Isolated, gemmy and lustrous, dark emerald-green dioptase crystals to 1.1 cm are aesthetically scattered on the 3-dimensional matrix of gray calcite on this showy and excellent old-timer from the famous Reneville Mine, Republic Of The Congo. The malachite on the calcite is a nice accent. Comes with an old Wards label from Djoue, another name for Reneville. Dioptase of this quality came out in the 1950s and 60s. Ex Charles Hansen Collection, a noted California collector.
