Description

MANGANOAN SMITHSONITE: SINGULAR FIND
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
This rare specimen dates from 1985 when the only pocket of its type was found in the mine. Individual sharp, rhombic crystals to 5/8 inch across were found scattered over an atypical grey matrix with druzy Pyrite. Unlike most of the pink Smithsonite found there, the color in this specimen is caused by the presence of Manganese, not the more normal (for Tsumeb); Cobalt. There is a 'notch' in one of the main crystals which shows signs of being part of a complex growth habit. The condition is excellent and this rare specimen measures 2 ¾ x 1 ¾ x 1 7/8 inches.
Provenance: Ex Stoudt Collection of Midland/Houston, Texas
