Sunstone Properties and Meaning

Sunstone or aventurine feldspar is a variety of the mineral feldspar which exhibits a spangly appearance that's 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 more desirable the stone and the sole cause for the aventurescence seen in sunstone are the inclusions.  Heliolite which comes from the Greek 'helios' meaning 'sun' and 'lithos' meaning 'stone' was once used as an alternative name but it's now very rarely used.  The scientific name for sunstone is aventurine feldspar. 

Sunstone is one of the few gemstones that's never enhanced.  On Mohs scale of mineral hardness it grades 6 to 6.5 which makes it relatively easy to work with.  Stones come primarily from India, Canada, Norway, China, United States (in particular Oregon) and Russia.



What is Goldstone?

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



Sunstone for Crystal Healing

When used as a healing crystal it's said to be a stone of protection which increases the power of ones personal attraction.  It can be used to clear and energize the chakras and to dissipate fear and alleviate stress.  In Ancient Greece sunstone was thought to represent the sun God hence bringing life and abundance to those fortunate enough to carry or wear it.  It was also used for ornamental purposes in goblets and plates as it was believed to counteract the effects of poison and produce strength.  In ancient India it was believed to offer protection from the destructive forces of other realms.
