Gold plated brass is 24K gold plated over solid brass. We use 24K gold and have adjusted the color to resemble 14-18K. Our gold plating is of high quality and nickel, lead, and cadmium free. Care: Do not wear in water or when exercising. When not wearing your piece, it should be placed in our cotton anti-tarnish pouch. To clean, use a dry cotton cloth to gently buff your piece. Do not use jewelry cleaners on gold plated brass pieces.
