I am selling these because I don't use them. The ring on the front has a stone and is approximately size 9. The ring on the back is approximately size 7. Please check the images as I do not guarantee the sizes. The ring with the stone has a Swarovski crystal. The stone is loose in places, but I think it can still be worn without any problems. I will only sell to those who agree to no claims and no returns. Material: Silver
