Copper with Mimetite on Smithsonite
This specimen is quite unusual. Native copper in any form is rare at Tsumeb, let alone in a dendritic / arborescent form. With the association of a smithsonite covered matrix and Mimetite, this specimen is quite uncommon. Under magnification there are also a few small sharp cuprites and what looks like a second generation of Mimetite.
A very special combination piece!
Measures 75 x 40x 35mm
Ex A. Kissling collection.
