The princess cut is the second most popular cut shape for diamonds, next to a round brilliant.
 The face-up shape of the princess cut is square or rectangular and the profile or side-on shape is similar to that of an inverted pyramid with four beveled sides.
 The princess cut is a relatively new diamond cut, having been created in the 1960s.
 It has gained in popularity in recent years as a more distinctive alternative to the more popular round brilliant cut, in which the top of diamond, called the crown, is cut with a round face-up shape and the bottom, called the pavilion, is shaped similar to a cone.
 A princess cut with the same width as the diameter of a round brilliant will weigh more as it has four corners which would otherwise have been cut off and rounded to form a round brilliant.
 The princess cut is sometimes referred to as a square modified brilliant.
 However, while displaying a good degree of brilliance, its faceting style is unique and completely different from that of a round brilliant.
 The Princess cut had its origins in the early "French" cut, having a step-modified "Double-French" or "Cross" cut crown and a series of unique, chevron-shaped facets in the pavilion which combine to give a distinct cross-shaped reflection when the stone is viewed directly through the table.
 The Barion shaped cut has now been renamed the "Princess cut".
