Quartz is a great option for countertops. They come in a large variety of colors and patterns not found in nature. They are consistent and non-porous. Quartz is a perfect option for those who would like a marble look but do not want the maintenance of a marble counter. They can still scratch or chip like natural stone but are very durable under normal use. Quartz countertops are man-made engineered stone countertops formed by combining 90% ground quartz (a natural hard mineral) with 10% resins, polymers, and pigments. This forms a very hard non-porous surface. The appearance depends on how the quartz is ground: coarsely ground quartz produces a speckled appearance, while finely ground quartz produces a smooth look.
