Oregon Sunstone is a feldspar crystal formed in molten lava and then discharged onto the surface of the earth by a volcano. While feldspars are found world over they are rarely gem grade. In addition, Oregon is one of the few places that this material is found with copper in it. Varying amounts of this mineral causes the stones to range in color from clear to many shades of green, red and pink. Some stones will contain from two to four of these colors. No two stones are exatly the same, each is as unique as the individual owning one of these gems.
Oregon Sunstone, found only in the remote high desert of south east Oregon, was named the Oregon State Gemstone in 1987.
I personally facet all my stones. Set in fine metals the two compliment each other to become a valuable peice of jewerly. Enjoy your unique peice of Oregon.
