Sterling silver-filled earwires are made of a durable outer layer of sterling silver surrounding a copper-alloy core. Finished with an additional silver plating for uniformity and an anti-tarnish coating to preserve the beauty. Fishhook earwires include a closed jumpring for attaching earrings.

For optimal results, use nylon jaw pliers when working with sterling silver-filled earwires to prevent scratching or marring. Contains 10% silver, 1/10 silver filled. Stamped ".925/10SF."
