This 14k gold extender chain is crafted from solid 14k gold (58.5% gold, marked 14k/G14k/Au585), not plated. It is nickel-free, lead-free, hypoallergenic, and features a highly polished, shiny surface, ideal for sensitive skin and will not cause green or red discoloration. The durable yet delicate chain lengthens necklaces, chokers, bracelets, or anklets. Available in 1, 2, 3, 4, or 5-inch lengths, each features a double spring clasp for secure, easy attachment and removal. Note the extension chain is small but strong, sold separately; check style and length before purchase. It may not suit very thick chains. Perfect for everyday wear year-round. Packaged in an exquisite jewelry box, it arrives protected and ready for gifting.
