ca. 100–300 AD. Roman. A gold ring with a circular band, flared shoulders, and a circular bezel set with a carnelian gem; the beautiful intaglio portrays a male figure in left profile; the diadem in his hair and the lightning bolt on the left-hand side may suggest that this is a portrait of Jupiter (also known as Jove), the Roman king of the gods. The item has undergone X-ray fluorescence analysis to confirm the metallurgical content suggesting its ancient origin and lack of modern trace elements. This analysis will accompany the purchase.Provenance: From an old British collection formed in the 1990s; previously acquired in Germany.Size: D: 18.8mm / US: 8 7/8 / UK: R 1/2; 6g
