This gorgeous cabochon of Chrysocolla is from the Rowley Mine here in Arizona. Chrysocolla is a copper bearing mineral found wherever copper deposits occur especially in areas of the southwestern USA, Chili, Zaire, Australia, France and England. Pure chrysocolla is too soft for jewelry purposes but it is often found in quartz deposits which makes it hard enough to polish for cabochons. It is often found mixed with malachite, turquoise and azurite.   This gemstone is rarely minded today, which is what creates its high price tag.
