Used for centuries in the finest homes and villages in Europe, the classic appeal of this stone makes porphyry a very coveted material for cobblestones. It is known for its purplish, warm earthy tone that enhances the environment. Harder than marble or granite, porphyry resists wear, discoloration and staining, which makes it ideal for driveways and walkways. Its natural surface resists slipping and is less likely to crack, chip or crumble in freezing weather. Porphyry has extremely low maintenance costs, as proved by the excellent conditions of the many roads and squares paved hundreds of years ago through out the world.
