Marble has been used for centuries to beautify homes and palaces and its timeless beauty continues to create stunning pieces in today's modern homes. Under heat and pressure, limestone is transformed into marble over about 540 million years. Marble is made up of mostly calcite- a mineral form of calcium carbonate with some mica inclusions. Found in the mountain regions of Canada, Italy, Germany, Spain, United States, and other countries worldwide, Marble adds sophistication and elegance to any space. This metamorphic stone is most commonly used for vanity tops, floors, foyers, fireplace facings, hearths, tub decks, shower walls, and windowsills.
