Europa cool tungsten carbide rings for men and women with an extra wide 12mm width. Forever Metals Europa features a comfort fit for all day continuous wear.
The Metal that is used is a Nickel Binder that is higher in quality in comparison to cobalt. Cobalt is a inferior binding agent which may darken the color of the ring over time. Cobalt is most common in lower cost tungsten rings. This is due to the rings being mass produced in countries other than the United States.
