Sunstone is an oligoclase feldspar that can only be found crystallized in large masses. The name comes from its obvious resemblance to the sun, especially when exhibiting radiant reflections that show “flash” or chatoyancy (commonly caused by inclusions of Goethite or Hematite). A lot of Sunstone throughout the world has slight differences in color and can range from peach-pink to bright orange, as well as a light red.
