A well-known yet rare pseudomorph of bladed Azurite completely replaced by metallic dark grey Tennantite, the largest replaced crystal measuring to 2.5 cm long. This excellent example of Tennantite pseudomorphing after Azurite is from the Tsumeb mine in the Oshikoto Region of Namibia. Under low magnification the pseudomorph is seen to be composed of micro-granular Tennantite with a fine sucrosic texture which forms sharply defined crystals replacing former Azurite. A terrific pseudomorph from the famous Tsumeb mine.

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.
