Cliffstone is the interpretation of a rocky stone that does not exist in nature but has been reinvented creatively by Lea Ceramiche. Stone effect tiles that reproduce the veins and characteristics of stone. Different veining for each individual piece, artificial markings that overlay the consistency of the material.
