Claim:
A set of concrete blocks comprising: (a) a first concrete block including (i) at least 6 sides including a first generally vertical exposure face, an opposite second face, opposite planar top and bottom faces extending between the first exposure face and second face, and opposite first and second side faces extending between the first exposure face and second face and the top and bottom faces; (ii) the first exposure face having a non-planar first topographical definition that is irregular both along the length and across the height of the first exposure face and a first edge along the first side face and a second edge along the second side face; (A) the first edge having a first irregular profile; and (b) a second concrete block including (i) at least 6 sides including a first generally vertical exposure face, an opposite second face, opposite planar top and bottom faces extending between the first exposure face and second face, and opposite first and second side faces extending between the first exposure face and second face and the top and bottom faces; (ii) the first exposure face of the second concrete block having a non-planar second topographical definition that is irregular both along the length and across the height of the first exposure face and a first edge along the first side face and a second edge along the second side face; (A) the second topographical definition being different from the first topographical definition; (B) the second edge of the second concrete block having an irregular profile that is the mirror image of said first irregular profile so that when the second edge of the second concrete block is placed adjacent the first edge of the first concrete block and the edge profiles are aligned, there is a seamless appearance along the respective first exposure faces.
