Chrysocolla is a copper silicate mineral with the chemical formula Cu₂H₂Si₂O₅(OH)₄·2H₂O. It is typically found in blue, green, and turquoise hues, often with veins or blotches of darker colors. Chrysocolla is relatively soft, with a Mohs hardness of 2.5 to 7, depending on its form and composition, making it more suitable for beads, cabochons, and ornamental carvings. It is commonly found in regions with copper deposits, such as Chile, Mexico, the United States (Arizona), and Zaire. Chrysocolla is valued for its vibrant color and is often used in jewelry.
