A sedimentary rock formed by the
accumulation of organic remains such as shells and
coral, limestone consists mainly of calcium carbonate.
Look no further than the Cliffs of Normandy and
the Rock of Gibraltar to see its grandeur. In the
home, limestone turns floors, walls, and counters
into natural works of art. It's been used as a traditional
building material in Europe for centuries because
of its inherent beauty.
