Choice, quite lustrous green Pyromorphite (originally labeled as Mimetite) from the old locality at Donori, Sardinia. Very good coverage and deep apple green color, a few small crude crystals are seen with strong magnification, but overall this is a botryoidal specimen. Quite three dimensional and in fine condition, this is much richer than most I have seen from the locality. These are now often labelled as being Pyromorphite- Mimetites as it seems there are both species in the deposit and may be zoned.
Goshenite & Fluorite on Schorl
Erongo Mountain, Karibib
4.2 x 3.3 x 3 CM (miniature)
Worldwide mix summer
A fine miniature from the Erongo that features a gem clear Goshenite Beryl perched atop a cluster of purple Fluorite that is offset with lustrous black Schorl. In excellent condition the front display side is in perfect shape, the base area is contacted. Few of this find were so distinctive. Choice, esthetic and well balanced.
Fluorite on Sphalerite
Elmwood Mine, Carthage
14.9 x 9.8 x 5.3 CM (cabinet)
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.
stock #SOLD 7AE-036
Daoping Lead-Zinc Mine, Yangshao
Guangxi Autonomous Region,
8.8 x 7.3 x 4 CM (cabinet)
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.
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.
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
7.6 x 6.2 x 3.4 CM (cabinet)
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.
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.
