Onyx is not a new stone; It is actually millions of year old! A natural process of heat and pressure creates a crystalline stone rich in color and pattern that reaches well below the surface to reveal a truly unparalleled inner warmth, depth and opalescence. One of the ideal applications of the honey onyx stone is carving sinks. All of our honey onyx stone sinks are hand-carved and polished. As such, every piece of honey onyx stone sink is unique given its individual nuances.
