concept of my Favourites thread is to chat about, and show, a piece that you really enjoy on that particular day. Limit ONE posting per day! It started for me when I was walking past a case in our home, stopped, turned on the lights and admired a piece in our collection that really gave me a thrill. Thus the name, Favourite of the Day. Don't worry about sizes unless you wish to add them, many new people aren't overly familiar with sizing their minerals and this is a FUN thread, sorry to the moderators who will cringe at that. This thread is about showing the mineral that THRILLS you today! "

11th Nov 2011 14:39 GMTPeter Andresen Expert

This specimen with silver and erythrite from Nippissing 404 Mine in Cobalt, arrived in the post today. From Maggie Wilson and Reiner Mielke - I would have kissed you both, or at least a very good hug ;) when I opened it, and could look at this 3,5 x 3,2cm treassure. This will be a favourite for many, many, many days, months and years!!! X(

Photo is by Maggie, I couldn't have done it better :)

11th Nov 2011 15:08 GMTMichael Shaw Expert

Calcite - Daye Mine, Edong District, Hubei Province, China. 6.1 x 8.7 cm

11th Nov 2011 16:02 GMTAdam Berluti

Nice calcite Michael. Here is a chalcedony from Tampa Bay.

11th Nov 2011 17:37 GMTGerhard Brandstetter Expert

Love that silver wires with Erythrite - a real beauty!

Today i'll show you the good ghost of Mindat:

Agate, 11 cm - Nowy Kosciol, Lower Silesia, Poland.

A look in his eyes makes me smile!

11th Nov 2011 19:19 GMTDon Windeler

Fabulous silver, Peter – I’m a copper guy myself, but would love something like that on my shelf! Michael, my first thought at seeing your calcite was somewhere in Indiana, as Midwestern US calcites are another favorite of mine.

Back in August I organized a group display case for the SF Crystal Gazers at the San Francisco Gem & Mineral Society’s annual show. The theme was “A Sea of Gems” and we went with the approach of a mineralogical coral reef.

With the 11/11/11 date, the entertainment section of this morning’s newspaper made reference to “Ocean’s 11” among other numerologic silliness, which reminded me of the case.

Not a single mineral, admittedly, but it’s one of my favorite pics. Cheers!

Green Street,

Go to the top of this page and press new topic. Call it "No Gangue" in the subject box and fill in the large message box with what you want said.


11th Nov 2011 23:48 GMTMalcolm Southwood Expert

Green Street,

Why not register first with your real name? Otherwise we might think you are someone else in disguise, if you get my meaning:)

Just a thought!


12th Nov 2011 00:24 GMTAndrew Tuma Expert

Peter that is seriously nice Silver...just a stunning combination.

Getting over some recent negativity I though I better do what this thread is for and post a few special bits share so others can enjoy. So here is the first.

And I agree with Peter that some minerals are just favorites for more than one day. The following specimen is one of these for me...(and it is not mine), self collected by my son Luke at Mt Bischoff a couple of years ago. Amazing 8mm +/- ball of vivianite on fluorite, and yes this is the right colour.

Now how to get it into my collection...;)



12th Nov 2011 02:45 GMTGail Spann Manager

This arrived today, we had bought it and then saw Jolyon had put it in his Munich show report. Jim is ecstatic, it's a fine adventure under the microscope I can tell you!

Here is our new Genthelvite with Quartz on Andradite. China

Jolyon took the photo, I borrowed it with his permission.

12th Nov 2011 03:06 GMTRob Woodside Manager

That's a nice Genthelvite. Where is it from?

12th Nov 2011 04:41 GMTJohn M Stolz Expert


I'm still picking myself off the floor after your silver/erythrite. I am absolutely taken by it! Congratulations!


12th Nov 2011 06:42 GMTRay Hill Expert

I really really want to know where Maggie and Reiner got that piece...was it a purchase from an old collection? self collection? and if so , How long ago? And if they collected it , do you have another similar piece I might be able to obtain?

It is "the piece" I have been looking for from Cobalt ever since I got my first group of Cobalt silvers....and they are the nicest erythrites that I have ever seen from there, and to have that all combined

so beautifully, with such a killer Silver wire group....OOOOh , I so want that in my collection....

but I fav for today, resides in my Mount Brussilof collection and is the nicest

and gemmiest < and it is a DT> natrolite xl that I have ever seen out of Mount Brussilof. < with dimensions of 5.45 x 3.49 cm> please enjoy

12th Nov 2011 08:36 GMTPatrick Gundersen

Here's one that jumped out of the cabinet and begged to be photographed, an unusual "heart" shaped, double terminated Amethyst "reverse-scepter" Quartz crystal from Harts Range, Northern Territory, Australia, measuring 40mm x 40mm, collected in 2009.

12th Nov 2011 09:33 GMTValere Berlage

Here is what I want to share today! This year is a nice year for Morocco, and some nice erythrite went out from two mines, including this one, from Bou Azzer, It has the style of the finds of the 50's: large crystals, quite tick, with very sharp terminaisons.

So many crystals, up to 2 cm long, on a 12 cm speciment. A little souvenir from Munich. Even during my 3 trips to Bou Azzer, I never saw an erythrite looking like this!

Have a great day to all


12th Nov 2011 13:24 GMTGail Spann Manager

My favorite of the day is this grouping of minerals in our U.K. case. I found myself standing there this morning, just loving all these minerals.

The Witherite, in particular, catches my attention.

12th Nov 2011 15:45 GMTMichael Shaw Expert

This inesite from the NcChwanning II Mine is today's favorite. 7.2 x 9.5 cm.

12th Nov 2011 18:13 GMTTony H. Gill Expert

This just has to be one of my all time favs! Topaz on Quartz from El Chaltén, Argentina!

12th Nov 2011 20:17 GMTJuergen Merz

Today I cleaned my collection. Always a pleasure for me is to see this Crocoite miniature from the Adelaide Mine.

4.0 x 4.0 x 2.5 cm.

13th Nov 2011 06:40 GMTStephanie Martin

Awesome photos everyone!

Peter! :)-D I do not know how Reiner and Maggie were able to let that one go, but I'm sure that what made it easier is knowing that you will take good care of it. That is a truly exceptional, galaxy class specimen ~ berry extraordinary !!!

There are currently many Best Of threads running and while they are inspiring it is difficult to keep up with them all (:D

And now for a wee bit of fun.

I get a giggle out of these and in this case I think 3 are more fun than just one.

Sand Calcite concretions

Borsod-Abaúj-Zemplén Co., Hungary (near Malyi)

longest one rear right - approx 6.0cm x 3.5cm

13th Nov 2011 08:55 GMTAM Mizunaka Expert

Transparent fluorite cubes with calcite from Dal'negorsk is today's favorite. 6.9 x 5.0 cm.

13th Nov 2011 13:02 GMTMaggie Wilson Expert

AM! spectacular photo! ::o

13th Nov 2011 14:25 GMTRalph Bottrill Manager

My latest acquisition:

13th Nov 2011 17:18 GMTDebbie Woolf Manager

Very nice specimens everyone, it's a pleasure to view them.


14th Nov 2011 03:41 GMTGail Spann Manager

This is the first mineral that Jim and I purchased together in Breckenridge , Colorado, at a small shop called Nature's Own. I thought it might look nice on our coffee table, ha!

When we left the shop I turned to Jim and said " I can't believe how much we just paid for a ROCK!"

They also gave us a copy of the MinRec Sweet Home mine publication and a DVD of the SHM history.

This is what got us to the Houston Museum to go see the Alma Queen. I fell in love with minerals while there and that was the start of that!

So, to our first piece purchased as a couple......

14th Nov 2011 16:04 GMTJoseph Polityka Expert


Gail, I see a lot of miniatures in that beautiful rhodo.

Maybe this specimen in our collection came from the same pocket?

Rhodocrosite. Cash Flow Pocket 1992. 4 cm by 5 cm.

Joseph and Lorraine Polityka collection. Pictured in "The Mineralogical Record", Vol. 29, #4, 1998. A photo of this specimen is on page 27

Best wishes,


14th Nov 2011 16:17 GMTMichael Shaw Expert

Gail, it's nice to be able to look back on the one specimen that got everything started. I wonder how many collectors still have that first piece that sent them down this crazy road. For me it was the following piece that I was given back in 1963 by a generous collector friend.

Calcite - Put-In-Bay Island, Ohio

15th Nov 2011 09:14 GMTAM Mizunaka Expert

Today's favorite is a pale blue apatite cluster on quartz from Portugal. 2.6 x 4.7 cm.

15th Nov 2011 16:30 GMTGail Spann Manager

Everyone's photos are spectacular, great to see.

AM, wow.....speechless.

15th Nov 2011 21:24 GMTJoseph Polityka Expert


Great specimens and great photos.

I'm still in a hungry mode and mood: Apatite on quartz, 7.5 cm by 7.5 cm from the Noyes Mountain Quarry (Harvard Quarry), Greenwood, Oxford County, Maine.



16th Nov 2011 01:18 GMTGlenn Rhein

My favorite of the day was this 3cm spinel on chondrodite which I call " A spinel cone", until I saw AM's blue apatite on quartz.

16th Nov 2011 09:40 GMTRay Hill Expert

This miniature pyrites from Nanisivik mine, now closed for over 10 years, is a nice example of the less common simpler crystal forms . Usually the pyrites and pseudomorph marcasites from this mine are much more complex. It is one of the pieces in the Babet Collection that I have.

18th Nov 2011 14:36 GMTAdam Berluti

Here is a calcite crystal from Indiana

19th Nov 2011 00:00 GMTJoseph Polityka Expert


Nice Indiana calcite.

I went into New York last week for lunch and visited the American Museum of Natural History with my daughter. I happen to like Mimetite so I thought I would post a picture of this classic which is in their collection. Huge crystals of Campylite from Roughten Gill, Cumbria, England.

The speicmen is approximately 10cm by 16cm in size.



20th Nov 2011 13:13 GMTGail Spann Manager

The one that got my attention today, this lovely Brookite.

20th Nov 2011 14:36 GMTIbrahim Jameel Expert


Are you sure the locality on that brookite is correct? It looks more like one of the pieces from Baluchistan Prov. (most likely Kharran, where the majority if these things came from). Zagi Mtn is farther north near Peshawar and the border with Afghanistan, and I haven't really seen any decent brookite from there...


20th Nov 2011 17:29 GMTGail Spann Manager

One never really knows, it is what was stated when we bought it from the Arkenstone. We have it labeled as such but we will research it now that you have brought it up, we have had this piece for quite some time, so need to ask our friend who often goes to Pakistan. I don't doubt your statement though, not unusual to find out things are not from where they were stated to be from.

Thank you.

20th Nov 2011 17:30 GMTGail Spann Manager

Ibrahim, do you think it is from the Dalbandin area? All our other Brookites are from there.

We have nine other Brookites from the area you suggest. We will change the info on the above piece, again..thank you!

Here is a recent one, very different, from the Obodda private collection, now in our collection.

20th Nov 2011 17:52 GMTIbrahim Jameel Expert


I really couldn't tell you precisely.... Mindat lists 7 occurrences of brookite in Baluchistan Prov.: Taftan, Dalbadin, Quetta, and 4 localities in Kharran (including Kharran itself).

The listing for Quetta is almost certainly an error.

Unless your source obtained this piece at the mine, it would be impossible to determine the locality with certainty. In all likelihood, your brookite was found somewhere in Baluchistan then taken to Peshawar, where it probably changed hands a couple times. It was exported from there, and may have changed hands a couple more times in the western market (assuming you did not buy it from a Pakistani dealer.)

In any case, the original locality information of this piece and your other brookites was probably lost as soon as the specimens made it to Peshawar. Baluchistan is the only part that is certain, beyond that probability would point to somewhere in Kharran.


20th Nov 2011 17:55 GMTGail Spann Manager

Thank you again! Appreciate your help.

21st Nov 2011 05:32 GMTAM Mizunaka Expert

Fluorite with quartz and calcite from Naica is today's favorite. 6.9 x 5.3 cm.

21st Nov 2011 14:38 GMTIkram Mohammad Expert


i would like to add more precisely for your brookite is Thurdok(Thurdook) , Zard , Kharan District , Baluchistan , Pakistan.



21st Nov 2011 23:55 GMTGail Spann Manager

Thank you Ikram.

23rd Nov 2011 03:25 GMTBarry Miller

This is only one half inch. But this clear smoky quartz that I found 43 years ago in Rosendale, New York, is my favorite for today.

23rd Nov 2011 16:47 GMTMichael Shaw Expert

While photographing this specimen this morning I realized how much I like the combination of rose quartz, feldspar, and muscovite. Pitorra Mine, Lananjeiras, Brazil. 6.0 x 6.8 cm.

24th Nov 2011 07:50 GMTPhilip Perkins

My favourite that catches my eye everytime that i walk past it, due to it's beautiful color,

is this Saleeite, from the Ranger Mine, NT, i believe it was found in the early 80's.

crystals average 6mm...

25th Nov 2011 06:20 GMTAM Mizunaka Expert

A pale green fluorite cube from Alaska is today's favorite. 2.4 x 2.5 cm.

27th Nov 2011 08:49 GMTAM Mizunaka Expert

Continuing the fluorite theme. Blue fluorite on quartz with chalcopyrite.

28th Nov 2011 20:51 GMTBob Griffis Expert

My favorite today is...

Smithsontite on Coronadite

MMM Open Cut

Broken Hill

New South Wales


65.0 x 47.0 x 30.0 mm overall. Lustrous, translucent, frosted, light-grey, tear-drop-shaped Smithsonite to 3 mm richly covers a grey to sparkling black matrix of Coronadite.

29th Nov 2011 00:53 GMTLuiz Alberto Dias Menezes, Fo.


Very nice rose quartz; the correct name of the locality is Pitorra mine, Galiléia, Minas Gerais.

29th Nov 2011 02:11 GMTPhilip Perkins

This one is always my favourite Topaz, Marambaia Mine, MG. Brazil.

love it for it's termination, the crystal is 12.5cm high, maybe Luiz can tell me if the locality is correct?

29th Nov 2011 02:27 GMTRuggy Holloway

Very nice specimens all

My favorite this past week - Stibnite with Gold, Baia Sprie, Mamures, Romania- 4x3.5x2 cm roughly

note scale in lower left of photo

29th Nov 2011 10:43 GMTAM Mizunaka Expert

Today's favorite is anatase inclusions in quartz from Russia.

29th Nov 2011 14:50 GMTJoseph Polityka Expert


Thanks, everyone, for sharing photos of your beautiful specimens.

My favorite today is bixbyite, 2cm crystal, from the Thomas Range, Juab County, Utah. Formerly in the Minette collection.

Best wishes,


1st Dec 2011 16:39 GMTBob Griffis Expert

Today's favorite...I have had this for over 30 years, and rediscovered it.

75.0 x 60.0 x 37.0 mm overall. White blades of Barite form interlocking groups of distinct appearance, with blades reaching 2.2 cm on edge. Choice small cabinet from this classic American mine.

2nd Dec 2011 15:55 GMTBob Griffis Expert

Today's contribution....

148.0 x 80.0 x 40.0 mm overall. Striking specimen of opaque cream-colored rhombs of Dolomite to 2.1 cm nicely perched on limonitic matrix. The Calcite crystals partly engulf glassy Hemimorphite crystals to 1 cm in length. Translucent yellowish Mimetite in spherical crystal aggregates to 3 mm are perched on both Hemimorphite and Calcite crystals.

2nd Dec 2011 16:15 GMTJay Buscio

AM, Love your floating Anatase crystals!!

Bob, It would be nice to know where the specimens in your last two posts are from.

2nd Dec 2011 16:21 GMTBob Griffis Expert


The Dolomite is from San Antonio Mine (San Antonio el Grande Mine), East Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico.

The Barite is from Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA.

2nd Dec 2011 16:23 GMTMaggie Wilson Expert

Hi Jay - clikck on the photo and it will take you to Bob's gallery page - in the latest post, that GORGEOUS dolomite piece is from here , San Anotino, Mine

A beauty, Bob!

the Baryte is from Bisbee

2nd Dec 2011 16:32 GMTJay Buscio

Bob, Maggie thanks. That's one fine dolomite and hemimorphite you got Bob. Looks very similar to a piece I have from the same locale collected back in the 1960's.

2nd Dec 2011 16:44 GMTBob Griffis Expert


The 1960s is about the correct time frame for this piece as well.


2nd Dec 2011 18:32 GMTJoseph Polityka Expert


This is just a quartz crystal from Brazil 2.5cm by 6cm. What makes it unusual is its 2mm thickness. It possibly formed in a book of mica.



4th Dec 2011 16:41 GMTBob Griffis Expert

Today's favorite is .....

Mercury with Cinnabar

Socrates Mine

Pine Flat District

Sonoma County, California

United States of America

72.0 x 52.0 x 41.0 mm overall. An extremely rich specimen liberally covered with shiny silvery globules or drops of native Mercury (quicksilver) on a Cinnabar-rich matrix. Mercury is the only recognized mineral that is found as a liquid at room temperature. Cinnabar alters to native mercury in the oxidized zone of deposits. Native mercury is also quite rare. This specimen is from an uncommon California locality, the Socrates Mine. Very rare in specimen form and a very difficult element to obtain in its pure form for an elements suite in a collection.

4th Dec 2011 21:55 GMTJay Buscio

Fluorite, on St. Genevieve Limstone, Rosiclare Horizon, South End, Denton Mine, Illinois. Mined in January 1983. Measures 5.5 x 4.5 x 2.2 cm.

5th Dec 2011 01:58 GMTLuiz Alberto Dias Menezes, Fo.


Nice and sharp topaz; the locality looks correct, but Marambaia is indeed the name of a district, where there are many small mines (most unnamed), and you can also add the name of the city: Caraí; so I would write it as "Marambaia district, Caraí, MG, Brazil".

5th Dec 2011 08:36 GMTAM Mizunaka Expert

A floater cluster of pyrite from Austria is today's favorite. 4.9 x 4.7 cm.

5th Dec 2011 15:58 GMTMichael Shaw Expert

Cerussite - Tsumeb, Namibia 3.6 x 5.3 cm

7th Dec 2011 16:47 GMTBob Griffis Expert

Silver, Calcite

New Nevada Mine, Batopilas, Andres del Rio District, Mun. de Batopilas, Chihuahua, Mexico

36 x 25 x 15 mm overall. This native Silver from Batopilas is a classic example of the herringbone-style this locality is famous for. It has sharply elongated spinel twins, connected together in an aesthetic framework. What sets this specimen apart from most is the accents of snow-white Calcite, some showing classic rhombs.

9th Dec 2011 05:09 GMTStephanie Martin

Even though I haven't been able to post much lately, I have been enjoying everyone's specimens. Thank you for all for sharing!

My postman brought me a number of nice items this week, and while I have been trying to work on my Canadian section, I made time to snap a few pics of some that were better in hand than expected. I love it when that happens!

My favourite for today is this nicely centered almandine in schist from the Alps.


Ötz valley, North Tyrol, Tyrol, Austria

specimen approx 6cm x 4cm

Crystal approx 12mm x 12mm

9th Dec 2011 08:22 GMTAM Mizunaka Expert

Pyrite from the Czech Republic. 4.5 x 3.3 cm.

9th Dec 2011 22:32 GMTPeter Andresen Expert

A smal spesimen I've played with in front of the camera today, just because it's caught my eyes...

10th Dec 2011 02:45 GMTJoseph Polityka Expert


Thanks for posting those great specimens from classic and unusual locations.

My favorite for today is Pyromorphite on quartz, 6cm by 10cm. from the classic Bad Ems location in Germany. Formerly in the late Neal Wintringham collection. Neal aquired the specimen in the 1950s from the Sunshine Acres School in Mays Landing, New Jersey. Sunshine Acres was a nudist colony in southern New Jersy that was run by a clergyman, so I was told.

Best wishes,


10th Dec 2011 06:46 GMTStephanie Martin

Joseph, I am amazed at your historical pieces, with very interesting stories!

Yet another iron mineral as my favourite today, and from another classic locale.

Just a thumbnail, however it has a colourful personality along with some iron stained quartz teeth.

The iridesence is evident an all sides of the piece.

Hematite, Quartz

Rio Marina, Elba Island, Livorno Province, Tuscany, Italy

Approx 2.0 x 2.0 cm

10th Dec 2011 10:37 GMTDavid Sheumack

A great example Stephanie, of the colours that iron and manganese can impart . My example is by no means a classic sample nor from a classic site but has always caught my eye. The photo FOV is about 4cm, of a sandstone cobble from Maroota, NSW, Australia. I live in sanstone country surrounding Sydney where one of a few volcanic dykes intrude the wet sandstone formation. A friend mines sandstone in the area and many years back excavated into the said sandstone adjacent to the dyke. The fresh excavated material in 5 tonne boulders was to say at the very least, eye catching in the sunlight, BIG BLUE/PURPLE irridescent boulders. Alas all I was allowed to grab were a few hand sized pieces. The memory lingers on :-)

11th Dec 2011 06:35 GMTStephanie Martin

David, thanks for sharing the memory of your lasting impression, at least you were able to get a few pieces to preserve the moment. Who could resist the lure of those colours?

For today… these andradites that instantly charmed me by their form and placement.


Imilchil, High Atlas Mts, Er Rachidia Province, Meknès-Tafilalet Region, Morocco

Specimen overall size approx 4cm x 2.5cm

Largest crystal approx 1cm x 1cm

11th Dec 2011 09:12 GMTAndrew Tuma Expert

A favorite for today,

I always wanted a matrix specimen of an Emerald from Torrington NSW, and last Zeehan show i finally found one. 60mm high/


13th Dec 2011 14:43 GMTGail Spann Manager

Amazing minerals everyone!!!!!!

13th Dec 2011 15:31 GMTBob Harman

BOB GRIFFIS, in your description of cinnabar and liquid mercury globules given with your specimen above on this page, your statement "mercury is the only mineral that is liquid at room temperature" is not quite correct as most scientists consider WATER H2O a mineral (ice) and, of course, it is a liquid at room temperature.

14th Dec 2011 09:35 GMTDavid Sheumack

What great photos of pieces that catch our eye have been produced this year. This particular piece I have been trying to photograph for some time with rather poor success but at last the something is starting to please me, but it still has a long way to go. Ahh the holidays!!!

Over the past 12 months, may helpful tips and tricks for that "better mineral photo" have been provided by mindat professional photographers, recently "Better Backgrounds....." by Volker B has been especially helpful for an amateur like myself.

A very informative 2011 from Mindat it has been,

Thank you Mindat and a Very Merry Christmas to you all (tu)


15th Dec 2011 03:40 GMTDavid Sheumack

Woops, I forgot the identification of the previous specimen: hematite roses with etched quartz. From Jinlong, Quangdong Prov.

15th Dec 2011 05:18 GMTStephanie Martin

Andrew, congrats on obtaining an elusive specimen. It is a mighty fine one at that.

David, nice rosettes! I agree there has been a lot of help in regards to photography...still working at getting better and being consistent and for this you are all kind to put up with my posts.

Although the cubes are incomplete on this specimen they still make for an interesting formation, so it is my favourite today.

Calcite on Chalcedony (stalactite)

Nasik District, Maharashtra, India

overall approx 8cm x 5cm

pillar approx 3cm

larger cube approx 12mm x12mm (incomplete)

15th Dec 2011 06:37 GMTJohn M Stolz Expert

Always a pleasure to browse the posts. You guys have such interesting specimens!

15th Dec 2011 09:05 GMTAM Mizunaka Expert

Today's favorite is a cluster of fluorite with pyrite and muscovite from Kazakhstan. 5.1 x 3.5 cm.

15th Dec 2011 09:35 GMTTomasz Praszkier Manager


your calcite is very nice. But id doesn't looks like pseudostalactite. It's looks more like first generation calcite covered by quartz with syntaxial calcite of second generation. Very nice.


15th Dec 2011 13:52 GMTStephanie Martin

Hi Tomek, thank you for your observations, I will take away the reference as stalactite.

stephanie :-):-)

15th Dec 2011 18:53 GMTJohn M Stolz Expert


I can't get my arms around this piece. I don't understand the reference to the stalactite--what I'm seeing is host rock that over which id deposited some unknown material that forms the base for the fluorites and which is then dissolved and replaced by the micro quartz. I see no way for the fluorites to form otherwise...


15th Dec 2011 19:31 GMTStephanie Martin

John- I was refering to the 'pillar' as a stalactite. No fluorites on this piece, only chalcedony (over basalt) and calcites. The chalcedony covering the basalt is blue tinted and the pillar is white, adding to the confusion.

steph :-)

15th Dec 2011 19:56 GMTSteve Sorrell Expert

Haven't had the opportunity to look at or post to this thread for a while. Some very nice specimens. Thanks for sharing.

Here's my latest contribution - chalcophyllite from Majuba Hill. Chalcophyllite is one of my favourite mineral species. Something to do with the colour and form...



15th Dec 2011 20:29 GMTTomasz Praszkier Manager

John, as you can see even on photos quartz is covering light yellow calcite. This is very typical for Maharastra specimens.


16th Dec 2011 03:28 GMTJohn M Stolz Expert

LOL, my bad--substitute calcite for fluorite. The rhombs look like cubes. But I still don't understand -- are you saying there's another calcite sandwiched between the two--and totally covered by chalcedony? How else would you otherwise get 2nd generation growth occuring between 1st generation crystals?


16th Dec 2011 04:18 GMTStephanie Martin

John - yes that's what Tom is saying. If you look more carefully in the close up in the foreground there are some light yellowish crystals which are calcite, hard to notice them under the white quartz druse but they are there, and then the pillar form with more white quartz and the darker generation calcite cubes.

Today my favourite is this smoky quartz scepter. Precise locality not available.

Smoky Quartz

Namaqualand, Northern Cape Province, South Africa

approx 4cm x 2.5cm

17th Dec 2011 10:40 GMTSteve Sorrell Expert

There are quite a few images of acicular or filiform pyrite from the Clackamas River localities on Mindat, but none that look like this one. This specimen doesn't have a specific locality, just Clackamas River, and was acquired by Joan Lamond (Melbourne) from Sid Sparkes in Vancouver in 1985. The original pyrite, now altered to goethite, has taken a couple of right angle turns, and produced a pair of octahedral pyrite crystals. An interesting specimen! Picture width is 4mm.



17th Dec 2011 14:44 GMTTimothy Greenland

Steve, I'm a chalcophyllite fan too - especially when it is self collected! I have therefore elected this piece as my favourite of today... I'm not really cheating with the second 'photo - I hope. It is on the same specimen - a little cyanotrichite tangle. The largest chalocphyllite crystals are about 1 mm across; as is the cyanotrichite bunch. The specimen is from Cap Garonne, Le Pradet, Var, France and was collected on the 28 August 1964. Memories, memories!



18th Dec 2011 00:02 GMTGail Spann Manager

This whole favorites thread never ceases to amaze me! Anyhow, here's a calcite I got from Blake Barnett, or Austin Texas, after practically holding him down and twisting his arm to let me buy this from his collection! ha ha.

Calcite, China. No details as I haven't catalogued it yet, but it's about 3 inches tall.

18th Dec 2011 03:37 GMTJohn M Stolz Expert

Here's a nice little piece that just came in the mail...

The snowy quartzite make a nice background, no?

My wife thinks it would make a nice pendant.

The situation is tense.

Just spent the weekend going through our thumbnail collection and Thought I'd share this specimen here that was collected by John Lindell of Seattle Washington back in 1982.

21st Dec 2011 01:15 GMTMaggie Wilson Expert

Found this little thumbnail crystal at the London show this past November. We figured we'd never find stibnite crystals from China that would fit in a perky - assumed that only the larger and showier material was given any consideration, but we were wrong! What I really like about this little piece is that it has a growth irregularity - from the first angle, it looks nice and straight, but you can see that there is a slight "kink" in the crystal growth. I can hear my grade school teacher admonishing me to "stand up straight, young lady, don't be a slouch!"

23rd Dec 2011 07:03 GMTGail Spann Manager

24th Dec 2011 07:36 GMTSteve Sorrell Expert

I posted this one in the Arizona thread but decided to post here as well for a bit of fun. Two photos (sorry Gail) but it's the same image!

Sometimes it pays to have imagination and a sense of humour. According to my wife, I have neither!

This specimen has a couple of azurite crystals sitting atop a malachite sphere, with tiny minor cuprite.

However, I also see Snoopy from Peanuts sitting there, probably having been downed by the Red Baron! Can you see him? If you can't, have a look at the second photo...

I have posted several other Indiana geodes containing BARITE in the self-collected thread, but, this is not a self collected example in my collection. It was found about 30 years ago in a stream bed ravine in southern Monroe County, Indiana. This stout, well terminated and color zoned lustrous blade measures 5.5 cm wide x 4.5 cm high x 0.9 cm maximal thickness. The geode half measures about 15 cm x 10 cm. I think the specimen had passed thru several hands prior to being acquired by me from another prominent Indiana geode field collector about 10 years ago. While there is some indication that it may be expertly repaired at its base, it is still a great example of an Indiana barite. As I have mentioned elsewhere, Indiana geode barites are probably the best of all in the Midwest; someone out there have a non Indiana example of a killer barite in a midwest geode??

26th Dec 2011 20:31 GMTPaul Siegel

This arrived a week ago, just in time for Christmas. Amethyst and Pyrite from the Turt Mine, Satu Mare, Romania.

Fluorite perched on the lip of a celestine bowl from Cave-In-Rock, Illinois. 4.9 x 4.6 cm.

5th Jan 2012 15:41 GMTBob Griffis Expert

This is one of the few rocks I regret having to sell, but had to pay for the collecting trips....I ran across a snap shot I took in about 1995, scanned it and loaded it on Mindat the other day. This is one of my favorites and the best rock I have personally collected (and spent over 80 hours prepping...exposing each garnet buried in the hard matrix using air scribes.) This was also the best of these found.


Sierra de Cruces, Mun. de Sierra Mojada, Coahuila, Mexico

The specimen is approximately 20 cm across, and the largest Grossular crystal is about 7 cm long. The matrix is a mixture of fine grained clear to whitish garnets and what is likely wollastonite. This specimen was collected by Graham Sutton and Bob Griffis in December 1993 from an isolated hill (Cerro de Moka) at the south end of the Sierra de Cruces mountain range. The garnet-bearing outcrop was at the top of the hill and was completely removed over 2 field trips. The specimen was sold to Dennis Beals and then was purchased by the Freiburg Museum, in the Pohl collection. Photo is a scan of a pre-digital print, so excuse the quality, and note that it represents the specimen prior to Dennis performing additional preparation work.

An old classic from the Adelaide Mine...



6th Jan 2012 17:53 GMTBob Griffis Expert


Old Yuma Mine, Saguaro National Monument, Amole District, Tucson Mts, Pima Co., Arizona, USA

40 x 35 x 8 mm overall. Lustrous, large, single fiery-orange Wulfenite crystal measuring 40 x 35 x 8 mm. This is a floater crystal with no point of attachment. This is an ex Arizona-Sonora Desert Museum collection piece I acquired in trade in 1992. No damage.


6th Jan 2012 19:20 GMTStephen Rose Expert

This specimen may not be particularly exciting, except for the memories associated with it.

During an exploration project that included the upper Cement Creek basin (just north of Italian Mountain) in Gunnison County, Colorado, we discovered float from this vein exposed in the shales in the creek near the head of the drainage. If the jeep trail is still open it is a great day trip. Especially if you have the energy to climb to the top of the ridge a few hundred yards north of the pyrite location, past the ruins of the old car and the miners shack, where you will have a wonderful view to the north of the mountains between there and Aspen.

Pyrite in etched calcite. Cubic crystals are modified by several forms including the pyritohedron, octahedron and diploid. 7x6x3.5 cm. Circa 1976.



8th Jan 2012 11:10 GMTSteve Sorrell Expert

8th Jan 2012 13:48 GMTBob Harman

This large 19 cm x 15 cm Indiana geode was found in 2004 on the Southwest Harrodsburg road cut in southern Monroe County by a long time Indiana geode collector. The calcites measure about 5.7 x 3.3 cm and 7.0 x 3.5 cm. The adjacent barite grouping measures about 3 cm with the largest individual xtal measuring about 1.3 cm.

10th Jan 2012 01:36 GMTGlenn Rhein

Really nice Steve..

After about fifty pictures I finally got a some good shots of this fluorescent Norbergite and Diopside. 2-1/4 inch Norbergite flower, six inches overall.


11th Jan 2012 20:01 GMTStephen Rose Expert

I have always liked the matte finish on this pyrite from Butte, Montana. The crystals are combinations of first and second order octahedrons, cube, pyritohedron and maybe the diploid. 7x3x4.5 cm.

This is my favorite of the day. I newly acquired Fluorite from Riemvasmaak. I really love the color of this piece and think it goes well with the photo of the terrain. I could not find a picture of the Mine, so I used this instead. Just a little project I've been working on this past week, making photo collages of my collection with photos of the locations.

12th Jan 2012 02:21 GMTPaul Brandes Manager

To go along with Gail's San Francisco Mine wulfenite; this is one I picked up through a deaccession sale at a museum several years ago. It measures about 14 cm tall!!

Paul, that's a beauty! And thanks, Conrad, just got it last night and love it.

12th Jan 2012 05:22 GMTStephanie Martin

Beautiful and interesting specimens one and all! Thank you for posting.

Gail, that is a stunning classic. Congrats!

Paul that is a huge piece! Very commanding.

Keeping with wulfenite, this specimen caught my interest due to the classic location and the contrasting colours which give it a rather wild flavour. The black druse would seem to be a manganese oxide but the back of the specimen shows some curious black blebs. This was collected by the Spirifer team in 2010 and not many specimens survived the dig due to the extremely friable matrix, so I feel lucky to have obtained this one.

I really like this one! Sellaite is a rare mineral, particularly as good crystallised examples, and twinning is not that common. This specimen exhibits twinning typical of other tetragonal species. And it's from my favourite collecting site!



15th Jan 2012 10:28 GMTPaul De Bondt Manager

Hi all,

Very nice favorites as usual, thank for shearing.

Stephanie, your unknown manganese mineral could be a zinc mineral, schalenblende.

It seems that the glubules are build up by different layers of the mineral. To my knowledge, manganse minerals are just sooty black all the way thru and not banded like yours. Check with this photo. Schalenblende come in a variety of shades going from light beige to dark brown. My specimen is from the lighter variety du to less iron content.

Let your piece checked and you will be surprised. Guarantee !

Schalenblende is much rarer than oridinary manganes oxides.:-)

I hope this helps.

Take care and best regards.


15th Jan 2012 14:22 GMTStephanie Martin

Paul, thank you for your observations! Yes the banding around some of the black blebs on the Mezica wulfenite piece made me also suspect it could be more than just the manganese oxides and the beginnings of schalenblende was my first thought as well. Very interesting that you suggested it.

Very nice specimen Paul, always find your photos to be fabulous. Thank you too, for sharing.

Most everyone has heard of the abundant collectible celestine from the Northwest Ohio and Southeast Michigan quarries like Clay Center and Holloway, Michigan, but collectible celestine also occurs in Indiana geodes. These 3 examples are related and my favorites, not only of this day, but in my geode collection as a whole. There are 2 quarries where they are found. Example 1 is from Lehigh Portland Cement Quarry in Lawrence County, Indiana. This is the old deep quarry, now extinct and filled with water; the current quarry is shallow with only a few poor quality colorless specimens. Examples 2 and 3 are from Salem Quarry in Washington County. This quarry still occasionally produces good specimens, but the best ones came out in the 1960s thru 1980s. An article on this quarry and it's celestine appeared in MinRec about 1981 or 1983 (?). Specimen 1 8 cm x 4.5 cm with the xtal 2.5 cm x 1.5 cm. Specimen 2 8 cm x 5.2 cm with the xtal 3 cm x 2.3 cm. Specimen 3 8.5 cm x 5.2 cm with the xtals about 3.5 cm x 1.8 cm.

15th Jan 2012 19:52 GMTStephen Rose Expert


Love seeing the Indiana celestites! Especially the Lehigh Portland Cememt Company quarry specimens.

My only collecting there was in the summer of 1966 shortly after the quarry had been closed and flooding was essentially at the level of the most productive geode/celestite zone. We had this information from some source, I don't remember who, and decided to organize a trip. There were three of us, maybe four, I can't remember if Dave Hess was along, including Lloyd Tate, Mel Dyke and myself. We parked on the gravel road north of the quarry and climbed up the the edge of the pit on the east side where there was a slope of spoil that we could clamber down into the north end of the main pit. The south end of the quarry had been mined to a lower level, but the north end, over an area of perhaps two acres, had been mined down to the top of the best geode zone. It was probably a natural, shaley break in the quality of the limestone and a logical place for the floor of a bench. The rocks there have a very shallow dip and while the south end of the pit was deeply flooded the north end was dry and the rock surface sloped gently into the advancing water.

We spent a hot 4-5 hours digging geodes and had about as many as we could carry when we finished. Many were taken whole to be opened later as a very high percentage of these contained celestite. My favorite memory of the trip is of reaching to arms length into a blast-generated crack that was entirely below water and feeling for open geodes on the rock surfaces. In one large geode opening I found three large, perfect floater crystals, one of which had a sharp marcasite phantom. When we reached the top of the rubble slope on the way out of the quarry there was a local farmer waiting for us, clearly curious about some nutty Bloomington guys working so hard on a hot day.

A couple of days later we all met a Mel's to open geodes and divide up the spoils. I think we destroyed his carpet, and, as I recall, Lloyd had collected something that the rest of us had avoided, a marvelous sunburn!

A great time was had by all.

Attached are pictures of the last of the three large, floater crystals mentioned above that I still have. 6x3.5x4 cm. Minor sugary quartz and yellow calcite attached.

Front view; shows hint of marcasite phantom.

Back view.

And another geode with a clear, 3 cm crystal in typical sugary quartz and yellow calcite geode matrix. Overall 9X5x4 cm.

Amethyst with "skunk" calcites is today's favorite from Brazil. 14.4 x 9.4 cm.

16th Jan 2012 20:09 GMTStephen Rose Expert

Love that name, "skunk calcites."

Bob Harmon's postings of Indiana geodes have spurred me to look through some boxes of old specimens. This one is from the Harrodsburg area in Monroe County, Indiana, and was collected from the excavations related to the construction of the spillway for the Monroe County Lake system in 1966. The geode contains quartz, pyrite cubes, a barite crystal and a dark mass of bright, cellular pyrite that may be pseudomorph after ankerite. The face of the larger part of the specimen measures 4.5x3 cm.



16th Jan 2012 20:28 GMTPaul De Bondt Manager

Hi stephanie.

Thank you for the reply. Always glad to help mineral friends.

What I didn't tell is that the schalenblende is much harder too than the manganese oxides. Manganes oxide also gives a black streak and schalenblende is very ligt beige.

I am happy you like my postings.

Take care and best regards.

A recent addition to our collection, nice miniature from Pakistan.

17th Jan 2012 14:54 GMTBob Harman

A long time field collector friend working the Southwest Harrodsburg road cut in May 2005 found this large geode specimen. Now in my collection, it is today's favorite and one of my best....... period! It measures about 20 cm x 18 cm and weighs over 7 kg! There is a very lustrous color zoned and gem quality barite measuring about 4.8 cm x 1.5 cm x 0.5 cm thick and a nearby isolated and perfectly terminated 6.5 cm x 2.3 cm calcite rhomb. Several hi end dealers suggest sacrificing the geode and trimming the specimen to make just the 2 crystals on quartz specimen. They think it would significantly enhance the monetary value, but I will keep the geode intact as is (I have the whole geode including the cap).

17th Jan 2012 15:08 GMTJoseph Polityka Expert


Great barite specimen; they are so hard to find undamaged. Many years ago I collected in the area with Harry Sering an Indianapolis area dealer. He found a few things but I didn't have much luck that day.

Very few collectors, to my knowledge, have good specimens of these American classics in their collections.

By the way, did you know Harry Sering? He eventually moved his business to Morgantown and passed away in the early 1980s. He was the person responsible for bringing in about a ton of those Dravites from Yinnietharra, Australia in the late 1960s and actually bought the entire production. from the miners.

Best wishes,

Another great specimen from the Heartland! Thanks for posting.

Here is a geode from the location on Rt.37 north of Bloomington in Monroe County, Indiana that produces the aragonites that are so well known. The specimen contains a typical assortment of calcites and dark brown ankerite or ferroan dolomite with a coatings of calcite and or aragonite. The large, cleaved calcite is greenish because of hundreds of contained very fine filaments of altered millerite. Millerite from this location seems to be most abundant in a small zone where it is almost always enclosed in late calcite but ranges in alteration stage from bright, unaltered to greenish to a medium orange color. We speculated that the abundance of Ni in the area might be related to concentration by organisms prior to consolidation of the sediments.

Larger section is 8x6x6 cm. Circa 1965

Having a large and complete Indiana geode collection demands some specimens that are more visually interesting than visually stunning. These 3 pix are of Indiana geodized fossils. They have been described several times in the recent past including a Rocks and Minerals article several years ago by Jeff Smith and a description in the late June Culp Zeitner's book on geodes. They are quite common at several locations where I field collect and at other private land and non-collector allowed locations in Southern Indiana. Several species of shells, brachiopods, gastropods, horn corals and crinoid stems, a crinoid head and a cephalopod are shown. Some of these show portions of the original fossil shell, making for jigsaw puzzle like surfaces. These specimens vary in size from 1" to 5", but at other sites they can be greater than 1 foot in size. These geodized fossils are most often solid, but occasionally they are hollow and contain beautiful quartz crystals. Recognizing that these are not one specimen, I prefer to treat them as one related grouping and they are my favorite of the day. Enjoy.....and great pix everyone!!

Gale, what a great rhodo! One can really appreciate what a rare thing this represents when checking some of Rock's picture posts. And anyone can get a more detailed idea of what is involved by accessing his website for a great travelog about one of his trips to SA.

Great geode-fossils, Bob. For the most part while collecting in Indiana when we found a decent fossils we traded them for minerals but this one crossed the boundary into the mineral realm. The sphalerite replacement has minor alterations to smithsonite and the interior shows a coiled structure that may be part of a spiralia. Some original shell material is present on both anterior and posterior surfaces. From the Harrodsburg Limestone, aragonite cut, SR37 North of Bloomington. 9x5.5x4 cm. Circa 1964.

Incredible specimens being shown again, especially your Aqua Gail, I really do have a soft spot for Pakistani minerals.

Strange little Tourmaline from Paprok, Afghanistan. A first for me where the host almost seems to outshine the specimen.

20th Jan 2012 09:04 GMTAM Mizunaka Expert

Calcite knob with celestine from Mexico. 6 x 3 x 2.7 cm.

20th Jan 2012 17:14 GMTBob Harman

Although I self-collect and specialize in Indiana geodes, occasionally I buy other geodes. This huge Madagascar celestine geode tweaked my interest at the 2002 Tucson show. The exterior measures 26 cm x 22 cm; the interior cavity measures 20 cm x 17 cm and the doubly terminated crystal towards the front measures 9.5 cm x 1.7 cm. The geode weighs 20 kg (about 45lbs)! As we had flown to Phoenix that year, my daughter who lived in Phoenix that year, "baby sat" the specimen for 6 months till we drove out there later in the year; then we took it home. It was difficult for me to photograph as there was little contrast between the blues on all the crystals. Like amethyst cathedrals from Brazil, there often are a million of these celestine geodes to choose from at many of the larger mineral shows. This one has always seemed to me to be better than all the rest. Many mediocre examples are really overpriced; if buying one, make sure the main crystals are centrally located and stand out without dings and the whole cavity is well and evenly displayed. A recent article in Min Rec discussed these specimens with many pix of geodes and cropped crystal specimen portions from some of them. MY FAVORITE OF THIS DAY ENJOY!

20th Jan 2012 19:16 GMTStephen Rose Expert

That is a nice celestite geode, Bob. I wonder how many that size are under water at the Lehigh quarry now?

Today my post is of a somewhat battered copper in calcite from Northern Michigan. This specimen belonged to my grandfather who died in 1943. Sometime between then and 1949, when my grandmother died and the family home was sold, my eldest sister selected a few things that pleased her from his cabinets and these specimens ultimately became mine. The bulk of his collection was, quite literally, taken to the dump.

Copper in and on calcite, Michigan. 3.5x3x3 cm.



20th Jan 2012 22:53 GMTBob Griffis Expert

Great specimens, all. I just discovered the "Follow Topic / Email me about replies to this topic" checkboxes turned off again (at least 5th time since thread started). Anyone else having this problem?

21st Jan 2012 19:36 GMTStephen Rose Expert

This specimen was part of a trade with Harry Sering in 1966. Murdochite with rosasite and aurichalcite, Mina Ojuela, Mapimi, Durango, Mexico. 9x6x3 cm.



21st Jan 2012 23:18 GMTPaul De Bondt Manager

Hi all,

Very nice specimens, thanks for shearing.

Bob, I had it a few times also. I had it on other topics too.

I just submit again untill it turns off again.

I hope this helps.

Take care and best regards.


22nd Jan 2012 01:03 GMTBob Griffis Expert

Here's a specimen that is pretty rare....and my favorite today.


Tom Scott Mine, Turquoise District (Courtland-Gleeson District), Dragoon Mts, Cochise Co., Arizona, USA

137 x 103 x 91 mm overall. This large dendritic Aragonite is from the lesser known Tom Scott Mine, just adjacent to the Defiance Mine in the town of Gleeson, Arizona. Multiple stalactitic forms are lightly copper stained giving the specimen a nice bluish cast. From the Ron Gastil collection, this specimen was acquired by him in the mid 1970s.


22nd Jan 2012 21:06 GMTJay Buscio

Azurite, Copper Queen Mine, Bisbee, Arizona. Measures 8 x 6 x 3.5 cm

23rd Jan 2012 21:23 GMTSteve Sorrell Expert

One of my favourite blue hues - cornetite from the Great Australia Mine, Cloncurry, Queensland...



24th Jan 2012 15:58 GMTDenny Lawing

This is one that I pick up at an estate sell a few years back. A very fine Pyromorphite

Bunker Hill Mine Shoshone County, Idaho

25th Jan 2012 04:54 GMTCraig Mercer

A little Pakistani Pollucite from me today.

25th Jan 2012 05:36 GMTBob Griffis Expert

I am beginning to believe this is one of my favorites every day....

Linarite, Quartz, Mottramite

Chance Mine, Mono Co., California, USA

This is the best specimen to come from the commercial mining effort completed in 2004 by John Seibel, Steve Perry and myself when I owned the mining claim. The specimen is 11.9 cm in its longest dimension, and the largest linarite is a complex crystal group approximately 4 cm in length. This one I decided to keep.


27th Jan 2012 04:05 GMTGail Spann Manager

Amazing minerals everyone, really a delight to see what you enjoy as your favorite of the day!

I had the pleasure of hosting an Aussie this week, so got to hear a bit about being a collector in Australia. Trevor Kitto, he's gone on to Tucson now. His being here made me stop and enjoy a shelf of Smithsonite that we put together a while ago. Here is that photo, a group of various pieces. Enjoy.

27th Jan 2012 22:23 GMTStephen Rose Expert

I've always liked this little pyrite from the Leonard Mine, Butte, Silver Bow County, Montana. Circa 1960's. 4 cm tall.



28th Jan 2012 00:52 GMTGail Spann Manager

My newest fav! Cavansite.

28th Jan 2012 05:56 GMTXiao-dong Xu

A pretty thumbnail specimen of Kottigite with sprays of crystals measuring 1.5 cm across.

28th Jan 2012 06:39 GMTBob Griffis Expert

Today's favorite is a new acquisition from Tuscon...


Malbunka Copper Mine, Gardiner Range, MacDonnell Shire, Northern Territory, Australia

97 x 50 x 48 mm overall. Two distinct balls of Azurite, measuring 26 x 21 x 20 mm and 20 x 17 x 15 mm. Collected in summer of 2011 by Dehne McLaughlin and Maureen Hughes from a small zone. Few of these were found.


30th Jan 2012 01:47 GMTGail Spann Manager

Xiao-dong Xu, really very beautiful

30th Jan 2012 02:01 GMTJohn A. Jaszczak Expert

I just couldn't pass up this cute 1.2 mm sperrylite from Dave Joyce's recent offering. What fun to photograph! Lustrous crystals are challenging to photograph.

31st Jan 2012 02:27 GMTGail Spann Manager

Love this, new to our collection a year ago.

The Erongo rabbit ears is what we call it. Smoky quartz, schorl on microcline. Erongo mountains, Damaraland, Erongo province, Namibia.

Overall size 9.5 cm by 9.6 cm by 8.7 cm.

Longest crystal is 84 mm.

31st Jan 2012 16:17 GMTBob Harman

Very collectible Indiana calcites are widespread in many quarries and also in geodes. This 6 cm x 6 cm honey colored calcite is typical for those found in the Berry Materials Quarry, North Vernon Indiana. The quarry was a long time favorite for Indiana calcite collectors until operations largely ceased there several years ago. Not positive, but the site may now be extinct.

1st Feb 2012 09:35 GMTXiao-dong Xu

From: Coldstones Quarry, Greenhow, Yorkshire, UK

Size: 3.5 x 2.3 x 1.8 cm

Glassy clear fluorite cubes with distinctive blue edges and spots to the faces. Some areas are covered with a tan coating of hemimorphite.

1st Feb 2012 11:57 GMTGail Spann Manager

1st Feb 2012 16:01 GMTDebbie Woolf Manager

Gail that's a very nice Erongo combo ... Is Damaraland on the label ? If so you may need to change it as it's an old name for an area now divided into two regions.

1st Feb 2012 16:19 GMTJoan Kureczka

New acquisition this week, showing its fluorescent side -- Boltsburn Mine, Weardale.

1st Feb 2012 17:16 GMTSteven Kuitems Expert

Hi Joan, the mirror surfaced fluorite is definitly a WOW !! Fluorecsence I believe was first observed in the sunlight viewing fluorite from the natural ultraviolet rays in sunlight.



1st Feb 2012 18:53 GMTJoan Kureczka

Steve -- yes, and it was Weardale fluorite that was being described.

1st Feb 2012 19:17 GMTRoger Curry

Wonderful specimen Joan! I live only 30 miles from the Boltsburn mine, and so have a great interest in Weardale fluorites. Lovely fluorescence and clarity. What is the colour when backlit? Any info on when it was mined, and its history? I would love to see more photos....



1st Feb 2012 22:51 GMTJoan Kureczka

Hi Roger -- Jesse took the photo in Tucson and I haven't seen it yet in person myself, but it's a typical Boltsburn purple color when not light up by the sun. I don't know if there is any specific history on the piece; it was previously in a French collection. The mine closed in 1932 though, and most of the fluorite specimens came out between the 1890's and then. So it's an old historic piece in any case.

2nd Feb 2012 05:08 GMTXiao-dong Xu


Strange Vanadinite crystal on Goethite.

Locality: Taouz, Er Rachidia Province, Meknès-Tafilalet Region, Morocco

Size: the Vanadinite in photo is about 5mm long.

A fine stalactite of goethite is topped with two red orange vanadinite bowties. Unfortunately, the goethite was broken during shipping.

2nd Feb 2012 05:11 GMTGail Spann Manager

Thanks Debbie, will investigate as it is an old label.

6th Feb 2012 06:08 GMTXiao-dong Xu

Sweet Home Rhodochrosite

Size: 6.1 x 3.3 x 2.1 cm

The Rhodochrosite crystals on this specimen have good red color with excellent sharpness and gemminess. They are associated with minor cubic purple Fluorite on thin "needle" Quartz crystals on sulfide matrix.

7th Feb 2012 09:02 GMTGail Spann Manager

I'm in Tucson nd will have many more favourites of the day when I gt home!

7th Feb 2012 13:14 GMTXiao-dong Xu


From: Huachocolpa Mine, Peru

Size: 4 x 3 x 3 cm

Eye-catching piece of flower-like Rhodochrosite.

7th Feb 2012 15:11 GMTDarren Court

What an absolutely stunning Rhodochrosite, Xu, thanks for sharing it! Cheers!


7th Feb 2012 17:50 GMTBob Harman

In March 2010 I was self collecting at the Harrodsburg road cuts in Monroe County Indiana (see pix on page 12 of "The Nature Thread") when I peeled away a large slab of ordinary appearing limestone. The back side revealed a half of an oval geode with the remaining and better half still firmly remaining embedded in the limestone rock wall. Eleven months later, in February 2011 further freeze/thaw activity had loosened up this remaining better portion and it was easily removed. It is pictured here at 15 cm x 9 cm and has many groupings of cream colored thru red-orange dolomites.

8th Feb 2012 01:44 GMTGail Spann Manager

Okay so it's not a mineral, but it is my favourite of the day!!! All in fun, cheers!

The ever energetic Dave Wilber doing "The Gail" face.

8th Feb 2012 05:34 GMTAM Mizunaka Expert

Today's favorite is a glassy cluster of citrine on danburite from Mexico. 11.6 x 7.3 cm.

9th Feb 2012 16:23 GMTGerhard Brandstetter Expert

Back again. Good to see so many good things here! I'm happy to present you one of my really personal favourites - i think this combination makes it extraordinary! Have you ever seen a similar - from any place in the world?

Gold wires in Uraninite - 25 mm. On the left side you see a small red area of Cinnabar. Around this area the gold has a high mercury content - called Goldamalgam (natural - not manmade!). Rare Stuff - and highly radioactive of course.

14th Feb 2012 04:14 GMTStephen Rose Expert

There was a bit of snow here this morning, just enough to get the skiers excited. So, a white mineral.

Natrolite from the Chimney Rock Quarry, Bound Brook, Somerset County, New Jersey. 10.5x1.5x1 cm. From Jewel Tunnel Imports, 1975. Thanks, Rock!



19th Feb 2012 20:11 GMTStephen Rose Expert

A good example of Indiana sphalerite from the Berry Materials quarry at North Vernon, Jennings County. The well developed tetrahedral crystals are formed on massive sphalerite with a bit of sandy matrix incorporated in the back of the specimen. Overall size:11.5x6.5x3.5 cm. Circa 1966.



19th Feb 2012 22:13 GMTBob Harman

Another favorite Indiana quarry for calcites was the Meshberger & Sons Quarry about 7 miles SE of Columbus, Indiana in Bartholomew County. It is still active, but apparently is currently operated by collector unfriendly management. Many great and large calcites were collected in the 1960s and early 1970s. Little to nothing (to my knowledge) has come out of there since before 1980. Even when the quarry is inspected, many of the folks must remain in their vehicles and (again to my knowledge) no individuals or clubs have gained access to the quarry in over 35 years. This 10.5 cm x 3.5 cm honey colored and partially double terminated crystal is surrounded by several smaller accessory crystals on the dolostone matrix. The photo also shows a small contact from the vug on the "top" of the crystal. This appearance is typical for the larger crystals found in the 1960s.

21st Feb 2012 00:04 GMTAM Mizunaka Expert

A glassy barite cluster with calcite is today's favorite from the Meikle Mine in Nevada. 9.1 x 7.4 cm

21st Feb 2012 02:10 GMTGail Spann Manager

AM, your minerals are stunning!

21st Feb 2012 05:25 GMTLinda Smith

This is what I collected while in Arizona for the Tucson Gem and Mineral Show. A self collected Creaseyite from the type locality. A micro, but a pretty little micro. It is my favorite for sure today. Thank you Robert O Meyer for photographing it.

21st Feb 2012 11:50 GMTMichael Hopkins

My favorite today and new from the show!

21st Feb 2012 22:07 GMTStephen Rose Expert

One I've had for a while. I purchased this specimen for $3.50 at the Midwest Federation show in Rock Island, Illinois in 1967.

Sharp, twinned, pseudohexagonal aragonite crystals with small calcites coating some surfaces. The base of the specimen contains sulfur. Agrigento, Agrigento Province, Sicily, Italy. Overall size: 11x7.5x4 cm. Largest crystal 3x3 cm on face.



23rd Feb 2012 14:00 GMTGail Spann Manager

Diaboleite, Mammoth Mine, Arizona. 78mm

My favourite today! Am still recovering from Tucson. Have lots of new minerals to photo and share.

24th Feb 2012 00:43 GMTAM Mizunaka Expert

Gail Spann Wrote:


> AM, your minerals are stunning!

Thanks Gail.

Today's favorite is a mate to the Meikle barite specimen. A glassy cluster of calcite. 7.9 x 4.6 cm.

25th Feb 2012 05:04 GMTStephen Rose Expert

Looking at slides from times past and couldn't resist making this one my favorite of the day.

Digging concretions near Edgemont, Fall River County, South Dakota in 1979. These smaller concretions seemed to have relatively more open space for development of calcite and baryte crystals. The happy collector now has children nearly the same age he was here.



25th Feb 2012 17:24 GMTNeal Luppescu

I just started photographing my new pieces.

Here's one from the Minerva No. 1 Mine, Hardin County, Illinois

6 x 10 x 7 cm

26th Feb 2012 15:53 GMTNeal Luppescu

This Willemite from Tsumeb is quite appealing. It is mainly reddish-brown, with a bright blue stripe passing through it. I am told the the reddish-brown variety is Mn-rich "troostite." Does anyone know what the chromophore is for the blue variety? My guess would be copper, but it's just a guess.

4 x 5 x 3 cm

27th Feb 2012 23:05 GMTStephen Rose Expert

A baryte from the Cartersville District, Bartow County, Georgia. Overall size 9x6x4.5 cm. Circa 1965.



28th Feb 2012 06:59 GMTAM Mizunaka Expert

A cluster of lustrous amethyst crystals from Mexico is today's favorite. 5.4 x 6.5 cm.

1st Mar 2012 00:57 GMTNeal Luppescu

Here's a Calcite dusted with Duftite from Tsumeb. A very nice grouping of crystals in parallel growth.

I wish I could get my photos as sharp as A.M. does. :-(

5 x 9 x 6 cm

1st Mar 2012 01:18 GMTDr. Paul Bordovsky

I agree Neal. A.M. does a great job.

I've been wondering: better optics, better sharpening algorithm, or just plain better minerals?...


Neal Luppescu Wrote:

1st Mar 2012 03:04 GMTAM Mizunaka Expert

It's a combination of optics, optimum aperture, lighting, and a little sharpening that culminates in a crisp image.

Having a nice mineral to start with doesn't hurt either ..... :-D

Quartz, Ace of Diamonds Mine, Middleville, Herkimer Co., NY. 9.5x6x2.5 cm. Circa 1980.



1st Mar 2012 06:43 GMTStephanie Martin

It's been a while. Enjoying all the beautiful specimens. Thanks one and all for posting.

Linda, that is a lovely creasyite, photo makes for a very pretty garden! A nice scene on a winter's day.

Neal - as usual your specimens are outstanding.

AM - you continue to set the bar for others to admire and aspire.

Stephen and Bob, great depth of classics. Enjoying your new thread as well.

This is a little tidbit that just came in the mail. The label made me smile as it indicated it was a piece from the type material, an unexpected bonus and now my favourite of the day. From Al Falster.


La Esperanza Mine, Durango, Mexico

overall specimen size 12mm



1st Mar 2012 08:41 GMTPeter Andresen Expert

Stephanie, that's a beautiful esperanzaite, and photo. You should upload this to mindat, and I'm shure it will be the mineral page photo!


1st Mar 2012 13:47 GMTStephanie Martin

Thanks Peter, yes I will upload it. I just want to clean up the photoshop a bit first, it was late and I rushed it a bit.


stephanie :))

1st Mar 2012 15:08 GMTGail Spann Manager

Here's mine for today. Been busy with lots of house construction here, and destruction...oh, and throw in mayhem while we are at it. ha ha!

Anyhow, the mineral that brought me into the collecting world....

1st Mar 2012 22:13 GMTJelmer Hylke Hoeksma

Hello again,

It's been long since I posted a specimen as I had to return the laptop from my former employer.

I hope this new picture from a nice rutile with hematite from Novo Horizonte will appeal without the usual postproduction.

She measures 4,5 by 4 centimeters.

3rd Mar 2012 06:31 GMTStephanie Martin

Jelmer, Wow, that is a fascinating rutile spray on so many levels!

I was really smitten with this cowlesite when I received it. Nicely speckled with calcites. A favourite for days!

From Trevor Boyd.


Fallowvee, Waterfoot, Co. Antrim, Northern Ireland, UK

vug approximately 15mm long, overall specimen ~ 6 x 5 x 4 cm

3rd Mar 2012 20:17 GMTStephen Rose Expert

A specimen I remember .......

This fine albite (variety clevelandite) specimen was purchased from Jose de Estrada, a mineral dealer in Taquaral, Minas Gerias, Brazil in 1988. In the matrix are several large gem lepidolite crystals. It measures about about 35 cm horizontally. This was hand carried back to the US and when processed through customs the agent looked at the heavily wrapped and taped bundle, asked what I did for a living (geologist), and upon hearing the answer, warily shook his head and waved me through. I believe that this specimen now resides in a museum in Connecticut.



4th Mar 2012 01:24 GMTJelmer Hylke Hoeksma

And for today a scolecite flower on chalcedony from Maharashtra, India.

The color fidelity is not one hundred percent, the color of the scolecite is more towards a brownish red.

Measurements are; 8 by 5 by 3 cm.

4th Mar 2012 23:48 GMTStephen Rose Expert

OK, Stephanie, I am going to post another 'classic', even if it seems like just yesterday when I first saw it and it was produced sometime more than 30 years ago. I guess that we can't fight the clock.

Tabular smoky quartz with rutile, Ibitiara, Bahia, Brazil. Ex R. Thompson collection. T. Rose specimen and photos. This is a floater with just a minor point of attachment on one corner. Overall size: 10x7x3.5 cm.

End view....

Great rocks, Jelmer and all!



5th Mar 2012 01:46 GMTNeal Luppescu

I'm doing a little better with the camera now. My favorite today is a cluster of round rosettes of azurite, partially pseudomorphed to malachite, from Seabra, Bahia, Brazil.

7 x 9 x 4 cm

5th Mar 2012 06:03 GMTStephanie Martin

Jelmer, that is an unusual and alluring scolecite blossom! Perfect presentation!

Stephen, rutilated quartz is always a classic. Yes, you can't beat the clock. It's just alarming (pardon the pun) to recall things not in years. but in decades. Seems like yesterday.

Neal, great job on the photo, a gorgeous Brazilian beauty!

My favourite today is going to be a favourite forever. It was a birthday gift from my brother who snapped it up at the London, Ontario show while I wasn't looking (the rascal). It came with an old yellowed typewritten label, so it has been around. It doesn't sparkle like a blue zircon or tanzanite gemstone, but it is still a gem in my eyes and I will cherish it always.


San Cristobal District, Yauli Province, Junín Department, Peru

specimen size ~ 15mm x 10mm, main crystal ~5mm

5th Mar 2012 07:05 GMTPhilip Perkins

Stephanie was Stephanite named after you or you after it? LOL great to see your specimens, thanks for sharing.

5th Mar 2012 07:50 GMTAM Mizunaka Expert

Today's favorite is fluorite on quartz on fluorite from the Rock Candy Mine, British Columbia, Canada. 10.6 x 9.2 cm.

6th Mar 2012 03:01 GMTGail Spann Manager

Goodness gracious, some amazing minerals and amazing photos! How nice to see everyone posting, thanks!

6th Mar 2012 07:14 GMTStephanie Martin

Hey Philip ~ you're too funny... stephanite was named in 1845, I know I'm getting older, but last I checked I'm not quite THAT old. hehe :-D.

Having a little fun tonight...

A "Me and Mini Me" staurolite.

I wish I may, I wish I might... oh never mind !!!


Pestsovye Keivy, Keivy Mountains, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia

Larger one is ~ 9cm x 7cm, smaller one is ~ 1.5cm x 1.2cm

7th Mar 2012 21:22 GMTRonald J. Pellar Expert

Here is my favorite for the day. Got it at Tucson this year. It is an Alabandite, 25 x 25 x 21 mm and is from Uchuchacchua Mine, Lima Dept., Peru.

9th Mar 2012 00:55 GMTNeal Luppescu

What is it, Ron. Alabandite? Spinel? I'm having a hard time identifying it.

9th Mar 2012 04:55 GMTXiao-dong Xu


Celestite and Calcite

From: Wessels Mine, Northern Cape Province, South Africa

Size: 3.5 x 2.5 x 2.4 cm

A quite exceptional, pearly, silver-blue Celestine. The habit is so unusual: fine blades rotate through spheres. Just beautiful.

9th Mar 2012 07:11 GMTTimothy Blackwood

My favorite of the day:


8.6 x 5.4 x 4.6 cm. Several thick, lustrous, translucent, red-orange crystals to 1.5 cm on gossan matrix. This specimen is from the James Webb Collection of Houston, Texas, and was collected by Wayne Thompson in 1993.

10th Mar 2012 16:57 GMTGail Spann Manager

Great photos!!!

We added a couple of tourmalines while in Tucson.

10th Mar 2012 21:33 GMTJelmer Hylke Hoeksma

My favourite for today is a difficult to photograph spessartine from Brazil. (2,6 by 2,1 by 2,0 cm)

The big challenge is to show both the great colour and the magnificent structure of these specimen.

In most of the pictures I took one of both is excellent displayed but the other one is under exposed.

The picture I choose was the one that, in my opinion, was best balanced.

11th Mar 2012 08:11 GMTStephanie Martin

WoW, beautiful stuff, Folks!

Today my favourite is a location piece. A year ago a tragedy unfolded in Japan. My thoughts still go out to the people of Japan and their continuing efforts to rebuild their lives and their country.

This is not a specimen of beauty but it is a rare earth mineral that hails from the stricken prefecture that was obtained prior to the devasation.

It is the greenish coloured material at the top of the piece. And yes, will upload it as none are in the database.


Fusamata, Kawamata, Fukushima Prefecture, Tohoku Region, Honshu Island, Japan

overall specimen size ~10mmx 5mm

11th Mar 2012 13:41 GMTGail Spann Manager

A piece we got from Peter Lyckberg a few years ago.

11th Mar 2012 17:27 GMTGail Spann Manager

Okay, couldn't resist having another favourite as JIm is cataloging and I took photos of these two beryls from Madagascar. Papa and Mama Beryl.

13th Mar 2012 05:26 GMTPhilip Perkins

Gail I think your Madagascan Beryls are fantastic, love your Calcite too.

Todays favourite is an Epidote.

Skardo, Pakistan.

size is 7.5cm high.

13th Mar 2012 14:15 GMTJonathan Woolley

I agree, Gail, I love the new beryls.

Since you've got a Mama Beryl & Papa Beryl, you just need Baby Beryl and a heliodor to complete the fairy tale: Goldilocks and the Three Beryls! :-D

13th Mar 2012 16:04 GMTJoan Kureczka

Nice beryls indeed.

I haven't posted anything for awhile, so how about this -- nice fluorite from El Hammam, Meknes, Morocco picked up in Tucson last month. 11x 7x 2.5.

14th Mar 2012 04:26 GMTPhilip Perkins

Hi Joan.. That is a very special Moroccan Fluorite, i really like it, is the other mineral Calcite?

Todays special piece for me is a Topaz.

Mogok, Myanmar.

Size 7cm tall x 4.5 wide.

Here's a Spodumene var Kunzite that I fell in love with at the University of Arizona last year on the Obodda exhibit. It was one of those that came up for sale in the Arkenstone this year. I was running late on the opening day and when I went in I made my way, through the crowds, to get to the case and tell them I wanted this. Phew, it was still there.

It was found in three pieces that they discovered fit together.

17th Mar 2012 06:14 GMTStephanie Martin

Awesome specimens everyone! Spectacular pieces!

AM - that cerussite is understated elegance. Wow.

My favourite today is a simple specimen of apophyllite. I really like it because the crystals are larger than is typically seen from this location.

As an added bonus it came with a label from David Shannon Minerals, dated 4/85.

can you believe that i picked it up in China for $60? it measures 6.5 x 6.5cm.

18th Mar 2012 05:00 GMTPhilip Perkins

I know i'm being very naughty posting a second time, Gail please before don't whack me too hard,

i was having a lazy Sunday afternoon taking pictures & was excited how this one turned out,

Rutilated double terminated Quartz from PAKISTAN not Brazil

i found it in Tucson this year, shortly after acquiring it a dealer friend said that he had never seen a Rutilated Quartz

from Pakistan before.

size is 6.5cm long, looked like a Japan law twin tried to grow but ran outta steam.

18th Mar 2012 05:19 GMTJoan Kureczka

Philip, the ferberite and fluorite piece is lovely. Great specimen/great price.

The rutilated quartz is also very interesting. Not surprising to find that they are produced at that location, but not something one often sees.

Very nice finds, both.

18th Mar 2012 18:12 GMTTimothy Greenland

Todays favourite - 'Cos I collected it exactly 50 years ago (18th March 1962) at the Blagill mine. A Happy Birthday snap; the FOV is about 7 x 6 mm. Barytocalcite...

Many thanks to all for the lovely photos and stories.



19th Mar 2012 03:42 GMTStephanie Martin

Thanks for the kind words Gail. Sometimes things just come together at the right moment.

Timothy, congrats on your semi-century birthday specimen! Obviously it was a keeper!

I have never really collected much orpiment but something about this piece peaked my interest. The sparkling calcite makes for a nice backdrop. I was pleasantly surprised to find a few tufts of picropharmacolite that I didn't notice until closer inspection as they were hiding in the vug.

My fave for the day - Zeolite from Poona, India

19th Mar 2012 13:00 GMTStephanie Martin

Hi Amanda, what you have there is a very nice calcite coated in quartz druse, so these would not actually be zeolites. There is a tendency to label all the material from India as zeolites, however there are many shipped out with the zeolites that are not. Some examples are apophyllite, prehnite, okenite, calcite, chalcedony, these are not zeolites. I just love Indian calcites and chalcedonys. Nice specimen in any case.

Great photos Folks!

I thought I would join in and dote on more epidote... my latest favourite that just arrived last week.

An interesting formation that I have named "Heart of Garnet" (alluding to "Heart of Darkness"). These epidotes radiate around almandine centres and make for a flower-like appearance. There is another smaller one on the back. Ex. Bill Plavac (via Doug Wilson).

Today's fave:-

Bournonite, Cornwall, UK (mine unknown at the present)

21st Mar 2012 11:22 GMTPaul De Bondt Manager

Hi all,

Fantastic favs, thanks for shearing.

Amanda, when I look at the picture of the bournonite, on the right side, it seems that there are some tetrahedral crystals and they seem coated with chalcopyrite. If that's the case, then only the Herodsfoot is the locality. If not, the only possible locality, IMHO, would be Wheal Boys. All the other mine gave, to my knowledge, only poor and small flecks and patches.

Otherwise, try to see what the associated minerals are. Allways ready to help.

I hope this helps.

Take care and best regards.


21st Mar 2012 11:40 GMTAmanda Hawkins

Hi Paul

Thanks so much! Yes, it does look like there are some Tetrahedrite crystals on the right. I shall take a closer look when i unpack it. We are all packed up ready to move back down to Cornwall, so can't access it right now. I'm sure it's from the Herodsfoot Mine :-)

21st Mar 2012 20:17 GMTPhilip Perkins

Amanda What is the other mineral with the Bournonite, is it Barite? i'm not quite sure.

Good luck living in Cornwall.

Thanks Philip! My photo label says Quartz, but I need to check that is accurate with my expert, will get back to you on that one.

23rd Mar 2012 04:26 GMTStephanie Martin

My favourite today is this specimen of chalcedony stalactites. Thankfully they arrived without damage. These caught my eye as they have a frond-like appearance that makes me think of swaying tendrils in an ocean current. Can't help myself but I have to borrow a pun ~

with fronds like these, who needs anemones?

Quartz var Chalcedony

Nasik District, Maharashtra, India

specimen size ~ 5cm x 6cm

"fronds" to 6cm

23rd Mar 2012 11:34 GMTPaul De Bondt Manager

Amanda, Philip and all,

The white mineral is quartz but on a closer look, it could reveal that they are quartz pseudomorphs after baryte crystals.

They can rarely be observed through the county. Nice specimen and combo.

I hope this helps. I wish you the best in Cornwall too.

Stephanie, that's one gorgeous chalcedony. I am fond on that " ordinary " mineral.

Take care and best regards.


23rd Mar 2012 11:39 GMTSteve Sorrell Expert

Hi all. It's a pain not having decent internet. Can't even browse let alone post. Hopefully that is now all behind me.

This is a nice little elbaite that I found at Tucson. I didn't realise that the tip was blue until I got it in the right light. I thought it was just dark. A bonus.



23rd Mar 2012 17:55 GMTVincent Rigatti

I love this perfect little fluorite from Walworth, NY, on dolomite. 3 x 4 x 4 cm. I was reminded the other day when it fell out of my hand and landed perfectly upright on my thick sock.......whew.

24th Mar 2012 03:58 GMTRay Hill Expert

Hi Stephanie....just love those chalcedony stalactites..just gave a talk on mineral treasures of the world to a group of patrons of a local regional library and one of my personal collection pics was of an open geode with a perfect zeolite crystal supported by a see of these exact type of chalcedony stalactites...thanks for sharing.

24th Mar 2012 06:19 GMTStephanie Martin

Thanks Paul and Ray. Chalcedony may be an ordinary mineral, but it can form to make extraordinary displays. I have always had a fascination for stalactites. Ray that sounds like a fabulous geode you have there. I have a number of such type myself with varying combinations of heulandite, stilbite and apophyllite. I never get tired of looking at them, but they are darn difficult to photograph!

Steve, I checked my Stak Nalas after you said that and lo and behold I found a blue tipped one too. Yours is gorgeous.

Vincent, a lovely Walworth fluorite, glad your sock-covered toes broke the fall. Phew, that was close!

I have really been appreciating all the non-zeolites that come from India, particularly the interesting varieties of chalcedony and calcite formations.

My fave today is a bi-coloured calcite, wrapped in a wreath of gyrolites, on quartz druse.

Thats a wonderful Elbaite Steve, i found it's big brother in Tucson, with three Elbaites with Albite & Quartz, haven't taken photos yet.

Vincent your blue Fluorite is truly fantastic, love the gemmy blue Fluorite,

One time in Tucson i was looking at an Arkansas Japan law Quartz, when i handed it back to the dealer he dropped it & it hit the top of his shoe & bounced onto the carpet under his table, thus saving it, i always regretted not buying that specimen, it was wonderful.

25th Mar 2012 06:22 BSTStephanie Martin

It's time for another favourite. I took a few more pics so you will all have to put up with me for a few more days :-D

Going through some Pakistan material I took a moment to revisit this translucent purple sapphire in matrix. It is also fluorescent and glows a nice red in LUV.

I have been working on breaking up, photographing, and cataloging some self collected material (ok collected with my daughter Jessica). I am finding this locality I am working on now interesting.

Nontronite (small balls) at this locality usually changes from its initial color to black very quickly when exposed to sunlight. Apparently, however this change does not always occur. Here is a calcite crystal that has grown over several nontronite balls. The trapped balls are blue, whereas the exposed ones are black. At the top of the calcite crystal, however, there are several nontronite balls that are half blue and half black!

Thanks for looking


1st Apr 2012 23:57 BSTJames McGuire

My favorite of the day is a thumbnail I picked up at one of the Tucson satellite shows this year. It is a red beryl with small bixbyite cubes in association on rhyolite matrix, from the Thomas Range, Utah, USA. It is about 1.6 cm tall, and still needs some cleaning/prep work. The color, luster, and quality are quite nice for a Thomas Range red beryl (as opposed to the more commonly seen Wah Wah Mountains, Utah red beryls).

2nd Apr 2012 17:52 BSTStephen Rose Expert

Thanks everyone for sharing your faves. Always enjoyable.

Last week I went to my first mineral show for the year and picked up this interesting location piece. At first I thought this was a radiating shorl specimen but was surprised to see the label as stibnite. The location was unusual so it had my curiosity and decided to take it home. This was from Doug Wambold who self-collected it back in 1978 when he was living in New Zealand. He told me the location where this was found was a former gold workings but is no longer there and is now a road. The yellow coating may be cervantite. My fave for the week!

Posting the egg reminded me of something else I have called "Birds Nest Opal".

These are geodes lined with opal and/or chalcedony. They get their name from their appearance.

I am assuming these are opal-AN, they are very fluorescent. Obtained from Jeremy Fuller.

I'm not sure what this calcite is trying to be, but it does somewhat remind me of a maze. Perhaps if it had more time to grow, it may eventually have joined itself, with a result looking rather like an Escher drawing. Another example of the interesting variety of Indian calcite forms.

21st Apr 2012 04:26 BSTDon Windeler

Great stuff, all.

Stephanie, I may be over a week late on the posting, but that Nasik calcite is flippin' cool. I'm a big fan of specimens with lots of right angles and such -- as well as calcites of all kinds -- and I've never seen anything like that one. Excellent pick!

It's killing me that I don't have a real photo set-up right now, as I'd love to post a few items. Not that things are lacking by my absence, as there's excellent rocks on display pretty consistently these days...



21st Apr 2012 06:54 BSTStephanie Martin

Neal, it is always a pleasure to see your superb specimens. That Topaz is outstanding. Great work with the camera too!

Paul that hot one is sure pretty. Very nice indeed.

Don, glad you liked the calcite. I can't seem to get my fill of them.

If you liked the calcite you might like this andradite that recently landed from the locale du jour, Inner Mongolia. I obtained a few specimens and the colours vary from medium green to black with mirror lustre. On this one they are actually a dark green and have high lustre depending on the angle of lighting.

Haven't been around much as I am taking care of a terminally ill parent. But we did manage to recently get this piece. It is just at the beginning of the American Treasures book. Jackson Crossroads Quartz var Amethyst.

29th Apr 2012 04:43 BSTRyan L. Bowling

Since there is a quartz theme going, and it has been sometime for me, here is a nice one for the day. Absolutely outside of the size I collect, I just love the piece, so I have kept it all this time!

Quartz Faden

Wana, Waziristan, Pakistan

5 1/2 inches tip to tip.

Great photos, and pieces everyone.

29th Apr 2012 06:54 BSTPhilip Perkins

Nice Faden Quartz Ryan, i also thought it was to large for your collection, i know the solution to your problem....


As the theme is Quartz, this is my contribution,

Quartz cluster, Sichuan Province, China.

size is 15cm high x 14 across, the longest crystal is 15cm, all crystals are double terminated,

it was a floater, the miner said that they just lifted it out of the vugh, without the help of tools.

29th Apr 2012 14:09 BSTGail Spann Manager

Nice to see some of my dear friends posting on here again!

29th Apr 2012 16:44 BSTBob Jackson Expert

Can't resist chiming in when the subject is quartz. Old photo, before I had a clue how to do this. 6 inch matrix of amethyst scepters, one inch 'iron rose' hematite, Denny Mt. WA, collected 1981. Would love to know where this piece is today!

Why don't you start a 'Where Is It Now' thread?



29th Apr 2012 18:21 BSTPaul Brandes Manager

Hang in there Gail; Nat and I are thinking of you!!!

I'm not sure if I have posted one of these or not, but here is not necessarily a "specimen" but rather more of a mining artifact. Miners in the Keweenaw Peninsula of Upper Michigan while extracting large masses of native copper would cut them up with chisels (by hand) into smaller pieces to make them more manageable to remove. In the process, they would create shavings of native copper. The photo below is an example of one of these shavings or "chisel chips" as they are called locally. The chip measures approx. 8 cm long.

29th Apr 2012 23:36 BSTGail Spann Manager

Nice Paul, I hadn't know that. And thanks for being good friends.

3rd May 2012 00:25 BSTColleen Thomson Expert

ooh Quartz!

Great Amethyst Gail!

i'm a bit of a sucker for Quartz, especially associated with other species. i find them endlessly fascinating.

Here's a nice classic miniature ( about 6 cms high) of quartz with hematite 'roses' from Switzerland

3rd May 2012 04:00 BSTBrent Lockhart

Nice Hematite Colleen, love to see the classic Swiss association pieces!

3rd May 2012 08:55 BSTPhilip Perkins

Fantastic Rhodochrosite specimen Gail, great acquisition.

My favourite for today, a bouquet of mini quartz scepters from a Dugway geode.


Dugway Geode Beds, Dugway Pass Area, Juab Co., Utah, USA

including base 3.0cm x 2.5cm

18th May 2012 07:47 BSTAM Mizunaka Expert

Today's favorite is a tiny twinned rutile crystal from North Carolina. 9.6 x 15.4 mm.

18th May 2012 18:43 BSTValere Berlage

Hi to all

Here is today a link to a rock I managed to bring into my collection after it was already sold!

These are among my favorite rocks in the mineral world, period! A few old (1920's) and a large suite of the new (2011) speciments are the backbone of my collection, and I am ready to big sacrifices to go further that way! These are too scarce and too unknown to be classics...

This speciment is small, not cheap, but I like these too much!


25th May 2012 18:56 BSTStephen Rose Expert

I have always liked the bright luster on these crystals; many of the Glove specimens have a matte finish. My favorite today.

Wulfenite, Glove mine, Amado, Santa Cruz Co., Arizona. 6.5x5x2.5 cm.



26th May 2012 02:08 BSTSamuel Knipmeyer


Neat sample!

26th May 2012 14:01 BSTSteve Sorrell Expert

I haven't posted one for a while so thought I'd post this one, painted tonight...

Columbian emerald in matrix...



26th May 2012 23:46 BSTStephen Rose Expert

And today a small legrandite from Mina Ojuela, Mapimi, Durango, Mexico. The crystal cluster is about 1x1 cm. Some specimens with this lot had wonderful koettigite/legrandite combinations.



28th May 2012 20:52 BSTColleen Thomson Expert

wow - great painting, Steve - love the ones on the black background :-)

i went to the Oxford show the other week and spent far too much pocket money :-D

heres one of my acquisitions. From an old french collection, a thumbnail of a Quartz crystal with several large lustrous brown Anatase crystals attached (to 12mm) from La Lauzière massif, Savoie, Rhône-Alpes, France

29th May 2012 03:19 BSTDanny Jones Expert

Bunker Hill Properties, Kellogg, Coeur d'Alene District, Shoshone Co., Idaho, USA

Three nice clean spheres of orange pyromorphite. Purchased in Tucson Feburary 2002. Always one of my favorites.

9th Jun 2012 07:11 BSTAM Mizunaka Expert

Azurite pseudomorph after calcite with cuprian adamite from Greece. 4.5 x 4.1 cm.

The opposite side of the specimen.

9th Jun 2012 07:33 BSTRock Currier Expert


Thats a great shot and a fine specimen. I have placed it in the Best Minerals Pseudomorphs and Azurite articles. I would steal more from these forums, but frequently they are not uploaded to our gallery which is one of the requirements that we have for use in these articles.

9th Jun 2012 15:08 BSTRyan L. Bowling

That's a really cool piece AM, inspired me to post something new today!

It has been sometime, so here is compilation photo.

Here are a couple Brazilian Classics, Jonas Tourmaline and an etched Aquamarine. The tourmaline is 5cm, the aqua is almost 4cm.

BTW, be sure to check out Wendell's article on the Jonas Mine in Mineralogical Record, nicely done.

9th Jun 2012 22:06 BSTPhilip Perkins

AM i also love your Azurite, great piece.

Ryan just love your Jonas Tourmaline, when you tire of looking at it, you know who to contact..

11th Jun 2012 00:21 BSTStephen Rose Expert

My favorite today, even with the imperfection.

A fine, clear, iron-oxide stained fluorite measuring 2.8x2.5 cm on a matrix of fluorite crystals and a rubble of baryte and fluorite fragments. The unfortunate 'ding' on the primary crystal is due to overzealous use of my water gun. Overall size: 9x7x5 cm. Collected in (about) 2000.

Boulder Hill mine, Wellington District, Douglass Co., Nevada

AM, what an intriguing specimen!



11th Jun 2012 19:41 BSTLinda Smith

My favorite for today. Ruizite with Kinoite micro from the Christmas Mine, Gila Co., Arizona.

AM, great pseudo!

15th Jun 2012 23:51 BSTJoan Kureczka

Definitely my favorite of the day. Just dug today in fact.

20th Jun 2012 21:43 BSTLuiz Alberto Dias Menezes, Fo.

Ryan, do you have a locality for your etched aquamarine crystal?; it looks to me that is from Jaquetô, Bahia (from a great pocket found in 1990)

21st Jun 2012 01:48 BSTDanny Jones Expert

Barite with hemitite coating. Something very different but one of my favorites

21st Jun 2012 04:26 BSTRyan L. Bowling


It is from Jaqueto, from the great pocket. The color is much deeper, more like Medina, my photo does not do justice to the aqua color. It is from an old collection.

Malachite after azurite with smaller azurite, cerussite, and malachite after azurite crystals scattered around the matrix. Tsumeb. 6.5 x 4.2 cm.

23rd Jun 2012 14:41 BSTSteve Sorrell Expert

Very nice AM!

It takes a while to sort through stuff. This is a very aesthetic little thumbnail specimen that I picked up at Tucson this year. I only got to look at it properly tonight. Never enough time!



25th Jun 2012 19:44 BSTStephen Rose Expert

My favorite today.....

In the 1970’s the California mine was still open to collectors willing to muck out the rock piled up at the portal. The veins containing good specimens of beryl, molybdenite, ferimolybdite and a variety of other minerals were reasonably accessable in open stopes. Some decent specimens were also found on the slopes above the mine where the vein system outcropped in the talus. Large crystals of beryl were rare although there were reports of well-formed goshenite crystals of several inches in size.

This beryl (var. goshenite) specimen was collected in 1975. The crystal is a simple hexagonal prism terminated by first and second order dipyrimids. It measures 2.2x0.7x0.5 cm. California mine, upper Browns Creek drainage, Nathrop, Chaffee County, Colorado.



5th Jul 2012 00:37 BSTGail Spann Manager

Just picked this Kongsberg Silver, with acanthite, up this week. Haven't catalogued it yet, miniature.

5th Jul 2012 00:49 BSTGail Spann Manager

5.3 cm tall by 3 by 3 cm.

largest crystal 16 by 10 by 10 mm.

Apophyllite, pink.

Samson mine, St. Andreasberg, Harz mountains, lower Saxony, Germany.

Collected prior to 1852.

5th Jul 2012 06:53 BSTAlexander Carrington

Thanks for sharing Gail,

It's fun to see new additions in your collection. Here is my favorite for the day, and favorite forever. It is a Gwindel Quartz with Chlorite from from Val Strem in Switzerland. It has great twist and it is a clear quartz gwindel, which is in fact much rarer than the smoky gwindels. The bottom side of the specimen is fully crystallized; it became detached from mother rock during a late growth period and fully re-crystllized again.

It is 9.1 cm tall and 6.0 cm wide.

5th Jul 2012 20:36 BSTJohn M Stolz Expert

Thought I'd poke my head out from all this lurking about and compliment you guys on the beautiful specimens. Special acknowledgement to Steve S for that mouthwatering wulfenite... I really need to take some pictures...

Regards, John

7th Jul 2012 09:42 BSTSteve Sorrell Expert

Thanks John :)-D

Here's a nice blue barite from Rochester, Victoria...



7th Jul 2012 18:52 BSTJohn M Stolz Expert

Wow, you could get lost in all that blue, Steve...

So technically this Sunnyside Mine Rhodo is not my favorite--I havn't even held it yet, but it could be my favorite. This is the dealer's photo. It's off getting a major trimming right now...

Those are little clear fluorites up top.


8th Jul 2012 03:45 BSTGail Spann Manager

John, it's fabulous, can't wait to see it after a trim.

8th Jul 2012 10:00 BSTAM Mizunaka Expert

Today's favorite is a glassy lustrous amblygonite crystal from Brazil. 3.8 x 2.7 x 1.1 cm.

9th Jul 2012 05:11 BSTBob Griffis Expert

This is a neat piece with quite an interesting history...

Schorl, Apatite, Quartz

Woolley Farm, Bovey Tracey, North-Eastern Dartmoor, Dartmoor & Teign Valley District, Devon, England, UK

81 x 80 x 40 overall. A well formed tabular Schorl crystal measuring 31 x 22 mm is prominently perched on tapered, slightly frosted, smoky Quartz crystals to 48 x 11 mm. This Schorl is doubly terminated, lustrous on the pyramidal and prism faces, and etched on the other termination, as typical from this locality. A Quartz crystal partly pierces the Schorl, showing that the Quartz formed first. Pale yellow, barrel-shaped Apatites to 11 x 10 mm are also perched on the Quartz. Other complete and partly complete Schorls are present. Some of the Quartz points are missing, but the large Schorl and the Apatites are pristine.

This specimen was formerly in the collection of Robert Ferguson (1767-1840) of Kirkaldy, Scotland. In about 1997, the Ferguson family sold the collection to Brian Lloyd, a well known London dealer, and this piece was purchased in about 2000 by Shields Flynn of Trafford/Flynn Minerals of Norfolk, MA.

I agree John, some breathtaking minerals and photos, I was mesmerized by AM's azurite, but they are all really great!

I was going through some Norway specimens and decided to give a little spotlight to this piece. It is really just a reference sample (most of mine are!) but I wanted to give the plain minerals a little love too! Also the name Lizardite is rather catchy.

Hello all,

Long time since I have posted.

Here's a hematite from Morocco about 9 by 6 by 5 cm.

Good luck!


15th Jul 2012 04:50 BSTPaul Brandes Manager

Plain minerals do need love, Stephanie!! Some folks may consider crazy lace agate to be plain as compared to the exquisite gems seen in this thread, but for today the colours of this specimen just popped out at me and begged to be noticed. The specimen measures 6 cm x 4 cm and was given to me by a collector of Mexican and Southwestern US agates.

15th Jul 2012 06:54 BSTStephanie Martin

Paul, crazy lace agate may be abundant and deemed ordinary, but the patterns and colours are no less extra-ordinary. Lovely piece.

Jelmer, those lustrous hematite bubbles are just beautiful too!

Here's a piece that I found at a local rock shop where the owner imports most of his stock from Brazil. It seemed unusual so I decided to adopt it. It is not a gemmy piece so that makes it ordinary, but I think it has character and so it is my favourite today.

Azurite is one of those minerals that has a wonderful range of habits. These radial azurite "suns" with some malachite accents are one of my favourites.

I know.

I should be ashamed of myself.

AND on a public forum to boot.

But Steph, I don't think I've ever seen anything uglier than that ole spodumene with that crummy dendritic staining, in my entire life.

There; I said it.

Here I am, staring at this thing, and I like you and all, and want to encourage you and you do this. I waste--waste I tell you, 5 minutes looking at that piece of crap trying to come up with something positive. Meanwhile, I'm thinking, I'd really prefer to be looking at that gorgeous agate, or AM's Fluorite; but no, I have to look at this ugly ole rock. It's like, massive, and..., and..., and you didn't even hose the dirt off before shooting a picture of it!

And the funny thing is I know you have so much (by the way, where the heck do you store it all?) nice stuff--why can't you just show some of that? You test my ability to play nicely in the forum. And you know--that's it! You made me write all this; you probably thought--hmm, how can I mess with the guys on the Best of... forum? I know, I'll go get this piece of crap from under the garbage cans, and say I spent good money because of it's "character" and see what happens. I'm going to bet that Alfredo thinks it's the most beautiful thing he's ever seen, and see if anyone tips over the edge with this monstrosity.

Well, I suppose I should wind this little diatribe down. God help me if we ever meet, you'll probably shoot me. And I probably deserve it.

Regards, John

20th Jul 2012 04:36 BSTStephanie Martin

Golly John, I am touched that you feel that way. Really. If I take anything away from your message, it is that I should start an Ugly Minerals Thread so that there can be more disturbing and deplorable photos of minerals of which you are unable to take your eyes off.

I for one can't take my eye's off AM's fluorite, it gives an ethereal glow off the computer screen. A true Spanish beauty and spectacular photo.

And Denny, lovely matrix piece as well.

John, no worries if we should meet, I won't hold the ugly rock against you, I wouldn't want to rub off the precious manganese oxides.

Oh, and I store my minerals in ugly drawers too.:-D

Here's another despicable photo in a compromising pose. Bet you can't stop looking at the tack. LOL.

John & Stephanie get my votes for best message & response in, like, forever. Stephanie, that picture is worth a thousand words! Did you buy that specimen just for its expressive nature, holding it in reserve for a moment like this? (Hats off!)

Ugliest Minerals could be an entertaining thread, for sure. My wife thinks I'd be a frequent contributor. (My search for new native copper localities had led me to more than a few samples of buttuglyite, for sure.) Might get some submissions of ex-helvite sludge, based on other ongoing threads...

I think the dendritic Mn oxides on Stephanie's spodumene are interesting, and deserve an analysis to see what species they are. :-)

20th Jul 2012 16:55 BSTDean Allum Expert


I don't usually read this worthless thread, but was curious why Alfredo would post here.

It is interesting to contemplate what drives the magnesium to form these interesting dendrites. I collect similar spodumenes. They have a much deeper red light transmission than their surface color would indicate.

Please add your lizardite pic to the Buskerud gallery to let collectors know what they can find there.

They are those "Interesting But Ugly" ones that people like us love because of form, color, wierdness or what ever that just strike our fancy. It takes a special breed of crazy fanatics who love all things interesting to appreciate their beauty.

Always glad to see the interesting posts on this thread.

20th Jul 2012 21:08 BSTJohn M Stolz Expert

@Allen, Jeez tell us what you really think why don't you! People have feelings you know. They don't like to take the time and post their specimens and then you come along and say the thread is worthless.

@Alfredo, yeah, but isn't it the most beautiful thing you've ever seen?

@Donald, thanks for defending me--I think!

@Steph, you took it like a trooper, just like I knew you would. But I know you wouldn't worry one whit about those dendrites if that rock was in your hand when you met me...

21st Jul 2012 09:58 BSTPhilip Perkins

Stephanie keep posting your specimens, it makes no difference to me if your specimens are ugly or those you don't post, because they are worth thousands, LOL

I love your Chalcedony & Stilbite specimen, very nice.

Two years ago i had requests from 2 collectors requesting details as to how i custom mounted my specimens on acrylic bases.

the first guy was a delightful young man from Seattle, he was very much apprecative for my help & thankful..

The second guy from California demanded that i hurry up & give him the detaills, he needed to mount his specimen NOW!

after spending quite a bit of my time setting out all the steps in the proceedure, he didn't even have the manners to show his gratitude

& say thank you.

The moral of this story.....the young collector could teach this older guy some manners.

21st Jul 2012 20:28 BSTStephanie Martin

Thanks Philip, I am undeterred. John is correct that I do mess with you guys, although I never really tried to hide that fact. All in good fun.

Ironically that lowly dendritic spodumene has generated enough feedback that I am going to start 2 new threads in the near future. There will be one for dendrites and one for IBUs. So stay tuned, there is definitely more to follow! John, you don't have to watch!!!

In the meantime... back to minerals!

Rock man456, that is a terrific flourite. I would like to see you take a picture of it by itself on a plain white or black background, so it can get all the attention it deserves.

While we are on fluorite here's my favourite for today. Why is it my favourite? The green is electric in person. And while this isn't a museum piece, it only set me back $5. And there appear to be some type of manganese or iron oxides to boot!

Always enjoy this forum, I appreciate so much all the folks who post such wonderful eye-candy, and the playful ribbing over the beauty-contest losers. Today's favorite is a calcite from Ojuela Mine, Mapimi, Mexico. Once in awhile auction specimens surprise me with how nice they are, and this was one of those pleasant surprises.


23rd Jul 2012 06:45 BSTStephanie Martin

Bob, by gosh I think you are right! Good idea!

Michael - gorgeous specimens. Just in the nick of time.

Wynne, definitely agree that those auctions can come up better than expected. It's always a pleasant surprise when it does. Thanks for sharing your prize.

John - I am not sure why the string chalcedony forms like that compared to the other types that come from there but I have often wondered that myself. I have never seen them in situ but I am assuming they must come from similar geode type environs as the others. I have a variety of these in the blue-grey and white strings, as well as in geodes and just plain globular type formations. I also have some mordenite ropes with heulandite that look really peculiar and which I think they are likely chalcedony under it all. In any case they are a novelty and I do enjoy them. I just wish my camera captured the pale colours better.

Don't look now - is it a bird, a plane or flying fish? Not sure except that whatever it is looked like it crashed and burned. I'm going to call it "Stil-Air".

Well John I never stopped to count my vessels as it has not been a conscious effort. But here's a blimpy looking apophyllite, or perhaps it is a sub with a large periscope sonar thing. Or a beer tap. You decide. LOL.

Stephanie I really like the airplane? or whatever. I also like the idea of an IBU thread. So many people are so concerned with the absolute flawless perfect specimen that they overlook the odd interesting pieces that only a mother would love. I am always amazed at the form some minerals take even if they are not the most beautiful. I will have to gather some of my IBU. Unfortunately I have gotten so busy lately I haven't had enough time to participate in the mindat discussions as often as i would like but I will look for your IBU thread as well as the dendritic thread. Dendrites can be amazing as well.

Definitely my favorite of the month, even if I never get to see it "live". Weighs about 300kg, so was a chore to retrieve.

25th Jul 2012 22:30 BSTStephen Rose Expert


Wonderful, rich color on your N. Vernon specimen. Great locality!

A plate of translucent fluorite crystals on matrix from the Rogerley Mine is today's favorite. 10.6 x 8.6 cm.

2nd Aug 2012 21:01 BSTRob Woodside Manager

Killer piece but that is transparent and not just translucent;-)

3rd Aug 2012 22:01 BSTPhilip Perkins

Great Wulfenite Michael,

here is another, size 65mm..

5th Aug 2012 06:11 BSTStephanie Martin

Awesome photos!

After reading Tomek's Madagascar report I was reminded again of what it takes to get a specimen from source to here, and I appreciate each piece more for the trek it has to take.

My favourite today is this violet spinel on marble.

Double-stemmed amethyst-sceptered smoky quartz from the Boulder Batholith, Jefferson Co., Montana, USA. Collected this May, it's my favorite today, because it's leaving my custody after finally splitting up the find with my collecting partner.

Because the Boulder Batholith has enjoyed long periods of deformation (as the structural geologists say), it originally came out of the pocket in 2 major and 5 minor pieces. Fortunately, we were able to piece it back together. Approximately 10x12 cm.

11th Aug 2012 22:37 BSTRock Currier Expert


Would you consider uploading the image to the Mindat image bank? If you don't know how to do that, I can provide instructions.

11th Aug 2012 23:44 BSTJonathan Woolley


Absolutely! Will do right away. It's listed under the Delmoe Lake area.

12th Aug 2012 10:39 BSTRock Currier Expert


I have placed the image of your specimen in the Best Minerals article on Quartz, USA, Colorado to Montana. What can you tell us about the locality and the quartz specimens it produces to go along with the picture?

12th Aug 2012 13:45 BSTJason Evans

My favourite of the day, well its been my favourite since i got it a few days ago, is my Iris quartz, I am entranced by the beautiful flashes of rainbow colours and the fact that it is natural makes it awesome. It is s a shame that it is mostly new age stores that sell this as anandalite, I suspect a lot of mineral collectors stay clear of those kinds of stores so a lot of people may not have even heard of Iris quartz, or might think its just another angel aurora type quartz. The colours were hard to show on the photo of the entire specimen so i took some close ups of the crystals.

It is from India but the exact location is unknown, the seller said it was from Maharashtra, but when i uploaded it, it said the location was not listed in the database, so I instead labelled it as being from Madhya Pradesh as that seems to be the only accepted locality for it.

Hardly an hour goes by before i get the urge to pick it up and move it around under the light so i can see those rainbow flashes!

12th Aug 2012 16:45 BSTStephanie Martin

Jason - I have about half a dozen of these quartz from different sources and all list Aurangabad as the location, so I was wondering if there was more than one location too. I was thinking of sending queries to the dealers to see if they know more, but it may be one of those situations where the true location is being mistold to safeguard the find.

My favourite today is this specimen from the Thomas Range, a location that provides many interesting minerals and assemblages.

From Jeremy Fuller.

Nice piece Michael. I aspire to get one of those some day...

Steph, wow that looks kind of like my vanadinite... but *cough* shouldn't you be posting that beauty somewhere else?

Jason, I like those irridescences--reminds me of the piece below--although yours has far more spectral range...

15th Aug 2012 10:01 BSTValere Berlage

A giant M'fouti Wulfenite crystal, belonging to the Musée Royal d'Afrique Centrale, Tervuren, Belgium! Currently not on display, that speciment impressed me when I was a kid, easy to understand why! My hand for the scale...

Hi Tony,

I am glad that you got one of our famous Topaz from Argentina!

This piece was the only good one on matrix. In general, came out only about 25 pieces!

The location can now be considered "mined out". One of our group was there again and nothing more has been found!


Robert Brandstetter

17th Aug 2012 02:35 BSTJonathan Woolley

Amazing wulfenite, Valere! Nice malachite formations on your Morenci specimen, Michael.

My favorite today - another Montana piece collected this May. Calcite from Gallatin County. 15.5 x 10 cm.

17th Aug 2012 04:23 BSTStephanie Martin

Woo Hoo! That is a whopper of a wulfie, Valere. Thanks for sharing that one.

Enjoying everyone's posts - Jonathan those are delicious self serve pieces. Really nice finds.

Here's my favourite for today. Sorry the location is not fully certain. These seem to be attributed to Chenzou Province, China, but this one has a baryte assocation that makes me wonder. Also most I've seen list the sulfide as pyrite, this one was indicated as chalcopyrite. In addition to the preferential edging I really find the little pyramids poking up through the coating rather endearing. It is a busy specimen and the more I look it over the more I find!

Calcite, Chalcopyrite, Baryte

Chenzou Province, China

Ooops, John... Do I hear you coughing again? BTW you should really get that checked. Could be a serious case of rock jaw.

4th Sep 2012 06:06 BSTStephanie Martin

My favourite today is this green quartz from Inner Mongolia. While I am not sure what is responsible for the green colour (possibly actinolite), this one caught my interest because it came with what was noted as specularite at the base of the main crystal along with some calcite accents.

To absent memory...still bright.

8th Oct 2012 16:27 BSTPhilip Perkins

Thanks Steven for your comments, i have 3 other Bulgarian Galena's that i think are special,

one has hopper shaped crystals, another that has superb octahedral spinel twinning & the one

that i'm posting now with cubic spinel twinning.

As you enjoyed the other specimen i will try & post the others too over the next 2 days.

Thank you mister Menedez for the correct locality of my Brazilianite.

Today I offer you a bit of a curiosity. Not uncommon material but from a newly discovered locality in the Netherlands!

I sincerely hope this is a one-time find and that production will stop soon.

These little rocks (the biggest one is about 2 millimeter) were fabricated by my right kidney. I am still recovering from the agony that was caused by the delivery process.

Does anyone know the chemical structure or minerals involved?

Great favourites one and all! Neal, you've been practising and it shows!

Gail, that is a wonderful work of art in itself. You have been "assigned" :-)

AM - a stunning photo regarding those Spanish cubes, a superb result bar none.

I think it is about time to post something Moroccan...

A little chunk of fluorite ~nothing spectacular like those previously shown, but I like it for the interesting features of the hint of banding and pyrite/marcasite? inclusions.

Today's favourite is an aquamarine (15x8x7cm) from muiane pegmatite, mozambique.

25th Oct 2012 04:43 BSTStephanie Martin

Hi Joo,

Mozambique certainly has some nice pegmatite minerals. Great first post!

I'll be doing the Moroccan theme for a few posts... hope you all don't mind.

Vesuvianite is one of my favourite minerals, so today it is fitting to show a vesuvianite in matrix from Imilchil. Normally you just see floaters.

Gail and Stephanie - thanks for your encouragement.

Today's favourite is a calcite from Romania which has been sitting quietly on the shelf for some years... I call it "ugly duckling". Dimension about 12x 9x 6cm.

25th Oct 2012 15:53 BSTGail Spann Manager

Goodness Joo, that's quite a calcite!

25th Oct 2012 16:02 BSTMatt Wall

Thanks for sharing,

Kind regards,

25th Oct 2012 17:57 BSTPaul Siegel


As a long time collector of Romanian minerals I can tell you that your "ugly duckling" is an outstanding specimen. Is it from Herja? I would be proud to have a specimen like that in my cabinet.



25th Oct 2012 19:25 BSTStephanie Martin

Joo, I agree it is not an ugly ducking but a beautiful black swan... (or possibly a strange alien or bug eyes lol), definitely a commanding piece.

If you want to post the pictures directly into the thread it is easy, you just put the cursor where you want the picture to go, then click on the button beside your photo upload that says "create link in message" and your picture will appear rather than just the link.

26th Oct 2012 05:50 BSTStephanie Martin

Today my favourite is this single little Wendy...

The label does indicate Wendwilsonite, however I am unsure if this was analysed, so in theory it could be roselite-wendwilsonite series.

This is just a little micro sample but the photos turned out better than some of the clusters I have because it has one nice isolated single crystal that posed nicely for the camera, and revealed some of its pleochroic attributes for me in the process too.


Aghbar Mine (Arhbar Mine), Aghbar, Bou Azer District (Bou Azzer District), Tazenakht, Ouarzazate Province, Souss-Massa-Draâ Region, Morocco

Hi Stephanie. your photography is fantastic, if any of us amature photographers need advise, are you willing to give it? lol

Absolutely love your Wendwilsonite, it is so gemmy, you have done so well capturing it's true gemminess, on such a small specimen.

1st prize for Stephanie

27th Oct 2012 08:12 BSTStephanie Martin

Hi Philip,

Thanks for the kind words, but you really should not encourage me like that, you rascal ;-). I'll just have to post more photos to prove that I am still a rank amateur lol. It helps to have a photogenic subject and some minerals are definitely more cooperative than others. I still have a hard time with grey, light blue and pale pink shades. I have yet to be satisfied with any celestite I have tried.

With your support I decided to revisit a specimen that eluded a satisfactory result a couple years ago when I first was learning digital photography on top of learning how to do minerals. Seems I have improved a bit since then, so here are some views.

Titanite, Epidote, Quartz

I hope I'll be back one day when I have ramped up my photography to a point where I won't be ashamed to show it. In the meantime, I'll just have to enjoy my favourites by eye and try to send the images telepathically!

I use my trusty Nikon and do the best I can without proper lights and what not. It's about what captures your glowing attention that we care about. It can be pieces from museums, or friend's pieces, or something you would love to own.

It's about FUN. us your favs!!!!!!

Stephanie, that pierced vanadite is really quite something.

This piece never ceases to catch my eye and usually causes an "approving or interested comment", even from a non-mineral person.

Gail, is that a Wessels mine Hematite ?

29th Oct 2012 14:25 GMTLarry Maltby Expert

I recently picked up an old copper specimen labeled "Houghton County, Michigan" and noticed this nice calcite. (10.6 mm)

It looks as if it is being held up by two copper hands. I hope they don't drop it!


29th Oct 2012 16:51 GMTTimothy Greenland

OK Gail

Them's fightin words! I'll try to take up the challenge. This one is an all time favourite not because of the rarity - it's only calcite with a bit of fluorite, but there is a story with it.

On Saturday the 25th of may 1962, a much younger T.G. took off from his student residence in Manchester (England, England) with my friend and mineralogical mentor RSW Braithwaite, to meet up with two other notable mineralogists for a weekend's prospecting. On our way to the meeting place we stopped by at Treak Cliff, Derbyshite - the home of 'Blue John' fluorite. After wandering around the hillside and finding only tiny veinlets of blue John, I took to tapping the exposures idly - and a bit boredly with my hammer. Intriguingly one patch rang hollow, so I belted it one... A hole appeared leading to a ca 2 ft vug lined with bobbly fluorite with a purple cubic surface and typical fibrous 'Blue John' structure below. In the vug there were a few white scalenohedral calcites peeking through the fluorite, looking indeed just like dogs' teeth - and one single large, fairly clear curved scalenohedron which came off with a rosette of blue John at its base - best of all, if you look closely, it's a twin with a cleft visible just above the blue yellow (bleu-jaune = 'blue John') rosette. It remains one of my very favourite finds.

I'll cheat and attach two pics, 'cos the B-J doesn't come out too clearly on the first.

Today I like this piece, a 4.5 cm gem xtl of yellow sphalerite from Huanggang. It's probably the best piece from that early 2012 pocket mentioned in the MinRec. Amazing for China, though not quite to the level of Spain....

29th Oct 2012 17:56 GMTNeal Luppescu

Since Gail is on a hematite binge, I'll add my two cents.

This one has epitaxial rutile, and is from Cavradi Gorge in switzerland.

4 cm in width.

Thanks to all for the kind words and Debbie Woolf for helping to insert the pictures.

Today I'd like to share a double terminated quartz engulfing reddish tourmaline from Antsikoza, Madagascar. I got two specimens 2 or 3 years ago and have not seen more.

Not sure if anyone is familiar with this find? If only the quartz could get clearer!

Nice one Neal!

Great to see everyone posting. Stephanie, you have added so much to this thread, thank you.

30th Oct 2012 05:44 GMTStephanie Martin

Gail, thanks for the support. I try to have fun with this thread and enjoy everyone's precious pets in the process.

David, glad you liked the spiked vanadinite. There are actually a few more that are jabbed but the point doesn't break through.

I have always been partial to those etched Brazilian spessartines. I can't decide if it reminds me more of a printed circuit or an Escher drawing. Either way you can get lost in those!

Timothy, I am a big fan of your fanned Blue John, really a sweet find and no doubt more than just a great memento. Nice to see your first favourites post!

Joo, I've seen a lot of unusual inclusions in Madagascan quartz but pink tourmaline is not something that comes to mind. But then, Madagascar is full of surprises.

My favourite today is going to be a little different because it's actually a fossil. Morocco is known for fossils and unfortunately fake ones too, but I can assure you this one is real. And just to keep with the mineral content, the matrix is limonite, lol. Not the most beautiful species, but I tried to make it face the camera so at least it's smiling at you! Children love playing peek a boo with these, and I must confess, so do I.

A flat hematite plate from Sicily is today's favorite. 4.9 x 2.0 cm.

30th Oct 2012 09:12 GMTTimothy Greenland

Thank you both, Philip and Stephanie, you are very kind, and yes, that specimen is really special to me. An interesting extra is that the fluorite from that vug shows a thin band nerar the start of the deeper purple surface that fluoresces weakly red in both LW and SW U/V. Most unusual for Derbyshire fluorites...

Just before I finish stuffing things into my backpack for Morocco, I can't resist another try.

This one is another self-collected favourite - most of my real favourites are self-collected for the memories that come with them - I am very fond of a lot of 'bits' that I have exchanged or bought, but they don't quite have the same emotional impact...

An expedition to Ecton in Staffroshire in October 1962 along the Clayton adit towards the Waterbank mine workings yielded some rather good specimens of aurichalcite (analysed) and here is my best one - not Mexican standard, but well... Its a real problem to photograph - always looks fuzzy. I need a really solid camera support, I suppose. Anyway it gives the general idea - the maximum length of the specimen is 6 cms.

Hope you like it!

Wish you were comng to Morocco too Gail, still it'll surely be fun even without you!

Over the years you have posted images of many good specimens that I would like to use in the Best Minerals articles but don't want to until the copyright issues are made clear and I can pull them from our general gallery. Compared to the amount of time it takes to take the images you attach to your emails the amount of extra time is perhaps only a minute once you get the hang of it. Once they are in the mindat gallery you will be surprised how useful they are there and how easy it is to access them and how many people look at them. I am constantly getting requests to use the images I have uploaded, either of the specimens or the localities I have visited in search of specimens. Also if any of your specimens are stolen or lost because of fire etc, It is easy to search them out on Mindat.

Just find the locality page for the specimen and click on photos and then Add Photo. Then just fill out the form and click the button at the bottom. Since you are a manager the image will instantly be placed in the general gallery. Its easy piezy! Cummon! its easy. You can do it.

From Madagascar, a beautiful Chromium Beryl.

1st Nov 2012 05:25 GMTStephanie Martin

Awesome photos!

Yesterday I decided to have a look at this specimen and see if it was up to the task of being a favourite. Most everyone must have one of these by now as they are readily available and standard fare. I took a few photos but wasn't really happy with the results as the flaws seemed to outweigh the good points and given it's common it needed a bit more pizazz. But I decided to try again and take some close ups of the larger crystal. When I moved the specimen around to get different angles for the main cerussite I discovered that some of the smaller crystals near it were coated with a bright yellow metallic lustre not evident from every view. This surprised me as I didn't notice it until I reviewed the photos because at first glance they do not appear metallic at all. You never know what turns up when you review the shots. So based on that, it's now become my favourite of the day!

I just love coming here every few days and seeing what everyone is posting. You guys really have some nice stuff. Although my wife thinks I have too many specimens, they actually number under a couple hundred, so it's been pretty easy to burn through them all showing them off. But you guys must have thousands of pieces--where on earth do you display them? Or are they put in drawers and pulled out one by one for examnation? (Gail, I've seen enough PR photos of your collection to know you've got a veritable museum in your home--but I for one don't have that kind of space!)

Now Steph, I was going to chide you for misposting that fossil specimen until I realized what I was really looking at. I am actually looking at a nodule that splits open to expose the tribolite, correct? How on earth was that accomplished--and how did anyone figure that there was a specimen buried in there in the first place? It'd be great if you could throw a couple of paragraphs together on that for those similarly interested.

2nd Nov 2012 00:36 GMTThomas Spann

I have lurked on Gail's thread for too long...time to post my favorite of the day.

This fluorite with calcite specimen from Yaogangxian is the piece that inspired my wife, Melissa, and I to collect miniatures. This is an "old" photo that I took before really knowing what I was doing regarding mineral photography.

2nd Nov 2012 03:38 GMTStephanie Martin

Tom, a fabulous miniature and no wonder it enticed you into that realm. Since this is one of your earlier photos I would say that you are a natural. Wonder where you get your artistic gift from?

John, I have a few of these trilobite nodules and most have several test areas where it appears opening was attempted prior to succeeding. I am sure there is a bit of intuition and a knack that would come with a lot of practice, but like a box of chocolates, you could never be sure of what's inside ;-) The one I posted is a rather complete one with a nice flat presentation, they are not always so complete or oriented as well. Still I find them intriguing that they can do this at all. I am sure there are a lot of casualities in the process. If you like nodules with surprises, then the Mazon Creek, Illinois nodules have an interesting variety of creatures and botanicals found in them, many unusual ones such as soft bodied jellyfish and sea cucumbers that would normally not be preserved. Great little time capsules indeed and fun as well. Now you see it, now you don't...

Wish I was in Morocco soaking up the sun :-(

To cheer me up, this is my favourite today. Not quite a sun, but a radial spray...

2nd Nov 2012 13:40 GMTBob Harman

From my Ohio minerals sub collection, this Clay Center Quarry CELESTITE on DOLOSTONE matrix measures about 20 cm in maximal dimension. The vast number of bladed Celestites from this locality are overcrowded and have nibbled tips while this specimen has several 5cm to 7cm sprays and the tips of the blades are largely intact. As it is a fragile specimen, I prefer not to move it around, hence it was photographed in position on my shelf. No Fluorite accompanied this specimen. CHEERS...........BOB

3rd Nov 2012 06:44 GMTStephanie Martin

Hi Philip ~

That's a smoldering smoky from Queensland! Thanks for the note on the cerrusite mix, I too thought it looked like chalcopyrite, but when you turn the crystals to change the lighting angle, they are transparent, so not chalco.

Bob, I am always amazed by your posts. Those celestines are sublime.

This specimen made me fall in love with azurite, so it's definitely a favourite. It is the deepest coat of indigo blue I have ever seen, moreover the micro druse sparkles all over like sugar, twinkling like the night sky. Sadly my camera was not able to get the true depth of colour as it appears more violet in hand than the photo shows. A cherished piece from Frank Melanson.

Speaking of lucky openings of hidden cavities, this pocket of fluorapatites from Harvard Q. in Greenwood, Maine, was opened via a diamond saw cut. Clearly at least one crystal was cut into, but many nice ones are preserved. Without the saw cut, this rock probably would have gone into the "road fill" pile.

This one has a beautiful blue termination, which I didn't expect until I look at it against a light source.

Locality is only known to be Minas Gerais. My guess is pederneira, sapo, or santa rosa. Would appreciate any suggestion on which mine this could be from. Thanks!

Two images - Photo ID 258592 and ID 302068 are accredited as having originated from Slip China Stone Quarry, St. Dennis, St. Austell District, Cornwall, England, UK. Slip Quarry lies in the heart of the relatively small non-megacrystic lithium-mica granite portion of the St. Austell Granite Mass where no megacrysts exist. It was worked for China Stone for use in the ceramics industry. The two kaolin peudomorphs after orthoclase came from either the western lobe of the St. Austell Granite Mass (which embraces the Melbur China Clay Pit, a common source of these specimens in recent years), or the eastern part of the Mass, from such historic sites as Higher Ninestones or Great Wheal Prosper China Clay Pit.

I suggest that the location caption be amended to St. Austell District, Cornwall, England, UK, thereby embracing all possible megacrystic sources.

Hi all,

Gail, the Crocoite is a stunner, nice to see a little bit of Tassie in your collection. I guess you already know but for everyone else, the very very nice Crocoite would be from the Adelaide mine, aaand looks a bit like one of the 2010 mob. If it is, then one had some amazing mates too.

And the 2012 find might just surpass it.......think about walls with orange fur....


13th Nov 2012 22:22 GMTGail Spann Manager

14th Nov 2012 08:17 GMTAndrew Tuma Expert

Some very nice pieces posted here recently. Haven't put anything up in quite awhile myself, so thought I'd contribute this Munich show acquisition. Tourmaline from Sahatany Valley, near Antsirabe, Madagascar. 5 cm tall. This is actually 4-5 intergrown crystals and is quite gemmy, so you can see the different color phases quite well when looking at it in person.

17th Nov 2012 14:55 GMTLuiz Alberto Dias Menezes, Fo.

Joo, do you have any guess about when this specimen was found?

17th Nov 2012 15:34 GMTTimothy Greenland

I can't resist putting up this one - truly today's favourite. Just brought back from Morocco: Vanadinite on Goethite from vein 12 near (not very!) Taouz, El Rachidia prov., Meknès-Tafialet region. I know I could have bought better, but I found this one - and that makes it for me! Oh, how I curse being such a poor photographer! I have taken about 20 snaps and this looks the least bad - but I wanted to share...

We had a wonderful trip and were SO well accompanied. It was GREAT


17th Nov 2012 18:35 GMTJoan Kureczka

Thanks Gail.

Luiz -- I don't know, but a recent find definitely. We were talking to Frederico Pezzotta who was exhibiting some huge crystals. Interestingly, he said that while the big ones his group purchased were undamaged, there were no small ones without. Mine came from another dealer who had a selection of small pieces, and this caught my eye. The large ones are impressive, but so dark on the outer rind that it is very hard to see any colors.


17th Nov 2012 19:38 GMTTomasz Praszkier Manager

Joan and Luiz,

this specimen as well as the big one come from Estatoby pegmatite in Sahatany from the main pocket found in June this year. In Munich book there is mine article about this find. There was about 1000kg gem tourmaline, the biggest crystal had 7kg and many smaller ones. Big ones were characterized by flat termination smaller ones have pyramidal termination.

19th Nov 2012 01:16 GMTJoo Hong

Hi Luiz,

I got the tourmaline through Dan Weinrich and according to him, the previous owner got it in the early 1980's. There is a tiny quartz on one of the side termination, not sure if this association helps?

I've added a top view of the termination.

Actually, I've been secretly waiting for your expert opinion... Thanks in advance!

19th Nov 2012 01:37 GMTJoo Hong

My favourite today is a mint-green aquamarine from Minas Gerais, Brazil.

Like its rough-textured sides and hexagonal pits on the terminations.

19th Nov 2012 02:21 GMTLuiz Alberto Dias Menezes, Fo.

Joo, my guess about the probable locality of the aquamarine is Padre Paraíso, Minas Gerais; with reference to the bicolor tourmaline, Dan Weinrich's information that it was found on the early 1980's rules out Sapo as a possible locality; my guess would be Cruzeiro, but Santa Rosa could also be the origin; I will ask Alvaro Lucio's opinion, he is the biggest expert in Brazilian tourmalines.

The Wutong Princess is from the Wutong Mine, Guanxi Zhuang Autonomous Region of China. It is a large cabinet size Rhodochrosite with some purple fluorite.

22nd Nov 2012 02:51 GMTCraig Mercer

Yummmmy :-)

22nd Nov 2012 03:53 GMTPhilip Perkins

Gail absolutely love your Wutong Princesse, thanks for sharing.

Craig it's great to see that Bathurst is still on the map,

RE the Faden Quartz, i got it from Bert Ottens in Tucson probably 12 years ago, (he often writes on Chinese localities)

Bert had a whole heap of them, the best were at the time from $300 to 400, it was the end of the show & my money was depleted,

All i could afford was the one that i posted for $150, if you feel that this one blows your mind, i could imagine what you would say about those

i couldn't afford.

22nd Nov 2012 04:02 GMTCraig Mercer

Haha, I was talking about your handmade brass stand champ, bloody classy :-)

Gail’s photos of the opening of the spectacular Perot Museum of Nature and Science in Dallas, with its Lyda Hill Gems and Minerals Hall inspired me to rephotograph my “cascade of pyrite cubes” (photo 352910) uploaded 13 Dec 2010. This is the photo that will replace it for now. As you can see, I’m still having trouble with reflections, but this background is better. I’ll keep working on it. The hanging sculpture of pyrite cubes at the entrance to the Gems and Minerals Hall made me think of this specimen. The museum is also beautiful!

20.6 X 16.5 cm.

Joo, Álvaro Lúcio agrees with me, we both think that the more likely locality for your bicolor tourmaline crystal is Cruzeiro mine

Craig, that mini specimen sure looks juicy!! It also seems to be the seedless variety...Thanksgiving Day brings out the food analogies! Looks great.


23rd Nov 2012 03:46 GMTCraig Mercer

23rd Nov 2012 04:09 GMTGeoffrey Small

That's a killer specimen, Craig! I finally got the motivation to photograph some of my collection tonight and found my favorite of the day in the process =P. Calcite with aragonite from the Holbrook Mine in Bisbee.

23rd Nov 2012 04:23 GMTCraig Mercer

Thank you Geoffrey, and ditto, that thing is insane man, a big bopper as well :-) my kind of specimen. Hopefully we will see some more of your goodies soon.

Great specimens everyone.

This is an old favourite, Ferberite, Arsenopyrite, Fluorite at rear & Quartz.

Yaogangxian Mine, Hunan Province, China.

Size 14cm across, the large Ferberite crystal measures 10cm high X 8.5 wide.

24th Nov 2012 02:18 GMTCraig Mercer

Nice Phil, thought I'd join in with a very similar specimen. Location is the same, just a little bigger. I really need to do as you have and take some photo's of the reverse side. It actually has two Ferberite crystals back to back (butterfly style) with some incredible D.T. Quartz crystal punching through them top and bottom. Amazing thing about this piece is that it stands alone unaided.

24th Nov 2012 13:42 GMTGail Spann Manager

Great favorites Bill, Philip and Craig!

I love this big beastie fluorite, from China.

24th Nov 2012 21:44 GMTCraig Mercer

Haha......"big beastie", I love it, I may have to borrow that one off you Gail ;-) And that Fluorite of your is a star as well :-) I found myself actually trying to look past it after a while, your cabinets look amazing.

24th Nov 2012 22:35 GMTNorman King Expert

The “beasties” posted recently made me wonder how big the largest well-formed crystals of azurite are. (Yes, I know my musings are not very specific–they’re just musings.) Of course, my specimen is malachite after azurite, with the main crystal 10.2 cm in length. This was acquired by Peter B. Nalle (#174) in 1941 from Ward’s Natural Science Establishment, and I adopted it about a year and a half ago. It may be about as close as I will come to an azurite this large.

24th Nov 2012 22:37 GMTAM Mizunaka Expert

Today's favorite is fluorite on smoky quartz from France. 6.0 x 4.6 cm.

24th Nov 2012 23:15 GMTVolkmar Stingl

WOW! The pink fluorite is amazing! (as is the photo quality)

I can only provide a poor photo of a nice piece:

Mexican "coconut" geodes are popularly found in collections and occur as several differing types. Found several years ago, a deposit of these "Rock Candy" (tm) geodes were popular at the 2007 - 2009 Tucson show. This example shows innumerable small amethyst sprays and scepters. It measures about 10cm in diameter and was used as part of the Mexican commercial mining venture's 2007 poster as shown here. CHEERS...........BOB

25th Nov 2012 17:24 GMTStephanie Martin

Enjoying everyone's posts. AM - exquisite as always. Bob, those coconuts do have some fine crystalization and overall look better in person than the photos suggest.

My favourite today is this piece of cut and polished dendritic uraninite and schoepite group minerals, more pictures posted on the dendrite thread.

Hi All

Today's favorite is mimetite from Chah mileh abandoned mine Anarak,Iran

I think it is beautiful.


27th Nov 2012 12:55 GMTRock Currier Expert


That is a very nice specimen. Were many similar specimens found? How large it is? Would you consider uploading it to the Mindat gallery?

27th Nov 2012 13:51 GMTfarhad pirirani

Hi Rock

Ok and I'll upload it to Mindat gallery.

A few months ago I went to chah kharboze mine(very dangerous) ,truly the best red wulfenite in there but I could not find a big Sample.

Aegirine on feldspar matrix from Mount Malosa, 5 cm in height.

Three small tan zircon crystals sit on the side of the aegirine in the middle of the cluster. Most of the aegirine looks black, but the tips of the crystals are somewhat acicular and fibrous, and a definite green color is apparent.

29th Nov 2012 01:47 GMTCraig Mercer

My favourite for today is cerussite from Nakhlak mine Anarak Iran

29th Nov 2012 13:26 GMTCraig Mercer

From me today an extremely rare Badahkshan, Afghanistan Blue/Green Aquamarine. Small cabinet. Blows me away every time I look at this one. The clarity and inclusion are mindblowing. I know, usually not two things you would put togehter, but in this case, well, it works :-)

30th Nov 2012 02:24 GMTJoo Hong

Craig, the aquamarine is intriguing! Any idea what are the inclusions?

Today I'll add a little yellow...

30th Nov 2012 11:46 GMTCraig Mercer

Joo, that thing is stunning :-) is it from Madagascar ??

The inclusions are actually Aquamarine, with feldspar underneath. I'm continuously taken back by the beauty of this specimen. Nature has no boundaries when it comes to perfection ;-)

1st Dec 2012 11:49 GMTCraig Mercer

How about this one from Shengus, Pakistan. Medium cabinet. It's a Topaz on Quartz with tectonic cracks all through it. The specimen is surprisingly stable, although it has been basically been ripped apart. There are actually small crystals within the cracks, as if they have start to reform. The top of the crystal is extremely abrasive, almost cactus like. I will post some more photo's of these specimens, detailed photo's. They are mindblowing in person.

Bahahahahaha.............I got it, it's a pistol of some sort (tu) probably a water gun. Man that's a classic Davod

1st Dec 2012 14:05 GMTLuiz Alberto Dias Menezes, Fo.

Craig, my guess is that your watermelon tourmaline is from Pederneira mine, São José da Safira, Minas Gerais; it has produced watermelon crystals with this color, and the color and shape of the lepidolite is also typical from Pederneira.

1st Dec 2012 14:18 GMTfarhad pirirani

1st Dec 2012 14:22 GMTCraig Mercer

Nice favourites everyone! John those are lovely herkimers. I just got a pair of herkimer dangle earrings for my birthday and I love them. They're not tanzanites or zircons, but I already have those :-)

My favourite today is this garnet from Finland. It has a unique charm to me because of the colourful matrix of pink feldspar and quartz.

3rd Dec 2012 03:48 GMTJoo Hong

Good day!

Craig, yes the tourmaline is from Madagascar. Sometimes I do forget to indicate the locality and dimension but feel free to click on the picture for more details.

Today's favourite is a Kaokoveld dioptase with malachite spray. It is special to me because I made the decision to trim it (with the help from Rob Lavinsky) from its original size (14 x 13.5 x 9 cm) and was lucky that the result turns out pretty good!

Here is a picture (courtesy of Rob) showing the original specimen.

3rd Dec 2012 13:05 GMTGail Spann Manager

My favourite of the day...

3rd Dec 2012 18:39 GMTIbrahim Jameel Expert

Joo, that's a really good trim/ cleaning job. It's always particularly gratifying when a good specimen becomes an even better one through the removal of a bit of dirt/ extra matrix.

4th Dec 2012 01:12 GMTJoo Hong

Hi Ibrahim, you spotted the subtle difference! :-)

I took some risk when I did the cleaning myself, using penknife, pliers and a worn-out screwdriver to remove coatings on dioptases and some matrix which obscure the malachite.

4th Dec 2012 01:21 GMTAM Mizunaka Expert

Glassy twinned calcite from Russia is today's favorite. 4.7 x 5.2 cm.

4th Dec 2012 03:26 GMTPhilip Perkins

cab size, China. largest crystal is 9cm long.

4th Dec 2012 03:46 GMTVolkmar Stingl

Hi all,

even it's boring, again a nice piece of Fluorite that i collected just 2 days ago, again in Yongping Mine, Jiangxi Province, China. Actually, this is my favorite collecting place, since it is not so far away from my work place. Each visit brings another favorite of the day to me...

The piece shows somewhat greenish to slightly purple color in sunlight, but changes to a wonderful ice-blue color in artificial light. The white material is chalcedon as remains of hollow pseudomorphs after calcite crystals.


and now in artificial light:

4th Dec 2012 09:31 GMTRudolf Hasler Expert

6th Dec 2012 03:23 GMTGeoffrey Small

Today's favorite is andradite from the Bor Pit, Dal'negorsk, Russia. Obviously not the best photo (cell phone; no camera with me out here), but you can still see the garnets. 12.0 x 11.0 x 5.0 cm.

Namibia, Africa

crystal is 2.8cm across, complete all around.

16th Dec 2012 21:27 GMTRob Woodside Manager

Lovely specimen. Here's a problem I have with damage. It can be very instructive. Your piece is undamaged and if we didn't know about these wonderful pieces you would be left wondering and suspecting a pseudo after cuprite and never suspect the gem cuprite beneath.

17th Dec 2012 06:55 GMTMalcolm Southwood Expert

Agreed Rob,

But I'm cautious about condoning those barbarians who dissolve off the malachite with acid....


17th Dec 2012 19:03 GMTRob Woodside Manager

Agreed Malcolm!

It is barbaric to damage a specimen that way.

18th Dec 2012 02:58 GMTRyan L. Bowling

Malcom and Rob,

Natural damage is one thing, removing the malachite with acid is purely wrong.

Rob, the sure weight of these pieces along with crystal shape, tells the cuprite that lies below.

Everyone, thanks for your posts. AM love the calcites.

All the best, Ryan

26th Dec 2012 02:03 GMTGail Spann Manager

Awesome photos everyone!!!!!

My favourite of the day, and I bet for ages to come, is my Christmas gift from my wonderful husband, Jim. This specimen has been on my wish list since I first saw it in Dan and Diana's booth in Tucson when they were selling Dawn and Jim Minette pieces and I had told them that I would own it one day...but I figured it would be many years. My husband knew how I felt about this, he worked it as a surprise for my Christmas gift. I couldn't be more delighted!!!! I am a HUGE fan of Veszelyite from Montana.

Photo from the Weinrichs.

26th Dec 2012 16:39 GMTVincent Rigatti

Wow that is a beautiful Veszelyite Gail, what a great Xmas gift!

My fave today is a 9 cm, 107 gram Bluecap tourmaline from Sapo mine 1990s find. This one is a little different than most from there with a thicker blue cap and sloped termination. It also is lacking the typical tan coloration in the transition from red to blue.

26th Dec 2012 18:08 GMTRudolf Hasler Expert

Phantastic tourmalin, Vincent!

My fav. today again is a specimen from Bad Bleiberg: Hemimorphite with Wulfenite and Baryte.

28th Dec 2012 12:36 GMTRudolf Hasler Expert

Great specimen, Volkmar! It is a pity we don't have Pyromorphites in Austria.

I fancy lead minerals.

Wulfenite from Bleiberg:

Many thanks for your appreciation!

Happy New Year, everyone - wonderful specimens! Here is a piece that was a Christmas gift and is my favorite today. This is the best photo I could manage while away from home.

Smoky quartz plate with Calcite from Deer Lodge Co., Montana, USA, 14 x 13.5 cm. (1/2/2013 - Correction: I tested the "Calcites" and discovered they are actually Barites)

What intrigues me about this piece is that it appears to be vein quartz (with a bit of limestone matrix still visible on one side) rather than pegmatitic or miarolitic cavity smoky quartz for which western Montana is famous.

29th Dec 2012 01:08 GMTVolkmar Stingl

Hello Rudolf, thanks, the pyro is really exceptional for its size. By the way, I am also a lover of wulfenites!

Today I show my both favourites. One is the all-time favourite (guess, which one?), and the other one the one of the day. My wife holding a nearly undamaged smoky quartz with microcline, epidote, and chabazite from Wulian, Shandong Province, China. On the occasion of the purchase of this piece I also found the pyro in my friend's mineral shop in Guangzhou, and it felt so lonesome.....

29th Dec 2012 09:43 GMTMartin Stevko Expert

My favourite of the day is fine spinel twin galena specimen with calcite, chalcopyrite and quartz from Banská Štiavnica deposit, Slovakia. Size of specimen is 75 mm. Photo by Jeff Scovil.

30th Dec 2012 04:09 GMTRick Dalrymple Expert

My favorite, and most recent acquisition. This specimen was so dirty when the woman brought it in to me at the store that you couldn't tell it was azurite and malachite. It was just a mud ball. She had it in her flower garden for years. I spent hours cleaning it.

30th Dec 2012 15:19 GMTGail Spann Manager

31st Dec 2012 01:03 GMTGeoffrey Small

Today's favorite is a huge smokey cerussite from Tsumeb. Sold a few things to get this piece- no regrets. Can't seem to get a decent photo of it, though. 18 x 15 x 6 cm.

2nd Jan 2013 01:43 GMTVincent Rigatti

Thanks for your advice. I'll definitely give it a try.


3rd Jan 2013 03:40 GMTJenna Mast

D Mike:

That is definitely one of the more unique specimens of fluorite I've seen. Excellent coloring!

3rd Jan 2013 06:35 GMTAM Mizunaka Expert

My favorite for the start of the New Year is a fluorite on a bed of spessartine garnets from China. 6.8 x 6.1 cm.

3rd Jan 2013 08:31 GMTRudolf Hasler Expert

That is really a great start of the New Year, Am!

Incredible specimen!

My fav. today is a double terminated Japan law twin from Dösen valley in Carinthia:

3rd Jan 2013 23:14 GMTVincent Rigatti

Rudolf that is a fantastic specimen. Can you provide the dimensions?

4th Jan 2013 03:31 GMTJoo Hong


Today's favourite is a heliodor from pegmatite 576, volodarsk-volynsky.

dimension : 10.0 x 3.4 x 2.0 cm

4th Jan 2013 06:36 GMTRudolf Hasler Expert

Hello Vincent,

if you click on the picture with the Japan law twin it opens up and you can see the dimensions and other useful information about it. There you also find the link that leads you to the location where the specimen was found as well as a link to the page of the user who posted it.

I find all possibilities wonderful that this platform offers! Congratulations to Jolyon Ralph!!

Why do I write this? Because I think that you should upload your phantastic photos to mindat database and I am sure most of them will find their way to the 'Best Minerals' section which actually is the part of this platform that I like most. You find the 'Best Minerals' if you scroll right down to the bottom of the message board.

With best regards


4th Jan 2013 14:02 GMTStephanie Martin

Fabulous specimens everyone! Enjoying all the wonderful photos.

Vincent, another tip if you would like to show your photo right into the post it is very simple. After you attach your picture as ususal, all you have to do is put your cursor where you want your picture to appear and click the button that is beside where your picture address is uploaded that says "create link in message". Your picture will then be imbedded in the message.

Happy New Year everyone!


Stephanie :-)

4th Jan 2013 16:44 GMTVincent Rigatti

Thanks for the advice Rudolf and Stephanie. The Mindat website is a treasure trove of great material and information and is one of my favorites. I am continually surprised by the amount of information and photos. Congrats to all members and Jolyon.

Using Stephanie's advice I am posting a favorite of mine, a small plate of Dioptase and white Calcite from Tsumeb. The plate is 12 x 7 cm. Hard to get a good photo. The real small xtals remind me of sugar candy sprinkles....

6th Jan 2013 15:38 GMTGail Spann Manager

My Favourite of the day, a Brochantite from Milpillas, Mexico.

6th Jan 2013 16:14 GMTTomasz Praszkier Manager


this is a killer! Very thick crystals and great luster! Congrats!

6th Jan 2013 21:08 GMTMichael Hopkins

wow! Simply incredible!

6th Jan 2013 23:14 GMTRock Currier Expert


If you won't upload your images directly to the mindat database, will you give permission for others to do it for you? If you do give permission, who should be credited with the copyright or would the photographer consent for them to be placed in public domain?

7th Jan 2013 00:27 GMTGail Spann Manager

Rock, I will be sure to get permission, although I have been told by everyone that I can use the photos, I will double check.

7th Jan 2013 01:35 GMTVincent Rigatti

Amazing piece Gail.

8th Jan 2013 05:01 GMTBrent Lockhart

Here is my favorite for the day, a Hematite on Quartz from

Cavradi gorge, Curnera Valley, Tujetsch (Tavetsch), Vorderrhein Valley, Grischun (Grisons; Graubünden), Switzerland

Dimensions 10 x 9 x 8 cms.

9th Jan 2013 06:25 GMTDavid Rosewall

Recently unearthed (3 weeks ago) pyromorphite from Browns Open Pit, NT Australia. As many of you know the pit filled in with water after the cyclone in 2011, but just recently the water level had to be lowered to check some problems with our water chemistry. As a result there were a few days before the water level re-established itself and some of the mud from the wall near the old dig collapsed and exposed these little beauties. Unusually gemmy from what I have seen historically and are a slightly greener colour from what I have seen before. These must have been right near our heads a few years ago but they were hidden by a few inches of mud. First we have seen at depth without any malachite or cerussite and much larger crystals. (sorry for the photo, still practising)

9th Jan 2013 11:38 GMTSteve Sorrell Expert

Wow! Gail. Big, big crystals. Nice.

Dave - special pieces indeed. I assume only a few specimens recovered?

I haven't posted a favourite for a while. I'm going with this painting finished tonight...Smoky Quartz and Microcline var. Amazonite from Smoky Hawk Mine, Jewel Pocket, Florissant, Teller County, Colorado. Based on a John Betts Fine Minerals photo, used with permission. Water-mixable oil on black card. Width of painted area is about 18.5cm.



9th Jan 2013 13:45 GMTVincent Rigatti

Great work Steve.

My fave today is a gemmy Fluorapatite on calcite matrix from Cerro de Mercado mine, Mexico. The main xtal is 3.2 cm, no contacts, and just seems to suck in the light. Was very hard for me to get a good photo.

10th Jan 2013 02:33 GMTDavid Rosewall

Here are a couple of other little oddball things that came out of the wall during the same few days. Had trouble attaching these to the last post. Steve, yes there are around 25 or so specimens that we managed to rescue before the water returned. Paul and myself are trying to get some to Tucson in time for the show.

11th Jan 2013 13:24 GMTGail Spann Manager

Great pieces everyone. Looking forward to Tucson. My favourite of the day...

12th Jan 2013 11:59 GMTRock Currier Expert


I noticed that you don't tell us how large your specimens are. At least not in the last few that you have attached for your emails. This is something that we always try to encourage new uploaders to do. Did you ever have any success double checking about the kind of copyright notice you would like on your pictures?

12th Jan 2013 15:32 GMTGail Spann Manager

I made the scrapbook page favourite of day so that people could just post without all the effort spent of measuring, if they chose not to. The point is to see the minerals, not worry about size. I know this might infuriate some, and many people do put sizes with their photos, but I want people posting just for the joy of sharing their fav. of the day.

14th Jan 2013 04:58 GMTGail Spann Manager

Okay. so I am still crazy about this gorgeous Kelly Mine Smithsonite.

14th Jan 2013 14:01 GMTVincent Rigatti

That's a Killer Gail.

My fave today is a blue fluorite with purple phantoms, and a little golden Calcite from Denton mine, Illinois.

Measures 11 x 10 x 8 cm.

15th Jan 2013 06:11 GMTAM Mizunaka Expert

Today's favorite is a twinned chalcocite crystal from the Flambeau Mine. 5.2 x 3.8 cm.

High Resolution Version Here

18th Jan 2013 11:22 GMTSteve Sorrell Expert

Elbaite from Pederneira. Water-mixable oil on black card...



19th Jan 2013 00:14 GMTColleen Thomson Expert

Steve -great painting as usual!

incidently if you squint at it with one eye ( you do.....) it looks like a frog about to 'toss the caber' (throw a log).

just sayin' :-D

19th Jan 2013 08:06 GMTSteve Sorrell Expert

Funny you should say that Colleen. Rusty James said a similar thing!



19th Jan 2013 09:57 GMTMatt Wall

Oh yeah, I see the frog as well! Nice painting though! :-)

19th Jan 2013 10:00 GMTMatt Wall

My favourite of the day, today, has to be this lovely Brookite I got from Mark Wrigley. Fully terminated and ...well... just nice!


19th Jan 2013 10:01 GMTMatt Wall

Sorry, dimensions are about 3 x 2 x 0.6 cm from the Kharan locality. :-)

20th Jan 2013 01:58 GMTVolkmar Stingl

My new favourite of the day is a newly found pyrite included calcite from Wuyi tunnel construction site in Wuyishan, Fujian Province, China.

20th Jan 2013 14:41 GMTNeal Luppescu

I just took this piece out of the cabinet for the first time in years so I could photograph it


ACF Mine, Mibladen, Morocco

8 x 8 cm

20th Jan 2013 15:41 GMTRob Woodside Manager

Some Crocoites and gemmy Vanadinites darken in the sun. I don't know if they still darken when kept out of direct sunlight. They certainly survive in the dark.

20th Jan 2013 16:50 GMTNeal Luppescu

You are right, Rob. For this reason, I keep my red Vanadinites from Mibladen and the Pure Potential Claim on a lower shelf, with no exposure to sunlight.

21st Jan 2013 04:25 GMTBarry Miller

I didn't know that the vanadinites darken from sunlight. Thanks for the info.

21st Jan 2013 06:05 GMTAndrew Tuma Expert

Good point Rob,

Tasmanian Crocoites especially some from the Adelaide mine at Dundas can be very susceptable to darkening with exposure to sunlight, even indirect sunlight. I have one specimen with fantastic termination that has really changed from a bright lusterous red to a darker duller red in arounf ten years. It has been assumed that this is due to an elevated silver content. The galena at these mines can have a very high silver percentage.

I remember Frank M showing me a flat of Chloragyrite from the Adelaide that was yellow green when uncovered and started to darken immediaterly, turning to a tarnished dark grey even when stored in a dark room because of the initial exposure.

And Steve,

Another ripper painting...(but it does have a bit of a froggy look).

Andrew T

21st Jan 2013 08:45 GMTRudolf Hasler Expert

Love Steve's Elbaite painting.

My today's fav. is Rock Crystal from Mallnitz in Austria.

18cm high. Some crystals are showing Muzo habit.

21st Jan 2013 11:40 GMTSteve Sorrell Expert

Andrew - of course you like it. It's the right cross-section!

BTW, I found a chlorargyrite at the Magnet mine one time, and watched it turn from green to greyish in seconds.

Finished this one tonight. Painted in recognition of this year's theme for Tucson, I offer up a Canadian fluorite (from Rossport, Ontario). Water-mixable oils on black card. Finished over two nights. Re-photographed in daylight.



21st Jan 2013 13:39 GMTVincent Rigatti

Rudolf that is a beauty!

Like the painting from Steve as well. How does he do that?

My fave today is from Paprok. 2 green cap tourmalines on a large smoky quartz. Measures 11 x 10 x 8 cm.

21st Jan 2013 14:39 GMTGail Spann Manager

Steve, your paintings are STUNNING. whew.

21st Jan 2013 18:12 GMTRudolf Hasler Expert


I think your Tourmaline will go right into the Best Minerals Tourmaline article if you upload it into your home page on Mindat.

For me this is the fav. of the month!

Best regards


21st Jan 2013 18:30 GMTHarry Zondervan

Going to my cabinets I came across this Kyanite on/in Quartz from Barra de Salinas, Coronel Murta County, Minas Gerais.

I bought this specimen from Mario Pauwels in 1995. It's totally gemmy and terminated on one side. When I first see this specimen by Mario I thought it was an Indicolite.

What if it was a double terminated piece?

I never seen a better gemmy Kyanite in the last 18 years.

I'm upgrading my collection but I keep this one, I think.



22nd Jan 2013 00:31 GMTNeal Luppescu

Wow, Harry. That is the gemmiest kyanite I have ever seen. In fact, I can't imagine a kyanite could get more gemmy.

My favorite for today is a calcite on sphalerite from the Elmwood Mine. I just took it out of the cabinet for the first time in years in order to photograph it.

11 x 9cm

22nd Jan 2013 01:02 GMTGail Spann Manager

HJ, that's an amazing kyanite. Very gemmy. Neal, glad you brought it out to photo, thanks for sharing.

22nd Jan 2013 01:10 GMTGail Spann Manager

Most golds do not do much for me, but this Hope's Nose gold is stunning. Great photo by our son, Tom Spann.

I love the interesting crystallization.

Hope's Nose, Torquay, Devon

22nd Jan 2013 04:19 GMTSteven Kuitems Expert

Gail, they remind me of golden down feathers in their delicate structure. Very nice specimen and photo.


22nd Jan 2013 04:28 GMTBarry Miller

That Kyanite is incredible. I've never seen one like it.

22nd Jan 2013 07:26 GMTMartin Stevko Expert

Here is my favorite piece for today. Kermesite on stibnite from Kolársky vrch antimony deposit near Pezinok, Slovakia.

Size of specimen is 10 cm. Photo by Albert Russ.

Great Calcite with good aesthetics.

Like the Kermesite and the feathery Gold too.

Will go to my cabinets once more and post some photos.

Hear from you I' ve you like them.

Regards Harry

22nd Jan 2013 18:53 GMTHarry Zondervan

Here is a oldtimer from my cabinets. It's a Turquoise with xx on mica schist matrix from the old Bishop copper prospect, one mile west of Lynch Station, Campbell County, Virginia. The piece is from 1962. Measures 7.5x3cm. In 1962 the paid 15 dollar for it. Bought the piece in 2007 and could sell it back within one month. As you can see, I didn't.

22nd Jan 2013 22:36 GMTVincent Rigatti

Thanks Rudolf. I will work on getting some of my pics loaded on my Home Page.


23rd Jan 2013 09:14 GMTRock Currier Expert

Would you consider uploading it to the Mindat gallery? It is a remarkable specimen.

23rd Jan 2013 14:07 GMTVincent Rigatti

Thanks Rock, I would be happy to post some photos, just trying to figure out how and the best way to do so on this great website.

Today' favorite is a close-up photo taken by Joe Budd of my Jonas Mine Rubellite "cluster" on lepidolite. This is a small portion of the overall piece but I like the balance and detail in the pic and the dusting of tiny pink crystals next to the larger vertical crystal which is around 2.5 cm.

23rd Jan 2013 19:18 GMTGeoffrey Small

My favorite of the day is this nice calcite specimen from Schlema, Germany. 5.5 x 4 x 6 cm.

23rd Jan 2013 19:26 GMTHarry Zondervan

My favourite of today is a lot of pink Apophyllite-(KF) with Stilbite and Chalcopyrite on matrix.

It's 8x5cm. I bought it in 2004 from Kevin Ward.

It's from the La Noria mine, La Noria de San Pantaleon, West of San Martin, Sombrerete County, Zacatecas. Mexico

This is a chain of penetration-twin crystals of Calcite from Sokolovskoe Iron Mine, Kostanay Province, Kazakhstan

8.5 cm wide.

26th Jan 2013 04:54 GMTGail Spann Manager

The Veszelyite that was delivered tonight, that Jim got me for Christmas, was looking so good and yummy I thought I would have some fun with it....

26th Jan 2013 15:55 GMTHarry Zondervan


Great piece. Did see this one in the book about the Minette Collection. I'm jealous.

Neal, very good yellow Calcite from Sokoloevskoe. In the 1990's you did see a lot of them on the show's but they seem to be al gone now.



26th Jan 2013 19:02 GMTRob Woodside Manager

That's a Killer Veselyite!!! I wonder how many pieces of that quality exist? Not many for sure!!!

27th Jan 2013 06:49 GMTSteve Sorrell Expert

My latest work, and my favourite for today is paratacamite on natrolite from Flinders, Victoria. Water mixable oils on black card...

The original specimen was collected by me in the late 1980s.



27th Jan 2013 14:04 GMTGail Spann Manager

I really enjoy the various favourites that everyone posts, what a fun way to see other's treasures. And I am sure it prompts people to pull things out and photo them, which is a good thing too. I am very grateful for your continued posting to keep this series of threads successful. Cheers.

27th Jan 2013 15:43 GMTMichael Hopkins

My favorite this morning a beautiful glassy Barite on Sulphur!

27th Jan 2013 16:21 GMTGail Spann Manager

See what I mean? Nice Mike!

27th Jan 2013 23:36 GMTVincent Rigatti

Wow Michael thats a beauty.

My faves today are 2 multi-colored tourmalines with pink caps from Paprok.

28th Jan 2013 06:24 GMTBob Jackson Expert

My favorite today just emerged from the cleaning vat. Fluorite on quartz druse, epimorphic after calcite. La Fluorita Dulcita prospect, Cochise Co., AZ Specimen is 5 X 6 cm, but hollow, so only weighs 16 gms! The epis sparkle like sugar cookies.


28th Jan 2013 12:04 GMTMaggie Wilson Expert

many thanks for your friendly comments!


30th Jan 2013 12:05 GMTVolkmar Stingl

My favourite of today is a large calcite specimen from Wuyi tunnel in Wuyishan, Fujian Province, China. At the end of last year, I was lucky to open a pocket with a lot of specimens up to 13 cm crystals (partly pyrite included), where I already had resigned. Now I am packing these pieces and I am again fascinated by them. Don't mind the poor quality of the picture, my name is not Rudolf! ;-)

30th Jan 2013 13:46 GMTVincent Rigatti

Mine today is a aquamarine on albite with some accenting schorl from Pakistan.

My photo skills leave much to be desired...

I did try to link this to my album but got an error message

30th Jan 2013 16:34 GMTPhilip Simmons

Hi all,

I haven't posted on this topic before, but I thought I would add one of my all time favorite field collected specimens. Blue halite with minor sylvite, 8.1 cm tall. This specimen was on the cover of the December 2012 Lapis issue, and is one of the many specimen photos in my article about the Carlsbad Potash District for the most recent Mineralogical Record issue (Jan/Feb 2013). I hope you enjoy!

30th Jan 2013 20:01 GMTRudolf Hasler Expert


if you want to upload a picture into your album at Mindat you first have to go to your homepage and there you click on: "My photos". Then the following button appears:"Add a new photo." When you click on that button you are right in the menu for uploading pictures. Just follow the advices given there. After one or two tries you will find it very easy soon.

Good luck!


white minerals are much more difficult to photograph than an orange Wulfenite. I don't think I could make a better picture of your Calcite than you.


31st Jan 2013 01:24 GMTVincent Rigatti

I have added photos for 17 of my minerals to date but get an error message when I try to link the URL to this topic. I will keep trying though

31st Jan 2013 01:35 GMTJonathan Woolley

Philip, fantastic piece! Enjoyed your article as well.

31st Jan 2013 08:58 GMTRudolf Hasler Expert


if you want to link an URL to this topic all you have to do is: Click on the icon with the red tourmaline.

Write the Photo Id which for instance is for your last uploaded Elbaite 51 28 97 into that box instead of the XXXX. Then your image can be seen here too.


31st Jan 2013 16:07 GMTPhilip Simmons


Thanks for the compliments. I really enjoyed writing the article, but I'm glad that it's completed. When I first started writing I didn't realize exactly how much work it would take to get the thing in presentable condition.:-D But, I'm very happy with the way it turned out.


31st Jan 2013 16:24 GMTDonald Peck

Phillip, Not only is the piece in the photo above fantastic, but so are the many others that illustrated the MinRec article. I read it with much envy! Congratulations on the experience, your finds, and the article.

Philip, I am VERY proud of you!

1st Feb 2013 03:03 GMTVincent Rigatti

Fantastic photo and article Phil. Love those blue halites. Thanks for posting

This multi-colored tourmaline from Afghanistan is today's favorite

Measures 9.3 x 4.6 x 3.1 cm

1st Feb 2013 11:40 GMTJustin Zzyzx Expert

Philip, that article was a treat to read. I've always had a major love affair with both the blue halite and the stories and photos of the huge halite crystals found years ago. Those colors are shocking, I'm so glad there was a reason to do a whole article on the location and thanks for making that possible!

1st Feb 2013 12:56 GMTSteve Sorrell Expert

Last night and tonight I painted a second Colorado amazonite and smoky quartz. This one is from the same mine as the previous one posted (Smoky Hawk claim, Crystal Peak area, Teller Co., Colorado, USA), but the amazonite is much bluer and the smoky quartz brown rather than black. Interesting how the two forms can occur so close to one another. Rob Lavinsky specimen, painted with permission. Water-mixable oil on black card.



1st Feb 2013 16:02 GMTPhilip Simmons


Thank you so much for your compliments! I truly am grateful for all of the wonderful people that are a part of this amazing hobby. The two things I love most about mineral collecting are the people I get to meet and the experience of finding such great treasures. I am humbled and blessed to be able to share my experiences with people who love collecting minerals as much as I do.


3rd Feb 2013 20:48 GMTGerhard Brandstetter Expert

Curly Malachite from Mockleiten, Brixlegg mining area, Tyrol, Austria, 15 mm aggregate. One of my absolute favourite Thumbnails.

I did not post here for a while, but i visit this nice thread nearly every day, usually with my morning coffee.

So fine things to see!

4th Feb 2013 04:54 GMTMark Stanley

Here is mine for today.

Azurite: Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA, 3 cm

A complete floater

4th Feb 2013 12:07 GMTRudolf Hasler Expert

Great specimens and photos, Mark and Gerhard!

I enjoy the pictures I can see at this thread.

5th Feb 2013 00:18 GMTWynne Keller

The minerals that show up here are so awesome, and the photography is amazing as well!

I've recently been going through my specimens from England, and this large barite from Egremont, Cumbia is my latest favorite. It was obtained from the Harvard Museum and measures 20 cm long

5th Feb 2013 13:23 GMTGail Spann Manager

Like Gerhard, I am sitting here with morning coffee and thinking about how we are seeing minerals on this thread that, otherwise, might never be seen. Again, everyone, thank you

5th Feb 2013 13:45 GMTVincent Rigatti

I agree with Gail, thanks for all the great photos. Like a new museum exhibit every day.

This dark green Elbaite from Paprok is attached to a white Albite. The Elbaite is 5.75 cm tall

5th Feb 2013 14:29 GMTMartin Rich Expert


your photo is for me "the photo of the day". Great specimen!

5th Feb 2013 16:48 GMTGerhard Brandstetter Expert

From the same photo session one of my other alltime favourites:

I also found a nice thread here:

Because i know it is Galena indeed i'm sitting here with a big smile on my face.

Whatever you think about it - enjoy !

6th Feb 2013 08:51 GMTSteve Sorrell Expert

Finished last night. Rhodochrosite with quartz and tetrahedrite from the Sweet Home Mine, Pincushion II pocket, Alma, Colorado. Original specimen is 9.6x6.2x4.2 cm. Water-mixable oil on black card.



6th Feb 2013 18:19 GMTJames Pool

Here's my first entry in the favorite of the day thread. It is a Vesper Peak Grossular garnet that I purchased last year at the Denver Gem and Mineral show. Formerly from the Zinn collection. I was testing out a temporary macro photography setup that used a glass plate, a cardboard box, a old dark blue scarf for background. I used a Pentax K-01 mirrorless camera with an old 50 mm f4 macro lens and indoors with daylight for the white balance. A Tiltall tripod was used and a stack of 5 shots was processed in CombineZP. Not bad for a first try especially as the garnet was still attached to the perky box.

Anyway I love garnets and that mineral species is the focus for my purchased collection.

7th Feb 2013 03:14 GMTNeal Luppescu

My last offering before heading to Tucson is an Apatite surrounded by Calcite from Panasqueira, 7.5 x 6.2cm.

8th Feb 2013 10:01 GMTRudolf Hasler Expert

My today's favorite: Rutilated Quartz from Heiligenblut, Austria.

Can you guess where it got the green color from?

8th Feb 2013 15:35 GMTAdam Kelly

Wow Rudolf!

What is the size of that piece?

8th Feb 2013 17:01 GMTGerhard Brandstetter Expert

Fine specimen, Rudolf! The green color is possible from Chlorite or Fuchsite i suppose.

Nice greetings from Steyr, Gerhard

8th Feb 2013 18:38 GMTDon Saathoff Expert

Adam, a click on the image takes you to the gallery page for the specimen (and also answers Rudo's question)

9th Feb 2013 11:53 GMTVachik Hairapetian Expert

My today favorite is an aesthetic museum cluster of variably sized, well separated quartz crystals (just arrived). The specimen is 25.5 cm in width and the largest raised crystal (left) is 12 cm in height. Considering a set of nice characters of the specimen, this is one of few best specimens I have ever seen to date from the Ghale Zari Mine, Eastern Iran. There are calcite and gypsum crystals (the latter is on the rear side, see

9th Feb 2013 16:34 GMTWaterDog

Goethite, Sellwood Mine, Ishpeming, Michigan, USA

This is one of my oldest specimens and still one of my favorites.

9th Feb 2013 16:59 GMTRudolf Hasler Expert


Don Saathoff has already showed you how to find the answer to my question about the green Rutilated Quartz. This is really a queer specimen as it needs light to keep the bacteria.alive otherwise the nice green color would turn to grey or brown. So I have to take care to switch on the lights for some minutes every month.


9th Feb 2013 17:31 GMTRob Woodside Manager

In the immortal words of Dr. Frankenstein, "It's Alive!!!" Does it need a drink once in a while?

9th Feb 2013 18:47 GMTStephen Rose Expert


Don't we all?


9th Feb 2013 22:17 GMTDavid Zimmerman (2)

Way too funny Steve!!!

Rudolf, that has got to be one of the stranger quartz specimens I've ever seen. It's absolutely gorgeous! What other maintenance does that bacteria require? Is it thermally sensitive as well? Are these available on the market or mined by anyone in particular? I'm going to have to do some searching......

My favorite today is a small plate of rhodochrosite-quartz-and small blue fluorites.

Here is a zoom pic

Hello David,

the specimen with the cyano bacteria was found in an alpine cleft last year. It was the only piece with the green color. Luckily the specimen did not need any cleaning at all as it hung from the ceiling of the cleft.

Under microscope we saw that the color originated from tiny cracks in the crystals what made us think that it must be something organic.

The solution was found by Jens Köhler in the German platform:,29684.msg229146.html#msg229146 : Cyano bacteria. They are most common and were the first bacteria on earth. You have them in aquariums if the glasses are not cleaned regularly.

Is it safe to assume that the piece was found in a breached pocket that then had exposure to sunlight, as well as frost and freezing? I did some research and your piece does indeed seem to be unique on the internet, with no others being similar. Congratulations on acquiring such a rare piece. Who said quartz is not rare enough to bother collecting?!?

10th Feb 2013 19:04 GMTRudolf Hasler Expert


as the specimen was rescued by a very good friend of mine who does not tell lies it is absolutely safe that it was found in an open cleft with exposure to sunlight, as well as frost and freezing.

Thank you very much for your research.

With best regards from Austria

Today's fave is a dark green Elbaite from Paprok, Afghanistan attached to a white Albite crystal. The Elbaite is around 6 cm. tall

14th Feb 2013 15:23 GMTBob Griffis Expert

Vincent, Nice tourmaline!

14th Feb 2013 17:41 GMTJames Pool

Here's a nice sculptural galena from the Tri State Area of Missouri, no more detailed location detail than that. It measures just over one inch at the widest point and was picked up at one of the silent auctions a few years ago for one of the local clubs in the Denver area. This was from a stack of 10 photos on the first test of my home made macro glass sheet shooting stage using a tripod and a 50mm macro lens on my Pentax K-01. I need to get black velvet as black felt just isn't dark enough so I angled my two led lights to make the background light instead. I plan to use more lights and the subject at a different angle to capture more of the sculptural detail.

15th Feb 2013 18:51 GMTJames Pool

My favorite of the day is this self collected pyrite ball from Holcim Quarry, near Florence, Colorado. It measures about 19 mm on the longest axis. Some gamma and saturation correction was added to make the background darker and show more detail on the faces. Taken on a homemade macro stand with a Pentax K-01 and a 50 mm macro lens.

15th Feb 2013 19:05 GMTRudolf Hasler Expert

Congratulations, James! That is a phantastic specimen you‘ve collected - a natural work of art.

My fav. of today also is self collected: Fluorite from Austria.

24th Feb 2013 07:09 GMTDr. Paul Bordovsky

Some fine specimens today, with lots of color. Nice mimetite, Michael.

Interesting amethyst, Brent...very cool form.

AM.....always the sharpest, detailed photos, with the added bonus of being a great specimen with saturated color.

And Neal, nice form on the fluorite from Mongolia.

Are these recent Tucson acquisitions?

Here is a cousin of Neal's specimen. Fluorite from Mongolia 68x65x83mm

This crystal has pink phantoms, and a dark phantom of metallic inclusions along a growth plane.

Diana and I picked up the Mimetite at The Tucson City Center this year. What a great show. We picked up another that we will be posting later.

24th Feb 2013 17:41 GMTBrent Lockhart

The Amethyst is an acquisition in the last 3 weeks, but not at the Tucson show.

A beauty, Neal.

25th Feb 2013 20:42 GMTPhilip Perkins

Wonderful minerals everyone.

Neal love your Elba Pyrite, your Mongolian & South African Fluorites, thanks for sharing.

Dr Paul your Fluorite is fantastic too.

26th Feb 2013 01:37 GMTNeal Luppescu

Cerussite cyclical twin, coated with acicular mimetite, and sprinkled with a few bits of malachite. From Tsumeb, of course.

I'm not sure what the orange material is in the lower right hand corner. Perhaps dolomite or calcite, with hematite inclusions. 6cm wide.

26th Feb 2013 11:10 GMTRudolf Hasler Expert

Gorgeous specimen, Neal!!! The orange material??? Have you considered Wulfenite?

My fav. is Wulfenite from Bad Bleiberg. (I hope I have not shown it already before. I start forgetting such things.

26th Feb 2013 13:56 GMTVincent Rigatti

Wonderful pics everyone. Love the fluorites. Rudolf that Wulfenite is a beauty.

I noticed I double posted a piece on this thread recenty, my apologies.

Today is a cluster of green elbaites with complex terminations in a terminated quartz

27th Feb 2013 23:16 GMTPhilip Perkins

This is one sweet little specimen that i acquired in Tucson 2013.

Pyrite & Quartz.

Spruce Ridge Mine, King County, Washington.

size 5.5cm high.

27th Feb 2013 23:37 GMTPhilip Perkins

This favourite is that last little guy's big Brother, also acquired in Tucson 2013.

As always, great to see such fine specimens, thanks for sharing. I also love to see the Swiss pieces, AM, that is an amazing piece from that location.

Here is my favorite today, my only piece from Tucson this year.

Garnet var. Grossular

Jeffrey Mine, Quebec, Canada

Specimen is 4.8cm tall, garnet perched on top is 1.6cm across, with no damage. The garnet is about 330 degrees all around.

3rd Mar 2013 16:46 GMTDavid Zimmerman (2)

Great piece Ryan, with wonderful presentation of the main crystal. You, more than most, can certainly appreciate how rare they are....especially the spherical crystal shapes. I'd guess that there are a thousand hemisphere garnets found for every one that is a sphere from Jeffreys.

3rd Mar 2013 19:26 GMTRyan L. Bowling


You are so right, I appreciate how hard these are to find, and I really enjoyed the days spent at the Jeffrey Mine.

Good to hear from you, heard your heading West?

3rd Mar 2013 20:09 GMTDavid Zimmerman (2)

I'll find out if the "West is the Best" in exactly 2 weeks from now. I'll email my contact list all the details when I get settled in out there. I'm looking forward to doing a lot of mineral exploring and mountain hiking in British Columbia. A good chance that I'll be making another trip down to CO this summer. We'll keep in touch.

3rd Mar 2013 20:57 GMTKnut Eldjarn Manager

My favorite of the day just arrived from John Veevaert of Trinityminerals - thanks John ! It is a very unusual Rhodochrosite from the Wutong Mine in China said to come from a very small find last year with flattened crystals to 1 cm on quartz exhibiting a deep pink core with a light pink outer layer. It has been compared to red and pink jelly-crackers. Since I could not visit the Tucson shows this year I followed all online reports and found a picture of this specimen said to be offered by John Cornish. I immediately e-mailed John Veevaert who could tell me he had just purchased the specimen for resale - and then it ended in the collection here. It can be considered a reverse habit compared to the famous wheat-sheaf crystals from the N`Chwaning that showed deep red crystals growing on a core of light pink Rhodochrosite. I think it will be a favorite in the collection for a few days to come..

it's fantastic, thankyou for sharing your acquisition.

3rd Mar 2013 22:32 GMTJim Robison


Your fastastic rhody is the envy of many. John Veevaert, and John Cornish, both told me they had received many phone calls and emails asking about the rock after Crystal Classics first showed the specimen on one of their show blogs. Glad to hear that you got it, even though I've several friends who were genuinely dismayed that they missed it.The piece surely qualifies as a prime favorite of the day/week/month/etc.

9th Mar 2013 07:57 GMTRyan L. Bowling


I love your rhodo, here is one that is similar to it, without the two tone crystals. I like this one, because it has pyrite sprinkled on the edges of the blades. To me, these are really unique rhodos.

5.4cm across, from the Wutong Mine, China.

9th Mar 2013 08:18 GMTKnut Eldjarn Manager


a lovely rhodo and clearly a close relative to the one in my collection. Especially with a common mineral like rhodochrosite I find it fascinating to identify "signature specimens" with habits and associations unique to the different important specimen producing localities. I think in addition to the famous huge crystals these flattened and sometimes two tone crystals will be among the signature specimens from the Wutong mine. Thanks for posting.

9th Mar 2013 12:59 GMTPhilip Perkins

Ryan I love your Rhodo mate, real neat with the sprinkling of Pyrites on the edges of the blades, reminds me of my Chinese Calcite,

thanks for sharing, sorry thhat i missed you in Tucson.

This Elbaite from Barra de Salinas, Minas Gerais, Brazil was found in the 1960s.

It has quite unusual colors for a tourmaline.

7.5cm in height.

16th Mar 2013 02:24 GMTJim Bean

My favourite of the day: Vanadinite on Baryte, 9 x 6.5 cm. From Mibladen, Morocco. I think it is the world´s best Vanadinite occurrence.

18th Mar 2013 09:27 GMTRudolf Hasler Expert

18th Mar 2013 22:39 GMTHarry Zondervan

My favorite of today is this small Prehnite of 3.4x1.8x1.4cm

There are small Inesite xx, Apohyllite-(KOH) xx, Pectolite xx and Datolite xx on the piece.

They were found in april 2000 in the N'Chwaning II mine, Kalahari Manganese Field, Northern Cape Province, South Africa.

It was a one time find and I like them because they are a totally strange manifestation of Prehnite. Not comparable with the green Prehnites from all around the world or the yellow Prehnite from Tanzania or the Prehniet xx from the Jeffrey mine.



23rd Mar 2013 16:14 GMTRudolf Hasler Expert

Harry, I forget my mouth open when I look at that gorgeous Prehnite of yours. Please, do upload it into the Mindat gallery!!!

Hello again,

Thanks for the beautiful minerals and the nice pictures everyone!

I haven't posted for a while mainly because my old camera was broken.

When I was photographing a nice rose quartz from Galilei I found out she was apparently not in the mood for a photoshoot. After a couple of shots she used the laws of gravity to headbutt my defenseless lens, leaving a deep scratch.

Fortunately my birthday is coming up and my father already donated a replacement.

From the first session with the new camera is the next picture from an amethyst from Vera Cruz. (no postproduction whatsoever!)

Measures: 7 x 5 x 3cm.

30th Mar 2013 21:50 GMTVincent Rigatti

6 x 6 cm

8th Apr 2013 12:19 BSTRock Currier Expert


Did you get underground at Chah Kharboze. Does that translate in English to something like shaft melon? Do you have proper equipment for working in abandoned mines? I was there about 6 months before the Shaw was kicked out and although I saw thousands of tiny red wulfenite fragments on the ground I didn't try and go underground because I didn't have a proper light, ropes or even a hard hat. I have heard that it was dangerous. What makes it dangerous. I heard that the second level was full of water and that was where the better wulfenite's came from.

8th Apr 2013 17:20 BSTPhilip Perkins

Neal your Barra de Salinas Elbaite is wonderful & so is your Dolomite, just love the twinning, if you see another like it, please do let me know,

thankyou for sharing those two beautiful pieces.

9th Apr 2013 03:24 BSTNeal Luppescu

This is an interesting crystal in that it is twisted, reminiscent of a quartz gwindel. Are there any minerals besides quartz that guindel? I suppose this would be an interesting question to post on its own, elsewhere on the message board. Perhaps the best way to describe it is a stack of crystals in a sub-parallel array.

In any case, enjoy this Arsenopyrite from the Yaogangxian Mine, Hunan Province, China.

5cm in height.

9th Apr 2013 19:17 BSTRonald J. Pellar Expert


In answer to your question, "Are there any minerals besides quartz that guindel?" Here is a twisted realgar from China.

9th Apr 2013 23:42 BSTVolkmar Stingl

Soirry Ronald,

but in my opinion this realgar has nothing to do with a gwindel. For me it looks like a somewhat distorted crystal of realgar, not like an oriented parallel growth of several crystals.


10th Apr 2013 06:09 BSTAM Mizunaka Expert

A cluster of quartz with a pale lavender fluorite cube from Spain is today's favorite. 7.5 x 8.7 cm.

10th Apr 2013 16:15 BSTKarsten Ivan

Some gypsum and calcite crystals are time to time ordered parralel with results as "gwindel-like"

10th Apr 2013 19:11 BSTRonald J. Pellar Expert


What distinguishes a completely closed gwindel from a twisted crystal? The realgar is definitely twisted. The stacking of numerous crystals with small offset is a mechanism for generating gwindels. So does the generation mechanism define a gwindel or does the result, i.e., twisted crystal, define the gwindel?


10th Apr 2013 23:38 BSTMalcolm Southwood Expert


Really interesting question on other minerals that form gwindels. I've been thinking about the twists in these xenotime crystals for some time. This one is 27mm long and from Zagi Mountain in Pakistan. Honestly not sure if the term "gwindel" should be applied here; time to do some homework!



11th Apr 2013 01:58 BSTNeal Luppescu

Great piece, Malcolm. Now that I think of it, I have seen a few xenotimes like yours that definitely have a twist to them. The one whose photo you provided seems to have a smooth rounded twist like what I think should be present in a gwindel, rather than the stepwise choppy twist shown in my arsenopyrite. Why should a tetragonal mineral like xenotime form a gwindel like quartz, which is hexagonal? Beats the heck out of me.

So I guess my favorite today will be a Quartz gwindel, from St Gotthard, Ticino, Switzerland,

10 cm in height.

11th Apr 2013 02:01 BSTVolkmar Stingl

Hi Ronald,

as far as I understand is a gwindel a formation of stacked crystals along an a-axis with some twisting. Your realgar seems to be a single crystal that is distorted, and, therefore, can not be classified as a gwindel (only my personal opinion!).

See also

Maybe, my understanding is wrong, but stacking of several crystals with twisting seems to be defining a gwindel.

Looking forward to more comments on this interesting topic.

Take your rock to a gem dealer, who may physically test it for you if he feels interested.

As unfortunately most of the people who frequent this forum don't have physcic abiliites, a few not so sharp photos of a clear bit of rock don't help us to make any informed judgements.

Thats why you dont have any answers to your question...hint

That's a wonderful photograph of a specimen that looks as though it should grace the pages of a pathology manual!

AM, your pieces are outstanding.

Variscite, lovely !!! On display at the Houston show this weekend, truly fabulous eye catcher.

30th Apr 2013 11:05 BSTSteve Sorrell Expert

Came across this one a few days ago. A lovely little micro.



30th Apr 2013 12:54 BSTMalcolm Southwood Expert

Great specimen Steve, and good photo!

Where's it from?


30th Apr 2013 13:04 BSTSteve Sorrell Expert

Hi Mal. Click on the photo :-)



2nd May 2013 13:31 BSTSteve Sorrell Expert

I quite like this sulphur from Texas, ex Al Ordway, and interestingly for an American specimen, labelled "sulphur" not "sulfur".



2nd May 2013 19:24 BSTVincent Rigatti

My favorite today is a complex Rhodochrosite rhomb with hubnerite, quartz and pyrite. From Sweet Home mine in the beautiful Colorado mountains near Alma. Main xtal is around 5cm across

3rd May 2013 05:56 BSTAM Mizunaka Expert

An old time classic Rhodochrosite from the Hotazel Mine is today's favorite. 4.3 x 4.2 cm.

3rd May 2013 22:26 BSTLeor Goldberg

O.O I'd sell most of my collection for that rhodo..

7th May 2013 03:01 BSTJoo Hong

After a long break from posting, I'm back here with my contribution for today.

-- a multi-color tourmaline from madagascar, 78 x 34 x 33 mm

7th May 2013 03:44 BSTChris Stefano Expert

Picked this up on the way home from the Rochester Symposium. Old classics make me happy :)

Zincite crystal- 5 mm on calcite. Franklin, New Jersey.

8th May 2013 04:23 BSTTimothy Blackwood

This is from a small rock and mineral show that was held May 4th and 5th in Brainerd, Minnesota (USA). I love it! :-)

Rhodochrosite with Fluorite

Uchucchacua Mine, Oyon Province, Lima Department, Peru

8.8 x 6.7 x 5 cm.

A fine small cabinet specimen of rhodochrosite crystals on matrix from the Uchucchacua Mine, in Peru. The scalenohedral crystals reach up to 1 cm (most are smaller) and have glassy luster and a deep rose-red color. Many are doubly terminated. Micro colorless fluorite cubes are visible upon close examination. Tim Blackwood specimen and photograph.

Hope it's okay to include the close-up. It's not that much closer, but I thought it would show the crystals (including the small fluorites) better.

8th May 2013 12:51 BSTVolkmar Stingl

Hi everyone,

I also want to contribute to this thread again and present nice zoned calcites with pyrite (partly as needle pyrite) inclusions. I found this 10 cm specimen at Wuyi tunnel construction site, Wuyishan Co., Nanping Pref., Fujian Prov., China.


8th May 2013 13:01 BSTBrent Lockhart

Here is a new addition, a Barite from Milpillas measuring approximately 15 cms. across. It is from the recent find there.

Tourmaline from Tamponilapa, Madagascar.

50 x 25 x 23 mm

14th May 2013 12:13 BSTSteve Sorrell Expert

Last week, I had a short holiday in New Zealand. I repatriated this specimen :-D

Gold, Ballarat, Victoria

Found in the early 1990s on the railway line near the old Black Hill workings close to the site of the Welcome Nugget discovery location. The quartz boulder must have been used as ballast on the railway line until school children found it and happened to break it open. It obviously is an alluvial boulder from the deep lead workings judging from its rounded shape. Quartz is 70x60x45mm. Gold area is about 7.5mm across and is crystalline.

It made it over to New Zealand in the 1990s and has now returned home.



16th May 2013 19:16 BSTRudolf Hasler Expert

My today's fav. was recovered the day before yesterday:



16th May 2013 19:28 BSTJonathan Woolley

Beautiful, Rudolf. Congratulations!

16th May 2013 19:58 BSTVincent Rigatti

A beauty Rudolf. Is there a touch of purple in the main crystal?

My fave today is a grouping of light green fluorites on matrix from China. The piece is 11 cm long.

16th May 2013 23:52 BSTMartin Rich Expert

Time for a new post.

My favourite today is an european classic: Wulfenite from Mežica, Slovenia. Crystal size is 1 cm. This specimen is in the collection of a slovenian friend. Note: the photograph shows the real colour!

17th May 2013 00:22 BSTRudolf Hasler Expert

A beauty Rudolf. Is there a touch of purple in the main crystal?

No, it is a water clear colorless crystal.


outstanding color of a European Wulfenite!!!!



17th May 2013 02:48 BSTBob Harman

Composed of 2 common Midwest minerals I found this 15 cm x 8 cm quartz and calcite specimen very esthetic. The groups of milky quartz crystals are grouped and sprinkled over the 5 cm calcite in a very sculptural manner. There are 2 minor groups of red dolomite crystals as well. From Monroe county, Indiana CHEERS............BOB

A newly acquired example of a "common" mineral from a rare locality: a crystallized Gold from Virginia. Ex Chicago Field Museum collection.

18th May 2013 13:49 BSTVolkmar Stingl

Now my first day at the 1st Changsha Mineral & Gem Show is over. Seeing so many wonderful things, it is hard to decide which one is my favorite for today. The easiest way is to choose a well-known one: the "Empress of China"! This rhodo is just stunning. No more words necessary...

18th May 2013 16:02 BSTDonald Peck

WOW !!!!!!!!

20th May 2013 09:41 BSTVolkmar Stingl

Another piece, that highly impressed me at the Changsha show, was this largest morganite ever found in Pakistan (about 35 cm, I estimate), owned by The Arkenstone. The poor photo can not reflect the unbelievable quality of this giant piece.

20th May 2013 13:15 BSTLeor Goldberg

Hardly on par with the previous two pieces, is my favorite for today. An erythrite from Bou Azzer.

23rd May 2013 01:58 BSTVolkmar Stingl

My favorite of the day is a nearly "invisible" fluorite from Xianghualing, Hunan, China. I found this wonderful piece in Changsha for an affordable price, so now I can admire it every day... Size: about 15 cm.

23rd May 2013 13:29 BSTRudolf Hasler Expert

Great Fluorite, Volkmar!!!

My fav. of today is last week's recovered Sceptre Quartz from Goldberg group in Carinthia.

Size: 9,5cm.

25th May 2013 09:52 BSTValere Berlage

Plancheite/shattuckite with minor malachite, covered with quartz, Likasi area, RDC (7.5 cm)

By far my favorite radial plancheite so far, this specimen really has something special!

26th May 2013 19:46 BSTRonald J. Pellar Expert

Here is my favorite for today, a 37 mm high tourmaline from Stak Nala, Pakistan.

27th May 2013 02:38 BSTJim Bean

I love how that quartz shaped up in the end, Rudolf! I also find Valere's radial plancheite a very interesting specimen

29th May 2013 00:14 BSTJoan Kureczka

Joo --

While the 2nd tourmaline you posted is certainly Madagascar, the first one appears to be a Himalaya Mine specimen. I've certainly never seen anything from Madagascar remotely like it. Whereas it's pretty typical for that California mine.

Joan Kureczka

29th May 2013 02:09 BSTJoo Hong

Hi Joan,

I think you mean this:

I got it from Tomasz Praskier five or six years ago. Given his vast experience in Madagascar, I didn't question the locality info provided.

Indeed the colours looks untypical of tourmaline/liddicoatite from madagascar. Thanks for bringing this up. Since Tomasz is also in this community, I would appreciate if he can help on this.

30th May 2013 16:39 BSTJoo Hong

My favourite today is a recent addition - red elbaite on lepidolite set on feldspar.

3rd Jun 2013 13:46 BSTGail Spann Manager

Went to the Heritage Auction and won this, yesterday, in Dallas.

Keweenaw mine peninsula, Michigan. 7.6 cm by 6.4 by 3.8 cm. Copper "skull" with dodecahedral crystal of copper inside. Love this!!!!

3rd Jun 2013 19:43 BSTDonald Peck

Gail, are you sure that is copper? I think it is a gem!!!

4th Jun 2013 19:32 BSTRudolf Hasler Expert

My today's fav. is a small but extraordinarily clear group of Rock Crystals that I recovered yesterday.

5th Jun 2013 13:36 BSTGail Spann Manager

Donald, you are always such a delight...

We added this beauty to our collection and are just delighted to have it in our Bisbee, Arizona suite. 8.9 cm x 11.4 cm x 7.6 cm Calcite. Also known as CAVE POPCORN.

21st Jun 2013 12:35 BSTSteve Sorrell Expert

One of my favourite thumbnail specimens. The large azurite is 14mm across. Nice to see some reflections underneath the azurite crystal on the right too. Stack of 9 images. Ex Al Ordway. Gift from D. Pohl.



22nd Jun 2013 14:56 BSTGail Spann Manager

Steve. wow!

25th Jun 2013 12:17 BSTSteve Sorrell Expert

This specimen arrived in today's mail...wulfenite and dioptase, Tsumeb. Wulfenite crystal is 2mm across. Stack of 18 images.



26th Jun 2013 01:04 BSTGail Spann Manager

I love this Rhodochrosite from the Sweet Home Mine, and after showing minerals to friends this week, and seeing their reaction to minerals and this piece in particular, it is my favourite of the day.

26th Jun 2013 04:03 BSTAndrew Tuma Expert

Hey Steve, so are Mal and I are finally rubbing off a little of ourTsumeb influence on you....a very wulfie and dipotase.

And Gail..there are no Rhodos like SHM rhodos and your is a very nice one.


26th Jun 2013 04:20 BSTJohn M Stolz Expert

That rhodo is out of control

26th Jun 2013 19:11 BSTStephen Rose Expert

My friend Ken Hoffman showed up with this specimen today after he finished cleaning it up. He collected it at the Happy Claim (AKA CK Claim) a couple of months ago. It is one of the best clusters I've seen from the area and the associated DT tabby is really interesting. 12x10x5 cm. Bottomly prospect area, Pershing County.



27th Jun 2013 02:10 BSTJohn M Stolz Expert


This is my favorite today...

I aspire to blowing Gail away with a comparable rhodo some day... :-)

28th Jun 2013 18:35 BSTJoo Hong

Today's favourite is an ajoite quartz from messina mine.

Just arrived recently and it was the blue I was seeking.

29th Jun 2013 12:07 BSTAM Mizunaka Expert

Fluorite from the La Fluorita Dulcita Cu prospect is today's favorite. 7.9 x 7.9 cm.

29th Jun 2013 13:52 BSTSteve Sorrell Expert

Dehne McLaughlin has mined some very nice azurite suns over the last few years. This one painted tonight (water-mixable oils on black card)...



5th Jul 2013 01:15 BSTJoan Kureczka

A recent acquisition from one of my favorite North Pennines locations, Rotherhope Fell. These were mined in the 1920 - early '30's period, and rather hard to come by. The best selection is in the Natural History Museum in London, as part of the Sir Arthur Russell collection.

Small cabinet sized fluorite with calcite.

7th Jul 2013 10:53 BSTVachik Hairapetian Expert

A gorgeous and impressive specimen of lustrous bright/dark green Andradite (var: Demantoid) from a new find/new locality. The new locality is on the southern flank of Belqeys Mountain, 34 km NE of Takab, NW Iran. The crystals are nicely terminated – the larger one is 1.6 cm. The specimen is 5 cm in length.

9th Jul 2013 02:44 BSTNeal Luppescu

Here's a piece i've had for about 7 years, but had trouble taking a good photo of it. I finally figured out what to do with the lighting to bring out the fan-like arrangement of the crystals. It is my favorite photo of the day.

Hemimorphite from the Ojuela Mine, Mapimi, Durango, Mexico. 6cm wide

11th Jul 2013 18:47 BSTVachik Hairapetian Expert

Gorgeous piece of Iranian mimetite in orange-red color. 6.5 cm height.

15th Jul 2013 20:14 BSTGail Spann Manager

Neal, you found my weakness, hemimorphite from Mexico. That one, by the way, is beautiful.

I fell in love with this piece this week, and it is now in our collection. Opal over Ikaite "pineapple" from New South Wales, Australia. White Cliff opal fields.

16th Jul 2013 00:07 BSTGail Spann Manager

Hey everyone, let's CRANK this thread up a bit and start posting your favourites of the day!!! Got any great photos from museums? Friends collections? ( with permission, of course!) How about that box of minerals hidden under the bed? Use your smart phone, use your nice camera..whatever, but let's see what strikes you every day!!???

16th Jul 2013 01:22 BSTJohn M Stolz Expert

Well... OK Gail!

This is my favorite and I haven't even received it yet! I'll probably get this little fellow trimmed...

16th Jul 2013 01:50 BSTGail Spann Manager

Whooppppeeeeee John! Thank you for cranking it up! Nice photo!

16th Jul 2013 01:59 BSTNeal Luppescu

This has been my favourite for a while. Polished thomsonite nodule still attached to basalt host. Thomsonite beach, Grand Marais, Cook Co., Minnesota, USA. Thanks to John Truax for the fine effort and striking result. Will upload (as promised) when I have the dimensions.


stephanie :-)

16th Jul 2013 06:25 BSTBrent Lockhart

I was enjoying this Smoky Quartz gwindel on its new base and thought I'd share it. The specimen is 12.5 cms. across and is from the Zinggenstocke, Grimsel, Kanton Bern, Switzerland. The xl is glassy, relatively flaw free, and clear enough to see through without strong lighting.

16th Jul 2013 13:16 BSTSteve Sorrell Expert

Tiny, but oh so cute!



17th Jul 2013 04:00 BSTGail Spann Manager

You are all so wonderful, thanks for being CRANKY !! Ha ha. Neal, never cranky enough!

19th Jul 2013 00:12 BSTNeal Luppescu

This siderite after calcite is from the Gheturi Mine, Turt, Romania. 11cm in height.

There's an interesting band of tan coloration amid the reddish-brown crystals, perhaps calcite or dolomite?

19th Jul 2013 02:13 BSTLeor Goldberg

Kutnohorite from Wessels Mine in N'Chwanning. I love it. :-D

7th Aug 2013 19:06 BSTTony Charlton

as a new member of mindat i have enjoyed all the information and mineral pictures.

in 1996 i collected these micro azurite crystals at the kelly mine Magdalina NM.

could not decide which i like more today so posting both... well they are on the same rock.

hope yo'all like them


8th Aug 2013 04:27 BSTTony Charlton

by my clock its still the same day, however the mindat clock says it is tomorow so here is my new submition for mineral of the day.

in october 1999 i found a vug of large smokey quartz crystals 5"-8" in length. on either side of the large crystals there was a dramatic reduction in the size of the crystals. to less than 1". there was a change in the nature of the small crystal area also, as most of the small quartz had rutile with it.

i placed some large pieces of pocket clay in my pack to clean up later, hoping to get some rutile needles fom it. this little beauty came out also and has been a daily favorite of mine for meny years now. the quartz crystal is 3/4" long and has a V of rutile on the exterior.

the location is Quintett, El Dorado co., CA, USA

ynot rock


P.S. have only read the list to feb 2012 . am totaly suprized by the unique and beautiful pictures. looking forward to catching up with the blog!

9th Aug 2013 01:07 BSTJoo Hong

My favourite today is a twinned quartz with two distinct ajoite phantom points encased within. Part of the prisms of the 2 phantoms points are visible.

Quartz is one of my favourite but I have not seen such growth habit before.

I read that there are four known contact twin laws : Japanese, Esterel, Sardinia, Breithaupt (American Mineralogist, vol. 34, pg 142-162). Other than the first, I have no idea how the others look like. Could this be one of such twin?

9th Aug 2013 04:15 BSTTony Charlton

heres my favourite of the day, today. a staurolite from Pillar, NM, USA. (near Taos).

a "mother and child" it also has a little pyrope ( rock currier says it is spesertine) on the side.self collected in 2006 on a return to home state rock-hound trip.
the larger crystal is1.5" in length and the smaller one is 0.5" in length

9th Aug 2013 20:20 BSTVincent Rigatti

Brown fluorite on Celestite matrix, Clay Center Ohio.

9 x 11 cm

9th Aug 2013 21:56 BSTJonathan Woolley

I finally got a friend to take a decent photo of this micro - one of my favorites for a while. It is an Olivenite crystal grown directly over a small crystal of Zeunerite from the Majuba Hill Mine. Looking through the microscope, it looks like an eye looking back at you.:-) It was collected by Jeff Hill a few years ago.

10th Aug 2013 03:10 BSTLeor Goldberg

@Gail, Having seen the photo you uploaded of your Veszelyite you posted earlier in this thread, your compliment on my own made my day :). My favorite for today is a Kutnohorite from the Wessels Mine in N'Chwanning, South Africa. It's even nicer in person IMO.

Edit: It appears I already posted this piece to the thread, Woops.

10th Aug 2013 19:45 BSTTony Charlton

this quartz crystal was found as float on a logged mountainside in May 1999, I saw the red flash from 20 meters away. altho meny viens with vugs have been found there sence then,the one this piece came from has remained hidden(if it still exists).the crystal was serface frosted,and the back was broken, and it has been polished.
local: Quintett, El Dorado co., CA, USA
quartz crystal(partial polish),
length 1.56" width 1.25"x0.8"x0.75"

the rutile is in a radiating bloom that converged about 4" out side ot the quartz.

so anyway this is my favorite of the day.

ynot rock


10th Aug 2013 22:12 BSTGail Spann Manager

Leor, it seems you and I have similar tastes. Your Kutnohorite is exquisite! I happen to enjoy a nice suite of those, from the same location, as well.

By the way, welcome to any and all new posters as well, nice to have you join in on the fun.

We all take great pleasure in seeing other's favorites as well as being able to show off some fun pieces of our own.

10th Aug 2013 23:08 BSTJake Harper Expert

Great to see you posting on mindat, Tony - and nice specimens too. Of coarse, I am particularly fond of your El Dorado Co. specimen!


11th Aug 2013 02:09 BSTBob Harman

HEY EVERYONE !! , Great specimens !! But one small correction for Vincent R. The Clay Center Fluorites are on a matrix of Silurian Dolomitic Limestone (dolostone) and not celestite. I do not see any celestite in his photo. CHEERS.....Bob.

11th Aug 2013 02:38 BSTBob Harman

For reference, one of my several Clay Center, Ohio fluorites with celestites all on the dolostone matrix which can just be seen underlying the bed of celestite. Collected in 2007. CHEERS.....BOB

11th Aug 2013 03:11 BSTTony Charlton

>hey Jake good to here from you!:)-D

>all, i am up to jan. 2013 now and thiers just to much good stuff to name it all!! but i can't wait for some more of the "IBU"s to show up. i guess this favorite of the day could fit that classification. anyhow heres mine.

in 1983 i was introduced to the caretaker of the LILYAMA mine in Piolet Hill and he allowed me to 'hound the property. i found a crystalized quartz vein in the garnite skarn area of the pegmatite that had a hard birth. most of the quartz crystals had been partialy desolved, probably by hot hydro-floric acid solutions, this also removed all of the iron minerals from the vein. at some point in the life of the system some of the remaining crystals were coated by a quartz slag (low grade agite?), and this one specimen recieved a second seeding to become an unique specimen of rose quartz "cactus" crystal.:-)

this crystal is 1 inch tall and 1/2 inch wide at the base.
local: Lilyama mine, Piolet Hill, El Dorado co., California, USA

11th Aug 2013 14:49 BSTGail Spann Manager

A Kutnahorite, the first that I purchased years ago, from our collection. To compliment the one photo'd a few slides above.

12th Aug 2013 05:26 BSTLeor Goldberg

Great piece Gail =). My favorite for today is my thumbnail Tanzanite from Wisconsin. (:-S) :-D

12th Aug 2013 06:05 BSTTony Charlton

Gail -nice kutnahorite, what is it on?

Leor -beuatiful couler on the tanzanite!

my choice for favorite of the day is a quartz crystal var. rose

just so you'all will beleave me on the couler of my last post here is a crystal from the same deposit that did not get "melted" or have secondary growth on it.

this crystal is 1" in length. and it actualy did get a little "melted" in the deposit. (notice the soft edges and deformed tip).

13th Aug 2013 02:18 BSTLeor Goldberg

Thanks Tony =). Where did you get that piece? It's pretty large for rose quartz.

13th Aug 2013 02:32 BSTBarry Miller

Leor - nice Tanzanite. (It would be from Merelani Hills, Tanzania)

(edited to add the word "Hills")

Just having a little fun. :-D

Leor, thanks the rose quartz crystals are from the Lilyama mine, Piolet Hill, El Dorado co., California, USA. they were self collected in the early/mid 1980's. did you notice the "cactus" quartz earlyer on the page? i posted the story behind the find with that crystal.

on another note, i finely cought up with this string. too much good stuff!!!!!!! (never enuff)

well heres my choice for the faverite of the day

this us a microphotografh of chrysacola from the copper mines near Yearington Nevada USA

also self collected. was found in 2004

15th Aug 2013 02:06 BSTTony Charlton

heres my favorite today....

a piece of smithsonite that is banded white and brown with a red serface that has a wonderful luster.

15th Aug 2013 07:53 BSTBruce Cairncross Expert

Hi Gail,

As you like KMF kutnahorite, here are two pics of a 13.2 specimen in my collection of Mn-calcite and kutnahorite together. I took one picture under short wave UV light and it shows the difference between the fluorescent Mn-calcite and non fluorescent kutnahorite. The specimen is from N'Chwaning II mine, Kalahari manganese field, South Africa.



15th Aug 2013 21:17 BSTHerman Du Plessis

Nice specimen Bruce, it just looks wonderful under the UV light!!!


21st Aug 2013 01:47 BSTIan Merkel

Hello all.

I think this is my first post in here! I collected this beautiful quartz and pyrite spray from the Spruce Ridge mine last week. It is complete in almost all ways. 3 small points of attachment on the base is all.

I can't wait to build a little stand for it.

21st Aug 2013 01:52 BSTJonathan Woolley

Congrats, Ian, nice find!

21st Aug 2013 15:15 BSTRob Woodside Manager

Wonderful pyrite specimen Ian;-)

Yes, really beautiful clarity on that quartz. Quartz is under-appreciated due to its commoness. But sometimes they make very beautiful crystals.

23rd Aug 2013 17:10 BSTLeor Goldberg

Galena on a quartz matrix. Some of the quartz appears to be colored green by chlorite. from 9th Septemvri mine, Madan ore field, Rhodope Mts, Smolyan Oblast, Bulgaria. It's better in person.

26th Aug 2013 02:42 BSTAM Mizunaka Expert

Rhodochrosite. South Africa. 2.1 x 2.0 cm is today's favorite.

26th Aug 2013 08:13 BSTStephanie Martin

AM that is a fabulous photo of an unusual rhodo! It rather reminds me of a jellyfish!

Wonderful favourites one and all. I've been enjoying the treats.

I haven't been able to do photos for a while, but thought I would try and steal some shots. I was satisfied with how these turned out so will share my favourite today. This is a pecular growth habit of apophyllite that rather resembles an oddly square rosette. You wouldn't normally think of Wessels Mine as a distinctive apophyllite locale but there you have it.

Apophyllilte (likely Apophyllite-(KOH).

Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa

Overall specimen approx. 3.5 x 2.0 cm, main rosette approx. 1.5 cm

I am really awestruck of the quality of the specimens and the photos in this thread! :-)

This weekend I cataloged a few gadolinite specimens I found some time ago. This specimen became the favorite of the weekend due to it's unusual crystal shape.


3rd Sep 2013 07:45 BSTDon Windeler

This one’s a little off the wall and not a natural mineral, but I can honestly call it a favorite.

This summer I spent several weeks in London on business. While I had the pleasure of revisiting the Natural History Museum, I failed utterly in hunting down any mineral dealers within easy striking distance. (A decade or two back I had visited Gregory, Bottley & Lloyd, but found they had since moved away.)

What I did stumble across was a glass studio on Bermondsey Street with a couple of artists currently taking inspiration from the mineral world. The photo below is of a piece of cold-worked glass my wife and I purchased called “Green Crystal” by Anthony Scala. While the angles are all wrong for a real crystal, I loved how the light caught it from different directions, (ironically) the imperfections within the glass that looked like veils in quartz, and other similarities to a mineral specimen.

My crack at a photograph:

While none of the other works “spoke” to me in the same way as this piece, there was another glassmaker in the studio who currently embeds gold-coated cubes that look like Navajun pyrites into her vases, and another set of stacked purple cubes that made me think of the recent Weisseck fluorites. I’ll generally take nature’s creations myself, but I can certainly appreciate how they inspire others!



5th Sep 2013 15:53 BSTAksel Österlöf Expert

OK, its not my favourite USB stick- but its needed to show the scale.

I think if this Monte Poni phosgenite would be in my collection it definitely would be my favourite at least every third day- or so.

Collection Museum of Natural History (Stockholm) who obtained it from the Italian Mineralogist etcetera Quintino Sella some time ago. I did not measure it, but if the USB is ~55 mm, the specimen itself would be around 60x85 mm and the crystal itself roughly 20x30 mm.

Please enjoy!



6th Sep 2013 13:18 BSTRudolf Hasler Expert

My today's fav. is this Wulfenite twin from Stefanie Mine at Bad Bleiberg which is measuring 5,5cm on edge. It was rescued in the huge pocket with the green Wulfenites in 1986.



7th Sep 2013 05:02 BSTGail Spann Manager

Phillip Simmons and his amazing Halite!

10th Sep 2013 03:26 BSTBrent Lockhart

This is a new acquisition from the recent Mimetite find at the Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico and my favourite of the day.

The specimen dimensions are 10 x 6 x 5 cms.

10th Sep 2013 04:56 BSTLeor Goldberg

Can it be my favorite of the day too? :-S

13th Sep 2013 21:13 BSTAlexander Ringel

Red hot coal!

At least this looks like red hot burning coal. But this piece of burning coal is a awesome Carnelian pebble from Madagascar. Its weight is 265 Gram (a half pound) and the height is 8 centimeters. The Thickness is 3 centimeters.

It is not treated and has still it's natural shape. It has no banding and is nearly uniform. It is so flawless, that it looks artificial. Only a minor crack (1,5 cm x 0,5 cm) near the rim of the backside (not visible on this picture, its on the right side of the top) prevents this piece from being absolutely perfect. A gemstone cut by nature.

16th Sep 2013 07:31 BSTPhilip Perkins

This blue Brazilian Topaz is definately my favourite, top face is 15cm long.

Does anyone know it's locality?

20th Sep 2013 05:16 BSTAM Mizunaka Expert

A neat combination of minerals from the Rist Mine is today's favorite. 6.3 x 5.0 cm.

24th Sep 2013 01:02 BSTNeal Luppescu

Topaz, from the Tribute Pocket, Agnus Dei Claim, El Paso County, Colorado. This etched crystal fragment is interesting in that the faces of the prism are frosted, while the rehealed etched faces roughly parallel to the cleavage plane are glassy and lustrous. There is some color zoning, with the center of the crystal paler than the edges.

8.0 x 3.6 x 5.0 cm

24th Sep 2013 02:58 BSTAdam Kelly

Beautiful piece Neal, It's too bad these are so light sensitive.

I have a small one in my collection, but I like your piece better today. :-D

26th Sep 2013 13:58 BSTVincent Rigatti

I finally got some good photos of this aquamarine by Joe Budd during the Denver show. I have absolutely no photo skills, at least when it comes to minerals. This piece is 3.5 inches wide and 3 inches tall frim Skardu.

15th Oct 2013 17:52 BSTStephen Rose Expert

We didn't collect this zoisite (thulite)-grossular specimen but the association of skarn minerals is striking. We did pick up lots of small axinite specimens from the surface; they are generally abundant at this locality after some good rains. Luning axinite locality, North of Luning, Mineral County, Nevada. October 8, 2013.



27th Oct 2013 13:03 GMTNeal Luppescu

Hi all,

haven´t been on this thread for quite a time. AM a very nice Pöhla baryte ...

Yesterday i got a long time sought after german classic rhodochrosite ... i am really happy with this one:

Rhodochrosite, Bockenrod, Odenwald, Germany. Width 7.3 cm.

Not only my fav of the day but definitely of the month ;-)



18th Nov 2013 16:24 GMTVachik Hairapetian Expert


When you hold this large cabinet piece, you would say just “WOW”. My favorite of the month is such a very high quality piece of snowflake cerussite on the matrix from the Nakhlak mine, in Anarak destrict, central Iran. A group of well-separated stunning colourless/white snowflakes with great luster, all on a contrast colour dolomitic matrix make it unbelievable and extremely rare find from the mine. 15 x 9.7 x 8 cm

19th Nov 2013 09:19 GMTTom V

That's a very impressive cerussite!!!

19th Nov 2013 09:48 GMTAM Mizunaka Expert

Roger, Thanks. Your German rhodochrosite is very nice too. Today's favorite is an odd fluorite on fluorite from Dalnegorsk. 5.2 x 4.1 cm.

20th Nov 2013 10:27 GMTPeter Slootweg

Here is a nice rhodochrosite from Nchwaning that is picked up in Munich for a mere $50.

It is 61 mm high and consider this a "lucky find". Crystals to 6 mm, lustrous and gemmy.

Just like Roger's fine rhodochosite, my favorite of the month!

20th Nov 2013 10:40 GMTRoger Lang Manager

AM, interesting fluo (i confess to be fluorite addict ;-) ... and nice Rhodo too Peter.

Today my fav ist a cerussite from Flux mine, AZ, USA. It is 12 cm wide.



20th Nov 2013 15:37 GMTAndy Lawton

A snapshot of a colour-zoned fluorite from Castleton, Derbyshire, UK. FOV ~ 20 mm

22nd Nov 2013 11:10 GMTVachik Hairapetian Expert


My today favorite is a very rare and nice cabinet piece from carbonate-hosted non-sulphide zinc ore of the Kolah-Darvazeh pit, Shah Kuh Mine collected a few years ago. Amazing bright blue needles of Aurichalcite with white/colourless hemimorphite crystals and white-coloured smithsonite (XRD confirmed) are on brownish dolomitic matrix. What makes this specimen spectacular is mineralogically rich content, in comparison with old time pieces, already on mindat galleries. FOV is 12 cm.

24th Nov 2013 18:22 GMTGerhard Brandstetter Expert

A nice Baryte rosette on Dolomite crystals, dusted with hundrets of small Azurites.

From Shangbao mine, China

26th Nov 2013 16:36 GMTLuiz Alberto Dias Menezes, Fo.

Phil, do you know when your blue topaz was found?; the more likely locality is Virgem da Lapa, that produced blue topaz crystals between 1979 and 1982; on the mid-1990's Teixeirinha mine, Itinga, Minas Gerais produced a small quantity of fine blue topaz (as good as the ones from Virgem da Lapa), then remained closed until the early 2000's when it was reopened and has produced since then several lots of excellent specimens; these are the only 2 localities I know of deep blue topaz in Brazil.

27th Nov 2013 01:03 GMTIan Merkel

Hello Everyone.

This has been my favorite since I was re-united with is about 10 days ago with its base. I collected this specimen in August from the Green Ridge Claims in King County Washington. I collected it while hanging from a cliff on a rope. It is 75 mm and the scepter is terminated on the bottom too! The pocket was small, about the size of a soccer ball. It had about 7 scepters and three dt crystal clusters. There were about 12 other boring points. This is my favorite scepter I have ever found.



27th Nov 2013 04:36 GMTBarry Miller

Ian - gutsy way to collect. I would have admired it from afar.

30th Nov 2013 11:45 GMTSteve Sorrell Expert

It's much more fun unpacking than packing when you move. This one unwrapped today.



30th Nov 2013 23:20 GMTGreg Dainty

Bi-color sapphire crystal, golden yellow and blue, double terminated. 14 x 5 x 3.5mm. Swan Brook via Inverell, NSW. Good definition, transparent sapphire crystals are very uncommon in Australia. The blue triangles make a wonderful pattern. .......Greg

Tarbuttite on pyromorphite Kabwe Mine (Broken Hill Mine), Kabwe District, Central Province, Zambia. 5x4x2.5 cm.



20th Dec 2013 09:14 GMTDale Foster Expert

Todays favourite, a specimen of the alluvial tin worked from beds beneath Restronguet Creek, the lower reach of the Carnon River before it joins the River Fal. This specimen is an old time piece. The deposit was worked by underground methods where shafts were initially sunk onshore and tunnels driven to intersect the tin bearing beds which lie at depth below the river, the onshore shafts were latterly supplemented by iron cased shafts sunk in the middle of the creek with artificial islands constructed around the collars.

The material comprises rounded Cassiterite grains and quartz cemented together by iron oxides, some gold was also found in conjunction with this material, although unfortunately not in this specimen.
