Dioptase on Calcite
Miniature, 4.8 x 3.2 x 2.4 cm
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Ex. Al Ordway

The best dioptase specimens from Tsumeb (circa early 1980s) are generally considered to be those perched upon color-contrasting, white calcite, as here. Glassy and gemmy, rich emerald green dioptase crystals, to 9 mm across are emplaced on a crystallized druse of white calcite. Although one of minor side-car crystals is slightly contacted, the overall piece is outstanding and beautiful, a choice miniature for this important find without breaking the bank as they usually do.
