The materials specified in a project can reveal several details about the job—site location, client type, and how the space will be used. A natural stone, marble is a material for the ages. It has been used in buildings as geographically diverse as the Taj Mahal and the Washington Monument. Arizona Tile’s Calacatta Gold is sourced from Italian quarries and cut into 2"-diameter hexagons, 12" squares, and 12"-wide-by-24"-long rectangles. Pencil-thin black veining contrasts the marble tiles’ thick strands of gray and its white background.
