A signet ring is a type of ring that features a flat surface, often engraved with a design, symbol, or initials. Traditionally, it was used to seal documents, leaving an impression in wax to authenticate the sender's identity. Signet rings have been worn by royalty, nobility, and individuals of high status throughout history. These rings are typically made from precious metals like gold or silver and can be adorned with gemstones. Today, signet rings are often worn as fashion accessories or family heirlooms, representing personal or familial heritage, and are sometimes passed down through generations.
