Oregon sunstone is a rare, gem-quality variety of copper-bearing plagioclase feldspar found uniquely in the volcanic high deserts of Southeastern Oregon. Unlike most global sunstones that owe their sparkle to hematite, Oregon sunstone gets its vibrant colors and signature inner glitter—known as inschillerin or aventurescence—from millions of microscopic, natural copper inclusions.
Geographic Isolation: It is exceptionally rare because true copper-bearing sunstones are found nowhere else on Earth outside of a few private mines and public collection areas in Lake and Harney counties.Color Rarity: While clear, pale yellow, and champagne stones are relatively common, intense reds, bi-colors, tri-colors, and deep green-blue shades are highly elusive. Green and blue-teal are considered the ultimate rarities in the sunstone world.Size Constraints: Most gem-grade specimens range from 1 to 2 carats. Rough stones that can yield clean, faceted gems exceeding 5 to 15 carats are immensely scarce.HistoryIndigenous Origins: According to Native American lore, the stone formed when the blood of a great warrior dripped onto the gems, infusing them with sacred power and shades of red. Artifacts embedded with sunstones have been found at regional historic sites.Early Mining: Rediscovered by modern travelers in the early 1900s within ancient lava fields near Warner Valley, the remote deposits slowly grew in popularity among rockhounds and collectors.State Designation: In 1987, the Oregon Legislature officially named the sunstone the state gemstone. This was heavily inspired by the famous 1985 discovery of the inPonderosa Queenin—a stunning 40-carat piece of rough that yielded spectacular deep-red faceted gems.
