A complete Geode of Carbonate rock filled with colorless Selenite needles and brown to pinkish spheres of Kutnahorite. In perfect condition, this is from an very unusual occurrence and is a very attractive presentation of Kutnahorite unlike any others we know of. This specie is a fairly uncommon Manganese Carbonate, but it can take many forms and habits. It is best known as good display specimens from the Kalahari Manganese Fields, from most other localities these are quite drab. This deposit has a very different style and esthetic, the better specimens like this are quite attractive and unusual. This specimen is especially rich for this locality with balls of Kutnahorite to well over 1 cm both pink and brown in color.

Classic Native Copper tree-like form with a colorful patina is perched on a shard of matrix. In fine condition with some slight iridescence in strong light, this is a an older piece with three previous collection labels included. This is from a less well-known locality at this former serpentine Quarry. The Copper crystals are distinct though crude, flattened and elongated having grown in a narrow seam. Some adhering Serpentine and Chrysocolla add a nice accent.
A remarkable and rare habit of Fluorite, this from the Orange River area of South Africa. The larger Fluorite crystals on this specimen are hexagonal stacks of flat crystals which on close examination are seen to be flattened spinel twins with small square edge windows. A second generation of bright yellow Fluorite is encrusting some edges of the blue to purple large Fluorites. Such unusual forms and habits make Fluorite an incredibly diverse example of the cubic crystal system. These are also prized as exotics by Fluorite collectors. In excellent condition on the front and sides, the back is both contacted and partly cleaved which is not visible from the display side. Especially for those who enjoy strange crystal habits this is a choice and attractive specimen.

A super esthetic specimen from a remarkable find almost 15 years ago at Xikuangshan. This has a delicate transparent Calcite crystal perched on edge that is shot through with metallic Stibnite crystals most of which extend outside of the Calcite. This look great on all sides and the Calcite (3.7 CM across) is well-formed, complete and in fine condition. The black sparkling matrix is a very nice contrast to the metallic Stibnite and the Calcite. This specimen was in the collection of Michel Jouty, and is especially well-composed with a fine architecture.

A fine, well-crystalized specimen of this rare Lead Copper Iron Sulfide. The world's best specimens came from this remote Kazakhstan locality in 1998, this is one of those. This is a cluster of striated, metallic to sooty black crystals, on what looks like a matrix that is also Betekhtinite in crystals of a different habit. Very choice for this rare specie that is not often available. A great find for those who love rare sulfides and find black minerals to be especially beautiful!
An especially fine thumbnail of elongated Chalcocite crystals some showing the cogs-wheel form of twinning.

This style is quite uncommon from the mine and presents well from all sides. In excellent condition with well-defined form and esthetic composition.
