Outdoor Granite Cobblestone is a small, naturally rounded rock not the quarried granite stones commonly referred to as cobblestone. The rectangular quarried stone generally used for paving roads is called a sette, more commonly, Belgian blocks. With our reclaimed jumbo cobbles, customers have created gorgeous driveways, loose walkways, and one of a kind edging for plant beds. The color of an Outdoor Granite Cobblestone combines its original color and the patina it has acquired over generations on the road. When the patina is stripped off or the stones are broken open to show their natural color, stones that originally seem to be relatively similar in color are frequently quite different.
