This is a very pretty vintage English sterling silver puffy heart charm with a daisy floral design on both sides. It measures 3/4" long with the bail ring by 5/8" wide by 1/4" in thickness and tested as sterling silver and has a high polish finish. After some research I believe this charm to be 1960s. It can be worn as a necklace pendant or on your bracelet as a charm. Much prettier in person.
Thank you for looking!
