Artisans craft each of these napkin rings by hand, using techniques passed down through generations. Their rich colors, subtle shading and fine details are created through cloisonné, an ancient metalworking technique where “cells” (cloisons) of copper wire are filled with colorful glass enamels and fired in a kiln. Approx. 4" long. 1 1/4" diam. rings. Set of four. A Williams-Sonoma exclusive. Made in China.
