This 3mm wide black and gold cuff is now available in three sizes: small, medium and large. A size medium will accommodate the size of most wrists. Materials: 14k gold or rose gold-fill (14k gold over brass core/no nickel) and oxidized sterling silver (.925). All materials are hypoallergenic. The black (oxidized) components of our jewelry will wear over time and eventually achieve a beautiful antique-like finish.
