Dioptase Specimen – Emerald Crystals on Matrix, Tsumeb Namibia Collector Mineral, D3

Dioptase specimen from the Tsumeb Mine, Namibia displaying prominent emerald-green crystals with notable shape and size rising from the natural matrix. This cabinet specimen highlights the sculptural crystal habit that has made Tsumeb dioptase one of the most celebrated copper minerals in the mineral collecting world.
Unlike densely micro-crystalline clusters, this piece showcases distinct, individually visible crystals with well-defined faces and strong geometric form. The crystals rise cleanly from the matrix, allowing their structure to be appreciated from multiple viewing angles. Their saturated emerald coloration and glassy luster create a striking contrast against the host rock.
The Tsumeb Mine in Otjikoto, Namibia is considered one of the greatest mineral localities ever discovered, producing museum-quality specimens across hundreds of species. Dioptase from this locality is especially prized for its exceptional color intensity and well-formed crystal habit. Specimens mined during the 1998–2006 late mining period are increasingly scarce since the mine’s closure.
