Change the length of any sterling silver necklace by adding this popular extender! Add a total of 3 inches to an existing finished necklace to allow more versatility to its length. When not in use the extender hangs down the back of the wearer, so add a charm or pendant to really make it unique. Match the neckline style with the necklace length in our helpful article: Necklace Lengths Guide - How to Measure & Choose a Necklace Length.
