This cobalt concave chrome wedding band is 8mm wide and features two grooves bordered by a brushed center section and highly polished beveled edges. The two grooves are accented with black enamel, and the contrast of the dual finish and clean black stripes results in a striking appearance. The hardness and durability of cobalt chrome, along with the natural premium white color, makes this band a great choice for those looking for a wedding band made of a contemporary metal.
