Originating from the mountains of Iran, Pietra Grey is characterised by an even, compact appearance originating from the presence of elements such as coal and graphite: different shades of grey vary from light to dark in tone, giving depth to the design and infusing contemporary spaces with a sense of movement and elegance. Its reproduction in porcelain stoneware, in the Optimum Surfaces extra-large slabs, further elevates its versatility of use. Architects and designers the world over choose this effect for walls in luxury interiors and exteriors, as well as for worktops and decorative items.
