A: Granite countertops are 100% natural stone mined from the earth, while quartz countertops consist of 93-95% crushed natural quartz mixed with a small amount of other minerals and colorants, making quartz a man-made material. When it comes to design, granite is always unique with patterns ranging from simple to intricate while quartz is man-made and has formulated patterns, which change as the industry develops.
