Ceramic Couture™ wedding bands are made of a hi-tech aerospace material. This permanently polished jewelry is lightweight, colorfast, and heat resistant. Available in pink, white, and black colors. Clean with soap and hot water, alcohol, or a steam cleaner. Do not use any other cleaners or chemicals for cleaning your ring. The potential for cracking does exist, so keep your ring away from extreme forces. Your jeweler may polish any gold and silver inlays. Ceramic can be removed by cracking the ring into pieces with the exclusive Ring Cracker your jeweler uses.
