Because granite, marble, travertine and limestone are natural products, not man-made, some degree of variation is to be expected and even welcomed. Indeed, this is the beauty of natural materials whatever stone you choose will be absolutely unique. Some stones show more variation than others, and even these are selected for a range that most richly represents that particular stone. We encourage our customers to personally select the slab(s) that will be used for their project. Thats why we have eight Intertile locations to serve you.
