Limestone is a sedimentary rock, the result of millions of years of seashells, coal and a variety of organic matter settling and being compacted on the ocean floor. Patara Stone Limestone comes in a range of colors, and because it is a softer stone, is usually offered in a honed, matte finish as opposed to being highly polished. The natural hues of the sand and sea of our exquisite limestone will complete any line of flooring.
