Star Ruby and Star Sapphire

Some rubies and sapphires have tiny needle-like inclusions oriented along their crystal faces. When cut in a high-domed, en cabochon shape, they display a dancing, six-rayed star. The star moves across the face of the stone with shifts in light, an effect known as asterism. The star sapphire was particularly prized in ancient times as it was considered a talisman and a guiding star for travellers. Sri Lankans believe that a star ruby protects the wearer from witchcraft. It is considered so powerful that even when the original owner passes the stone to someone else he continues to receive its protection.
