What are the different finishes? What are the differences between?

Finishing stone is similar to sanding process: smaller grit and longer sanding gives stone more shinny polished look, whereas less will make it look more natural. Finish is a design preference. Usually polished surfaces are used where a modern look is sought. They require more delicate care and handling compared to antiqued or tumbled surfaces which have a natural patina and will take a better wear and tear over time.

Some stones like travertine have natural holes as a result of sedimentary minerals. These voids or holes can be left unfilled to give even more natural look to the floor. They are also available as filled travertine or you can grout the holes when you grout your joints.
