An excellent and very rich vivid emerald-green Zincolivenite, formerly named Cuproadamite. Adamite and Olivenite form a continuous solid solution series, with Adamite forming the zinc-rich end member; the copper-rich end being Olivenite. Zincolivenite lies within the 75:25 and 25:75 percentile boundaries. A mid-grey sulphide-rich matrix is heavily veined with massive Zincolivenite and lustrous crystallised Zincolivenite lining two broad, shallow vugs, measuring 3.5 x 1.5 cm and 2.5 x 1.0 cm respectively. Several small white patches within the Zincolivenite are likely to be the equally rare species Schultenite. Zincolivenite occurs in each of the three oxidation zones at Tsumeb mine.

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.
