Abstract

A multi-stone gemstone or diamond arrangement and a prong setting for receiving four substantially triangular-shaped gemstones or diamonds in the setting for forming a substantially rectangularly-shaped gemstone or diamond arrangement. A prong setting including a prong assembly having four prong members. The prong setting also includes an upper rail assembly having four side rail members and four corner rail members; the four corner rail members being attached to the four prong members, respectively. The prong setting further includes an upper frame assembly having first and second crossbar members, the first crossbar member having first outer ends and the second crossbar member having second outer ends. The first and second crossbar members form an X shaped configuration and each is connected at its respective first and second outer ends thereof to the corner rail members for forming four seating areas. Each of the four seating areas is for receiving therein one of four triangular-shaped gemstones or diamonds within each of the four seating areas. The four triangular-shaped gemstones or diamonds each have three side walls and each have first and second retaining corners and a third apex corner, respectively; each of the first and second retaining corners form a corner retaining angle with at least two of the side walls. Each of the four prong members have a retaining insert slot therein for receiving and engaging at least a portion of the first and second retaining corners of two adjacent gemstones or diamonds to keep the four gemstones or diamonds seated within each of the four seating areas of the prong setting.

Claims

exact text as granted — not AI-modified
1 . A multi-gemstone or diamond arrangement and a prong setting for receiving four substantially triangular-shaped gemstones or diamonds in the setting for forming a substantially rectangular-shaped gemstone or diamond arrangement; comprising: 
 a) a prong setting including a prong assembly having four prong members;    b) an upper rail assembly having four side rail members and four corner rail members; said four corner rail members being attached to said four prong members, respectively;    c) an upper frame assembly having first and second crossbar members, said first crossbar member having first outer ends and said second crossbar member having second outer ends;    d) said first and second crossbar members forming an X shaped configuration and each being connected at their respective first and second outer ends thereof to said corner rail members for forming four seating areas;    e) each of said four seating areas for receiving therein one of said four triangular-shaped gemstones or diamonds within each of said four seating areas;    f) said four-triangular shaped gemstones or diamonds each having three side walls and each having first and second retaining corners and a third apex corner, respectively; each of said first and second retaining corners forming a corner retaining angle with at least two of said side walls;    g) each of said four prong members each having a retaining insert slot formed therein for receiving and engaging at least a portion of said first and second retaining corners of two adjacent gemstones or diamonds to keep said four gemstones or diamonds seated within each of said four seating areas of said prong setting.    
   
   
       2 . A multi-stone arrangement and setting in accordance with  claim 1 , wherein each of said four prong members includes an upper prong end, a lower prong end, an exterior wall surface and an interior wall surface having a center section area.  
   
   
       3 . A multi-stone arrangement and setting in accordance with  claim 2 , wherein each of said four corner rail members is attached to said interior wall surface at said center section area of each of said four prong members, respectively.  
   
   
       4 . A multi-stone arrangement and setting in accordance with  claim 2 , wherein each of said retaining insert slots is positioned at said upper prong end on said interior wall surface of each of said four prong members.  
   
   
       5 . A multi-stone arrangement and setting in accordance with  claim 1 , wherein said prong setting further includes a lower frame assembly having four lower frame side rail members for providing additional structural strength to said prong setting.  
   
   
       6 . A multi-stone arrangement and setting in accordance with  claim 2 , wherein each of said lower frame side rail members is attached to said lower prong end of each of said four prong members, respectively.  
   
   
       7 . A multi-stone arrangement and setting in accordance with  claim 1 , wherein said third apex corner of two of said triangular-shaped gemstones or diamonds includes an acute arc angle alpha (α) of less than 90°.  
   
   
       8 . A multi-stone arrangement and setting in accordance with  claim 7 , wherein said acute arc angle alpha (α) includes the acute arc angle alpha (α) in the range of 60° to 75° with a preferred acute arc angle alpha (α) of 70°.  
   
   
       9 . A multi-stone arrangement and setting in accordance with  claim 1 , wherein said third apex corner of the other two of said triangular-shaped gemstones or diamonds include an obtuse arc angle beta (β) of greater than 90°.  
   
   
       10 . A multi-stone arrangement and setting in accordance with  claim 9 , wherein said obtuse arc angle beta (β) includes the obtuse arc angle beta (β) in the range of 105° to 115° with a preferred obtuse arc angle beta (β) of 110°.  
   
   
       11 . A multi-stone arrangement and setting in accordance with  claim 1 , wherein one of said three side walls of said triangular-shaped gemstone or diamond is an outer side wall being adjacent and parallel with one of said four side rail members.  
   
   
       12 . A multi-stone arrangement and setting in accordance with  claim 11 , wherein said corner retaining angle of said first and second retaining corners of two of said triangular-shaped gemstones or diamonds includes a corner retaining angle gamma (γ) relative to said outer side wall.  
   
   
       13 . A multi-stone arrangement and setting in accordance with  claim 12 , wherein said corner retaining angle gamma (γ) is 35° relative to said outer side wall of said two of the triangular-shaped gemstones or diamonds.  
   
   
       14 . A multi-stone arrangement and setting in accordance with  claim 11 , wherein said corner retaining angle of said first and second retaining corners of the other two of said triangular-shaped gemstones or diamonds includes a corner retaining angle delta (δ) relative to said outer side wall.  
   
   
       15 . A multi-stone arrangement and setting in accordance with  claim 14 , wherein said corner retaining angle delta (δ) is 55° relative to said outer side wall of said other two of the triangular-shaped gemstones.  
   
   
       16 . A multi-stone arrangement and setting in accordance with  claim 15 , wherein said corner retaining members of two adjacent triangular-shaped gemstones or diamonds have said corner retaining angles gamma (γ) and delta (δ) being in alignment with each other to cooperate in forming a straight edged corner member being received within each of said retaining insert slots of said four prong members.
