A very glassy and lustrous, dark emerald-green, 1.5 cm dioptase crystal nicely set on a matrix of smaller dioptase crystals from Tsumeb. A super-trivial edge wilbur on the upper right side is barely noticeable and the periphery damage to some of the smaller crystals is certainly not detracting. From the noted thumbnail collection of marilyn dodge 2.0 x 2.0 x 1.6 cm
