Gold is a color that pairs well with rich jewel tones such as Amethyst and Emerald, even Onyx! Gold filled clasps are actually made using 14 karat gold bonded to base metal, so you will get the luxurious feel of pure gold when you use these clasps and toggles in your jewelry designs. Want the look of gold without the luxurious price tag? Try gold plated clasps. They have a base metal - usually of pewter - with a thin layer of gold plated on top. No matter which option you choose, gold will always lend elegance and timelessness to your designs.
