Description

An over 0.6 Kg specimen with tens of grey crystallized crystals of tennantite intergrown with white crystallized quartz, also at the rear of the piece. Most tennantite crystals have curved faces, with a black reaction coating, typical for Tsumeb, with the tetrahedron {111} as the dominant form, and edges modified by the cube {100}. There are also some nice tabular wulfenite crystals of a cognac colour.

Already a classic, it was acquired in 1988. Ex Jan Soudan sample, it has been was in my own collection since 2012.
