Multiple finishes and a carbon fiber inlay give this 8mm comfort-fit ring a futuristic look. One of our newest men's cobalt chrome rings; it features a black inlay of carbon fiber surrounded by a satin-finished face and highly polished step-down edges. Known for its premium bright white color and scratch resistance, cobalt chrome is a popular choice for men's fashion rings and wedding bands. Comfort fit rings usually measure 1/2 size smaller due to the additional metal inside the ring. We recommend having your finger measured for a comfort fit ring at your local jewelry store.
