Elegantly formed and then gently hammered, these threader earrings are individually made by myself in the USA in my private studio. Argentium Sterling Silver is used for these earrings, which has increased tarnish resistance compared to traditional Sterling Silver. If you do notice your earrings tarnishing (sometimes starts with a slight yellow hue on Argentium), a quick wipe with a silver polishing cloth will bring your earrings back to their original bright shine. Made from wire that is slightly thicker than standard ear wire, these earrings may not be the best choice for sensitive ears or new piercings. Each pair of earrings come with two sets of complimentary rubber backers to help decrease the risk of losing the earrings during wear. The backers slide on easily with a slight twisting motion and gentle pressure.
