Howdy All,
I'm just a crazy collector from the land down under!
And a student of Geology at University.
Member of the Mineralogical Society of South Australia, Adelaide Gem and Mineral Club and Murraylands Gem and Mineral Club. Formally holding committee positions with all these groups.

I have a major interest in historic mines and mineral locations of South Australia.
I'm slowly trying to update the South Australian locality's on here and add new ones.

My goal is to have all those that actually produced specimens on here, while leaving out all of the
'we were only looking out back to see if there was something there' type of listings.
Not as easy as it might seem, the S.A. government, has at times given out 'incentives' to those who might find new mineral wealth here. So there are many listings in the Mines Records that are no more than a little prospect at the back of a property, purely to gain money from the government of the day!
Still there are many more that are the real thing!

If you have questions about SA don't hesitate to ask, if I don't have the answer, I probably know someone who does!

Q3G-D49Proustite : Ag3AsS3

Schneeberg District, Erzgebirge, Saxony, Germany

Dimensions: 2.7 cm x 1.2 cm x 1.2 cm

2.7 x 1.2 x 1.2 cm. This large thumbnail is a stunning, display-quality piece with a 2 cm gem proustite, perched on a natural pedestal of proustite. The major crystals are not only gemmy and deep red, but they are pristine. The piece is complete-all-around, and displays nicely from either side. With even the most minimal backlighting, you can see its ruby-red transparency. What I love about this most, as a competition-level thumbnail, is that the crystal habit is so distinct there is no thought that this is a Chanarcillo proustite. The habit here is distinctive, and seldom seen in such quality. Although likely a very old specimen, it has been preserved well. Ex. Will Larson Collection.

0QE-PUMQuartz (Var: Smoky Quartz) : SiO2, Microcline (Var: Amazonite) : KAlSi3O8

Florissant Area, Teller Co., Colorado, USA

Dimensions: 12.7 cm x 7 cm x 6.2 cm

12.7 x 7.0 x 6.2 cm. Firstly, this specimen is not repaired as so many of these classic combinations are, today on the market. Also, it is from the older classic locale in Florissant, and is not the relatively more plentiful new stuff from the contemporary Smoky Hawk claims. It is probably 1960s-1970s vintage, but no way to tell for sure now. The specimen has all the qualities you would want in a combination from here: great color amazonite; great color smoky quartz; translucence to the quartz; and overall good aesthetics. And, it has no repairs. It is pristine and undamaged. At 5 inches across, it’s of good size, too. Ex. Steve Neely Collection, with label.

Y82-4RMQuartz (Var: Amethyst) : SiO2

Amatitlán, Mun. de Zumpango del Rio, Guerrero, Mexico

Dimensions: 18.3 cm x 6.5 cm x 4.7 cm

18.3 x 6.5 x 4.7 cm. This is an outstanding, glassy and gemmy cluster of amethyst from this famous and very sparsely producing locale. It has deep purple, grape-juice colored amethyst cores, grading to a clear zone at the very tips. The display face you can look right down into, as the glassy, transparent surfaces facing front let you look deep within. It is nearly pristine. Although larger amethyst crystals occur elsewhere, for my tastes the combination of the color and qualities in great Guerrero material make them the world's best of species. This is an excellent example of why I say that. It is from the Marc Weill Collection, but would have been most likely mined in the 1970s or 1980s.

T5W-5WJBeryl (Var: Aquamarine) : Be3Al2Si6O18, Albite : NaAlSi3O8

Shigar Valley, Skardu District, Baltistan, Gilgit-Baltistan, Pakistan

Dimensions: 10.1 cm x 8.4 cm x 7.2 cm

10.1 x 8.4 x 7.2 cm. This is a dramatic piece for its unique 3-dimensional display qualities. The two aquamarines splay out from the central, curving cluster of sharp albite crystals. They have a porcelain look to them and contrast sharply with the gem aquamarines. This is not repaired, which is amazing given its exposed crystals. The large crystal is approximately 8 cm long sticking out from the core (though it is longer, and goes through the albite cluster to their base. The smaller crystal is 8 cm long, of which 5.5 cm sticks out freestanding. Direct from the mines to me, this was mined in 2008.

2TU-HLWSpodumene (Var: Kunzite) : LiAlSi2O6

Laghman Province, Afghanistan

Dimensions: 12.5 cm x 7.4 cm x 2.2 cm

12.5 x 7.4 x 2.2 cm. This is a superbly sharp, unusually well-terminated crystal of about 370 grams, from the classic occurrence here. It is a floater, complete on the bottom, and looks equally fine from either side. For its size, it has robust color and also is completely gemmy and transparent. Dallas-area collector Wally Mann bought this from Herb Obodda after one of his trips to Pakistan in the early 2000s and treasured it not just because it was fine; but also because it really could (and did) fool a lot of people, with its color and sharp form, into thinking that it was a turn-of-the-1900s piece from Pala, San Diego. But it was too big in size for his collection, as a whole, and so did not fit.

RUL-1ATFluorite : CaF2, K Feldspar (Var: Adularia) : KAlSi3O8

Aiguille Verte, Mont Blanc Massif, Chamonix, Haute-Savoie, Rhône-Alpes, France

Dimensions: 6 cm x 4 cm x 4.3 cm

6.0 x 4.0 x 4.3 cm. This specimen from the new pocket found in 2007 at these Alpine heights, is of intense color for a pink fluorite, almost red. It is a superb, balanced piece with several combined octahedrons forming a 4.5 x 4.5 x 4 cm cluster on a bit of adularia matrix. The fluorite is complete-all-around and nearly pristine. This pocket will stand on its own merits, as one of the great Alpine finds, I believe. Few specimens in this size range had such good balance, free of clunky matrix but also complete-all-around.
