An absolute classic, Dioptase on white Calcite is one of the most desired combinations from Tsumeb, and that's saying a lot! These medium-green Dioptase crystals have excellent luster and are uniformly quite gemmy. They range up to 7 mm in size, and the contrast in color against the white Calcite creates the splendid aesthetic that this pairing is known for. The separation between the Dioptase crystals allows you to appreciate the beauty of the individual crystals. This is a fine miniature and highly representative for Tsumeb from the mid 198s0.
