To open jump rings correctly, grasp one side of the ring with bent, flat, or chain nose pliers, positioning the ring so the opening is up. Using another pair of pliers, grasp the other side of the ring directly opposite the first pair and slightly twist one hand toward you and the other hand away from you to create a gap in the ring. Reverse this process to close the ring. You may need to gently wiggle the ends a bit until they form a flush seam.
