- Dioptase, Malachite, Calcite
- Cabinet, 12.0 x 11.0 x 6.7 cm
- Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
Sparkling, gemmy, emerald-green dioptase microcrystals cover the undulating, cabinet-sized matrix coated with contrasting, highly desirable, white calcite. All on this excellent larger specimen from the Tsumeb Mine. This striking piece is unusually highlighted with a scattering of primary malachite balls to 1.0 cm. The balls consist of tiny needles of malachite and you can see dioptase crystals on the balls. Dioptase and malachite are an uncommon association, in fact. Fascinating, choice combination material from this noted locale. Ex. Matthew Webb Collection.
