Oregon Sunstones are a rare and beautiful type of feldspar that contain copper inclusions, creating a shimmering effect known as "schiller." Found exclusively in the high desert of Oregon, these gemstones offer a unique and rewarding experience for gem hunters. This guide explores key mining locations, practical tips for visitors, and unique insights into the geological wonders of Oregon Sunstones.

How Did Oregon Sunstones Form?
Oregon Sunstones were formed during volcanic eruptions over 13 million years ago. The copper inclusions in these stones create a variety of colors, from clear and pale yellow to rich reds and greens. These inclusions also produce the "schiller" effect, adding value to the stones (Oregon Discovery) (opb).
Where did Sunstones Originate?
Recent research has revealed new insights into the origins of Oregon Sunstones. Initially believed to be linked solely to the Steens Mountain basalt flows, studies now suggest that deposits such as those at the Ponderosa Mine originate from the Picture Gorge Basalt (opb). This finding expands our understanding of the region's volcanic history and highlights the importance of continued geological research.
