Stibioclaudetite (Type Locality)
Thumbnail, 1.7 x 0.4 x 0.2 cm
Zinc Pocket, 44th Level, Tsumeb Mine, Tsumeb, Namibia
SOLD

Stibioclaudetite is a very rare zinc arsenate found at Tsumeb. 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. This specimen is from the Zinc Pocket on the 44th level, one of the deepest parts of the mine. Leiteite and Ludlockite are among the most well known of these Type Locality rarities. This exceptional, single crystal is gemmy, lustrous, and sharp, which contrasts with the more common fibrous and white specimens. It came from a later pocket after the first find, and was unique in the sharp, gemmy crystals from this small pocket - and remains so, to this day. It is an IMPORTANT specimen and crystal for a very interesting species that also happens to be a competitive level thumbnail specimen. This is a superb and important example of the species. Ex. Mark Rattay and Marshall Sussman (from his important rarities suite, sold off in 2003 to me). Much better in person. In 25 years of being a dealer at a level enough to notice, I have seen only three crystals for sale from this pocket.
