Oregon Sunstone Cabochons with Schiller inclusions.
These four Oregon Sunstone Cabochons are beautifully polished and ready to become part of your collection. Each one shows rich peach to red color with attractive eye visible Schiller phenomenon.
What is Schiller? Oregon Sunstone is a unique feldspar mineral. Other types of feldspar can be found in several other parts of the world. However, only Oregon Sunstone exhibits the tiny copper platelets formed inside the stone. Because of this, the copper creates a luminous metallic effect within the stone called “Schiller.” These copper mineral inclusions cause a glittering reflection in the gem seen from the surface.

At The Sunstone Store our all time favorite gem is the Oregon Sunstone, in part because of its amazing array of naturally occurring colors from reds to greens, champagnes, and the unique copper included “schillers.”
