Description

Old classic from Macha (Bolivia) is this botryoidal wood tin cassiterite. It is a lustrous and quite aesthetic elongated multi-layered specimen. Such cassiterite pieces are very uncommon nowadays because they were originated from a few historic localities and in limited volumes. This was collected in the late 1940’s by Dr. Fritz Berndt (Berndtite is named after him). Ex Dr. Jaroslav Hyrsl; Ex Chris Deroo.
