Product Information Metal Finish: Gold PlatedSize Options: Size 8, 9, 10, 11, 12, 13, 14Additional Information Another term for gold bonded is gold plating. However, not all gold plating is the same. All rings are bonded with layers of gold, the first layers of pure 24k gold, the next layers of pure 14k gold. So, the concentration of gold on all of our products is a 24k concentration, yet with the highly marketable color of 14k gold. The gold bonding is done with exactitude in the United States to control its quality. Manufacturer is one of the few manufacturers in the country whose quality control standards of gold bonding meets or exceeds Federal standards. The inclusion of our Lifetime Certificate with each gold bonded piece is your assurance of our consistency in meeting these Federal standards.
