Arizona
A rare stone from the copper mines of Arizona, the premier source for the material. Chrysocolla has an attractive blue-green that provides a unique color to the gem world as it forms in the oxidation zones of copper rich ores. When chrysocolla “agatizes” in chalcedony quartz it is then called “gem silica chrysocolla”, with the quartz component providing the stone its polish and durability. This large, oval cabochon has a pleasant, sea bluish-green color and good translucency. Weighing 21.5 carats and measuring 31.0 x 19.5 x 4.5mm.
