Jumprings

Also called broken rings or connector rings, junction rings are jewelry primers used to assemble and connect elements together. They are useful for connecting a pendant to a chain, a clasp to a bracelet, a mini charm to a customizable ring, a charm to earrings or different parts of a piece of jewelry.

To open a ring, you can use flat-nose pliers. There are also specialized pliers for opening double rings, which are sometimes harder to handle.
