Princess Cut Diamond

       The Princess cut is the square version of the brilliant round cut usually comprised of either 57 or 76 facets with a typical ratio of 1.0 to 1.05.
Its pyramidal shape with four bevelled sides creates more light dispersion than any other square shaped diamond, making it popular for both solitaire engagement rings and earrings.
As it is a patented cut, it may be referred to as a Square Modified Brilliant on a laboratory certificate (eg. GIA or AGS), or a Rectangular Modified Brilliant if it has a ratio greater than 1.05.
The name “Princess Cut” was originally used in connection with another diamond cut known as the “Profile” cut, which was designed by London cutter Arpad Nagy in 1961. The same name was later used and made popular by Ygal Perlman, Betzalel Ambar, and Israel Itzkowitz in Israel, who in 1979 created the Princess cut (or Square Modified Brilliant) as it is known today.
When purchasing a princess diamond ring, it may be helpful to remember that you should avoid diamonds with a higher table percentage than depth percentage. The table is the uppermost surface of the diamond that runs flat across the top, parallel to the girdle. The depth, on the other hand, is the distance between the lowest and highest part of the diamond. A princess diamond ring can have more of a square or rectangular shape, and the style that you choose depends entirely on your preference.
However, the more rectangular that a princess diamond ring is, the lower the price in most situations. Once you’ve determined the exact cut, clarity and color you’d like, it’s time to pick a setting that will make your diamond sparkle and shine!
