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 metal inlay IS carefully pressed into the grooves and then shaved off flush to the ring surface. Black Zirconium is a very versatile metal that allows greater customization. Styles are available 4 to 14.5 in full, half and quarter sizes. Bands are comfort fit.
