Princess-cut moissanites are defined by a square outline, sharp corners, and lively faceting. The best stones combine symmetry, balanced brightness, a centered pattern, and enough corner integrity for secure setting.

Square proportions

Check the length and width. A ratio close to 1.00 creates a true square, while a noticeable difference can make the stone appear slightly rectangular.

Corner symmetry

All four corners should appear even and aligned. Because princess corners are vulnerable, the stone should be set with protective prongs, often V-prongs or carefully fitted claws.

Facet pattern and center

The center should look balanced rather than forming a distracting dark cross, empty window, or uneven patch. Movement should create lively contrast across all four quadrants.

Depth and spread

A princess cut can hide significant depth beneath the setting. Compare face-up millimeter size because two stones with similar carat equivalent may show different visible coverage.

Brightness at the corners

Some princess cuts lose light near the corners. Slight contrast is normal, but the corners should not remain persistently dull compared with the center.

Setting compatibility

Precise measurements matter because the stone’s corners must align with the head or basket. A setting should support the stone without leaving exposed corners.

Frequently asked questions

Should a princess cut be perfectly square?

For a classic princess appearance, yes. Slight rectangular proportions may still be attractive when intentionally chosen.

Are princess cuts suitable for everyday wear?

They can be, provided the sharp corners are properly protected and the wearer avoids severe impact.
