ONLY FROM TSUMEB! This is a very unusual combination of mineral species, at Tsumeb or anywhere to my knowledge. Crudely formed copper crystals with a fine patina frame many intergrown crystals of lustrous and translucent, gemmy smithsonite, to 1 cm across. Several of the sharp smithsonite rhombohedra are included by copper, something I have not seen before in this habit. Copper is actually quite rare at Tsumeb, in native form.
