The Princess cut is the second most popular piece form for diamonds, in addition to a brilliant round. The shape of a princess's face is square or rectangular and the profile or side shape is similar to an inverted pyramid with four sloping sides. The princess piece is a relatively new piece of diamond, created in the 1960s. It has gained popularity in recent years as a more distinctive alternative to the more popular brilliant pieces, where the top of the diamond, called the crown, is cut with round and bottom shapes, called the pavilion, is shaped similar to a cone. A princess cut in the same width as a brilliant spherical diameter will be heavier because it has four corners that should have been cut and rounded to form a brilliant spin. The princess piece is sometimes referred to as a brilliant modified square . However, while displaying a good level of brilliance, its faceting style is unique and completely different from its brilliant round. The Princess cut has its origins in the early "French" cut, has a crown cut "Double-French" or "Cross" step-modified and a series of unique, cheek-shaped facets in a pavilion that combine to give different cross shaped reflections when the stone is seen directly through the table. The Barion-shaped piece has now been renamed "Princess cut".
The diamond cut princess diamond is usually slightly cheaper than a brilliant round cut diamond of the same rust weight as it retains about 80% of the rough diamond, compared to a brilliant round that only retains about 50% of the rough. The ability to retain more crystalline weight makes this form popular among diamond cutters.
The US-based Gem Gem Accredited (AGA) and American Gem Society Laboratory (AGSL) and Gem Laboratories-USA (EGL-USA) are currently the only laboratories that rated Princess cut for cutting. Measurements vary for diamond cut diamonds and many diamond producers market the ideal diamonds with different aspects and angles as different "ideal pieces". In contrast to AGSL, AGA, and EGL-USA, the Gemological Institute of America (GIA) has stated that there is not enough industry consensus or empirical data to define the cut grading standards for Princess diamond cutting and to do so is at consumer risk that may be deceived by diamond accompanied by an Ideal or Excellent cut value that does not qualify.
The name "princess cut" was originally used in conjunction with another diamond cut, otherwise known as a "profile" cut, designed by Arpad Nagy, a London cutter, in 1961. The same name was later used and popularized by Ygal Perlman, Betzalel Ambar, and Israel Itzkowitz in Israel in 1979. The cut is similar to only 49 aspects, as opposed to the original 58 aspects of the princess cut, then branded as "Quadrillion" and originally distributed by Ambar Diamonds in Los Angeles. The three year optical research produces square stone with a look similar to a round brilliant rounded diamond.
The number of chevrons can affect the overall view of the diamond cut by the princess. This can usually be determined with a wire diagram plotted in the diamond valuation report.
By adding more chevron on the side of the diamond pavilion, each side of the diamond will now be split into smaller pieces. As a result, he can give a piece of diamond princess "a ruined ice look". Similarly, when the diamond cut princess has fewer chevrons, it tends to give the diamond a chunky look because of the wider aspect.
