The sterling earwires on these earrings and hand made by our silversmith in Istanbul. The delicate handwork in the hearts is truly amazing. These earwires are not cast, instead, each piece is made entirely by hand. The earwires are attached to lustrous freshwater pearls, which are capped with a hand-made sterling silver cap. The earrings hang 1 and 1/2 inches and come with rubber backs for security.
