Granite has become one of the most coveted countertop materials because of its versatility, durability, and beautiful appearance. It tends to have a grainy appearance that also contains structures of interlocking crystals that gives it a unique appearance.
The presence of many different mineral types including mica, quartz, feldspar, and others within a given slab of granite gives it unique patterning and other qualities.
The reason granite is such a great material for kitchen countertops is because it can withstand incredibly high heats (over 1,200 degrees Fahrenheit) while also being nearly immune to scratches, dents, chips, and other impacts that might affect other surface types. You would need to use a sledgehammer or something more powerful to damage a granite countertop.
