disclosure defines a jagged outline that is non repetitive when contouring the paving stone 10 the paving stone 10 has projections and depressions of different shapes and different sizes i e receiving cavities moreover the paving stone 10 has a generally elongated shape with one end along its longitudinal axis 12 being smaller than the opposite end resulting in a distinguishable orientation this elongated shape facilitates the positioning of the paving stones in an interlocked herringbone arrangement as well as in an interlocked linear arrangement or in a combination thereof as described hereinafter referring to fig2 there is illustrated a pre cast paving stone 20 having a body 21 which is the same as the paving stone 10 of fig1 and with an exposed surface portion 22 projecting upwardly from the body 21 the long face of the body 21 is the interface of the paving stone 20 with the ground or other surface upon which the paving stones will be laid out e g it is possible to lay out the paving stones on edges to form a stone face wall in an embodiment the exposed surface portion 22 is the visible portion of the paving stone 10 when laid out the paving stone 20 is a pre cast concrete stone and may have the exposed surface portion 22 formed with a plurality of smaller distinct substones 23 spaced apart to form joints therebetween to simulate a flagstone assembly the exposed face 23 u2032 of the substones 23 may have a textured surface to simulate real stones a shoulder 25 may be defined by the base 20 at the outer periphery of the exposed surface portion 22 to form joints with adjacent stones when.
