Upgrade your hardscape with Gray Granite Cobblestone Pavers in regulation size, featuring a precision cut design and natural rockface surface. These larger flamed granite cobblestones (9 in. x 4.5 in. x 4.5 in.) provide a bold, classic cobble appearance while offering more consistent sizing on the sides and base for tighter joints and a more uniform installation compared to traditional tumbled cobblestones.Each cobblestone is flame-treated using high heat to create a textured, slip-resistant surface while maintaining the natural durability and strength of granite. The regulation size cobble is commonly used in driveways, roadways, walkways, patios, and edging where a larger, more traditional cobblestone look is desired.The combination of sawn sides and a rugged natural top delivers the perfect balance of old-world cobblestone character and modern installation performance. Granite is one of the most durable natural stones available and is rated for both foot traffic and vehicular use. As a natural stone product, variations in color, size, and texture will occur, enhancing the unique appearance of each piece.
