Azurite - crystal rosette form
Hanover #2 Mine, Grant County
2.6 x 1.9 x 1.5 CM (thumbnail)
A perfect and brilliant blue Azurite rosette or flower from the Hanover mine in New Mexiso. Complete all around, with vibrant color, luster and no damage. Ex Larry White collection, this is essentially a single crystal with several smaller crystals that are aligned to create the rose form. There is no point of attachment so this a complete floater, it ranks as a competion grade specimen and I have not seen a better thumbnail from here. These are now very uncommon to find for sale except as old collections are broken up. A small collection number has been painted on a corner of the "back" of the piece, we can remove it if requested. Far better in person the electric color is hard to capture or see on a computer screen. .
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.
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
Denton Mine, Harris Creek Sub District, Hardin County
6.6 x 6.1 x4.8 CM (cabinet)
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.
Seydar, Hoh Nala, Braldu Valley, Skardu district, Baltistan
5.2 x 3.2 x 2.3 CM (cabinet)
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.
Cerussite crystals in several habits with an unknown inclusion that gives a yellow-orange color. The matrix is typically complex and very three-dimensional. Tsumeb Cerussites were found in every imaginable form and sometimes colored by inclusions. This color is very unusual, and we have not seen this before. Under strong magnification the inclusions appear to be fibrous and aligned along the crystal axis. With Tsumeb minerals mysteries are a big part of the fun. The condition of this piece is also remarkable, there is no damage even though the Cerussites are well-exposed and prominent.
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.
A killer quartz "tree" or tangled shrub of slender Quartz crystals with a mint-green color perched on a matrix of large Dolomite crystals. Mined in 2006 at the famed Shangbao Mine, this is a really distinctive display piece. Many of the Quartz are doubly terminated and the condition overall is excellent. Shangbao is justly famous for some of the best Fluorites in the world. However, there were also a few finds over the years of highly esthetic and often odd Quartz. A unique piece that mixes fine quality, good size and display impact.
