It often also occurs with colors of rust, copper, black, white and reddish brown in speckles, veins and brecciated patterns. It is a very soft stone typically found near copper deposits. Chrysocolla was first described by Theosphrastus, a Greek philosopher and botanist who also named the stone, in 315 BCE.
