Mooney Fine Mineral

Via Mindat

Name: 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.
A mineral of secondary origin, commonly associated with other secondary copper minerals, it is typically found as glassy botryoidal or rounded masses or bubbly crusts, and as vein fillings. Any acicular or fibrous chrysocolla "crystals" are all pseudomorphs.
