Princess Cut Diamonds
48 certified princess cut diamonds available
The princess cut is the square answer to the round brilliant: a modern profile with crisp corners and lively, linear sparkle. Invented in the 1960s, it remains the most popular square shape for engagement rings.
Because the cut preserves up to 80% of the rough crystal, princess diamonds are consistently priced well below rounds. Its pointed corners need a protective setting — a four-prong with corner coverage or a bezel keeps them safe for decades.

Are princess cut diamonds durable?+
The stone itself is as hard as any diamond, but the four pointed corners concentrate impact. Choose settings with corner-protecting prongs and it will wear beautifully for a lifetime.
Why are princess cuts good value?+
The shape follows the natural octahedral rough closely, wasting little material, so cutters can price it 25–35% under rounds of equal quality.
What ratio should a princess cut be?+
1.00–1.05 reads as a perfect square. Above 1.08 the stone visibly rectangles; some prefer that, but confirm it is intentional.
