Fluorite with Dolomite and Manganocalcite
stock #6.2-122
Chashan Mine, Linwu Co., Chenzhou Pref.
Hunan, China
8 x 7 CM (cabinet)
price: $280


It has been several years since any specimens have come from the Chasen Mine, I hear it is fully flooded now. This is a fine example of the quality the mine was capable of producing. A sizable (4 CM) gemmy Fluorite has a rim of epitaxial Dolomite crystals making a "nest" along two edges. This sits on sprays of Mangano calcite that are dusted with micro pyrites. Only very minor chipping that is not distracting, and nice FL as well. There is a little similarity to the material from the nearby Xinghuapu Mine, but the differences are distinctive. Suitable in any collection but especialy good for Fluorite suites or Chinese collections.
Adularia (manebach twin)
stock #6.3-915
Cavradi, Tavetsch, Grissons
, Switzerland
10.9 x 4.1 CM (cabinet)
price: $250


A wonderfully esthetic example of Swiss Adularia, a well defined Manebach twin set on a slender shard of matrix. Excellent condition, sawn on the back to remove this without damage. You don't need to be a Feldspar collector to appreciate the setting of this twin!
Native Silver w. minor copper
stock #8 US 941
Wolverine Mine, Wolverine, Houghton Co.
Michigan, United States
12.2 x 5.2 x 1 CM (cabinet)
price: $940


A very large and rich Silver from the Wolverine mine. This has almost 100 percent Silver but there is a tiny sploch of Copper on one edge. The silver has a patina ranging from near black to irridescent to brighter silver tones. Some of the silver at first glance looks copperlike. Some bits of matrix are included but this is nearly all metal. With low magnification some herringbone and crude crystals are seen as well. In outstanding condition this is a classic and heavy chunk of Michigan Silver!
Copper -Flattened spinel twins in branching array
stock #AC-097
Central Mine, Keweenaw Co.
Michigan, United States
6.8 x 5.1 CM (cabinet)
price: $300


A very fine copper branch, well crystallized and with great esthetics. This piece still has a few flecks of adhering matrix (which could be removed). The definition and sharpness of the flattened crystals is outstanding. It is hard to tell what the vintage of this is, but this is clearly a very old piece, sold by Shortmanns in the 1950s but perhaps over 50 years older than that. There is a lot of good copper in the market but this is really different and distinctive!
Rhodochrosite with Native Silver
stock #8.1-419
Wudong mine, Liubao, Cangwu Co. Wuzoh
Guangxi, China
4.1 x 3.8 CM (miniature)
price: $1650


A big rich red translucent rhomb that is quite a good Rhodo on its own. However, this has the addition of wire silver and silver "skins" in several spots. The largest wire is about 7mm long and easily visible. This locality has produced only a few good examples of this rare association. This is an outstanding one. The crystal is transparent to translucent and glows with any backlighting. There is the typical internal stress fractures visible inside, a contact on the backside, and cleaving on the exterior as seen in the photos. Despite this it is a very attractive, displayable, bright and eyecatching crystal in the top percentile of quality from this location. A most desirable piece for a Chinese suite, Rhodo or Silver collection or just for the novelty and color!
Kunzite (Spodumene)
stock #7 PAK-007
Chitral, Chitral Valley
North West Frontier Province, Pakistan
4.4 x 3 CM (miniature)
price: $150


A sharp, attractive Kunzite with an unusual form caused by two parellel crystals with staggered terminations. Deep color, fine luster, and a more "prismatic" look than most Spodumene. Some slight edge wear is visible but it is very minor, not distracting to this nice gem crystal.
Tourmaline (elbaite)
stock #8 PAK-743
Paprock, Konar
Nuristan, Afganistan
4.6 x 3.5 CM (miniature)
price: $280


Attractive and sharp miniature presenting 2 terminated pale pink to clear (achroite) tourmaline posed esthetically on matrix. No damage is visible to the naked eye, a very tiny chip is found under 10X magnification. The bigger crystal is 3.1 CM long. A very good value for such a clean and pretty specimen.
Bixbyite
stock #8 UT THUMB 788
Thomas Mountains
Utah, United States
2.9 x 2.7 CM (thumbnail)
price: $75


A lusterous thumbnail with several sizable and sharp bixbyites, on a matrix of topaz (cystallized with "sand" inclusions). The crystals all have some contacting and included topaz and the matrix topaz is somewhat crude. Despite this the largest crystal of Bixbyite is sizable at 1.4 CM and very bright, and this is well over the average in general quality.
