A princess cut diamond having no points, but instead having rounded corners, so that the diamond is more stable, and has a less propensity to have any breakage.
Claims

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.
