Fluorite on Sphalerite
stock #15.1-515
Elmwood Mine, Carthage
Tennessee, United States
5.3 x 4.3 x 3 CM (cabinet)
price: $175


A sharp single Fluorite perched on a complexly crystallized Sphalerite matrix. The Fluorite is transparent, and has geometrically etched, stepped structures on its faces. The front or display side is in perfect condition, a tiny cleave is noted on the back side that is almost invisible by naked eye. The Fluorite is like a small jewel, the color is purple blue. There are still some good values to be found in Elmwood Fluorites.

Cuprite with Native Silver
stock #10.1-086
Rubtsovsky Mine, Rubtsovshy District
Altaiskii Krai, Russia
4.6 x 4.6 x 4 CM (miniature)
price: $780


Just over a decade ago the incredible discovery of fantastic large Cuprites from Rubstovsky (Russia) was huge news in the mineral world. This is an especially choice example of a fine undamaged Cuprite with the addition of having Native Silver on some areas. Even without the Silver this is a super Cuprite, it has excellent form and luster, is in fine condition and with good lighting the inner red colors are seen on some edges and faces. This piece was found in the early discoveries, it is of a style and quality that is no longer coming out (the find may have been exhausted but there are still some coming from dealers storage). The bright luster makes this hard to show well in photos, it is far better in person and very fine for the discovery.

Topaz - classic Russian, on Feldspar, Quartz
stock #16.1-597
Murzinka Mine,Sarapulka Dist., Sverdlovskaya Oblast, Middle Urals
Urals Region, Russia
5.4 x 3.2 x 3 CM (small cabinet/large miniature)
price: $560


A 2.5 CM tall gem clear colorless Topaz crystal rises above the contrasting Matrix. The Topaz is undamaged, in impeccable condition, the matrix has some bruising but it is the matrix and not at all a detriment. A very nice composition over all, good Topaz from the Urals is something of a mineralogical prize and highly respected by collectors. A very good value for the quality and esthetics.

Fluorite with Chalcopyrite
stock #13.1-123
Denton Mine, Harris Creek Sub District, Hardin County
Illinois, United States
6.6 x 6.1 x4.8 CM (cabinet)
price: $620


Dark purple-blue Fluorite that is zoned with yellow to orange cores that are best seen with a backlighting. Some faces are dusted with tiny Chalcopyrite crystals and most faces have a lustrous pattern of geometric regrowths. A few edges show modification patterns but most are sharp edged. The Denton Mine is a now one of the great classic localities for USA Fluorite, good specimens are getting very scarce and quite expensive. This is a nice example that is rather dark without backlight but really comes alive with a light behind it.

Quartz - red acicular form
stock #12.1-252
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region, Russia
6.7 x 5.2 x 2.6 CM (cabinet)
price: $290


The Russian red Quartz from Dalnegorsk is unique in the mineral world. These slender, tapering crystals tend to be darker red at the base and a lighter orange to colorless at the tips. This piece shows the habit and color very well. Minimal matrix and despite some tip cleaves the overall condition is better than most of these delicate sprays.

Grossular
stock #7.AE-315
Seydar, Hoh Nala, Braldu Valley, Skardu district, Baltistan
Gilgit-Baltistan, Pakistan
5.2 x 3.2 x 2.3 CM (cabinet)
price: $620


Dark red-brown clusters of Grossular Garnets that are partly transparent and have minimal matrix. In very good condition, some of the Garnets have contacts or internal cracks that reflect light and in photos look like damage. Crystallized all around from a find at Seydar in the Braldu Valley, this is a not well documented locality.

Acanthite
stock #18-AX-22-175
San Juan de Rayas Mine - Level 407
Guanajuato, Mexico
2.2 x 1.3 x .6 CM (thumbnail)
price: $140


Branching crystals of Acanthite forming a tree-like thumbnail with very bright metallic luster. Complete all around, undamaged and pretty. A very good yet still affordable Silver specie from the famed Guanajuato deposit. This area has been continuously mined for Silver since the discovery in 1585, and this was the world's largest producer for many years. Amazingly there are still a few operating mines and Silver minerals are still found though far less than before.

Danburite and Datolite
stock #14.1-214
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region, Russia
3.4 x 2.1 x 1.8 CM (miniature)
price: $325


Gemmy light blue Datolite crystals clustered on a gemmy colorless Danburite crystal. The Danburite has some small etched zones that show re-crystallization, but overall this is a sharp prism. From Dalnegorsk, this is a choice miniature of these two species that looks fine from practically any angle. Our background for this specimen does not specify which part of the mining complex was the source for this piece but it seems certain to be from the Bor Pit. No damage; esthetic and unusual.
