This dramatic cuff is made from steel that has been given a black patina. The edges of the cuff have been textured to give it a slight ruffling effect and then 18K gold has been fused along the edges of the top and bottom. The cuff is then given a protective acrylic finish on both the front and back to prevent rust. If the cuff does get wet, just dry it off and you're good to go. However, I wouldn't recommend wearing it a spa or pool! The round pieterisite stone with lots of gold tones is a lovely complement to this cuff. The stone has flashes of brown, black, a little red and lots of amber tones. The bezel for the stone is made from 14k gold fill. The cuff is about 1 1/4 inches wide and would fit a small to medium wrist. It is oval shaped to prevent it from spinning around your wrist. While there is some flexibility to the cuff, it is minimal and not recommended that you repeated squeeze it or pull it apart. Although it isn't possible to duplicate this exact cuff or stone, custom orders can be done in your size or with a stone of your choice.
