The travertine itself is great. However, the sample I received was clearly not from the same lot as what was for sale. I received a sample (4x4 size even though product in question is 6x6) that was a golden/honey/amber color. It looked like the color my clients had requested, so I placed the order. When I received it, I immediately noticed that the color was much different than the sample. The travertine I received was a yellow/sunny/dandelion color and lighter in tone than the sample. I would upload pictures but they don't offer that option.
I realize natural stone comes with an acceptable level of variation, but it was so different that the "new" color was not compatible with the room. I had to go with a different color stone altogether.
