Fluorapophyllite with Hubeite
stock #6.2-908
Fengjiashan Wollastonite Mine, Daye
Hubei, China
6.2 x 5 CM (small cabinet/ large miniature)
price: $175


From the type locality for Hubeite, this is an esthetic and unusually pristine apophyllite. Clear crystals to over 2 CM cover the matrix and these are sprinkled with rosettes and clusters of reddish brown Hubeite and some micro calcites. Most of these have lots of serious damage, this one is far better than usual but not perfect. The most important crystals are very clean with only minor edge rubbing seen at 10X magnification, there is some visible damage at the outside edges. This displays well and makes a good addition to a suite of Chinese minerals, rarities or new minerals. There has not been new Hubeite on the mineral market recently.
Wulfenite
stock #8.1-356 GWT
Tuokexun (Toksun) Tulufan Prefecture
Xinjiang, Uygur region, China
4.2 x 3.4 CM (miniature)
price: $400


A very different, pretty and unusual style of Wulfenite from the finds in Xinjiang of 2007. This is the only piece I have seen of this Wulfenite that has a chocolate brown to greenish color on one side of the crystals and a dark red-brown on the other side. Sparkling and delicate this small miniature has many crystals without damage. The largest reach 1.6 CM and have a beveled edge termination. The darker color and glassy luster reminds me of Magma mine Barites. For any Chinese suite or Wulfenite collection this is special, its not like any other Wulfenite produced here!
Manganite w. Barite
stock #8.1-421
Ilfeld, Nordhausen, Harz Mts
Thuringia, Germany
5.2 x 3.4 CM (miniature)
price: $380


From the most famous and classic locality for Manganite this is a very attractive recent specimen excavated from an adit discovered on an old dump dating to the 1500s. Much Manganite in collections can have several hundred years of history as the Harz Mts have produced the best materials centuries ago. This find produced a small number of good pieces some with very bright luster. Thius is a good example with excellent contrast with the calcite that has been partially etched away. This is also far more affordable than the vintage materials when they can be found!
Fluorite with Dolomite and Manganocalcite
stock #6.2-122
Chashan Mine, Linwu Co., Chenzhou Pref.
Hunan Province, 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 Zhuang Autonomous Region, 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!
