❤︎ MATERIALS Chain: 14k Gold Filled Jump Ring: 14k Gold Filled ❤︎ SIZE 2mm Paper Clip Chain ❤︎ What is Gold Filled? My 14k Gold Filled chains are manufactured in the U.S and consists of 5% (1/20) solid gold pressure bonded over brass. They are tarnish resistant and perfect for those with allergies or sensitive skin. Gold-filled jewelry has 100x more gold alloy than gold plated and because that layer is so much thicker, it means gold-filled jewelry lasts longer and stands up to wear and tear bett
