The Unfilled/Unpolished Travertine is the most popular italian travertine. It shows a light beige background color. Its texture typically presents swirled veins coming in shades of brown and grey. It shows frequently small dark areas due to natural iron inclusions. The stripes /veins can extend from end to end of the table or blend throughout giving the appearance of ocean waves. In its natural form has “holes”, “pores” and “fissures” that are not filled or sealed. Consequently the surface is not regular due to the presence of holes and pores that determine the natural characteristic of travertine itself.
