Azurite, Arsentsumebite
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
Miniature, 3.6 x 3.9 x 3.1 cm
Rich, apple green, arsentsumebite, a rare lead copper-arsenate-sulfate, contrasts incredibly with a few crystals of highly lustrous, deep, royal blue azurite, to 1.0 cm across. This is a notable old specimen, rare today, showing a classic association from Tsumeb and only Tsumeb. Mostly these were found in the early days of Tsumeb, early 1900s. Ex. Charlie Key.
