Description
Tennantite is a mineral species with crystals that are generally intergrown or clustered, however, in this exceptional Tsumeb piece, beautiful individual tetrahedrons up to 1.6 cm on edge grace a matrix of very delicate pink Dolomite rhombohedrons. The ore mineral is matt black with a dull metallic luster, and partly coated with tiny sparkling Dolomite crystals. A top specimen for the species from Tsumeb!
