Abstract: The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.

Abstract: An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of generally congruent irregularly-shaped first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle ? of approximately 120°; a second pair of generally congruent irregularly shaped third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle ? of approximately 120°; a third pair of generally congruent irregularly shaped fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ? of approximately 120°; wherein the sides of each of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational image

Abstract: A covering unit for use in combination with similar units for covering a surface with a natural random look, the unit having an hexagonal body comprising first, second and third pairs of opposed and parallel sides. Each side has a central point of angular symmetry. The second and third pairs are similar to each other while the first pair is different from the others. The sides of the second and third pairs are provided with at least one split deviation along their length arranged so that each side of the second pair is a rotational image of the sides of the third pair, whereby in use in combination with other covering units: each side is matingly engageable with the sides of an equivalent pair of a neighbouring unit; and the unit has a central point of angular symmetry and is matingly engageable with a plurality of neighbouring unit.
