Descloizite

This is a de-acquisition piece from the New Mexico Tech Mineral Museum (with label). I recognized this habit quickly as it was most unusual when I first saw this style in Namibia where I was informed this is typical of a copper rich variant. Very distinctive axehead crystals mounded together with a matte luster.

Locality: Berg Aukus Mine, Grootfontein, Namibia

Composition: Hydrous vanadate of lead and zinc
