This is a Tiffany ring I inherited from my family. It's quite old, so I think it's rare. It has "925.750" stamped on it, so the material appears to be silver and 18k gold. The exact size is unknown. Please refer to photos 6 and 7. If you need the exact size, please refrain from purchasing. Thank you for your understanding. I polished it, but it's old, so there are some fine scratches and dullness. Please also check the photos. I think it can still be used, so if you are comfortable with a used item, please consider purchasing. There are no accessories such as a box or bag.
