Europa black pipe cut rings from Forever Metals. 9mm Width and high polished black finish. Black tungsten rings make fashionable wedding bands for men.
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.
