A great alternative to granite, marble, and other more popular stone surfaces, onyx provides a sleek and modern look to any workspace. Onyx is formed in caves as stalactites and stalagmites drip to form this precious stone. Onyx Countertops are a rarity as they bring a unique appearance with strikingly dramatic appeal. Not often placed in a horizontal orientation such as a countertop, onyx countertops are a unique and premium surface. With its exclusive style, onyx generally comes in swirling and pastel color patterns. We offer over 10 onyx color choices of this exceptional stone, in-stock and ready to be delivered for your unique project surfaces.
