This 14-karat white gold spring ring clasp features an open perpendicular ring for tying off strands. A classic clasp, the spring ring is ideal for all but the heaviest of necklaces. A spring ring is simply a hollow ring with an opening in one side that is closed off by a sliding 'door' inside the hollow ring. The door is held in place by a tiny spring controlled by a tiny nib on the outside of the ring. Press the nib back to compress the spring and open the clasp; release it to close the clasp. This clasp is plated with rhodium to ensure a durable, tarnish-resistant finish.
