A unique collector for stones that are strongly distinctive, but intensely realistic at the same time. Leonardo uses all of its technology to develop stone-effect ceramic surfaces, diversifying not only the study of colours and aesthetic characteristics, but also the mixture of raw materials and ceramic elements. The creative source is nature, in all its power and distinctiveness. One, a unique set of distinct looks, expertly studied and reproduced on the surface of the full-body porcelain stoneware. It has a high technological content and offers the market a new format of 75×150 cm and its sub-multiple 75×75 cm, with two surface finishes: one version lapped gloss, and another natural with three different surface light refractions.
