Polished to a mirror-like shine, this classic domed style is a one of our most enduring styles among men's tungsten wedding bands. Made from tungsten-carbide, it is stronger and more durable than most other metals, and it has the timeless and classic design that men crave. It is 7.7 mm wide and cobalt-free. The inside edges are rounded for a superb fit. Comfort-fit rings should be ordered 1/2 size smaller!
