2.0ct Cuprian Opal, Andes Mountains
2 ct Copper Bearing Opal, Mined in the Andes Mountains
10.4 x 7.4 x 5 mm Cabochon, U.S. Cut
Vivid color and velvety Cuprian glow make this gem material truly special. This freeform diamond has a nice pillowy shape, with depth to really bring out rich color. There is an area of potch remaining on the surface of one corner, but it should easily be covered in setting (especially bezel setting, which I recommended for this material).
