This Black Zirconium band with rose gold inlay is custom made to order. First, we precision grind the groove with a diamond coated grinding wheel. Then, the precious Metalinlay IS carefully pressed into the grooves and then shaved off flush to the ring surface. Black Zirconium bands begin as a light-gray Metalsimilar to titanium. The black color is achieved by heating the Metalto a certain temperature. Once the Metalhas been oxidized to black it is much more wear resistant than in its natural state/color.
