Sunstone is a great stone for the Base, Sacral and Solar Plexus Chakras, but can clear and energize all Chakras. Sunstone was used by the Canadian Indians in medicine wheel rituals, by the ancient Greeks to represent the Sun Gods, and in ancient India for protection from dark forces from other realms.
Physically, Sunstone can aid in Depression and SAD (Seasonal Affective Disorder). Sunstone is the yang which balances the yin of Moonstone, and when worn together these stones work in beautiful harmony.
