Jump rings are essential jewelry findings for any jewelry maker who is planning on attaching a clasp to the piece, or other decorative aspects. They are made from round wire and are used to securely attach pieces of jewelry together, such as a clasp to an end cap or attaching beads to bead findings. The unsoldered gap in the wire loop is where you would loop the item you’re attaching through the ring, then close with a pliers or solder shut.
