We offer open and closed jump rings in multiple sizes and colors to match our chain. They are made from iron with plating and clear coating. Open jump rings can be twisted open and closed with jewelry pliers. Closed jump rings are soldered shut and cannot open. Attach to lobster clasps to finish a necklace, attach charms and pendants to necklaces and bracelets, or use to fix broken necklaces. The possibilities are endless. Fundamental pieces for jewelry making!
