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 Calcite

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.
Cobaltoan Calcite
stock #A-24-588
Aghbar Mine,Bou Azzer District, Tazenakht, Quarzazate Province
Ouarzazate Province, Morocco
6.6 x 4.5 x 4.1 CM (cabinet)
price: $700
Pre Holiday 2017

A very bright color rounded knob that is also covered with rounded crystals of rich magenta-purple Co Calcite. The back and botton are the attachment points where this was broken from the bedrock but the display surface (front, top and sides) is in perfect condition and very impressive. The individual crystals have a bright wet-look luster and many are also two toned making a very eyecatching display. This locale has now been flooded and we do not expect to see the produced again. A future classic with the unique color that makes the best of these so desirable. Choice.
Cobaltoan Calcite (scalenohedral and hollow crystals)
stock #12.1-254
Bou Azzer District, Tazenakht, Ouarzazate Province
Souss Massa Draa Region, Morocco
6 x 4.8 CM (cabinet)
price: $850
Spring 2014

A really esthetic example from the great find of 2012 which was the best in nearly 20 years. This find had many average pieces but very few that were fine. These are now unavailable in this quality and condition. Great color and fine form, these scalenohedral crystals are in some cases hoppered or hollowed cavernous spikes in a radiating cluster. Some damage is noted mostly on the outer edges, but the central main display area is pristine.
Cobaltoan Calcite
stock #13-1-002
Agoudal Mine, Bou Azzer
Souss-Massa-Draa region, Ouarzazate Province, Tazenakht, Morocco
6 x 4.7 CM (cabinet)
price: $950
Spring 2013

A especially choice piece from the best find of Cobaltian Calcites in Morocco in almost 20 years! This is a striking, fine and really well formed "flower". Composed of scalenohedral and hoppered scalenohedral crystals up to 2 CM long this has an electric intense pink color that is easily noticed in any lighting. A great impact specimen, it reminds me of a N'chwaning Rhodochrosite but with a cobaltian color. In very good condition overall, the only notable damage is at the outer edges, the main central crystals are excellent.
