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 countertops are resistant to heat and stains, and with proper sealing, is considered low maintenance when compared to other natural stones. Natural quartzite countertops are ideal for residential and commercial applications including kitchens and bathrooms. Quartzite countertop designs run anywhere from light, earthy hues to bold, dramatic veins.
