Marble is a metaphorical rock created by the recrystallization of limestone or dolomite. Marble is the most popular decorative stone that exudes elegance and quality. Throughout history, marble has been used in architectural design. The Pantheon in Rome, the Taj Mahal in India and the Acropolis in Greece were built of marble and that is the main reason why they still stand hundreds of years after they were built. Marble was once reserved for the homes of the wealthiest people, while today it is available to almost everyone.
