Dioptase, Calcite
Small Cabinet, 6.4 x 5.3 x 0.3.5 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
What makes this Tsumeb dioptase specimen so gorgeous is that the small, intensely sparkling crystals are isolated on the contrasting white calcite rather than being massed together - which really makes them jump out at you. Of course, ALL Tsumeb dioptases are now highly sought-after - they and azurites are probably THE stars of this famous locality which probably ranks as the most productive of great specimens in history.
