Hydrozincite, Smithsonite
Miniature, 4.3 x 3.9 x 2.8 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
Hydrozincite is an alteration product of smithsonite, sphalerite or hemimorphite. This fine specimen from the Tsumeb Mine features an aesthetic cluster of sharp, brown smithsonite crystals with a powdery dusting of gray hydozincite microcrystals on a nicely contrasting crust of calcite. The largest smithsonite rhomb, 1.8 cm, is perched at the top of the specimen. Ex. Rob Smith Collection.
