The princess cut is a square brilliant-cut diamond with sharp corners and maximum sparkle. Second only to round brilliant in popularity, the princess delivers the brilliance of a round in a geometric square format. This guide covers everything about the princess cut.
The princess cut was developed in the 1960s and refined through the 1980s. It is a square or very slightly rectangular diamond with sharp corners, cut with brilliant-style faceting that produces maximum sparkle in a square format. The princess has the visual geometric precision of a square with the light performance approach of a round brilliant.
The four sharp corners of the princess cut are its defining characteristic — and its primary practical consideration. Sharp corners concentrate stress and are the most vulnerable areas of the stone. Corner prong protection is essential in any princess cut setting.
