A highly polished center groove adds dimension to this black men's seranite wedding ring. Unlike some other black metals, ceramic-based seranite is naturally black so it won't fade, scratch or discolor. Men love the durability and style of this sleek 6mm wedding band.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.
