The Hercules features a black ceramic textured inlay that is a stark contrast against the polished tungsten. Black ceramic inlays are durable and maintenance free. The Hercules inlay is solid and not plated to eliminate scratches or fading.
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. Ships fast and free every day.
