Travertine has quickly become one of the most popular natural stone flooring materials on the market today, lending warmth and balance to virtually any color combination. Commonly found in shades of brown, it is also available in variations of red, gold, off-white, and silver. Travertine contains unique movement and characteristic pores, created over centuries by sedimentation, which give it a slightly rustic apperance, but which can also be filled and smoothed for a more refined look. In addition, Travertine can be vein cut, which is a method of quarrying that allows the natural layering of the stone to be visible.
