Madewell Puffy Heart Hoops Earrings Color: Vintage Gold Made of gold-plated brass, these chunky huggie hoop earrings have a secret—you can wear them with or without the removable heart charms (which can double as pendants when added to your favorite chain). 15 mm x 20 mm. Gold-plated brass, gold-plated zinc Sterling silver posts are naturally soft due to the high silver content (just bend 'em back into shape if they get out of whack). New with tag, never worn.
