Trending: The Boom of Quartz Countertops
The Boom of Quartz Countertops. Quartz is one of the most common minerals in the Earth’s crust. It is found in all forms of rock: igneous, metamorphic, and sedimentary. Quartz is physically and chemically resistant to weathering. When quartz-bearing rocks become weathered and eroded, the grains of resistant quartz are concentrated in the soil, in rivers, and on beaches.
