Chrysocolla is characterized by splashes of blues, blue-greens and greens, and marble-like markings.In some stones the colorations are especially vivid, contrasting sharply with this stone's vitreous and earthy (nonreflective) luster. Chrysocolla is a hydrous copper silicate that is often mistaken for Turquoise due to its rich blues and blue-greens. It often occurs with colorations 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 named the stone in 315 BCE. Chrysocolla that intergrows with Turquoise and Malachite is referred to as "Eilat Stone," since it is found in Israel near the town of Eilat. Variations of this beautiful gift from Mother Nature are found in Chile, Peru, the former USSR, Zaire, and the USA (Arizona).
