18K Gold Spring Ring Clasp With Attached Jump Ring. Our 18 karat 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 open jump ring attached to it, which makes it ideal for attaching to chains, wirewraps, and closed links. If you are in a pinch, you can use this spring ring for stringing jobs since the jump rings do not open easily, but best practice would be to use 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.
