Engineered stone, often referred to as quartz in the context of countertops, is a man-made product crafted by combining natural quartz particles with a small percentage of polymer resin. This blend results in a hard, non-porous surface. While natural stone, like granite or marble, is extracted directly from the earth and polished for use, engineered stone is fabricated using both natural and synthetic components to achieve a combination of durability and aesthetic variety.
