Red Goldstone is one of the few synthetic stones used in energy work and magic. It's red color comes from copper crystal structures in the stone which makes it an excellent transmitter of energy. The unique crystalline glass that encases the copper acts as an insulator protecting the energy being channeled or focused from outside forces. The red color lends this stone to being a wonderful tool in work involving love, lust, desire and passion. Also very effective for calming anxiety.
