Lenova's new Cobblestone Green Onyx sink is an unforgettable addition to the bath. Sparkling with elegantly inlaid green onyx, each sink is an original work of art. To craft the sink, a master stonemason begins by using a centuries-old cobblestone for the outside of the vessel. The cobblestone shell is then hollowed out to form a bowl. Using a food-safe, knife-grade epoxy, green onyx chips are adhered to the bowl’s interior in a mosaic pattern. Once the epoxy hardens, the onyx is smoothed and polished, leaving a gem-like interior. The sink measures 16 in. x 16 in. overall and the bowl dimensions are 14 in. x 14 in. x 5 1/2in. The sink weighs 90 pounds and retails for $665.
