1920s “M.O.” Signet Ring


Over the course of the 19th century and into the 20th, the signet ring evolved from a functional piece of jewelry - a family crest used to seal letters with wax - to a less formal piece of jewelry designed for everyday wear. This signet ring with Birmingham hallmarks that date it to the year 1929 is engraved "M.O."
