All of our products are bonded with 50 layers of gold, the first layers of pure 24k Yellow gold, the next layers, 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 Yellow gold. All gold bonded products are manufactured with exactitude in the United States to control their quality. The manufacturing process is from one of the few companies 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 Federal standards.
