Zincolivenite is a relatively newly named species from Tsumeb as it represents the intermediate chemistry of the adamite-olivenite solid solution series. Two primary clusters of dark-apple to bottle-green Zincolivenite rest on an attractive bed of an unknown, yet beautifully crystallised mineral, most probably Bayldonite. Once identification is confirmed, this will itself become an important part of this specimen, not just a background species. Bayldonite or not, it forms as bubbly micro-druses of rich pistachio-green crystals of less than 1 mm diameter all with sparkling lustre. The Zincolivenite forms crystals to about 8 mm long, clustered in stacked booklets and as occasional individual crystals. An impressive miniature of this interesting species.

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.
