Green Oregon Sunstone Cabochon, 3.22ct Round 9x9mm, Untreated | OSC270
Green Oregon Sunstone Cabochon, 3.22ct Round 9x9mm, Untreated | OSC270
This Oregon sunstone cabochon is a round cabochon cut for jewelry making, with a deep color showing both green and red across the dome. The seller describes the color as a rare combination of green and red in a deep tone, with the schiller effect catching light as the stone is turned.
As a graduate gemologist, I'm always drawn first to color, and this is a stone where the color truly carries the piece. It would make a striking centerpiece for a ring or pendant where the stone is left to be the star.

Sunstone is a feldspar, durable enough for most jewelry, with a cleavage that means a sharp knock can split it. Its glitter and color come from tiny reflective inclusions inside the stone. Rings benefit from a protective setting. Clean with warm soapy water, and avoid steam cleaners.
