"Gerrity has good relationships with their clients. That's why they're the best," declares one professional. Unlike other suppliers, which merely show you a sample of the stone you can purchase, Gerrity has a huge warehouse filled with actual slabs (a critical factor, since no two pieces of granite or marble are alike). After choosing the stone you want—and working with Gerrity to lay out the pieces—you're all but guaranteed precisely the look you're after. For a truly one-of-a-kind countertop, Gerrity carries a collection of rare stones from around the world.
