Artificial stone and method of preparing the same

1. An artificial stone, comprising:

a solid material; and

surface-treated stone elements in the solid material, wherein:

the surface-treated stone elements are transparent stone elements having a coloring material disposed on surfaces thereof, the coloring material includes a metal,

transparent portions of the surface-treated stone elements are exposed at a surface of the artificial stone, and

the transparent stone elements are entirely or partially covered by the coloring material.

2. The artificial stone as claimed in claim 1 , wherein the artificial stone includes a first plurality of the surface-treated stone elements, each having a first portion within the artificial stone and a second portion exposed at a surface of the artificial stone, wherein:

the coloring material is disposed on surfaces of the first portions of the first plurality of the surface-treated stone elements, and

the coloring material is not disposed on surfaces of the second portions of the first plurality of surface-treated stone elements.

3. The artificial stone as claimed in claim 2 , wherein the artificial stone further includes a second plurality of surface-treated stone elements that are entirely within the artificial stone, the second plurality of surface-treated stone elements being entirely covered by the coloring material.

4. The artificial stone as claimed in claim 1 , wherein the metal includes one or more of gold, silver, copper, aluminum, or nickel.

5. The artificial stone as claimed in claim 1 , wherein the transparent stone elements include an organic polymer.

6. A method of preparing an artificial stone, comprising:

combining a first material and surface-treated stone elements;

forming the combined first material and surface-treated stone elements into a solid material that has a shape having an exposed surface; and

processing the exposed surface so as to expose transparent portions of the surface-treated stone elements at a surface of the artificial stone, wherein the surface-treated stone elements are transparent stone elements having a coloring material disposed to entirely cover or partially cover surfaces of the transparent stone elements, and the coloring material including a metal.

7. The method as claimed in claim 6 , further comprising, prior to the combining, applying the coloring material to the surfaces of the transparent stone elements to prepare the surface-treated stone elements.

8. The method as claimed in claim 7 , wherein preparing the surface-treated stone elements includes pulverizing a transparent solid to form chips, and then applying the coloring material to surfaces of the chips.

9. The method as claimed in claim 8 , wherein the transparent solid includes one or more of an acrylic resin or a polyester resin.

10. The method as claimed in claim 7 , wherein preparing the surface-treated stone elements includes applying the metal to a surface of a transparent solid, and then pulverizing the transparent solid.

11. The method as claimed in claim 10 , wherein the transparent solid includes an organic polymer that includes one or more of an acrylic resin or a polyester resin.

12. The method as claimed in claim 6 , wherein the first material includes a polymeric resin and an inorganic filler.

13. The method as claimed in claim 12 , wherein the polymeric resin includes an acrylic resin.

14. The method as claimed in claim 6 , further comprising combining another type of stone elements with the surface treated stone elements and the first material, wherein the other type of stone elements do not have the coloring material disposed on surfaces thereof.

15. The method as claimed in claim 6 , wherein processing the exposed surface so as to expose transparent portions of the surface-treated stone elements includes removing the coloring material from surfaces of surface-treated stone elements that are at the exposed surface.

16. The method as claimed in claim 15 , wherein removing the coloring material includes removing a predetermined thickness of the exposed surface.

17. The method as claimed in claim 16 , wherein removing the predetermined thickness of the exposed surface includes abrading the exposed surface.

18. The method as claimed in claim 6 , wherein the coloring material includes the metal and a paint.

19. The method as claimed in claim 6 , wherein the metal includes one or more of gold, silver, copper, aluminum, or nickel.
