Cuprite with Malachite
stock #20.1-318-(LW494)
Kambove
Haut-Katanga Province, Democratic Republic of Congo (Zaire)
2.4 x 2.3 x 1.3 CM (thumbnail)
price: $90


A cluster of dark red Cuprite crystals with tufts of fibrous Malachite. Some minor contacting on the back but the front and sides are quite fine with no visible damage. The Cuprites are translucent and if backlit will glow to a bright cherry-red. A nice thumbnail from a modern classic locality.
Diamond - cubo-octahedral crystal
stock #20.1-317-(LW394)
Miba Mine, Mbuji Mayi
Kasai-Oriental Province, Democratic Republic of Congo (Zaire)
.6 x.6 x .5 CM (thumbnail)
price: $350


A nice bit of Carbon. Perfectly formed, complete Diamond crystal 2.25 carats showing textbook habit. The color is a green-yellow and the faces shows microscopic stepping and hundreds of small crystal faces. Ex Larry White thumbnail collection, obtained from Stachura Minerals in 1968. The Miba Mine dates back to 1913; it was a Belgian operation for many decades becoming one of the world's largest producers. In the early 60's more than half of the entire worlds supply of Diamonds came from this one site.
Cornetite - crystallized, with minor Malachite
stock #20.1-142
L Etoile du Congo Mine (Star of the Congo), Lubumbashi
Haut-Katanga Province, Democratic Republic of Congo (Zaire)
10.8 x 6.3 x 5.2 CM (cabinet)
price: $330


A sparkling vivid blue specimen from the famed "sparkle pocket" found decades ago. The piece is well-mineralized on both sides but only one side has the rich lustrous sparkles. The specimen is sawn on one side and this cut is visible from most display angles. Despite that saw mark the specimen is a very rich example of what was perhaps the best find ever for the specie.
Dioptase
stock #12.1-017
Tantara Mine, Shinkolobwe, Kambove District
Haut-Katanga Province, Democratic Republic of Congo (Zaire)
3.3 x 2.8 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $240


Emerald green and glassy Dioptase crystals in a very nice cluster from the Tantara Mine (Katanga). The largest crystal is just under 2 CM, there is no matrix just pure Dioptase in very good condition as seen. The Dioptase from Congo does not have the ultra bright luster of a fine Tsumeb specimen but can be a bit brighter than many from Kaokoveldt. This piece is of that sort, better in person and quite esthetic. Congo Dioptase is not often available, it seems to be found every decade or so in small batches and then there are none for years. This was mined in 2012.
Cobaltoan Calcite with Malachite
stock #20.1-269
Kolwezi, Katanga Copper Crescent
Lualaba Province, Democratic Republic of Congo (Zaire)
4 x 3.7 x 3.5 CM (small miniature)
price: $90


A small, colorful and cute specimen from the Katanga Crescent (not the more common Moroccan type). There are two separate vugs on this piece with brightly sparkling purple-pink crystals and a few sprays of green Malachite adding contrast. Some bruising on edges is noted but still a pretty and affordable small piece.
Barite on Malachite
stock #14.1-335
Shangulowe Mine, Kambove District
Lualaba Province, 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
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.
