Edward Teague's ring

This ring made out of a large gold band and a large amethyst. Edward Teague kept this ring while captain of the Misty Lady. It was unknown how Teague got this ring but it proved to be very useful. During the attack on the Misty Lady, Fitzwilliam P. Dalton III and young Jack Sparrow were locked in a gritty duel to the death until Teague steps in and uses the mysterious powers of the ring to make Fitzwilliam stop fighting and row Jack and Teague back to the Misty Lady. Teague later revealed that the ring could make anyone do what the wielder of the ring wanted. As a parting gift, Teague gave Jack his ring. Jack wore the ring for the rest of his adventures.
