These gorgeous 3.5mm gold filled or sterling silver heart studs are dainty and oh so cute. Great for a little girl or your second hole to wear with our Everyday Hoops. They are gold filled and hypoallergenic- gold filled means that they will wear just like solid gold earrings. No sensitivity to the metal, no tarnishing- just put them in and leave them in! They are simple enough for every day wear with just enough flare to wear for an evening out.
