Soldered closed sterling silver-filled jump ring mix is made of a durable outer layer of sterling silver surrounding a copper-alloy core. These items are 10% sterling silver, making them 1/10 silver filled. Jump rings have additional silver plating for uniformity and are completed with an anti-tarnish coating to preserve the beauty. Jump rings handle like sterling silver. Sizes include rounds ranging from 4-10mm. Jump ring size, gauge and inside diameter are approximate.
For optimal results, use nylon jaw pliers or pliers dipped in Tool Magic® heavy-duty rubber coating when working with sterling silver-filled jump rings to prevent scratching or marring.
