The rhinestones are missing or dirty. They are from about 20 years ago. The earring backs were used haphazardly, so I don't know if they are the original ones. Please refrain from purchasing if you are concerned about this. These are heart-shaped sling earrings that I fell in love with at first sight and purchased at the Chanel store in Osaka. There is no guarantee card. There is a hallmark. Length: 2cm Measurements are approximate.
