After browsing our ever-changing selection of 14k solid gold / white gold, 14k gold / rose gold filled or sterling silver, each chain is cut to your exact/desired measurements (wrist, ankle, neck) and secured with a gold ring that is welded with a small zap. This leaves you with a clasp-less piece that is light and airy yet strong enough for daily wear. However, being permanent does not mean indestructible. Fine and demi-fine jewelry has its limits. It all depends on your lifestyle. For many, a chain can last a lifetime...or however long you wish.
