Conichalcite on Dolomite
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Miniature, 4.8 x 4.1 x 1.3 cm
Ex. Martin Zinn
A very rare example of conichalcite in discrete crystals (botryoids, rather), from this mine: the piece features 1 mm spheres of dark green conichalcite, an uncommon, calcium, copper arsenate. They are festooned over a matrix of white dolomite. Rare! Ex. Marty Zinn collection
