Cushion cut engagement rings have a soft, romantic glow. With rounded corners and large facets, the cushion cut looks like a little pillow of light and has been loved for more than a century. Today you can choose between classic square cushions and fashionable elongated cushions.
This guide explains the different cushion styles, what to look for and the settings that suit them best. For a full comparison of shapes, see engagement ring shapes.
What is a cushion cut diamond?
A cushion cut is a square or rectangular diamond with rounded corners and gently curved sides. It descends from the old mine cut used in the 19th century, which was designed to sparkle by candlelight. Modern cushions are brilliant cuts with strong fire, meaning colorful flashes of light.
Cushion styles: crushed ice vs antique
- Modified brilliant ("crushed ice"): many small facets create a sparkly, glittery look. Popular, but the pattern can hide or blur the stone's depth.
- Standard or antique-style ("chunky"): larger, more defined facets create bold flashes, similar to vintage stones.
Grading reports do not always separate these styles, so judge them visually with photos or video.
Square vs elongated cushion
| Style | Typical ratio | Look |
|---|---|---|
| Square cushion | 1.00 to 1.05 | Classic, vintage |
| Slightly rectangular | 1.05 to 1.15 | Soft, balanced |
| Elongated cushion | 1.15 to 1.30+ | Modern, finger-lengthening |
Pros and cons
| Pros | Cons |
|---|---|
| Excellent fire and romantic look | Can look smaller face-up than a round of the same weight |
| Rounded corners resist chipping | Cut quality varies widely |
| Often lower price per carat than round | Can show color more than round |
| Square and elongated options | Crushed ice style is not to everyone's taste |
Clarity and color
- Clarity: brilliant faceting hides small inclusions; SI1 to VS2 stones are often eye-clean.
- Color: cushions can hold a little color. G to H suits white metals; warmer grades can look lovely in yellow gold for a vintage feel.
