This is a mimetite of the highest quality from Tsumeb. It features sharp, incredibly lustrous hexagonal dipyramids of yellow translucent-to-transparent mimetite. In excellent condition, with minor calcite in association. From the Tracy Kimmel collection, this specimen was collected in 1982. It was formerly in the Desmond Sacco collection and Tracy then acquired it from Jordi Fabre. A top-quality, classic Tsumeb mimetite!
