ABOUT THE GEMSTONES
Chalcedony is an amazingly rich and diverse family of gemstones. Naturally colored black chalcedony is quite rare, and difficult to source today.
Sunstone is part of the feldspar family. While sunstone is found in localities throughout the world, Oregon Sunstone is the exclusive locale for sunstone colored by the presence of copper. This creates a range of beautiful and unique colors available in this gemstone. Oregon Sunstone also exhibits an effect known as copper schiller (or aventurescence); this phenomenon is most easily described as a metallic glitter which appears suspended within the gemstone.
