Tsumeb Dioptase Specimen – Emerald Green Crystals on Matrix, Namibia Collector Mineral, D8

Dioptase specimen from the Tsumeb Mine, Namibia featuring vivid emerald-green crystals naturally formed on the surface of the host rock matrix. This compact cabinet specimen highlights the striking color contrast between the copper-rich crystals and the earthy mineral base.

Several small but well-defined crystals are beautifully formed over the matrix, allowing the natural structure of the host rock to remain visible while still showcasing the brilliance of the dioptase. Each crystal exhibits the mineral’s signature glassy luster and saturated emerald coloration, created by copper within the crystal lattice.

The crystals display the classic prismatic to rhombohedral habit typical of dioptase, reflecting light with bright flashes of green as the specimen is viewed from different angles. Even with a modest crystal coverage, the vivid color gives the piece a strong visual presence.

The Tsumeb Mine in Otjikoto, Namibia is one of the most famous mineral localities in the world. Renowned for producing exceptional copper minerals and rare species, the mine yielded some of the finest dioptase specimens ever discovered. Specimens mined during the 1998–2006 period represent part of the final era of production from this historic deposit and are increasingly valued among collectors.
