Gemstone Setting Arrangement and Method for Setting a Gemstone

Abstract

Disclosed is a gemstone setting arrangement in which a gemstone includes a groove disposed proximal a culet of the gemstone. The gemstone setting arrangement further includes a setting having a culet seating portion and a girdle retaining portion. A setting abutting portion of the groove engages a gemstone abutting portion of the culet seating portion. Translation and rotation of the gemstone relative to the setting are inhibited. Also disclosed is a method for setting a gemstone.

1 . A gemstone setting arrangement comprising:

       2 . A gemstone setting arrangement according to  claim 1 , said pavilion portion having a boundary that generally decreases in the direction of the culet.  
   
   
       3 . A gemstone setting arrangement according to  claim 1 , said setting abutting portion comprising a wall having a generally planar wall surface, said obverse face of said gemstone being generally planar and generally defining a table plane, said wall surface of said setting abutting portion generally defining a plane that is approximately normal with respect to said table plane.  
   
   
       4 . A gemstone setting arrangement according to  claim 1 , said groove having a terminal obverse point, said terminal obverse point being disposed at a distance along said pavilion portion that is greater than 75% of the distance between said girdle portion and said culet.  
   
   
       5 . A gemstone setting arrangement according to  claim 1 , said groove having a terminal obverse point, said terminal obverse point being disposed at a distance along said pavilion portion that is greater than 85% of the distance between said girdle portion and said culet.  
   
   
       6 . A gemstone setting arrangement according to  claim 1 , said girdle retaining portion comprising first and second channel retaining portions.  
   
   
       7 . A gemstone setting arrangement according to  claim 1 , said gemstone comprising a diamond.  
   
   
       8 . A gemstone setting arrangement according to  claim 1 , said gemstone comprising a diamond including at least fifty-eight facets.  
   
   
       9 . (canceled)  
   
   
       10 . A gemstone setting arrangement according to  claim 1 , said setting comprising gold.  
   
   
       11 . A gemstone setting arrangement according to  claim 1 , said setting comprising silver.  
   
   
       12 . A gemstone setting arrangement according to  claim 1 , said setting comprising platinum.  
   
   
       13 . A gemstone setting arrangement according to  claim 1 , said setting comprising palladium.  
   
   
       14 . A gemstone setting arrangement according to  claim 1 , said setting comprising titanium.  
   
   
       15 . A method for setting a gemstone, comprising: 
 providing a gemstone, said gemstone having an obverse face, a girdle portion, a culet and a pavilion portion, said gemstone including a groove in said pavilion portion, said groove being proximal said culet relative to said girdle portion and having a setting abutting portion;    providing a setting having a girdle retaining portion and a culet seating portion;    positioning said gemstone relative to said setting such that said setting abutting portion engages a gemstone abutting portion of said culet seating portion; and    causing said girdle retaining portion to engage said gemstone proximal said girdle portion to thereby inhibit said gemstone from moving with respect to said setting.    
   
   
       16 . A method according to  claim 15 , further comprising: 
 providing a gemstone that does include said groove; and    cutting said groove into said gemstone.    
   
   
       17 . A gemstone setting arrangement comprising: 
 a gemstone having an obverse face, a girdle portion, a culet, and a pavilion portion;    a setting having a girdle retaining portion and a culet seating portion, the girdle retaining portion engaging said gemstone proximally said girdle portion relative to said culet, said culet of said gemstone being seated in said culet seating portion;    said culet seating portion comprising a gemstone abutting surface, said gemstone including a groove in said pavilion portion, said groove being proximal said culet relative to said girdle portion, said groove having a setting abutting portion, said setting abutting portion engaging said gemstone abutting surface of said culet seating portion, whereby said gemstone is inhibited from moving with respect to said setting.    
   
   
       18 . A gemstone setting arrangement according to  claim 17 , said girdle retaining portion opposing said gemstone abutting surface.  
   
   
       19 . A gemstone setting arrangement according to  claim 17 , said setting abutting portion comprising a wall having a generally planar wall surface, said obverse face of said gemstone being generally planar and generally defining a table plane, said wall surface of said setting abutting portion generally defining a plane that is approximately normal with respect to said table plane.  
   
   
       20 . A gemstone setting arrangement according to  claim 1 , further comprising at least a second gemstone.  
   
   
       21 . A gemstone setting arrangement according to  claim 1 , said girdle retaining portion having a first portion relatively proximal to said culet seating portion and a second portion relatively distal to said culet seating portion, said second portion presenting a setting portion obverse face, said setting portion obverse face being disposed at a distance from said culet seating portion that is less than the distance of said gemstone obverse face from said culet seating portion towards a direction normal to said gemstone obverse face.  
   
   
       22 . A gemstone setting arrangement according to  claim 1 , wherein said gemstone includes only a single groove proximal said culet portion.  
   
   
       23 . A gemstone setting arrangement comprising: 
 a gemstone having a girdle, a culet, and a pavilion portion between said girdle and said culet; and    a setting having a girdle retaining portion and a culet seating portion, said girdle retaining portion engaging said gemstone proximal said culet;    said gemstone including a groove in said pavilion portion, said groove being proximal said culet relative to said girdle, said gemstone engaging said culet seating portion at said groove,    whereby said gemstone is inhibited from moving with respect to said setting.
