Sunstone aka Aventurine Feldspar

Sunstone also known as aventurine feldspar is a variety of the mineral feldspar which exhibits a spangly appearance correctly known as aventurescence.  This optical phenomenon is caused by the presence of tiny plate-like inclusions of the minerals goethite or hematite but copper can also very occasionally be present.  The more heavily included the stone the more desirable it is.  The inclusions are the cause of the aventurescence.

Heliolite which comes from the Greek word 'helios' meaning 'sun' and 'lithos' meaning 'stone' was once used as an alternative name for sunstone but is now very rarely used. 

Sunstone is one of the few gemstones that's never enhanced.  On Mohs scale of mineral hardness it grades 6 to 6.5 which means it's relatively hard.  Hardness however should not be confused for toughness which relates to a rock or mineral's resistance to cracking, breaking or chipping.  The characteristic known as hardness relates to how easy a stone can be scratched by another rock or mineral.  

Sunstone comes primarily from India, Canada, Norway, China, United States (in particular Oregon) and Russia.

Sunstone Versus Goldstone

Goldstone is a man-made material also known as aventurine glass and is often used to imitate the mineral sunstone.  In goldstone tiny specs of copper reflect light from within the stone which give a similar appearance to the aventurescence seen in sunstone.
