Marble Pietra Grey tiles in size 80x40x1,5 cm honed finish. Pietra Grey is a stone with a homogeneous dark grey background and occasionally marked by defined and subtle white veins. The white crystalline filaments, like lines that furrow the anthracite-colored background, create extremely refined patterns. In honed finish the ambience turns to a warm grey color with defined white veining. Right now in rough finish.
