Pittsburgh Bluestone Cobblestones are the rarest and most exclusive of our reclaimed stone collection. We've never seen the beautiful Pennsylvania bluestone used as paving cobbles anywhere except in the city of Pittsburgh. Indeed, this particular type of sandstone, noted for its blue-grey coloration and decorative veining, is found only in the northern Pennsylvania area. Our reclaimed cobbles feature worn smooth tops for a true antique look.
