Torbernite
stock #17.1-143
Musonoi Mine, Kolwezi
Katanga (Shaba), Democratic Republic of Congo (Zaire)
8 x 4.3 x 2.8 CM (cabinet)
price: $1650
Spring 2019

A big well crystallized plate of deep green Torbernite from the old finds at Musonoi. In fine condition, with individual crystals averaging over a Centimeter (up to 1.5CM). These top Congo specimens are from finds decades ago, these are already considered to be classics for the specie. Most of the crystals here are standing on edge with termination faces showing but a few are laying flat. The flat faces have a lighter green color and are a nice contrast to those showing darker edges.
Chrysocolla PS after Malachite after Azurite
stock #15.1-330
Lupoto mine, Lubumbashi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
9.1 x 8.1 x 5.9 CM (cabinet)
price: $780
Dec 2018

An eye-catching complex cluster of very sharp crystal forms that show clearly the original shape of the Azurite crystals that were altered to Malachite and are now nearly all Chrysocolla. A few of the smaller crystals have broken section that show the core of unaltered Malachite. Other crystals are now hollow as well, reaching up to 3.2 CM long. Overall this is a delicate specimen that is very 3 dimensional and a choice cast form . One of the mineralogical discoveries that made big news about 2 years ago, these are now quite scarce on the market.
Cobaltoan Calcite and Malachite
stock #AX-12-019
Mashamba West Mine, Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
6 x 4.4 x 4.2 CM (cabinet)
price: $640
Dec 2018

The Cobaltoan Calcites of Mashamba have been gone for more than a decade now, but they are still considered to be some of the best and most intensely colored ever found. This specimen has the most desirable contrast with a small matrix of green Malachite and has several generations of pink to clear Calcite displayed. Sadly there are some edge cleaves or contacts but the overall specimen condition is very good and still displays well. The best Scalenohedral crystals are remarkably clean and free of chipping. There are several possible display angles. Now very hard to get in the mineral market these are unique and quite sought after.
Cobaltoan Dolomite with Calcite and Malachite
stock #18.1-436
Mashamba West Mine, Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
6.3 x 3.8 x 2.8 CM (cabinet)
price: $550
Late Summer 2018

The intense color of a good Cobaltoan Dolomite is unlike any other, unique in the mineral world. This specimen has top intense color, and the crystals are unusually well formed, some in tabular habit to 1.1 CM. In excellent condition as seen, this is an older piece collected years ago. Sawn on the back the front side is an open elongated vug that has protected the crystals well. Small dark green Malachite crystals are a nice color contrast. Super display esthetics and electric bright color jump out in any array of minerals.
Cuprite with Malachite, Plancheite etc.
stock #17.1-702
Mashamba West Mine, Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
5.8 x 3.7 x 3.4 CM (cabinet)
price: $460
Pre Holiday 2017

Big, dark red and lustrous Cuprite Octahedrons are nestled in light blue Plancheite and dark green Malachite. Fine contrast, esthetics and in very good condition. The backside is contacted but not damaged, pitting and face voids are natural some with Plancheite inside. Individual octahedrons are up to 1.8 CM, some with nice edge modifications quite rare at this locale. These have not been coming out for almost a decade. Choice.
Cobaltoan Calcite
stock #16.1-002
Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
6.3 x 5.8 x 3.2 CM (cabinet)
price: $280
Pre Holiday 2017

Colorful bright specimen with rhombs to 2.4 CM, ex Victor Yount collection. In fine condition, at one edge the overgrowth of Cobaltoan Calcite has not covered the underlying Calcite rhombs and the structure is well exposed.
Chrysocolla Ps after Malachite (after Azurite)
stock #15.1-329
Lupoto mine, Lubumbashi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
8.3 x 6 x 3.9 CM (cabinet)
price: $380
new june 17

Really fine form and rich color on this specimen from the recent finds at Luputo. The pseudomorph retains the shape of the original Azurite crystals that were rep[laced by Malachite and finally replaced by the blue Chrysocolla. The delicate array of crystals is on a Gossan matrix and in excellent condition despite the fragility. The discovery of this material made big news in the mineral world. This is a choice example with particularly distinct crystal shapes well presented.
Barite - Included by Malachite
stock #AX-19-258
Likasi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
5.1 X 5 X 4 CM (miniature)
price: $520
Spring 2017

Clear Barite crystals with some blebs and wisps of bright green Malachite inside and on the prisms. from the great Shaba Crescent area, this is a nice example. As is typical for this locale, magnification shows several bruises but most of the main crystals are in reasonable clean condition. Though not right for a perfectionist, this is still a good display specimen and these are no longer coming out from the Congo.
