It is a particularly luminous quartzite, coming from Greece, reproduced by the porcelain stoneware tiles, Oros Stone by Ergon, characterized by the presence of microcrystals capable of infusing the surface with ever-changing plays of light. The series available in six colors - White, Sand, Greige, Gray, Sky Blue and Anthracite - is enriched by the innovative Multi Prestige Brecciato, a modular proposal made up of nine different formats with "broken" contours, which recreate the effect of stone to “split” to be creatively laid to obtain a natural effect with great expressive power. Three surface finishes, Naturale R10, Tecnica R11 and Splitstone, a 3d wall decoration that combines the three-dimensionality of the volume together with the graphics dedicated to interlocking the structure.
