As ancient as the moon itself, Rainbow Moonstone holds the power of mystery and is thought to be an amulet of protection for travelers and those on an inward journey. Moonstone occurs in delicate shades of peach, blue, green and white in a prismatic nature. A large 10mm x 18mm Rainbow Moonstone shimmers in an ornate 925 Sterling Silver filigree setting. Due to the nature of the gem, variations in color will occur.
