The most darling sterling silver puffy hearts for pierced ears marked Tiffany & Co. I wasn’t able to find another example of the same earrings online so it’s possible they are not original. They are marked Tiffany & Co .925 Mexico on the backs and the marking is different on each earring. I have found the same markings on pieces online. They polish up to an absolutely beautiful silver shine and are absolutely stunning! A great size measuring just under 1”H.
