A quartz kitchen countertop is one of the most durable countertops you can buy today. Quartz is a natural crystal, and more precious varieties are cut into gemstones. Like marble and granite, it’s mined from a quarry. An additional manufacturing process is required to make quartz into a countertop, as quartz can not be mined in the sizes required for a countertop like granite or marble. Crushed quartz is mixed with about 7% polymers, which can be formed into various sizes and shapes of kitchen countertops. For those seeking something a bit different, the natural look of quartz may work well in your kitchen. Colors may be varied, but white, beige, and clear are the most common.
