NWT Madewell Mix & Match Earring Set Vintage Gold New with Tag Personalize your piercings with this set of four gold-plated brass solo earrings that can be worn together or separately (they're like sisters—each one is different but definitely related). Gold-plated brass, 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). Clean your jewelry after each wearing with a soft cloth. MA549 Shown with dime for size reference. No trades or modeling.
