A rare blue-green mineral, a hydrated copper arsenate, with a monoclinic crystal structure.
From Greek klino- (inclined, monoclinic) plus -clase (from Greek klastos, meaning 'broken' or 'cleavage'), referring to its crystal system and fracture properties.
Clinoclase is so rare that many collectors will never see it, but its beautiful blue-green color and monoclinic system make it a treasured find among mineral enthusiasts!
