This rare coin is mounted in an 18-karat gold ring set with 14 genuine diamonds with a total weight of 0.22 carat. The Himyarite Confederacy ruled Ancient Yemen, an important stop on the trade routes to India. Though never conquered by the Romans, their coinage reflects a Classical influence. This extremely concave coin, base on Athenian prototypes, bears the portrait of a beardless man who resembles the Roman Emperor Augustus. Even in a world that seems as far away to our age as Classical Antiquity, this was a token of distant, exotic, and mysterious place. Jewelry such as this is for those who can appreciate the unusual.
