Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments. Polished granite is also a popular choice for kitchen countertops due to its high durability and aesthetic qualities. It comes in many natural colors depending on their chemistry and mineralogy.

Physically, commercial granites are Hard, Compact rocks with fine to coarse grains of metamorphic or igneous origin.
