Princess

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.
