I’ve had this specimen in my collection from my early years (1990’s) and I have many better, so time to let this one fly. One of the most prized combinations from Tsumeb. The largest rhomd is 1.5cm. Ex Geoff Krasnov collection. Locality: Tsumeb Mine, Otjikoto Region, Tsumeb Namibia Composition: calcium carbonate and copper cyclosilicate
