A signet ring is an engraved ring, usually gold, with the initials or family crest of the owner.
From ancient Rome on, these rings have been used as a signature stamp; a symbol of membership in an organization or family.
The culture and traditions of the wearer determine which finger the ring is worn on. The time it was made can determine how elaborate or simple the design is.
Signet rings are often family heirlooms, handed down from generation to generation, but there are still jewelers trained in making authentic signet rings.
