Tiffany and company knot ring-yellow gold

Authentic Tiffany and company yellow gold knot ring. Ring has slight bend in the band as shown. However this can easily be taken if to Tiffany to be fixed. Amazing condition otherwise. Definitely still wearable. Comes with ring case and box. Size 7.5 There is a marking but it is very hard to see Tiffany and co au750. I am the original purchaser and owner so it is 100 percent authentic. Any questions ask. Price reflects photos
