This is Onyx... Also known as Onyx Marble, this translucent stone is celebrated for its unparalleled beauty, character, and ability to fuse nature and design into a work of art. A compilation of spring water, calcite crystals and other minerals that over time, form color bands that are layered as if intentional, but like snowflakes, no two pieces are exactly alike. Because the surface can scratch and etch, Onyx is seldom recommended for busy kitchens or heavy traffic areas. Vanities, bar tops, and accent lighting are some common applications, but Natural Onyx is sure to grace most any desired space. Imagine. Design. Create it.. with Stone.
