Quartzite, also known as Luxury Stone in China, is a naturally occurring metamorphic rock. It is created when sandstone is subjected to extreme heat and pressure caused by tectonic plate compression in the crust of the earth. The stone is mined and sawn into slabs which are later precisely cut to become countertops. The tops are polished and sealed for beauty and durability. Quartzite is a decorative stone and may be used to cover walls, as roofing tiles, as flooring, and stairsteps. Its use for countertops in kitchens is expanding rapidly. It is harder and more resistant to stains than granite.
