We thought this little white gold heart was filled with square cut pieces of onyx. It wasn’t until the light hit it for the photo shoot that the deep blue color snapped on. We took the piece into Rue’s Upper East Side jeweler and, sure enough, these are gorgeous, fine dark sapphires! He told us he’d be selling it for a lot more than we’re asking in his store (but, come on, that’s the Upper East Side!) We will find one of Rue’s silver or white gold chains to hang this on for you and include that with the pendant, too. Also comes with a Certificate of Authenticity from Estate of Rue.
