Grey Stone, native to the mountains of Iran, offers a uniform, compact appearance from charcoal and graphite, with shades of gray ranging from light to dark, lending depth to design and elegance to contemporary spaces.
Its faithful reproduction in porcelain stoneware, in Optimum Surfaces’ large slabs, amplifies its versatility.
Global architects and designers choose this effect for luxury, interior and exterior wall coverings, countertops and decorative objects.
