Abstract: A stone arrangement for a corner is provided which includes two stones for positioning at the corner, wherein one of the stones is provided with a curved corner and the second stone is provided with a sharp corner and wherein the stones have matching contours at a location where they abut so that the stones have improved aesthetic appearance. Further, the stones are formed to provide consistent dimensions when arranged at a corner so that stones extending further from the corner maintain intended dimensional tolerances.

Abstract: A lightweight artificial stone system comprises a plurality of artificial stones, each of the artificial stones formed of at least some portion of cement, expanded glass, the lightweight artificial stones having a density in the range of between about 30 and 70 pounds per cubic foot.

Abstract: A method of forming a lightweight artificial stone comprises sizing an existing rock to a first set of dimensions and compensating for shrinkage of moldable cement and expanded glass mixture, squaring the existing rock at least once, laying out at least one of the existing rock, forming a mold of the existing rock, removing the existing rock from the mold, filling the mold with the moldable cement and expanded glass mixture, forming at least one dimensionally accurate stone.

Abstract: A lightweight artificial stone system comprises a plurality of artificial stones, each of the artificial stones formed of at least some portion of cement, expanded glass, and styrene, the lightweight artificial stones having a density in the range of between about 30 and 70 pounds per cubic foot, each of the stones having six sides and including a first height dimension and a second width dimension, each of the height and width dimensions having a length unit being substantially a multiple of two, each of the stones having four ninety degrees corners and four of the six sides having a smooth surface to provide tight, cement-free seams between adjacent stones, the tight, cement-free seams inhibiting viewing of structure behind said plurality of artificial stones, each of the stones being of such a light weight so as to be held in position in the system by a lath-less and cement-free adhesive.
