Among the oldest known stone on earth, granite conjures up images dramatic mountain ranges - as well as stylish kitchen countertops. Formed from solidified molten rock at great depths and under great pressure far below the continents, this hard, dense and resilient stone is also one of the most popular. The word granite is derived from the Latin word granum, meaning grain, in reference to the stone's granular appearance. Primarily composed of quartz, feldspar, potassium and mica, this coarse-grained igneous rock is usually available in darker colors, but also pinks and light grays. Used as a building material since ancient times, granite now adds drama to the world's most modern homes and commercial buildings.
