Emerald green dioptase on calcite, from tsumeb is highly desired. Colorless, glassy and gemmy rhombs of calcite on emerald green dioptase is much less common, but still highly desired. Equant calcite rhombs, to 9 mm across festoon glassy and gemmy, emerald green dioptase, in crystals to 4 mm across. A wonderfully contrasting and very desirable specimen!
