17, 18K yellow gold spheres set on sterling silver oxidized to dark gray. The cuff is just under 1 3/4 inches wide and conforms to the wrist. Each cuff is one-of-a-kind and has different sizes and placement of the gold spheres, shown here in the main image is #2 of 2. Edgy and modern, the versatile mixed metal design looks pretty worn with both silver and gold jewelry.
