Heart Chunky Huggie Hoop Earrings 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). • Color: Vintage Gold • 15 mm x 20 mm. • Gold-plated brass, gold-plated zinc, cubic zirconia. • Sterling silver posts are naturally soft due to the high silver content (just bend 'em back into shape if they get out of whack).
