This round copper jump ring is ideal for COPPRclay™ designs and it looks good in multi-metal jewelry. Create chain mail designs or attach charms, pendants or drops with the ring. Jump rings are made from coiled wire and have an opening that allows you to insert it through a ring, loop or hole on another finding. A staple of the jewelry-making industry, these rings are ideal as attach rings for component designs, as strand or chain ends, and as links for creating chain. Solder rings closed to ensure that connections are permanently secure.
