The surface of this plain round signet ring measures 20x20mm (roughly the same size as a U.S. nickel) and makes for an excellent option as an oversized men's signet ring. With its large size, it is a quality piece that is ideal to be given to a man as a gift idea that can be engraved and personalized, or simply as a standalone piece. Signet rings have a long tradition as heraldic jewelry that celebrates oneself or one's family.
