Check Out Mason Veneers!

Mason Veneers manufactured stone has been molded from natural stone to create an identical copy of the stone’s texture. This results in surface anomalies that add to the overall character of the stone, making Mason Veneers manufactured stone virtually indistinguishable from natural stone.
