The Carre plate, with its clean parallel lines and uncomplicated shape, provides endless versatility. Add the Bordeaux crystal knob, with its traditional circular shape and a flat outer surface that magnify the intricate facets underneath, and you will enjoy a combination with an unrivaled style. All Grandeur crystal knobs are created from lead-free crystal for unparalleled clarity and beauty and are mounted on a solid (not plated) forged brass base.
