ENIGMA | Tungsten Ring Black DomedDomed Black Tungsten Ring with Brushed Cross Alternating Diagonal Cuts Pattern 8mmThis bold, masculine and enigmatic Black Tungsten wedding band is brushed finish and crisscross groove pattern. Because Tungsten is a harder metal than others, it cannot stretch, and cannot be resized. If your finger size changes, you will need a brand new ring.
