Sareen Stone’s Charcoal Grey Granite cobblestones were selected by Sydney Brick Paving Company to pave the driveway to The King’s School in Sydney’s northwest. Charcoal Grey Granite Cobblestones are Sareen Stone’s best-selling cobblestone. Available in a stunning flamed finish, they can be supplied on mesh, for ease of handling during installation. Alternatively, loose cobblestones are available on special order, which a minimum of 8 weeks lead time is required.
