Description

Pink germanite from the collection of Karl Seifert (karlseifertite). Karlseifertite as well as zincostottite were found in this germanite material. 

This is the largest germanite piece that I had in my own hands.

Mr Seifert's professional career spanned nearly 50 years, much of which was spent as an engineer and prospector for mining companies in Namibia (South West Africa for most of that period). From 1963 to 1967, he was mining engineer for Tsumeb Corporation Ltd. (TCL), which operated the Tsumeb mine (Tsumcorp mine). Karl Seifert was well known for his expertise in geology and mineralogy, particularly with respect to mineral exploration. He also had a passion for mineral collecting and assembled an extensive collection through his many diverse mining pursuits.
