To make this ring, we took a Tungsten Carbide ring and added black elements and high polished tungsten inner band. Just a handsome ring that looks great on any man, goes with anything, fits any occasion, and can accommodate any budget. Comfort fit tungsten rings usually run 1/2 size larger, it is suggested you buy a half size smaller than your standard ring size. We recommend having your finger measured for a comfort fit ring at your local jewelry store for an accurate fit. This ring is not eligible for return or exchange if engraved.
