Barite on Malachite
stock #14.1-335
Shangulowe Mine, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
3.7 x 3.1 x 2.1 CM (miniature)
price: $330


A pair of chisel tipped Barite crystals perched on a velvety green Malachite. The Barite crystals have some inclusions of Malachite as well which gives some green color to the milky prism. Classic material from the 1970-80 era, these Barites are unique and are no longer being found. Very good condition and quite attractive, a very unusual association that is a modern classic.
Torbernite
stock #17.1-143
Musonoi Mine, Kolwezi, Western area
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 #18-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.
HOLD Cuprosklodowskite with Kasolite, Sklodowskite etc
stock #HOLD 8.AE-869
Musonoi Mine, Kolwezi, Western area
Katanga (Shaba), Democratic Republic of Congo (Zaire)
5.5 x 4.4 x 4.7 CM (cabinet)
price: $675
Pre Holiday 2017

Perhaps the most beautiful and richly colored U mineral, Cuprosklodowskite from the Musonoi mine is revered by collectors, a "must have" specie. This specimen is quite fine, well crystallized with a dense mass of brilliant green needles protruding from a shallow vug. Several other rare minerals are also present including bright yellow Kasolite in balls and slender crystals. Except for this find in the Congo some decades ago these rare minerals are usually far from esthetic. This specimen is from that older era and quite a bit above average. Now very uncommon on the market in such quality.
