Pyromorphite
stock #7AE-036
Daoping Lead-Zinc Mine, Yangshao
Guangxi, China
8.8 x 7.3 x 4 CM (cabinet)
price: $875
Spring update

Large mass of pure Pyromorphite in 3 dimensional hills with good grass green color. From the Daoping mine near Yangshao, this was mined before 2005 in the upper oxidized zone. That area has now been finished and the mine is closed. Well covered on the face with dense crystals, nearly all are perfect a few chips can be found with careful looking, but obviously not very noticable. The price reflects this. The luster is mixed, some crystals are quite bright and others have a more matte look. A good rich, sizable Pyromorphite from an important mine.
Andradite with Quartz
stock #15.1-487
Huanggang Mine, Chifeng Prefecture
Inner Mongolia Region, China
3.9 x 3.7 x 2.7 CM (miniature)
price: $130
Spring update

Dark brown to almost black, very lustrous and sharp, a cluster of Andradite Garnet with a small doubly terminated Quartz. From the prolific Huangang mines in Inner Mongolia.
Dioptase- Large crystal
stock #11.1-39W
Tsumeb
Otjikoto Region, Namibia
4.7 x 4.2 x 2.3 CM (miniature)
price: $480
Spring update

A large main Dioptase crystal is the focal point of this Tsumeb piece. At 2.2 CM across this is well over average size and has top glasslike luster. The backside has contacts and there are a few small edge bruises, this is reflected in the price, but the main view is in good condition with brilliant color. Classic Dioptase like this from Tsumeb are unlike specimens from other locales, this has that deep emerald color and is translucent. Ex Kraus collection.
Pyrite Pseudo after Marcasite with Dolomite
stock #0170-JM-2630
Nanisivik Mine, Nanisivik, Baffin Island
Nunavut Territory, Canada
8.7 x 6.1 x 4.8 CM (cabinet)
price: $250
Spring update

Golden, sharp and brilliant, Pyrites have fully replaced Marcasite crystals and these are well clustered on a series of large Dolomite crystals. Older specimen, ex John Marshall collection, obtained in 1991, there is no sign of instability or other problems as can happen with Pyrite pseudomorphs. A few crystals do have edge chips but most are perfect and complete. Attractive example with textbook twinned crystals from an very interesting, remote location.
Calcite -Pineapple habit, on Quartz with Fluorite and Dolomite
stock #5.1-074.3
Shangbao Pyrite Mine, Leiyang
Hunan, China
8.3 x 5.3 x 3.8 CM (cabinet)
price: $280


The distinctive "pineapple" style Calcite from Shangbao came out sporadically in the 2000-2008 era, this is a very choice example of the habit. Set on a matrix of sparkling Quartz the addition of a few scattered purple Fluorites adds extra contrast. In fine condition as seen, the terminations of the Calcites are transparent and the body of the prism is more milky, all with the "pineapple color". Top Shangbao Fluorites are now regarded as some of the worlds best (and most expensive). 15 years ago at the mine the Calcites were more expensive from the miners than Fluorites because they were more rare and hard to extract intact. Times change.
Stibnite- tabular crystals
stock #7.AE-290B
Cavnic (Kapnic)
Maramures, Romania
7.6 x 6.2 x 3.4 CM (cabinet)
price: $330
Spring update

Choice old Cavnic Stibnite with the rare type of flattened crystals. Sharp and clean, fine metallic luster and very three dimensional. These mines are closed and specimens of this quality are not often available. Even more impressive in person.
Fluorite- water clear green cubes
stock #6.2-767
Xianghuapu Mine, Linwu, Chenzhou District
Hunan, China
8.4 x 6.3 x 4 CM (cabinet)
price: $775
Spring update

From the finds at Xianghuapu in 2006, a super sharp and fully transparent cluster of Fluorite with bright luster. We obtained this back then at the mine, we selected from thousands of pieces looking for top quality and this was of that calibre. We sold all those specimens long ago but this one is back and it is nothing like the average pieces that flooded out later on. Now that the mining is closed up this sort of specimen is quite treasured. In fine condition, you can read through the Fluorites, which makes them difficult to photograph well enough to be fully appreciated. The main cube is 5.5 CM diagonal and is like green glass.
Smithsonite Pseudomorph after Dolomite
stock #15.1-583
Rush Creek, Marion Co.
Arkansas, United States
10.2 x 6.7 x 3.7 CM (cabinet)
price: $300
Spring update

The classic habit of saddle shape Dolomite crystals completely replaced by sparkling smithsonite. The matrix is also nearly all Smithsonite and mostly composed of the rare red-orange color but also has zones of the more typical yellow. A long running debate concerns the color being caused by either Cadmium or Greenockite inclusions. To me it is a distinction without a difference, Greenockite is simply Cadmium Sulfide and so that Cadmium is ultimately the source for the color. In good condition, only a few very minor abrasions can be seen, the Dolomite saddles are quite large and stand well above the matrix.
