This 12.00 carat cabochon of Oregon Sunstone from the legendary Spectrum Mine in Plush, Oregon is a radiant embodiment of natural alchemy. Measuring 24.4mm x 8.65mm x 7mm, the elongated freeform is saturated with high-density copper schiller—an optical phenomenon caused by thousands of microscopic copper platelets suspended within the feldspar matrix.

As light glides across the surface, these aligned platelets generate a warm, metallic chatoyancy—rippling flashes of rose-gold, flame orange, and sparkling copper that move in response to orientation and illumination. This isn’t just shimmer—it’s internal architecture creating visible lightplay, and it’s what sets Oregon Sunstone apart from all other feldspars.

The Spectrum Mine is celebrated for producing some of the richest copper-bearing labradorite in the world. This particular piece exemplifies that legacy, with both clarity and density of inclusions dialed to perfection. Whether admired as a display specimen or destined for a bold, fiery setting, it captures the magic of schiller at its most vivid and tactile.
