Oregon Sunstone is a rare gemstone that was honored as Oregon's state gem in 1987. Before the discovery at the Ponderosa mine, the term "sunstone" referred to feldspar minerals with a glittery effect or golden sheen, a phenomenon known as aventurescence.

Depending on the abundance and size of the copper trace elements and platelets within the gem material, the color may vary from colorless to yellow, orange, brown, pink, red, green, blue-green and multi-colored. Copper can create a range of shades from green, yellow, orange to red.
