Cartier Pt950 Engraved Ring with 2 Diamonds I purchased this here. It has been resized to a size 9. Therefore, the Cartier engraving on the inside is said to have disappeared, but the serial number is engraved. It's a lovely Cartier platinum diamond ring. The diamonds sparkle beautifully. There are also some minor scratches, but I will sell it to someone who understands this. Please note that this sale includes only the box and the ring.
