This 14K real gold extender chain is crafted from solid 14K gold (58.5% purity), not plated or coated. It is nickel-free, lead-free, hypoallergenic, and highly polished with a shiny surface, making it ideal for sensitive skin without causing discoloration. Each piece is stamped with 14K, G14K, or AU585 to verify authenticity. The durable yet delicate chain is perfect for extending necklaces, bracelets, anklets, and more. Available in lengths from 0.5 to 5 inches, it features a secure lobster clasp for easy wear. Note that the extension chain is small but strong and sold separately—check the style and length before purchasing. It is not suitable for very thick chains. Packaged in a protective jewelry box, it makes a great gift. Wear it year-round for a stylish and adjustable jewelry solution.
