Limestone is a natural stone highly appreciated not only for its resistance, but also for its monochrome and subtle light-toned veins which make it versatile and transversal in architectural designs. The colors, white, beige, grey and black, derive from different geological formations of the countries which they come from: the brilliance of Italian white limestone, the golden shades of French stone, the authenticity of English stone, and the elegance of Belgian black stone, faithful reproductions of the original sedimentary rocks.
