Marble has both scientific and commercial definitions. Scientific marble was once limestone that achieved metamorphosis from intense pressures and high temperatures within the earth. This trauma altered its crystalline structure, introducing other minerals that produced the valuable colors and veining seen in the stone. Commercially, any stone capable of taking a polish (with the exception of granite) is known as marble. This includes travertine, onyx, serpentine, and limestone.
