Marble: Marble offers a beautiful countertop option, with its stunning variations and polished surface. It's expensive — often the most expensive option — with a typical $125- to $250-per-square-foot price tag. An emerging option in marble is a honed version, which takes the sleek look of the usually shiny stone and gives it a duller, unfinished feel. Owings says the countertops are typically filed to a minimal 3/4-inch thickness, but as always with marble, maintenance can be a deterrent. Even when polished and sealed, marble can be scratched and stained by foods and liquids.
