Quartz countertops are a man-made product engineered to be ultra-durable and long-lasting. Quartz can be made to resemble a variety of natural stone types, including marble and granite. It can take on a number of colors and patterns. Granite and marble are natural stones. Granite is long-lasting, durable, scratch-resistant, and stain-resistant when properly sealed. Granite comes in a variety of colors including white, black, and brown. Marble is softer than granite and scratches more easily. If properly maintained and regularly sealed, marble can be stain-resistant and long-lasting. Marble comes in many colors but is most commonly available in gray and white. Many people are unable to tell the difference between marble, granite, and quartz-based on looks alone. Long-term performance and maintenance are the biggest differences between these three materials.
