Tiffany ring

The ring was bought four years ago at Tiffany. Wear for about a year. Rose gold. If you are willing to buy, please confirm that you know I may not find the box and receipt, and do not mind this matter. I'm not really in the habit of keeping the box. I forgot the number of the rinforI guess it should be size 6. It is for women. if you want to buy it, I can go to the shop and ask for it.
