NuGold is a brass alloy that has been specially formulated for jewelry and is also known as "Red Brass," "Merlin's Gold," and "Jeweler's Bronze." It has a rich warm color and if polished resembles gold without the high cost of gold. Nu Gold contains 85% copper and 15% zinc and no nickel. It tarnishes considerably slower than copper, and is easy to clean.
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 ounce (oz). Occasionally you might get a misshapen ring or an end cut half ring. To account for this, we put extra rings in every bag. If you need to know outside diameter or need the ID in inches, please contact us.
