These are AA Grade, free form faceted Amethyst gemstones dangling from sterling silver bails. These bails have just a hint of rhodium added to them. The addition of rhodium slows the tarnishing process, less polishing for you. These free form Amethyst stones average 16 x 12mm in size, not including the bail. No two pendants are exactly alike in size or shape. Amethyst gem stone beads are said to bring about courage and inner strength. They have been used to protect against psychic attacks. On the spiritual level, the amethyst stone helps open to communication with angels, telepathy and other psychic abilities.
