Mimetite, Beaverite
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
Thumbnail, 2.0 x 1.4 x 1.3 cm
This fine Gem Pocket thumbnail specimen is highlighted by two mimetite crystals: a 1.0 cm, gemmy crystal jauntily projecting upward; and a fat 9 mm horizontal mimetite with a contacted termination. Both crystals lie among smaller mimetites in a field of earthy, yellow-green beaverite on a bit of matrix. Beaverite is a rare sulfate and is very rare from Tsumeb. Ex. Irv Brown Collection.
