The countertop is Cambria Sussex. My selection sheet says that the backsplash is 'Jura Grey' honed 3x6 limestone from Waterworks - this tile was special order. All of the tile in this kitchen came from Waterworks, so if you are thinking of going with the same look, it may be a good thing to speak to one of their reps and maybe even send them this photo while you are planning.

Thank you very much!
