Sunstone For Sale
Known for its warm, radiant glow and captivating shiller effect, Sunstone is a gemstone of leadership and light. Whether sourced from the plains of Tanzania or the mines of Oregon, these gems carry a distinct metallic glitter caused by tiny inclusions of copper or hematite.
The Science & Beauty of Sunstone
Sunstone is a member of the Feldspar group. Its most famous characteristic is aventurescence—the brilliant flash of light that dances across the surface of the stone. In Tanzanian Sunstone, this is often caused by plate-like inclusions of hematite, giving the stone a multidimensional appearance.

Frequently Asked Questions
What creates the "sparkle" in Sunstone?
The sparkle, or aventurescence, is caused by light reflecting off tiny, flat mineral inclusions (like copper or hematite) trapped within the crystal structure.
Is Oregon Sunstone different from other Sunstones?
Yes. Oregon Sunstone is unique because its sparkle is caused by copper "schiller," whereas other varieties (like those from Tanzania) usually contain hematite or goethite.
Is Sunstone suitable for everyday jewelry?
While beautiful, Sunstone is slightly softer than Quartz. We recommend it for earrings, pendants, or protected ring settings to prevent scratches.
