A vertical rib of massive grey-silver Tennantite forms a central core over which are developed excellent regular tetragonal crystals of sooty-grey Tennantite, typically of between 1 to 1.5 cm on edge. The tetrahedrons exhibit modified edges and are intergrown to form an almost complete coverage of crystals. From the Tsumeb Mine in the Otjikoto Region of Namibia, any remaining gaps between the crystals are infilled with micro Quartz and Pyrite crystals covering the Tennantite core. A terrific example of well crystallised Tennantite from Tsumeb.

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.
