    Sunstone

    Sunstone is a plagioclase feldspar, which when viewed from certain directions exhibits a spangled appearance. The optical effect appears to be due to reflections from inclusions of red copper.  Sunstone is rated between 6 and 6.5 on the Mohs hardness scale.  Sunstones are thought to promote positive expression, enthusiasm, self-esteem, sexual enjoyment and playfulness.
