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.
SOLD Carrollite
stock #SOLD 17.1-750
Kambove
Katanga (Shaba), Democratic Republic of Congo (Zaire)
4.2 x 3.2 x 3.2 CM (miniature)
price: $0
Pre Holiday 2017

A very big, sharp and lustrous fine Carrolite single crystal. Far beyond the average in quality, this is a killer example. Contacted on the backside where it was attached but in perfect condition on the front. The faces are mirror bright and shows subtle growth structures. The Kambove mine was by far the best source of Carrollite in the world. Particularly fine crystal for the size and clean condition, the form is textbook sharp and impressive.
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.
Cuprosklodowskite with Kasolite, Sklodowskite etc
stock #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.
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.
