This is a Tiffany ring. My wife bought it at a Tiffany store a long time ago, but she didn't use it much and kept it at home. She seems to have forgotten the size, but the diameter of the ring's hole is 1.7cm. It comes with the box and a pouch for accessories. ----------------------------------- The number of characters in the product description has been exceeded, so I cannot write everything here.
