This is most certainly true. However not all granite is the same. I'm from Atlanta originally. The granite there is a very uniform mix of quartz and mica. It's the stuff you see in everyone's driveway, up there at least. That was really what I had in mind not the stuff that you see in most people's kitchens. That north Georgia granite is not colorful enough for most people to use for countertops but it is probably more uniform than an Arkansas stone.
