Willemite Pseudo. After Azurite
Miniature, 4.3 x 3.1 x 1.5 cm
29th Level, Tsumeb, South West Africa
Ex. Dr. Mark Feinglos
An exceptionally rare pseudomorph from the mine, from one single pocket found in the 1970s I am told. This is an excellent single crystal! It features blue willemite on the inside, with a layer of white willemite outside, on which small mimetites also rest.
