Princess Cut Engagement Rings: Modern Sparkle, Timeless Shape

The princess cut is the most popular square shape in engagement rings — and for good reason. It blends the brilliance of a round diamond with a sharp, modern silhouette that feels both classic and current.

This guide explains what makes a princess cut special, how it compares to similar shapes, and how to choose a quality stone.

What Is a Princess Cut?

A princess cut is a square or near-square brilliant-cut stone with pointed corners and a high crown. It was designed to maximize fire and brilliance from a square outline — essentially, it brings round-cut sparkle to a geometric, modern silhouette. Because it wastes very little of the rough crystal, it is also an efficient shape, which helps with value.

Princess Cut vs Cushion vs Emerald

Princess vs cushion — cushions have rounded corners and a softer, vintage feel; princess cuts are sharp and modern. See our cushion cut guide.
Princess vs emerald — emerald cuts are step-cut and understated; princess cuts are brilliant and lively. See our emerald cut guide.
Princess vs round — rounds are the sparkliest shape, but princess cuts offer a similar fire in a more distinctive, modern square.

Best Settings for a Princess Cut Ring

Solitaire — the sharp corners shine on a clean band.
Prong or V-prong — the pointed corners need protection, so ask for a V-shaped prong to guard them.
Halo — accent stones soften the corners and add size. Read our halo guide.
Pavé band — a line of small stones echoes the square’s clean geometry.

How to Choose a Princess Cut Moissanite

Symmetry — corners should align and the outline should be square, not rectangular.
Facet pattern — classic step-like brilliance or crushed-ice; try both if you can.
Color — a colorless D–F moissanite reads as white; colored stones like moonstone or blue sapphire make it one-of-a-kind.
