Fisherman's Ring

The Ring of the Fisherman is an official part of the regalia worn by the pope, featuring a bas-relief of Peter fishing from a boat. The ring is a signet used until 1842 to seal official documents signed by the pope, and has been a tradition for Catholics meeting the pope to show their devotion by kissing the ring. A new ring is traditionally cast for each pope, and the design features an image of Saint Peter and the pope's name in Latin. The ring is destroyed ceremonially upon the death of a pope to prevent the issuance of forged documents during the sede vacante.learn more on wikipedia
