Claims

exact text as granted — not AI-modified
1 . A princess cut diamond comprising:
 a diamond in the shape of a square or a rectangle having four sides and four corners;   each of said four corners being rounded corners wherein said corners do not have any points;   said rounded corners being of a size that when placed in a setting said corners are covered by said setting;   said diamond having a crown and a pavilion with four beveled sides.   
     
     
         2 . The diamond of  claim 1 , wherein said princess cut diamond is within said setting, said a user cannot tell if said corners are rounded or pointed because setting covers said corners. 
     
     
         3 . The diamond of  claim 1 , wherein said rounded corners of said princess cut diamond do not have a propensity to break or fracture during or after setting. 
     
     
         4 . The diamond of  claim 1 , wherein there is more surface area available for setting at said rounded corners of said princess cut diamond than at pointed corners of a conventional princess cut diamond. 
     
     
         5 . The diamond of  claim 1 , wherein said rounded corners of said princess cut diamond are fully covered and securely set using prongs. 
     
     
         6 . The diamond of  claim 1 , wherein dimensions of face-up surface of said princess cut diamond are equal to dimensions of face-up surface of a princess cut diamond with pointed corners once said princess cut diamond and said princess cut diamond having pointed corners are mounted in a similar setting. 
     
     
         7 . The diamond of  claim 1  wherein said four corners of said princess cut diamond are rounded and symmetrical, creating a homogeneous and uniform shape.
