This is a beautiful piece of jewelry. It is an 18″ white gold chain with a 3/4″ diamond covered heart shaped pendant. The heart opens though, does that mean it would actually be called a locket? Anyway, we thought it was possibly covered with diamond chips or a pavé setting, but Rue’s Upper East Side jeweler pointed out that these are each individually prong set diamonds – there are about 50 of them on the 14kt white gold heart. Comes with a Certificate of Authenticity from Estate of Rue.
