Quartzite

Although many people often confuse granite with quartzite, on the contrary, quartzite, like marble, is a metamorphic rock, rather than igneous rock like granite. Extremely hard and compact, of a finer grain than granite, exotically veined and colored like marble, quartzite is the most versatile stone amongst all of the natural stones. Stronger than marble and even granite, quartzite is actually the most durable natural stone. In fact, quartzite can be called nearly indestructible, resistant to chemical weathering, non porous, scratch resistant, and hard as diamonds, quartzite is easy to maintain and keep bacteria-free.
