Abstract
A wall block comprises an upper surface spaced apart from a substantially parallel lower surface, opposed first and second faces, and opposed side surfaces converging between respective ends of the first and second faces. Blocks in a wall may be stacked on top of each other in either a vertical, set forward or set backward relationship. A three-block system for constructing walls includes a small, medium, and large block, each having two differently sized faces that can serve as the exposed face on one side of a wall. The small, medium, and large blocks can be manufactured using a single mold that is configured to provide a roughened texture resembling natural stone on two opposing faces of each block.
