hammered open circle studsSimple and classic, these 14k gold fill or sterling silver hammered hoop studs have that slightly imperfect shape that comes from being made by hand. Sterling silver posts and earring backs. Nickel free. 14k gold fill items are not plated. There is 100x more gold in gold fill wire than in gold plated wire. The color is the same as solid gold, it has the same tarnish resistance, and it is safe for sensitive skin. It won't wear off or flake like plated
