Classic, vibrant green, sharp Zincolivenite crystals liberally line several cavities within iron-rich dolomitic host rock from Tsumeb mine, Namibia. The Zincolivenite crystals are small, exceptionally reaching 2.5 mm in length, but generally around the 1 mm mark, and are actually not uniformly green - showing zonation from deeper green tips and paler centres. The cavities, of which there are many, extend to 2 x 1 cm (with another 2 x 1 cm extension off from it), 1 x 1 cm, 1 x 0.9 cm and 0.9 x 0.9 cm. Although the crystals are small, there is extensive coverage and they are very glossy. Overall, a very fine Zincolivenite.

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.
