This is a choice Zincolivenite thumbnail from the famous Tsumeb mine in Namibia. It comes from John Schneider's famous Tsumeb collection and bears the earlier name of this species - as Cuproadamite - on his acrylic base. The specimen is composed entirely of Zincolivenite as an aggregate of large, well formed, slightly curved, deep leaf-green crystals. Individual crystals reach up to 9 x 6 mm by over 5 mm tall and form a circular domed group. The sides of the crystals have a thin outer rind of light limey peppermint-green Zincolivenite which frame and highlight the individual crystals beautifully. A superb Tsumeb mine thumbnail specimen with great pedigree.

Zincolivenite from Tsumeb Mine, Namibia
from Tsumeb is the modern name for much of the vivid green “cuproadamite” and “cuprian adamite” that circulated for decades from this legendary Namibian mine. It sits between adamite and olivenite in the adamite–olivenite solid-solution series, with ideal composition CuZn(AsO4)(OH), and Tsumeb is one of the places where that chemistry becomes a collector’s problem as much as a mineralogical one: color, habit, and zoning can suggest the identity, but the most careful determinations rely on quantitative chemical analysis.
