4.1 x 3.7 x 2.1 cm. Specimens of tetrahedrite from Altenberg are rarely available, and they are only seen in old collections, as they were mined in 1800s. This is a rich specimen loaded with incredibly sharp, very lustrous/splendent, metallic, tetrahedral crystals of silvery-grey tetrahedrite measuring up to 6 mm sitting on siderite and quartz on matrix. The crystals are beautiful to view up close and really stand out as fine examples of the species from Altenberg. Ex Kay Robertson Collection (#6676) and Carl Bosch Collection (#B3768) via the Smithsonian. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien-Welt" November-December 2017).
