The Mason Black Metal Tungsten Rings in a Dome 9mm Width. The Black pattern circling the ring is similar to a Damascus Style Ring. Mason also available in a matching womens.
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.
Mason is available in 6mm black flat unique ring style.
