Oregon Sunstone is unique in the world for the presence of copper Schiller as a phenomenon. Oregon Sunstone is a Labradorite Feldspar. Its colors come from the presence of copper mingling with molten gem material. The color palette ranges from pale yellow , to peach, all hues of orange, to red-orange, as well as light to dark teal green and Rootbeer brown. These photos show another way that the presence of copper manifests itself - as "glitter" called Schiller. This can occur as spots, streaks or a general plane of shimmer seen all across the surface of a faceted gem. (Local American Indian tribes use Sunstone in their Medicine Wheel ceremonies due to its dual anti-inflammatory properties.)
