Cuprian Smithsonite on Dolomite
Miniature, 4.4 x 4.0 x 3.0 cm
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Ex. James and Marjorie Ferguson
This specimen features a very rare style of cuprian smithsonite, such that I believe it was only found in one pocket (early 1980s?). The style is defined by isolated, gemmy, sharp crystals as you see in the closeup, to 8 mm in size. Usually, cuprian smithsonite from here is rhombohedral or a simple druse but these are more elongated and look more prismatic in habit. However, these are real, euhedral crystals of superb quality. A rich druse of glistening, sugary microcrystals contrasting against the dolomite matrix completes the visual appeal here! I have seen only one other of this type for sale recently, and that from the Sussman collection and at a much higher price for comparable quality (though the piece was larger, too)
