This lightweight and durable jewelry extender chain is designed to lengthen necklaces, chokers, bracelets, and anklets for a perfect fit. Crafted from real 10k gold (41.7% gold content), it is nickel-free, lead-free, and hypoallergenic, making it safe for sensitive skin. The highly polished surface resists tarnishing and won’t discolor your skin. Available in 1-inch, 2-inch, and 3-inch lengths, each extender features double spring clasps for secure attachment and easy use. Note that this delicate chain is not suitable for very thick jewelry. Sold separately, it comes in an elegant jewelry box, making it a great gift. Look for the 10K G10K AU417 hallmark for authenticity.
