Three steely blue-grey, razor-sharp tetragonal crystals of Tennantite sit on a tiny matrix of micro-crystalline brassy-golden Pyrite from Tsumeb. One Tennantite crystal dominates, measuring 2.2 cm tall with edges to about 2.4 cm; the two much smaller crystals interpenetrate at its base. The crystals have a metallic lustre with subtle shades of steely-blue highlighting development growth in the triangular faces. A great Tennantite from Tsumeb and most aesthetic in its sharpness of habit.
