The black Diamond plate tungsten ring features a polished surface with matte background. The design is unique and perfect for those that want a non traditional ring style. The Diamond Plate ring also comes in standard polished tungsten.
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.
