The Metis is a high polished facet tungsten ring for men. The comfort fit design is slightly curved on the inner diameter for a pinch free fit. The Metis is commonly worn as a wedding band however many wear it for fashion as well.
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.
