Mineral PhotographyBest photographs of specimens larger than 1cm

28th Mar 2013 11:11 GMTRudolf Hasler Expert

When scrolling through Mindat's photo galleries I can see lots of excellent photographs of micro mounts but not very many of larger specimens.

The reason for this might be that people who specialize on micro photos are mostly real experts while photographs of larger specimens (measuring at least 1cm) are usually made by collectors like myself who are more interested in collecting than in photographing.

With this thread I want to invite all collectors to show her/his best photographs of specimens larger than 1cm. Everybody can show his own favorites side by side. These photos can be exchanged whenever somebody thinks she/he has new better ones.

The result might be a very nice collection if many follow my example. Please, don't let me stand alone with my pictures!

Jesus, Ronnie, you're kicking ass and taking names! Sick howlite.

3rd Apr 2013 02:19 BSTRonnie Van Dommelen Expert

Thanks guys. They represent a LOT of field trips though. And I only helped collect two of them.

Tim - yes that is a unique howlite. We've never found one so well exposed before.

What I don't understand is why more people haven't added their best pics. I was really looking forward to this thread growing quickly.

3rd Apr 2013 10:22 BSTSimone Citon Expert

...because it's easy to talk about, but it is not easy to do!

Hello all !

Nice pictures indeed !

But... a question : do you use a stacking software (Helicon Focus, Combine Z, Zerene...) ?

Best regards


19th May 2013 10:04 BSTRudolf Hasler Expert

Hello Jean-Marie,

I think that most of us are using stacking softwares.

Best regards,

Those are very good pictures and very fine specimens. These two attributed often do not go together in our image gallery, but here they do. They will be good additions to our best minerals articles.

26th May 2013 19:52 BSTRonald J. Pellar Expert

A 37mm Stak Nala Pakistan tourmaline.

26th May 2013 22:11 BSTRock Currier Expert


That's a good picture. On my monitor however the black in the crystals, especially on the left side seems to make the left side of the crystal disappear into the background. I took the picture into Photoshop and increased the dynamic range of the image, or lightened the shadows as they call it and the result is below.

I think it looks a lot better. Knowing how careful with color and light and your background as a color scientist I have to assume that the image you downloaded did not look like it appears on my monitor. My recent work on some of the Best Minerals articles, especially all those black schorl specimens makes me think that perhaps most images that are uploaded to mindat have their dynamic range downgraded automatically by the upload process and it might be a good idea to develop an algorithm to automatically increase the dynamic range of uploaded images when needed if that would be possible.

I would be interested in your thoughts on the matter.

26th May 2013 22:37 BSTRonald J. Pellar Expert

Hi, Rock,

Playing in Photoshop can change a lot of things in an image, some for the better. Your manipulation is OK but the uploaded image is a JPEG and any manipulation of JPEGs can actually make it worse. An automatic enhancement as you suggest would not be good for a lot of the images. The enhancement that you did may look better to you, but it is not very representative of the specimen itself. Its kind of un-natural. The dynamic range in the original specimen as I look at under normal lighting is closer to what I have uploaded.


27th May 2013 01:46 BSTRock Currier Expert

So the picture you took didn't show a distinct edge to the crystal of tourmaline?

Your monitor may not be displaying the full dynamic range of the image. Those $129 monitors from Costco don’t make it. A man of your means can surely afford a good one. :-D I think Ron has it right on. The left edge is just barely perceptible on my photo editing monitors, so the full range of dark to light is nicely reproduced. I find the photo to be very pleasing. Nice shot Ron!


27th May 2013 03:57 BSTPaul Brandes Manager

The original photo looks fine as it was posted on my monitor with no fading to black as you saw, Rock. In all honesty, the photo after you Photoshop'ed it looks unnatural now, as though there is too much light on the subject or it was overexposed when the photo was taken. The only slight knock I have on the original photo is that to me it is still too shiny with the light reflecting back off the specimen, but that's just me.

27th May 2013 06:29 BSTRobert Brandstetter Expert


27th May 2013 10:46 BSTRock Currier Expert

Even my secretary has a better monitor than a $129 Cosco special.

27th May 2013 20:02 BSTRonald J. Pellar Expert


Maybe you would like this version better?

Or would you prefer a different color? :-D

27th May 2013 21:24 BSTRonald J. Pellar Expert


Manipulation of images is as old as photography. I remember before the digital age when I used dodging paddles to selectively adjust the exposure in certain areas of a photo. Some people took the adjustments too far and the result was more art than documentation. For minerals I think documentation is far more important than art and photoshopping should be restricted to improving the presentation without introducing any kind of distortion of reality concerning the specimen itself. Change the backgrounds all you want but try to present the mineral image honestly and as realistically as possible. I feel that "edge sharpening", e.g., "unsharp masking", "sharpen edges", etc., "shadow" and/or "highlight" adjustment, "color correction", etc. is sometimes overused to the point of making the mineral look "unnatural" even though the image is very impressive. Don't get me wrong some sharpening is definitely an improvement, it is only when carried a little beyond that it becomes too much.

Because of camera metamerism, white imbalance, etc., some "color correction" may be necessary, but if your monitor is not properly setup with a decent color profile, you could do more harm than good. It might look good on your monitor after your corrections but not on anyone else's monitor.

I am totally against any automatic processing by MinDat on upload (other than scaling of size). Let the photographer and/or uploader be responsible for their own photos. Any auto processing exposes MinDat to all sorts of complaints, criticism, etc. and should be avoided at all costs.


27th May 2013 22:28 BSTHarjo Neutkens Manager

There are lots that I could count amongst my favourites, but I'll limit myself to just two.

Isolated pale milky blue, double terminated CELESTINE, 5.8 cm x 3.8 cm on fossiliferous dolostone. Self-collected in August 2008 in Lime City Quarry, Ohio.

Groups of small milky quartz crystals sprinkled over a 6 cm calcite and very minor reddish dolomites. Large, 14 cm

4th Apr 2014 00:32 BSTBob Harman

BARITE in the American Midwest is found in a variety of circumstances. In the Michigan copper country, it is found very sparingly. It is common and quite collectible in the Illinois Kentucky fluorite area as it is in the Elmwood Tennessee mining area. In Midwest quarries, perhaps the best crystals come from the recent finds in Iowa. There are many small and localized sites where it can also be found. In the sedimentary geodes of the Midwest, it is common, but, by far, the best and largest BARITE crystals are found in the geodes of south-central Indiana.This geode, from Monroe County, Indiana collected in the 1980s, is 14 cm x 9 cm and contains a single stout 5 cm x 3.8 cm x 0.9 cm thick crystal. Tiny marcasite and/or smythite crystals are included into the barite; this is quite common. CHEERS……BOB
Whereas I normally photograph micro-mounts, Sharon has had me photographing some of her thumbnail collection recently. So, for me, these are gigantic specimens (they do exceed 1 cm) and present their own problems in photographing them. Of course, she had to provide me with a decent macro lens in order to start the project. :-)

I have a lots of pictures taken before the Stacking got popular and many of those are already posted in my albums on Facebook and elsewhere. Pictures posted here are so good that they show all information about the specimen so fast that it is overwhelming and kind of shocking.

Now my question is; Should I go and re do all my photos or do my old photos provide the enough visual information about the specimens.

Anyone that has the time please look at some examples here;

Part of this was taken with 4MP Nikon Coolpix 4500 and part with the Olympus C 8080. I still use both this Cameras despite the Nikon D90 that is sitting here unused.

6th Apr 2014 19:17 BSTRudolf Hasler Expert


I had a quick look at some of your pictures in facebook and I wish all my pictures were as good as yours. There is no need in my opinion to redo them. If I were you I only would take new pictures of those that I am not content with. That is what I often do with my older pics.

Great Idea, but I have to agree with Maggie - the bar has been set very high (and I'm a photographer!) :-)

Impressive photos folks!

I will search my "archives" and hopefully find some pics that compare.



17th Aug 2014 22:41 BSTRudolf Hasler Expert

Hi Frank,

Thank you for your appreciation.

I am convinced that you can find many pictures that fit in here and I am looking forward to see them.

18th Aug 2014 07:12 BSTRudolf Hasler Expert


Frank, you should upload the pictures to mindat's database first. Then you can easily use them here just by clicking on the red tourmalin icon and filling in the mindat numbers of your pictures.



18th Aug 2014 22:54 BSTFrank Craig

Thanks Rudolf, i'll do that. Here are a few more in the interim.

18th Aug 2014 23:20 BSTRob Woodside Manager

Frank, There's a Photo of the Day (POTD) on the front page and photographers are quite competitive for it. Managers select POTD candidates and everyday one candidate is randomly chosen. Occasionally Jolyon will go in a set a photo for Hallowe'en or April Fools, etc., but there would be an uproar about favouritism if there was any meddling. I'm telling you this because the quality of your photos is certainly adequate for a POTD, but the managers tend not to select photos with writing on them. I look forward to your uploads.

No Frank I don't think there's any format other than to avoid writing on the image. The other thing that does appeal to managers is some kind of mineral info pertaining to the photo in the caption. So an excellent photo of something uncommon has a much better chance of POTD if the caption has a mineralogically interesting story rather than just a species name. I hope that helps.

Great pix everyone!

Speaking of large crystals, here is a pic from the Palermo pegmatite mine in New Hampshire of my wife Sheila with the remnants of a huge microcline that was exposed in the quartz core. This photo was taken in the 1990s, cant remember exactly what year, but the year before, my first trip there ever, this was an intact, euhedral crystal, the biggest I had ever seen, in a museum or in the field! (Hard to see the remnants just past each hand, the termination at upper left is more obvious). And I didnt have a camera!! So, sadly by the next year they had blasted most of it away and I got only the remnants...(this is a poor scan of a print, one day I'll make a better one and post it to the locality page).
Always bring a camera when collecting, there is only one opportunity to photograph minerals in-situ.

Your photography no longer simply astounds me. It is beyond imagining. Wonderful amethyst.

Question on the top reflective face. What are the small regular geometric gray appearing images. Surface features, or a view into the crystal, or ??? Very interesting and intriguing

Thanks for your continued day brighteners

Hi Jim,

Thanks for your nice comments. I am glad you like the piece. It really is quite a glassy jewel. The geometric forms in the reflection are surface features.

23rd Oct 2014 20:43 BSTRonald J. Pellar Expert

When photos are uploaded and are not the correct size for display purposes, Mindat uses an interpolation algorithm to resize them. There are many of these algorithms that are designed for different purposes and some of them will cause a slight blurring. In general, good results are obtained with a "nearest neighbor" algorithm for sharpness issues. Some people resize their photos so that Mindat does not have to resize them and they will get better results.

Last week was the yearly show at Liege, Belgium. Nice show with a lot of good stuff for decent prices.

Among others I picked up a topaz from Itinga, Brazil. Two shades of blue and with typical etching for this location.

Measures 4 by 3 by 3 centimeter.

The first picture has a black, reflective background.

The second picture is taken with a metallic, reflective background which always leads to creative colour effects.

This little plate of azurite on malachite is from Bisbee, Arizona and measures about 12 x 8 cm. Photo, with questionable focus, taken through display case glass at the W.M. Keck Museum at the University of Nevada, Reno. I have to say that following AM at any time is problematical, and after that wonderful photo of hemimorphite with malachite it seems more so. :-)

Hi all,

Stephen, you are right about AM's pictures. I think nobody can get close to him in his pictures AND specimens.

On another topic on Mindat he is doing well too.

You probably noticed that another topic about " high end specimens " is going on for the moment. See here :,6,341350,341479#msg-341479

AM, every specimen you show is in my eyes a high end specimen combined with a high end picture.

Keep on the good work and thank you very much for sharing them with us.

No Bob, I'm not positive. This is a purchase from an estate. Some of the labels were confused or missing.

DENNIS I really think it more likely that your fluorite specimen is from the Minerva, Annabelle Lee, or Denton mines in the Illinois - Kentucky fluorite district rather than the Elmwood mining district in Tennessee. But let's see what others think.

I suggest putting your pix into the identification/locality thread and asking others their opinions. CHEERS……..BOB

Quartz from Nöchling, Lower Austria.

20th Dec 2014 01:11 GMTStephen Rose Expert

This specimen of nicceline is somewhat crude but is of an unusually large partial crystal with additional, smaller crystals on the back. It is from Eisleben, Thuringia, Germany and measures 5x3.5x3.5 cm.

The first picture shows three faces of a large, hexagonal dipyramid while the two additional photos show more numerous, complete, conical crystal terminations up to about 1 cm across their base.

This would have been one of my favourite images were it not for the two bits of fluff spoiling it. 52 image stack of goethite from Wheal Drea, St. Just in Penwith, Cornwall. I have a can of compressed air for blowing out specimens afore imaging, I just need to use it more often :-S

Well done there many strings to your bow :)-D

I gave up on the idea of purchasing Elements after getting absolutely nowhere with a very basic 'photo manipulation program. Spent almost a whole day on the damned thing and all I could manage in the end was to create text on an image!

As I said, I must use the air spray before each and every image taking session so it becomes part of the many images have been 'binned' due to unwanted 'pubes' and 'bogies' spoiling the shot ;-)

14th Jun 2015 10:25 BSTOwen Melfyn Lewis

Thanks for pointing that out. Can't imagine how it occurred - but definitely at my end :-(

Found it - and definitely not at my end :-)

Grabbing the image from the forum results in it being transmitted by Mindat as marginally less that VGA standard (640x480 pixel). My small manipulation was of the .jpg file as sent from Mindat - a fraction of the standard of the standard of Jay's image on the forum (itself subject to the 1Mb limit on photo file sizes for publication on the forum.

Accordingly, the file I uploaded back to the forum was the same quality as that made available by Mindat ;-)

14th Jun 2015 15:04 BSTMatt Courville

Fantastic work! I especially appreciate the AM Mizunaka quartz from Pakistan a little back in this this post. I've found that some quartz are of the most difficult to get a nice image due to the way that light tends to pass through or reflect off of them. Hope to see more on this post, and I will throw-in a curve ball with some SW/LW UV light photo requests;)

This one has an interesting self collected story. It comes from an 1880's railroad bed near Fairbank Arizona, where old overburden from the early Bisbee mines was used to build the rail bed. The material came from near the old Holbrook Mine area of Bisbee. Not bad for lying in the ground for about 125 years.

This is a Bisbee Azurite we got at the Tucson show a couple of years ago. The interesting part was that it was purchased at a German dealers room. It had been over in Germany and we bought it. It was an old piece and since we live not too far from Bisbee, my wife took it along on a trip to Bisbee to visit our friend who runs the Bisbee mine tour. Mary's reason for taking it along was to complete the mineral specimens journey full circle coming from the Copper Queen at one time and now going back home again, at least for a visit.

The wonderful thing was turning the piece over and seeing the wonderful malachite on the opposite side.

Love seeing all the great minerals specimens people show on this thread.

To those wulfenite photographers out there, can you give a novice some tips? I have a 4.5cm x 3.5cm specimen bought from Hummingbird Minerals of brown-orange, intergrown wulfenite crystals (with some calcite) from Mexico. I've been playing around with diffusion filters and various lights and reflectors (both matte and shiny) to properly illuminate it and have trouble getting specific crystal faces lit without getting burn-outs or flares in other faces or getting others in shadows. I've pretty much decreased the overall brightness and increased the shutter speed. Thanks in advance.

12th Mar 2017 11:19 GMTAntoine Barthélemy

I would be interested in reading answers to your questions Isobel, because I often encounter the same problems as yours. It is just by trying and trying again that I can (partly) solve them.

Anyway, here is a Touissit azurite with nice transparency.

12th Mar 2017 17:40 GMTRudolf Hasler Expert

Hello Isobel and Antoine,

I am only an amateur so I also cannot really tell you something that might solve all our problems. Just as you both said it is a matter of trying and trying to light the numerous faces of Wulfenite specimens. Sometimes I use up to eight lamps in different positions. I also use different diffusion filters to take out the burn outs. But all these efforts do not guarantee a really satisfying result. It always is a kind of challenge for me that does make photographing very interesting.

I'm sorry to criticise you in the light of the recent discussion about your gold specimens Jon, but I don't feel your photos fit all that well in this particular topic. It was started to showcase high quality photography of larger specimens; in other words, it's not necessarily the specimens themselves that are the stars of the show here, but rather the photographic techniques to accurately and aesthetically capture the beauty of minerals. Your photo is far too blurry and low-res to even make out any of the different minerals that are supposed to be present, let alone any detail in them. Besides it looks like you used software to edit the blue colour into the photo, but you accidentally applied it to certain areas of the specimen as well. I know it is a matter of personal taste, but I also feel the background is too bright and distracting.

Again, I don't mean to be too harsh, but I feel this topic should have a fairly high standard of quality - after all, that's what it was started for so that we can all admire the beautiful photography here on Mindat and learn from each other. For me, the photos of AM Mizunaka, Antoine Barthélemy and so many others inspired me to continuously experiment with the lighting, composition, image processing, sharpening and so many other aspects that combine to produce a mineral photo. I genuinely hope it will inspire you too, your gold specimens are of a quality that deserves so much better photos, so they will look just as exciting on our computer screens on the other side of the world as they do when you hold them in your hand over in Nevada.

14th Aug 2018 21:23 BSTJon Aurich

Hi Niels, you are right, the pictures are blurry when focused to. The photos weren’t enhanced, I just have the specimens in a blue bowl... The thread does say best pictures, so I will respect that, the other thread that you spoke of was a whirl wind of conversation, although I was supported by the founder of Mindat on what I was doing on the other thread. Anyway, have a good day, and I will probably look into something better to take Pictures rather than my camera phone...

14th Aug 2018 21:49 BSTRuss Rizzo Expert


A digital camera would be a huge improvement for you. Even a refurbished older one. All of the photos that I've posted on Mindat were taken with a 4.0 megapixel Canon G3 Powershot that I bought in 2003. I recently bought a refurbished one from for $99 so that I would have a spare. Stay away from eBay when buying used cameras.

The newer low-mid price range,16, 20, whatever megapixel cameras do not impress me. The end product usually comes out looking like some of the lower quality cell phone pictures that you see posted here. I've bought and returned so many I can't count them all. Unless you are going to spend $1,000 plus for a camera & at least that much on lenses, a refurbished version of the one I mentioned is a good place to start.

I do recommend getting a tripod too.

You'll find that you will need to do some color, brightness/contrast correction & sharpening to your photos. There are websites out there where you can get older versions of PhotoShop at a deep discount. You just need to make sure whatever version you get is compatible with your computer's operating system.

That's about all the advice I have to offer. There are many other members that are much better photographers than I am. I'm sure that they have much advice and wisdom that they will be happy to share with you.

I'm just starting out photographing and cataloging my collection. I'm pretty happy with this one as a first attempt. I'm used to outdoor available light portrait and nature photography with little experience with indoor and macro photography. It is definitely a learning experience. So far the only modification I've made to any of my photos has been tweaking contrast a little. I welcome feedback.

15th Aug 2018 17:20 BSTGreg Simmons

PS.. I have not experimented with focus stacking yet. It's on my list but I want to be more comfortable with getting my lighting right first. I have two other images of that specimen located with that one.

15th Aug 2018 17:52 BSTMatt Courville

Great shots Greg! You chose a tough 1st mineral with the varied matrices and focus points. Personally I find that I need at least 2+ light sources and a few options on diffusing the light to make it work well for most minerals. Minerals on calcite always drives me nuts! Good luck

15th Aug 2018 18:03 BSTGreg Simmons

Thanks Matt,

For those shots I used a light box I made using white foam core and vellum. There is a top light and one on each side that are diffused through the vellum, plus I have a photo/video light at the front near the camera that is variable brightness. After taking a bunch photos I discovered that the best shots were ones where I eliminated one of the side lights. I appreciate you taking a look.

15th Aug 2018 18:31 BSTHiro Inukai

I've mentioned this in another thread, but if there is a single photographic technique that has made the biggest impact on my images, it would be focus stacking. Over all else, it has made a huge difference, especially when magnification exceeds 1:1. It's tedious to do, and it creates a huge amount of source data, but the results are undeniably superior to single shots of my micromounts and thumbnails. It has really helped me to convey the beauty of these tiny specimens--when my friends see the photos, they marvel at the color and fine structure of these minerals, and then are even more amazed when I show them that it all came from some tiny, unremarkable-looking rock. That's why I love to photograph micros, because they are like treasures whose secrets are revealed only if you look closely enough.

But since this is a thread about bigger specimens...who cares about focus stacking! LOL

Just kidding. Here's a photo where I used focus stacking to good effect. Otherwise, it would not have been possible to get all of the crocoite crystals in focus. Locality is the Dundas mine, Tasmania, Australia. Specimen is approximately 6 cm in the longest dimension, and it's one of my favorite miniatures for the clean and aesthetic crystal formation.

15th Aug 2018 18:50 BSTKevin Conroy

Since this is a larger specimen, if you don't want to photo stack you can experiment with depth of field. The larger the f-stop the greater the depth of field. However, this also effects the amount of light entering the camera, as well as the overall sharpness of the photo. Play with it and see if the results are to your liking.

15th Aug 2018 19:06 BSTGreg Simmons

Thanks Hiro and Kevin,

I do think that photo stacking will come into play when I photograph closer in to highlight details. I'm definitely working on my depth of field and then zooming in digitally to best frame the specimen. Here is another calcite I did.

I'm not 100% happy with the images. I think on the one that shows the whole piece I should have increased the f-stop and maybe would have gotten better depth of focus. (I should have dusted off the black surface in front of it too. LOL #rookiemistake )The other two images are just digital zooms of the first one. They are ok but I would like to have had better detail that showed the crystal tufts more vividly.

NOTE: I'm using 27mm-135mm lens so not a true macro lens.

15th Aug 2018 20:20 BSTHiro Inukai

Hi Greg,

That's a good photo of the calcite specimen. I can also see that you are aware of the ways in which you could improve on the image.

With respect to achieving a sufficient depth of field, stopping down can only achieve so much, especially when the subject magnification is high; moreover, the effects of diffraction at very small numeric apertures (i.e., high effective f-number) robs the image of sharpness even in the plane of sharpest focus--hence the need for focus stacking. Also, a small aperture lets in less light and requires compensating by either increasing subject illumination, exposure duration, or sensor gain (ISO).

My rule of thumb is that between 1:2 and 1:1, f/8 - f/11 is the maximum tolerable f-number; up to 2:1, f/5.6 - f/6.3; up to 3:1, f/5; and up to 5:1, f/2.8 - f/4. There are tables out there with more precise ranges.

The cheapest but not necessarily most aesthetic way to deal with shallow depth of field (after stopping down) is to reorient the subject so that as much of the details you wish to capture is situated parallel to the image plane; in other words, if you want the tufts of white calcite as well as the older generation of brown calcite to be in focus, is to position the specimen so that it is directly facing the camera.

It is something of a misconception to think that focus stacking requires a motorized rail and specialized stacking software. While these greatly facilitate "deep" stacks with a lot of source images at high magnification, there is much room for compromise here. Some of my best stacks involved only 2 or 3 images, shot handheld without the assistance of a rail, and merged manually. And if you have a tripod, that can help keep the framing constant as you adjust focus. Also, keep in mind that not every part of the subject needs to be in focus, but when you choose what portions you wish to have sharp, it is usually (but not always) best to have foreground features sharp and background features out of focus.

One thing I've noticed about a lot of the photos I've seen here is that many of you like to show the entire specimen (unless it's a micromount). This is something I need to get used to, since as someone who is not a mineralogist, my aesthetic criteria are different from most of yours. I realize you want to show the specimen in context, and that this is an important consideration. I need to work on this, I think, if I am to document my collection properly.

One other comment I do have is with the quality of lighting. I recommend trying to keep a consistent color temperature across all of your illumination sources, since diffuse natural lighting tends to be cooler than indoor incandescent light. Bringing the light physically closer to the specimen can dramatically increase the intensity of illumination, although it also may change its character (diffuse versus specular, etc). Lots to think about!

17th Aug 2018 05:50 BSTGreg Simmons

Thanks Hiro. That's a lot of good info. I just added this halite to my catalogue. Take a look. I experimented with lighting some more as well as depth of field so more of it appears in focus.

15th Sep 2018 20:35 BSTAntoine Barthélemy

I started playing with my new camera this afternoon :-)

15th Sep 2018 20:55 BSTAntoine Barthélemy

And by the way, thanks Hiro for your explanations, I learned something about the relation between aperture and sharpness.

Greg, you're on the right path with your pictures. If I may give you an advice, it would be to lower the ISO to reduce the noise, which is especially bothering (well, slightly bothering ;-) ) in your first calcite pictures.

17th Sep 2018 00:44 BSTGreg Simmons

Maybe this is a silly question but.. what is the noise you are referring to? What element in the image is considered noise?

Thanks for the tip.

21st Sep 2018 12:46 BSTFrank K. Mazdab Manager

Thought I'd take a stab at this forum, and maybe kill two birds with one stone (ha ha). This is a cerussite on corroded galena I picked up a few years ago from one of the Moroccan "tent" dealers at the Arizona Mineral & Fossil Show. The long dimension is 7 cm. The photography was pretty unsophisticated, especially compared to what others are doing here. I took this simply with my iPhone SE, with daylight illumination, and with the phone supported on a box about 10 cm from the sample (the closest I could get and still focus). Afterwards I cropped out the edge of the box, and using Mac's Preview program, I did an auto levels adjustment and applied sharpening. The photography isn't going to win any awards, but if the only camera you have is on your phone, I think it's still possible to take decent (record-keeping worthy) photos. So this is my personal subjectively "best photo of a specimen over 1 cm".

The other "bird to kill" here is that unfortunately the dealer simply labeled the specimen's locality as "Morocco", without including, or perhaps even knowing, a more precise location. My feeling from looking through all the Moroccan cerussite photos here is that it's probably from the Touissit district, since it doesn't look like any of the Mibladen examples. I suppose it could also be from one of the lesser known localities. Normally I'd be reluctant to buy a poorly-labeled specimen, but this puppy was just $15 so I couldn't pass it up. It'd be great to be able to include at least a district (even if I have to follow it with a question mark), so if any Moroccan-cerussite experts have an opinion, I'm all ears.

23rd Sep 2018 19:50 BSTAntoine Barthélemy

I don't know if I am an expert, but I like Morocco and cerussite ;) The way the crystals are twinned reminds me of Taouz. You could check the cerussite picturess from there to see if they match.

Hi Johan,

thank you for the additional input! Yes, in fact the galena matrix is so corroded it's almost unrecognizable as galena... it's very fine-grained and surprisingly dull; had the material not had cm-sized cerussite crystals growing on it, I probably would have mistaken the unimpressive vuggy gray mass for some artificial smelter reject.
