Tiffany & Co Sterling Silver Return To Tiffany Mini Hearts On 925 Hook Earrings. The hearts are 100% genuine Tiffany's, "Return to Tiffany" was engraved on both sides, please note that they are mini hearts. The leverback hooks are not Tiffany's, but they are solid sterling silver and new.In excellent condition and look cute in person! As of today (11/24) I've used up all authentic/non authentic Tiffany's pouches. But i will pack them nicely in other pouch and box!
