The name was first used by Theophrastus in 315 B.C. and comes from the Greek chrysos, meaning “gold,” and kolla, meaning “glue,” in allusion to the name of the material used to solder gold. André-Jean-François-Marie Brochant de Villiers revived the name in 1808. Chrysocolla forms in the oxidation zones of copper rich ore bodies.
