This effect is attributed to small inclusions of hematite or goethite minerals or sometimes copper, which reflect light. The color of the sunstone usually ranges between orange, red, golden, or yellow-green, and it can be transparent to translucent. This stone forms in igneous and metamorphic rocks.
