Chrysocolla Boulder
Democratic Republic of the Congo
Chrysocolla is a hydrated copper silicate, a mineral that forms in the oxidation areas of copper ore where it is associated with a number of secondary copper inclusive minerals. Due to its attractive blue-green color it is sometimes confused with turquoise. The hardness is sufficiently high to allow for a bright, mirror polish. Contour polished to reveal concentric circles of brilliant blue and green creating a striking visual impact. Measures 10 x 9 x 2in
