The signet ring is one of the oldest forms of personal jewelry. In ancient Rome and Greece, they were worn as seals of identity, pressed into wax to authenticate documents and mark ownership. They were objects of power, worn by people who understood that what you chose to carry on your body said something about who you were. The Common Era rings collection works within that tradition. Goddess rings cast with portraits of Athena, Aphrodite, Artemis, Hecate, and Medusa. Zodiac signet rings engraved with alchemical seals drawn from a 17th-century manuscript. Portrait signets of historical women including Anne Boleyn, Boudica, Hypatia, and Sappho. Ancient-style talisman and amulet rings engraved with protective symbols from Egyptian, Roman, and Gnostic traditions. Heirloom rings set with ethically sourced sapphires, diamonds, garnets, and moonstones. Unique rings grounded in genuine historical research, made to order in solid gold in New York City.
