Cuprite with Native Silver
Rubtsovsky Mine, Rubtsovshy District
4.6 x 4.6 x 4 CM (miniature)
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.
Danburite and Datolite
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region,
3.4 x 2.1 x 1.8 CM (miniature)
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.
A flat habit rhombohedral crystal of Rhodochrosite sits aesthetically on matrix. Tiny purple Fluorite and Pyrite is also on the front face of the Rhodo adding some character. The matrix has clusters of elongated white Apatites (not visible in the photos) mostly on the backside. These are vividly fluorescent (yellow) in long wave. The condition is excellent and the Rhodo is partly transparent. Better color than is usually seen, this piece was from the earliest finds of Rhodochrosite at Wudong. I do not think any Apatites were found in the later pockets.
Mefis, Taouz, Errachidia Province
4.3 x 3.3 x 1.2 CM (miniature)
Glassy and transparent, a thick tabular habit Barite with inclusions. This find a few years ago produced some large crystals that were mostly milky and somewhat crude. We obtained a few that were more sharp, defined and clear though smaller than average from the find. These sold quickly but we have this piece back via a collection purchase. This is one of the best.
Dioptase on Shattuckite
3.8 x 2.7 x 2 CM (miniature)
Bright blue shell of Shattuckite hosts dozens of emerald-green Dioptase crystals. In perfect condition, the color and form are excellent and better in person. A choice miniature the back side is a hollow cast with the shape of Quartz crystals, thought the front is the pretty part. Quite a lot of the Kaokoveld Dioptase is a little dull but this has the desirable glass-like luster.
Elmwood Mine, Carthage
4.4 x 2.7 x 2.3 CM (miniature)
An esthetic miniature specimen ex Larry White collection. The purple phantom cubes contrast well with the light colored matrix. The Fluorites also have a sharp exterior ridge-line frame on the outside of the cubes that adds some extra interesting geometry. Nice miniature from the great Elmwood Mine that is quite different from the usual mine run. All of the Fluorites are transparent, the matrix also has a druse of tiny colorless cubes as well. Elmwood was one of the last world class specimen mines in the USA and is certainly a modern classic locale.
The Payun Volcano is a very unusual locality and the Hematites from this area are unusual too. This piece is a stack of octahedral crystals that had been Magnetites but are pseudomorphed to Hematite and are now coated with small sparkling Hematite crystals (Specularite type). On some of the octahedral faces it is easy to see the red Hematite crystal surface below the black sparkling crystals. The sculptural form of this miniature piece is quite elegant and there is no damage. This find of Hematites seems to be finished, they will rank as exceptional and are destined to be considered as classics.
Wulfenite with Mimetite
Mina Ojuela, Mapimi
4.7 x 3.8 x 2.2 CM (miniature)
Elongated orange Wulfenites crystals free standing on a mixed matrix of Mimentite and gossan. From the epic discoveries in 2017 at Mina Ojuela, this sweet miniature has fine color, luster and is in excellent condition. This was a large find and produced a lot of specimens but few small pieces presented this well.
