The Krypton black tungsten ring is available in a 7mm width. The laser engraved Infinity symbol circles the ring in a silver engraving. In addition the ring can be made to order in any size, width and finish. Please contact Sales with any custom requests.
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.
Also available in Krypton 6mm Symbolic Infinity Rings.
