Sunstone

Sunstone, a captivating variety of feldspar, is renowned for its dazzling "sunstone effect"—a golden, glittering phenomenon caused by microscopic inclusions of hematite, goethite, or copper platelets that reflect light like scattered sunbeams. This radiant optical display, also called aventurescence or "schiller effect," gives the stone its name and fiery personality, evoking the warmth and brilliance of sunlight.
