The cushion cut diamond combines a square or rectangular outline with rounded corners and brilliant-cut faceting — creating a warm, romantic stone with vintage character. This guide covers everything about the cushion cut.
The cushion cut is a square or slightly rectangular diamond with rounded corners — like a pillow or cushion, which gives it its name. It is a brilliant cut, meaning the facets are triangular and kite-shaped rather than rectangular steps. The cushion cut is older than the round brilliant — its origins lie in the old mine cut of the 18th and 19th centuries — and it carries a warmth and vintage character that the more precisely optimised round brilliant does not.
The cushion cut is available in two main variants at Fenora: standard cushion (larger facets, chunkier light performance, closer to the original old mine cut character) and cushion modified brilliant (smaller facets, more sparkle, more like a round brilliant in a cushion outline). A third variant — elongated cushion — is covered in its own guide.

|---|---|---|
| Facet pattern | Larger, more open facets — closer to old mine cut | Smaller additional facets in the pavilion — more sparkle |
| Sparkle character | Chunky, defined flashes — warmer and more romantic | Brighter, more numerous smaller flashes — more brilliant |
