An extremely popular gem that originated in south-central Oregon, the Oregon Sunstone is the state’s official gemstone known as the “Oregon Sunstone.” Some of these may be found in particular basalt flows in Lakeside and Harney counties, respectively.

The sunstone resources in Oregon are just significant enough to support industrial mining operations in a limited number of locations.

Most of Oregon’s sunstones are created from the soil horizon above the basalt flow, with a small number of sunstones formed from the basalt flow. There are several active mining claims in the Oregon basalt flow containing the stone. The majority of the lucrative regions are situated on federal properties overseen by the Bureau of Land Management.

For centuries, people have known about the gemstone, which was found by Native Americans who cherished it. These Native Americans, who traded in crystals on a large scale, might even bury the stones beside their corpses.
