18K Yellow Gold Spring Ring Clasp With Attached Jump Ring. Our 18K Yellow Gold spring ring clasps are great for all-purpose stringing in bulk designs. They are reliable and easy to work with for basically any necklace or bracelet, while being significantly cheaper than other clasps. This spring ring has a closed jump ring attached to it, which makes it ideal for stringing and wire wrapping. If you want to attach this clasp to a chain, you would need another open jump ring to connect them.
