Fluorite on Sphalerite
stock #8.1-273
Elmwood Mine, Carthage
Tennessee, United States
14.9 x 9.8 x 5.3 CM (cabinet)
price: $750
Worldwide mix summer

A larger cabinet specimen of a modern American classic. Two zoned purple to white cubes sit on opposite sides of a lustrous Sphalerite matrix. A few small Dolomite crystals add a nice accent as well. In very good condition and quite esthetic, the backside is contacted but not seen from display side. The cubes are 5.7 CM across diagonally.
Pyromorphite
stock #7AE-036
Daoping Lead-Zinc Mine, Yangshao
Guangxi Zhuang Autonomous Region, 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.
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 Province, 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.
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.
Azurite -Spherical with Malachite
stock #13.1-416
Morenci Mine, Copper Mt. District, Shannon Mts., Greenlee County
Arizona, United States
8.6 x 5.9 x 3.8 CM (cabinet)
price: $900
Spring update

Brilliant blue ball form Azurites sit on a contrasting gossan matrix with a few areas of Malachite. Choice old specimen ex Warren Johannson collection. Warrens notes give the locality as Bisbee and he obtained it in 1937. It is very likely from nearby Morenci as this habit is noted there, and many Morenci pieces ended up with Bisbee labels. Some additional balls are on the backside, but the display side shown is the best for presentation. The soft matrix has been stabilized, the luster is very bright and the color electric blue.
Malachite Slice of stalactitic nodule
stock #18.1-218
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
5.4 x 4.5 x .5 CM (small cabinet/ large miniature)
price: $380
Spring update

Sharp and colorful pattern is well presented on both sides of this cross section of Malachite. Good polish and fine contrast in the banding that is "cauliflower" in form. This sort of quality slice was at one time more common but now is quite scarce. A modern classic.
