Travertine is available in a variety of colors and finishes. The most common travertine colors are Light, or cream, Beige, Gold, Walnut and Chocolate (Noce). Light is the lightest color with Chocolate being the darkest. Gold is a unique color with extreme variation within ranging from yellows to rust colors to an almost purplish brown color and everything in between.
The most common distinction in travertine comes from its finish. The most common finish for travertine is honed and filled. The honing process makes the surface of the tile flat and smooth but stops a few steps short of polishing the stone like a marble. Polished travertine is available but is not very common. Another common finish for the travertine brushed and chiseled. The brushing process gives the surface of the tile a little bit of texture while the chiseled edges give it an antiquated and worn look. Before buying travertine with a chiseled edge, check to see if the edges are machine or hand chiseled. The machine chiseled pieces are more uniform, but that uniformity can take away from the look you may be trying to achieve.
Travertine is also available in a tumbled finish which gives it an overall rounded appearance. Tumbled travertine is most often left unfilled and is used predominantly for kitchen backsplashes, bathrooms and in mosaics.
