COBALTOCALCITE CAST AFTER DOLOMITE
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
One of the more exotic looking minerals found at Tsumeb is a bubble-gum pink version of Calcite referred to as Cobaltocalcite or Cobaltoan Calcite. In the case of this specimen the material seems to have been deposited over another mineral; probably Dolomite, giving the piece a strange, swirling surface texture. To add to the visual intrigue, the exterior surfaces are tinted a light smoky tan color providing a level of contrast unusual even for Tsumeb. There is a small amount of adhering matrix on one end and some Malachite on the back side. In excellent condition it measures 4 x 3 x 1 ¾ inches.
Provenance: Ex Stoudt Collection of Midland/Houston, Texas
