Here we have a very good, classic Tsumeb combo of Dioptase on Calcite. Both species are well-crystallized and the Dioptase crystals reaching 7 mm in size. The crystals are super sharp edged and excellent terminated with an intense emerald green colour. For it´s richness and size ( miniature) this is a choice specimen of this desirable combination! It is sparkly and leaps off a shelf in a way hard to capture. Dioptase is notoriously difficult to photograph well but this is a top specimen with great overall aesthetics. Minor imperfection at the periphery.
