Sunstone

About

Sunstone Crystals Sunstone is a plagioclase feldspar — typically oligoclase or labradorite — distinguished by aventurescence: a glittery optical effect caused by reflective inclusions of copper or hematite platelets suspended within the crystal. When light hits these inclusions, the stone flashes with warm metallic sparkle. Sunstone registers 6–6.5 on the Mohs scale. Indian sunstone is the most widely available variety, with a warm orange base and subtle copper shimmer. Oregon sunstone is rarer and highly collectible — its copper inclusions produce vivid red, green, and bicolor flashes unique among feldspars. Oregon sunstone is the official state gemstone of Oregon. Sunstone also comes from Norway (the original discovery locality), Tanzania, Canada, and Russia. Available forms include tumbled stones, palm stones, spheres, pyramids, and towers.
