A rare example of Gypsum from Tsumeb occurring here on a mixed Malachite and Azurite matrix with part crystals of Malachite pseudomorphs after Azurite. The Gypsum forms a stack of cleaved transparent rhombohedrons measuring 2.4 x 1.4 x 0.7 cm. When associated with ore mineralisation as with this specimen, Gypsum only occurred at Tsumeb in either the supergene (near surface) zone or first oxidation zone. An old-time specimen of this rare Tsumeb species.
