Princess Cut Diamonds: A Distinctive Shape with Brilliant Sparkle
Also known as the modified square brilliant cut, the princess cut is a modern diamond cut developed during the 20th century. Today, it is one of the most popular square diamond shapes, featuring a square or slightly rectangular outline, sharp 90-degree corners, and an inverted pyramid-shaped pavilion. Its clean lines and geometric shape make princess-cut lab-grown diamonds a popular choice for engagement rings and a wide range of fine jewelry designs.
