Chrysocolla 3mm Round Bead 15-16 Inch Australian "Boulder" Chrysoprase but those varieties are transparentChrysocolla, a hydrous copper silicate, is often mistaken for turquoise due to its rich blues and blue to greens. 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.
