NVS Remodeling & Design Hi, the tile is 4x4 Pearl Tumbled Travertine. I do not have the name of the inserts, but I do know that the tile for this project was purchased by the client at Mosaic Tile Company. They have beautiful showrooms in Northern Virginia, with their new flagship showroom in Chantilly being especially impressive. Here is their website for more information - http://www.mosaictileco.com/ Best of luck with your projects!
