Did you know?

Signets have been used for thousands of years. The design of a signet is personalized for its owner, and no two are alike. The ancients used signets to mark their possessions and to sign contracts. In later years signets were used to stamp a blob of hot wax sealing a folded secret document so that it couldn't be opened and read without the design being broken. Nowadays you’re likely to hear of signets in reference to jewelry, especially [rings](https://bit.ly/3H9S6PH). The reigning pope wears one, called the [Fisherman's Ring](https://www.britannica.com/topic/fishermans-ring), which is carved with a figure of St. Peter encircled with the pope's name; after a pope's death, the ring is destroyed and a new one is made. If you guessed that signet and sign share an etymological relation, you’re entirely right: both can be traced to the Latin noun signum, meaning "a mark, token, image, sign, or seal."
