Tennantite
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.
