This 8mm wide, hand-hammered densa cuff bracelet is now available in three sizes: small, medium and large. A size medium will accommodate the size of most wrists. Materials: Sterling silver (.925) or oxidized sterling silver. All materials are hypoallergenic. The black (oxidized) components of our jewelry will wear over time and eventually achieve a beautiful antique-like finish. This cuff bracelet was designed in San Francisco and is handmade in our Upstate New York production studio.
