This Black Zirconium band with exotic Kentucky Coffee Burl wood inlay is made to order. First, we precision grind a 5mm wide groove with a diamond coated grinding wheel. Then, the wood inlay is carefully inserted into the groove and coated with our proprietary formula, which protects the inlay from the elements. The inlay coating is then polished using high-speed buffing wheels and special polishing compound to achieve a highly polished finish. 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.
