Quartzite is a metamorphic rock formed from Sandstone. It is a very hard and strong rock, and finds its use in countless places within the construction industry. This natural stone has a very detailed crystalline structure, which grants it a slightly lustrous and very rich appearance. Since the crystals of Quartzite are very tightly packed, Quartzite acquires a very hard, angular surface. The stone is very strong and withstands heat and pressure without breaking or chipping. Quartzite never erodes or weathers because of its crystalline structure.
