Granite is an Intrusive, Felsic, Igneous rock. This means it is primarily of volcanic origin, formed through millions of years of extreme heat and pressure from the crystallization of cooled magma.
A wide array of colorations is possible, depending on the chemistry and mineralogy the granite was formed by. Because of its exceptional strength, it is widely used for exterior applications, such as columns, statuary, balustrades, cladding, paving and curbing.
