An excellent creamy spearmint-green specimen of Zincolivenite with single crystals up to 0.8 cm. Most of the crystals show small etch patterns on their prismatic faces, while the terminations are quite sharp. From Tsumeb mine in Namibia, this is a relatively new species, whereby it embraces all intermediate members of the adamite-olivenite solid solution series. By definition, this species will have a composition of zinc to copper of between 75:25 to 25:75. Outwith these bounds lie Adamite (the zinc arsenate end member) and Olivenite (the copper arsenate end member). This is a rich and showy specimen of Zincolivenite and an excellent example from Tsumeb.

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.
