Calcite (Rob Smith Coll.)

Item Description

Very glassy, highly lustrous, calcite rhombs including with an unknown oxide form a very showy and excellent specimen from the famous and now-closed Tsumeb Mine. The splendent, mirror-like faces really light up in good light! We believe the included material to be goethite, but have not had it analysed. Ex Rob Smith Collection. MUCH, MUCH BETTER IN PERSO!
