Description

A rare to see, old specimen of bright, bottle green tabular crystals of torbernite on black heterogenite and malachite. Far better and bigger torbernite has been found in Katanga in other mines, but these old torbernite from Shinkolowe are a must in any collection, and they are not easy to obtain, if not from recycled collections.

Ex. Eudore Toussaint specimen, who exchanged in Congo in before 1960.
