Haden jewelry is made of raw brass and combined with natural fibers and leather. After sanding and filing, all brass pieces get coated with a metal protector to slow the oxidation process. Natural oxidation of brass is normal and creates a beautiful patina. Though this protective coating is not a fool proof method, if properly taken care of ***do not wear your jewelry in the water, spray perfumes or hairspray near it or get lotions or makeup on it*** the brass and the natural materials will stay looking nice for a long time.
If you have an ALL brass (NO fibers or leather) piece you can use a natural brass cleaner to restore its shine if that is the look you like.
If you have any questions or concerns please let us know.
