7mm flat Tungsten band with grooved edges
and a 1mm center groove in a satin and polish finish. The two raised bands of the ring have a satin finish offering subtle contrast to the high-polish grooves. Our tungsten men's rings boast the most scratch resistant surface of any performance metal, meaning that you no longer need to determine the metal type of a mugger's grill before you punch him in the teeth. Lifetime Guarantee.
