Outstanding specimen of lustrous, deep green Dioptase crystals on matrix showing UNUSUALLY good isolation to the crystals for the material. The largest Dioptase is an impressive 1.5 cm, and they are gemmy and rich. Associated are mm-size Calcites rhombs (fluorescent) and Duftite. There is also a dusting of a mineral that fluoresces blue-white, possibly Cerussite. Excellent Dioptase in and of itself, and an equally choice combination piece.
