A superb specimen of highly modified rhombohedral Cobaltoan Smithsonite crystals which form smooth, curved crystals to over 2 cm in length. The crystals envelop a core of massive, lead-grey Tennantite which also forms finely disseminated inclusions within the Smithsonite. Due to the inclusion of cobalt and Tennantite, the Smithsonite crystals vary from greyish bubble gum pink to metallic gunmetal-grey. All crystals are dusted with a secondary coating of glassy, colourless Smithsonite crystals of sub 0.5 mm.

Regional guide
Tennantite from Tsumeb, Namibia
Tsumeb tennantite is one of the great paradoxes of the classic mineral world: the species was an abundant ore mineral in the mine, yet sharp, attractive, display-worthy crystals are decidedly uncommon. The best pieces have a sober, gunmetal beauty—steel-gray to charcoal tetrahedra, sometimes frosted or etched, sometimes shimmering under a druse of minute quartz. In the finest examples, the metallic geometry is softened by Tsumeb’s unmistakable secondary-mineral palette: white dolomite, clear to milky quartz, yellow wulfenite, green malachite, mimetite, smithsonite, duftite, zincolivenite, and a remarkable range of arsenates generated from the oxidation of the sulfide ore.
