Princess cut invisible stone setting

Abstract

A new and improved stone setting is disclosed that supports the stone with an invisible setting comprising a notch on a facet of the stone with a portion of an upwardly extending support bracket extending into the notch and forming an interference fit therewith. The notch is generally V-shaped with an upper surface and a lower surface. The stone setting does not require support from a sidewall or a prong.

What is claimed is:  
     
         1 . A new and improved notched, invisible precious and semi-precious stone setting that does not require the use of a four sided setting socket in a plane parallel with a table comprising: 
 a stone having a table, at least one outwardly downwardly extending facet, a girdle, and at least two inwardly downwardly extending facets such that a width of the girdle is greater than a width of the table;    a notch extending at least partially along two opposed inwardly downwardly extending facets, the notch having an upper surface and a lower surface, the upper surface generally extending in a parallel plane with the table; and,    at least two upwardly extending support brackets having an upper surface and a lower surface with no perpendicular cross-support bracket along a plane of the upper surface of the at least two support brackets, a perpendicular cross-support bracket connected to the at least two parallel upwardly extending support brackets about the lower surface of the at least two support brackets wherein a portion of the upper surface of each support bracket being at least partially deformed into the notch to secure the stone whereby an invisible setting is formed.    
     
     
         2 . The setting of  claim 1  wherein the table is quadrangular with four inwardly downwardly extending facets meeting at an apex.  
     
     
         3 . The setting of  claim 1  wherein the notch is a V-shape.  
     
     
         4 . The setting of  claim 3  wherein the lower surface of the notch extends at an angle of about 10 to 25 degrees from the upper surface of the notch.  
     
     
         5 . The setting of  claim 1  further comprising additional upwardly extending support brackets having an upper surface and a lower surface whereby a plurality of stones may be set.  
     
     
         6 . The setting of  claim 1  further comprising at least one prong.  
     
     
         7 . The setting of  claim 1  further comprising at least one sidewall.  
     
     
         8 . The setting of  claim 1  wherein at least one of the upward extending support brackets further comprises a projection that is inserted into the notch.  
     
     
         9 . The setting of  claim 1  wherein at least one of the upper surfaces of the support bracket forms an interference fit with the stone.  
     
     
         10 . A new and improved stone setting that does not require a setting socket comprising: 
 a stone having a V-notch extending at least partially into the stone and a girdle, the notch having an upper surface and a lower surface, the lower surface extending at an angle of about 10 to 25 degrees from the upper surface with a portion of an upwardly extending support bracket deformed thereto to secure the stone with an opposing upwardly extending support bracket, the support brackets supported from beneath the stone by a cross-support.    
     
     
         11 . The stone setting of  claim 10  wherein the upper surface of the notch is generally planar with the girdle.  
     
     
         12 . The stone setting of  claim 10  further comprising a side surface connected to a portion of at least one of the support brackets.  
     
     
         13 . The stone setting of  claim 10  further comprising a side surface connected to a portion of the cross-support.  
     
     
         14 . The stone setting of  claim 12  further comprising a design in the side surface.  
     
     
         15 . The stone setting of  claim 10  wherein the portion of the upwardly extending support bracket forms an interference fit with the notch.  
     
     
         16 . A new and improved pendant earring invisible stone setting comprising: 
 at least two stones, having a girdle, a table, and a facet, with a V-notch on opposing surfaces having an upper and a lower surface;    the upper surface of the notches on opposing surfaces generally parallel with the table of the stones;    at least two opposing support brackets having projection portions that are deformed within the notch; and,    a cross-support member below the stones.    
     
     
         17 . The earring of  claim 16  wherein the table of the stones is generally parallel with a surface of the projection portions.  
     
     
         18 . The earring of  claim 16  further comprising an earring stud adapted for releasable engagement with an earring backing.  
     
     
         19 . The earring of  claim 16  wherein the stones are releasably secured within the earring whereby a user may selectively change the stones on the earring.  
     
     
         20 . The earring of  claim 16  wherein the projection portions forms an interference fit with the notch.  
     
     
         21 . A new and improved stone setting comprising: 
 a stone having a side and a table;    at least two notches that extend at least partially along the table; and,    at least two parallel upwardly extending support brackets having an upper surface and a lower surface wherein a portion of the upper surface of each support bracket being at least partially inserted into the notch to form an interference fit whereby the stone is secured in the setting.
