Quartzite is a natural metamorphic rock formed from sandstone that has undergone immense heat and pressure within the Earth’s crust. It is composed primarily of quartz, which gives it its durability, hardness, and distinctive appearance. Quartzite is renowned for its beauty, strength, and versatility, making it a popular choice for various architectural and design applications. Quartzite is one of the hardest natural stones available, surpassing the hardness of many other popular countertop materials like granite and marble.
