The Neptune 6mm mens tungsten wedding bands features a redwood inlay circling the tungsten ring. The Neptune is a comfort fit and comes in widths available for both men and women. The ring can be personalized with engraving or outer diameter knot work.
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.
