Travertine available in variety of colours ranges from ivory and beige to walnut and gold. The color is determined by the amount of iron or other organic impurities found in the stone. Travertine is typically polished to a smooth finish, honed into a matte finish, brushed/tumbled into a textured surface, filled to a smoother finish, or chiseled to an uneven finish. It  is a popular building stone for both interior and exterior applications.
