Improved illusion plate for setting diamonds

Abstract

This invention relates to enhancing the visual effect of diamonds held in an illusion plate. The improved illusion plate provides enhanced diamond reflectivity by changing the shape and angle of the facet cuts in the annular ring forming the illusion plate, providing greater depth, which creates enhanced reflectivity of the combination of the diamond in the illusion plate such that the diamond appears to be larger than its actual size.

1 . An illusion plate to enhance the appearance of a stone set therein, said illusion plate comprising:
 an annular structure having an opening in the center to hold said stone,   an annular ring surrounding said opening comprising repeating facets having facet cuts therein, and   said facet cuts forming a domed shape structure.   
     
     
         2 . An illusion plate according to  claim 1 , wherein said domed shape structure comprises a substantially convex shape. 
     
     
         3 . An illusion plate according to  claim 1 , wherein said facet cuts have angular cuts, wherein said angular cuts are approximately at least 40° angles. 
     
     
         4 . An illusion plate according to  claim 3 , wherein the angle of said annular cuts is at least 45°. 
     
     
         5 . An illusion plate according to  claim 3 , wherein the angles of said facet cuts are uniform in said annular ring. 
     
     
         6 . An illusion plate according to  claim 1 , wherein the height of said illusion plate is at least 1.2 mm. 
     
     
         7 . An illusion plate according to  claim 1 , wherein said stone is a diamond. 
     
     
         8 . An illusion plate according to  claim 7 , wherein said diamond has bezel and star cuts and the facets of said annular ring of said illusion plate continues the faceted appearance of said bezel and star cuts. 
     
     
         9 . An illusion plate according to  claim 1 , further comprising a halo surrounding said illusion plate. 
     
     
         10 . An illusion plate according to  claim 9 , wherein said halo comprises a plurality of stones surrounding said illusion plate. 
     
     
         11 . An illusion plate according to  claim 1 , wherein said illusion plate has a depth of at least 4 mm.
