If the round brilliant is the definitive diamond and the emerald cut is the architectural one, the cushion cut is the romantic one. Soft corners, a larger facet pattern, and a warmer, more diffused sparkle give the cushion cut a character that's unlike anything else.
What Is a Cushion Cut?
A cushion cut is a square or rectangular diamond with rounded corners — the silhouette resembles a pillow or cushion, hence the name. The facet pattern varies between cushion cuts more than any other shape, which means two cushion cuts of the same carat weight can look and sparkle quite differently. This makes buying in person particularly important.
Cushion Brilliant vs Cushion Modified
The two main cushion cut varieties produce noticeably different visual effects. The classic cushion brilliant has larger facets that produce a chunky, fire-forward sparkle — warm and distinctive. The modified cushion (sometimes called a "crushed ice" cushion) has smaller, more numerous facets that produce a sparkling, crushed-ice appearance closer to a round brilliant. Neither is better — they're just different looks. Try both.
Why People Love Cushion Cuts
The cushion cut has been popular for over a century — it was actually the most common diamond shape before the round brilliant was developed in the early 1900s. Its enduring appeal comes from its warmth. Cushion cuts show more fire (colored light dispersion) than rounds, giving them a particularly beautiful look in candlelight and warm indoor settings. They feel romantic in a way that more precise shapes don't.
Settings That Work With Cushion Cuts
Cushion cuts work beautifully in halo settings — the soft shape and the round accent diamonds complement each other naturally. They also look stunning in simple four-prong solitaires where the shape can speak for itself. Pavé bands add sparkle without competing with the center stone.
Sizing Considerations
Square cushion cuts (length-to-width ratio close to 1.00) are bold and geometric. Rectangular cushions (1.10–1.20 ratio) are more elongated and slightly more flattering on longer fingers. Personal preference and hand shape should guide the choice.
