18K yellow Gold Cartier Love band. Not to be confused with the Love Ring, which is a little bit thicker in diameter than the band. Purchase in September 2022 while on Vacation and has minor scratches from wearing. These pieces scratch Easily. Not worth buying new in my opinion anyway. This is a great deal. Receipt on photos. 100% authentic comes with box and authenticity card. tried to take a great picture of the serial number engraved on ring. Please let me know if you can’t see it.
