A UNIQUE and BIZARRE Tsumeb specimen consisting of white, poker chip calcite stalactites preferentially capped by malachite. A totally uncommon and unusual occurrence, obviously from a large, cave-like vug! The lustrous calcites are stacked multitudes of tiny flattened rhombs. This unique piece is complete all-around and is essentially pristine, with only a few broken stalactites on the periphery. Ex. Rob Smith Collection.
