Granite is a natural igneous stone that is quarried from the earth. True granite contains 20-60% quartz so it is not quite as durable as quartz. Granite comes in hundreds of different colors and usually have a “spattered” or “swirled” grain and can contain many colors within one block, slab, or countertop. It naturally contains fissures that are marginal variations in the composition of the natural stone. Fissures are not cracks and do not structurally impair the function or durability of granite. Instead, they add to the aesthetic appearance and uniqueness of each finished piece.
