Leiteite (Type Locality) w/ Tennantite (Matioli Coll.)

Item Description

Leiteite is an ultra rare zinc arsenate and Holy Grail rare species for the famous and now-closed mine, which is the Type Locality. It was named in 1977 from a single aberrant specimen found at Tsumeb, and then found sparsely in a few more pockets in the so-called germanium levels of the final and deepest part of the mine. In all the previous years at Tsumeb, none had been found until the miners went down to a third oxidation zone and encountered a bizarrely germanium-rich zone from which new species came in profusion. A sharp, 2 mm, tennantite crystal is smartly embedded in pearlescent leiteite lathes on this nifty combination thumbnail from Tsumeb. Excellent and uncommon combination material from the Matioli Collection.
