Druse of dioptase crystals, with very defined faces and edges, brilliant, transparent, and disposed on a quartz rocky matrix. The color is very distinctive, difficult to reproduce in photography. They are accompanied by small aggregates of malachite crystals, with a different green. A piece of good size and quality.

Malachite specimens from this Upper Katanga mine are notable for radial aggregates of fine crystals that, taken together, have a velvety appearance and excellent brilliance. Intense green colour, good size and fine aesthetics.

Malachite polished section on both sides. We offer this type of product not simply for decorative purposes, but also from an educational and scientific perspective. The section allows us to see the concentric growth structures of these malachites.

Small orange to yellow kasolite crystals, very aesthetic under magnification. They are disposed on a sandstone matrix with malachite. A Musonoi classic.

A very aesthetic specimen composed of very lustrous, dark green primary malachite crystals. The crystals have a triangular to rhombohedral appearance due to the way they have intergrown and are brighter green at the edges. It is quite rare to find primary malachite crystals, especially with well-defined crystals, and this mine is known for producing these malachites. The specimen was labeled "libethenite" (sic), and of course we analyzed it (analysis RM308), although a drop of HCl would have ruled out the phosphate, but...

Malachite specimens from this mine typically appear without matrix. This specimen shows a botryoidal aggregate of intense green color arranged very airily on a quartz matrix. Very aesthetic.

These specimens come from the type locality for kolwezite, a copper-cobalt carbonate. Most of the "kolwezite" pieces seen on the market don't have the 1:1 Cu:Co ratio required to call them that; they usually have a 2:1 Cu:Co ratio. Of all the ones I've analyzed (and there are quite a few), even the olive-green ones maintain this ratio. In this case, we can say, to be honest, they're cobalt-rich malachite specimens. Even so, the specimens are very aesthetically pleasing. If I ever find a 1:1 Cu:Co kolwezite, I'll probably find the grail...

Highly aesthetic botryoidal malachite aggregates completely covered by a layer of slightly greenish-blue chrysocolla. We can see the malachite, with concentric growths, in some fractures. The beauty of these specimens makes them worthy of the finest collection and display case.

Carrollite is a copper cobalt sulfide, with the very finest of the species coming from the DR Congo. This excellent specimen is sharp, well-defined, and has a bright metallic luster. The single crystal is a modified cuboctahedron and accompanied by chalcopyrite crystals in calcite matrix. It has small nicks due to mechanical work to make the crystal appear that do not affect aesthetics. The condition and aesthetics both help make this such a choice display sample.
