This cobalt blue knob will make your special cabinets, dresser drawers, or desk pop! It is made from Lapis Lazuli, a stone known to encourage spiritual honesty, communication, and intellectual acuity. SDE's stone knobs are unlike any other, with all finishes handmade over a base of heavy solid brass. You will feel the quality in the weight of the knob. The stones are professionally cut and set to last.
