This 14k real gold extender chain is crafted from solid 14k gold (58.5% gold) and is not plated or coated. It is nickel-free, lead-free, and hypoallergenic, making it ideal for sensitive skin. The highly polished, shiny surface resists tarnishing and will not turn skin green or red. Each piece is stamped with 14k, G14k, or AU585 to verify purity. The extension chain is small but strong, designed to lengthen necklaces, chokers, bracelets, and anklets. Available in 1-inch, 2-inch, and 3-inch lengths, it features a durable clasp for secure attachment. Note that this is a separate sale, not combined with other items. This delicate yet durable extender is perfect for everyday wear in any season. It is not suitable for very thick chains. Each piece comes carefully packed in a jewelry box, making it an excellent gift choice. Professional service ensures quality and satisfaction.
