Large intergrown lustrous crystals, to about 7 mm across, of Zincolivenite, cover the surface of a very large miniature to small cabinet-size brick-red, iron-stained Dolomite matrix from Tsumeb mine. The Zincolivenite is most unusual in that its colour varies markedly, including bluish amazonite-green; dark-leaf green and opaque pale peppermint greenish-white. Individual crystals can exhibit all three of these colour variations, giving a patchy, mottled appearance. The crystals are sharp and well terminated and form a fascinating and somewhat different Zincolivenite 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.
