Quartz is a completely natural material composed of a white or colorless mineral. However, its countertops are considered a man-made product, unlike natural stones such as marble, granite, and soapstone. It is also a relative innovation in artificial surface materials. It is a mineral found in harder stones like granite. The raw material for quartz is found in nature. Although there are many quartz crystals in nature, several are well-known, including Indian quartz, Brazilian quartz, and American quartz.
