Start with a 10mm wide band of tough tungsten carbide. Add to that rich black tungsten and for the piece de resistance, a satin matte finish. The result is the Oxnard, bold sophistication at its best. Handsome and durable, the fade and tarnish proof properties ensure this ring will be the crème de la crème for many years to come.
