The two other options that are most similar to a princess cut diamond are a radiant cut diamond and a cushion cut diamond.
Radiant cut diamonds are very similar to the princess cut with straight sides but they have beveled corners like an emerald cut diamond, making them an octagon instead of a square or rectangle. The radiant has many facets with a “crushed ice” appearance with slivers of brilliance. Although the cut corners make it less likely to chip, the radiant cut can concentrate color. It may appear a little less colorless than a princess cut of the same color grade.
A cushion cut diamond is another option for those who love the princess cut because it is more square than a round brilliant. Instead of the princess cut’s straight sides and ninety-degree corners, a cushion has rounded sides and corners. Cushion cut diamonds can be very brilliant. The best cushion cuts will display the hearts and arrows pattern in a light-performance viewer. A hearts-and-arrows cushion like RockHer’s Cushion Brilliant designed by master cutter Brian Gavin, is a great way to get the precision cutting and high light performance of a hearts and arrows round brilliant
for less per carat.
