Types of Travertine
Honed Travertine with a smooth, non-reflective surface achieved by grinding the surface.
Tumbled Travertine which has been processed so that it looks "aged" or "antiqued" with rounded corners and edges.

Both honed and tumbled travertine can be purchased as unfilled or filled.

Unfilled: Travertine with its natural holes and pits. See the first picture below. Some people purchase unfilled and then fill the holes and pits with grout for a different, blended look as in the second picture.

Filled: Travertine with its natural holes and pits filled with hardener and dust during the cutting and honing process.

Tumbled, unfilled travertine
