Princess Cut Rings

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. Other precursors of the Princess cut include the Barion – a square cut with rounded corners created in 1971 by South African cutter Basil Watermeyer, and the Quadrillion – a similar cut with only 49 facets, also created by Perlman, Ambar and Itzkowitz and initially distributed by Ambar Diamonds in Los Angeles. Following several years of optical research, the modern Princess cut was created – a square stone of 58 facets arranged similarly to those of a round brilliant 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. 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.
