Sunstone is translucent to transparent feldspar. It produces metallic flashes. When the light comes in interaction with tiny plates like inclusions of minerals that exist within the stone. When light reflects them at a common angle after entering the stone, the observer feels a unique play of colors. Sometimes it appears like a cat's eye.
