Quartzite is a strong and durable stone that is a popular countertop surface choice. When sandstone is heated and pressurized, it converts into quartzite stone slabs with quartz pieces that emit a decorative crystalline appearance. Quartzite kitchen countertops are resistant to heat and stains, and with proper sealing, lower maintenance than other natural stones. Quartzite countertop designs run anywhere from light, earthy hues to bold, dramatic veins. Natural quartzite countertops are ideal for residential and commercial applications including kitchens and bathrooms.
