It’s been quite some time since this job was completed…but that’s why traditional/transitional design is wonderful—it’s timeless! I’m quite certain it is a manufactured quartz and not natural stone. It is interesting to note that with the current situation—natural quartzite is pricing the same or less! You best bet is to go to a stone yard and look around— most also have slabs of manufactured materials as well. Also note —quartzite is stronger than granite and looks more like marble and hold up to heat unlike manufactured quartz
