Oregon Sunstone is a plagioclase feldspar formed in lava flows that cover much of southcentral Oregon, specifically found in Harney County, Oregon and in eastern Lake County north of Plush. Only Oregon sunstone contains inclusions of copper platelets that give it its beautiful range of colors from clear to luminescent copper known as schiller, to deep red, teale green-blue and even bi-color and dichroic. The copper leads to variant color within some stones, turning a stone can result in manifold hues. The more copper within the stone, the deeper the color saturation.

Originally collected and used by Native Americans, the Plush Sunstone is said to lend protective energy and provide healing properties. Oregon Sunstones are often found in sacred bundles and in local Native American burial sites. Sunstones were traded as far east as the Mississippi river, and as far north as Alaska.
Since then, gem quality Oregon Sunstone has enchanted countless jewelry artisans and consumers in the US and around the world.
