Our jump rings follow the American Wire Gauge (AWG), also known as Brown and Sharpe (B&S). All sizes listed are inside diameter (I.D.), measured in millimeters which corresponds to the size of the mandrel onto which the wire is wound. Use these I.D.'s as a guide not an absolute. Rings are sold by the troy ounce (ozt). Occasionally you might get a misshapen ring or an end cut half ring. To account for this, we put extra rings in every bag.
Please check our return policy before purchasing silver filled jump rings.
