Fashioned in black tungsten, this 6. 0mm-wide wedding band features a brushed finish with polished flat beveled edges. 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. Tungsten rings cannot be resized after purchase. Previously owned treasures are from both guest returns and through our stores trade-in policy. All previously owned items have been cleaned and restored to their original beauty, just like new.
