When you want to change up your look, why not use an extender chain to increase the length of your necklaces so that they can be worn no matter what the neckline on your outfit? The 3mm wide curb chain secures to both ends of your current chain necklace (or bracelet) using the bolt ring clasp and adds between 2 and 4 inches extra, depending on the option you select from the drop down menu. These extender chains are made from rose gold plated sterling silver, but we stock silver and yellow gold plated versions too.
