4.2ct Cuprian Opal
4.2ct Copper Bearing Opal from the Andes Mountains
Cut in Canada by Hans Durstling, 9x14x6mm
A glowing Blue/Green Opal Teardrop, with color that shifts from more Green outdoors and Bluer indoors! Copper Bearing Peruvian Opal is quite difficult to source, so I felt lucky to obtain a small parcel of rough, then sent them for cutting by our best cabochon artist.
