This double strand, black, gemstone bracelet is a medley of asymmetrical stones, rondelle stones, and hand-forged, large links. It is comprised of black spinel and sterling silver. The metal has been slightly darkened for a vintage patina and shined for a slight sheen. ALL metal is solid, sterling silver 925. Please indicate your precise wrist size upon purchase. To determine your correct size, measure a flexible tape measure around the circumference of your wrist bone. Because of the toggle clasp, a proper fit is contingent on your accurate size. We use two bracelet sizers to ensure that you will receive an optimal fit.
