- Tantara Mine, Katanga Province, Democratic Republic of the Congo
- Overall Size: 6.5 x 3.3 cm
Extraordinary for Tantara and one of the best of its kind. This is the only place where such exotic combinations occur together in splendid examples. The rarity lies in unexpected crystals of dioptase on replaced calcite. More precisely, this pseudomorph is layered with malachite over a layer of dioptase, and the entire replacement itself is after calcite. It is a superbly composed specimen with excellent aesthetics, for these modern classics in the making. Ex Rosa Nowels collection
