Handmade by Kara Douylliez. The stone is Swarovski and the vintage inspired band is 100% brass. The crystal has a diameter of 14 mm and the height of the ring is 10 mm {from the base to the top of the ring}. The rings have been sealed, but you should avoid getting them wet to keep the brass from tarnishing. The rings are adjustable. We have a small selection of these gorgeous rings. New, not vintage. Free shipping.
