Exchange vows on your wedding band with a ring he'll adore. Crafted of tungsten carbide and 18k white gold, this simple 7. 0mm wide band is magnificent with a single diamond accent bezel set at the center along a stain-finished tungsten stripe. The inside of the band's shank is rounded for comfort. Tungsten carbide is a true innovation in jewelry. Tungsten is virtually impossible to scratch and is much heavier and denser than gold. Metal gram weight varies based on the ring size selected. This ring is only available in size 10. Tungsten rings cannot be resized after purchase.
