Granite is an intrusive (within the Earth's crust) igneous rock; the formation occurs by magma flowing into pockets deep beneath the Earth's surface. Over millions of years it cools and crystallizes. Granite is found all over the world. The more colorful and exotic granite slabs are found in Africa, Brazil, China, Italy, and India. Other exporters of granite are Argentina, Egypt, Finland, Iran, Norway, Sardinia, Spain, and the Ukraine. Granite is found in abundance in the United States but the colors are more compatible with monument and exterior works.
