Noble Stone is a marble effect porcelain tiles offer an interpretation of some of the most exquisite limestone formations the world has ever seen, capturing the luxurious look and nuanced colors found in nature, such as the warm white of the Dover Cliffs, the intense ivory of the Pamukkale Limestone Terraces in Turkey, and the rugged limestone formations within the caves of Luray in Virginia. The 3D Satin finish is a unique “soft-touch” effect on the surface enriched with veins engraved in bas-relief.
