Arusha Sunstone 阿魯沙

Sunstone is a plagioclase, member of the Feldspar family, and is named for its warm shades of gold, orange, reds and browns that sparkle like the sun. Inclusions of Copper, Hematite, Goethite, Ilmenite, Pyrite, or other metallic, refract light between the different crystal layers and produce an iridescent effect as the stone is viewed from various angles. Sunstone may be clear and transparent, or opaque, and is readily available on the market. Clean red specimens, however, are rare.
