Crystal Grey, a very hard and strong natural stone, is a Quartzite standing out for its delicate chromatic variations and for its extremely elegant appearance. The background is a soft mix of grey crossed by irregular shaped brown veins, creating a very soft and refined cloudy texture. The peculiarity of this slab is in its composition: the background is crossed diagonally by dense dark deep veins while, on the contrary, more superficial horizontal light cream veins emerge.
