This choice thumbnail specimen from Tsumeb mine is a stunning example of Zincolivenite crystals. Not only are these crystals the most desirable glossy leaf green colour, but they are large (at up to 9 mm across) and well-formed and rise up strikingly from a contrasting bright yellow matrix of Ferrilotharmeyerite. Ex Benjamin Schumer collection, no. 2004.

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.
