The cushion cut has one quality almost no other shape can claim in the same way: it photographs beautifully in nearly any light, which is precisely why it has become a favourite for engagement rings that are going to spend the next several years in photographs.

Figures assume a standard square cushion cut. Elongated cushions run larger in one dimension for the same carat weight. As with any shape, an IGI certificate confirms a specific stone's actual measurements rather than relying on these averages.
Crushed Ice vs Chunky Facet Cushions
Modern cushion cuts fall into two distinct styles. A chunky facet cushion uses larger, more traditional facets that produce bold, clearly defined flashes of light, a more classic, vintage read. A crushed ice cushion uses smaller, more numerous facets that scatter light into a sparkling, textured surface with less distinct flash but more constant shimmer. Neither is objectively better. The choice comes down to whether you want bold flashes or a softer, all over sparkle.
Why Cushion Cuts Photograph So Well
The rounded corners and larger facet structure of a cushion cut catch and hold light differently than a sharply faceted shape, producing a warmer, more forgiving sparkle under artificial and flash photography specifically, where harder cut shapes can sometimes look flat or overly white.
Best Metal Pairings
Cushion cuts pair particularly well with rose and yellow gold, which soften the stone's already warm light output, though white gold remains a strong, more contemporary choice for a crushed ice cushion specifically.
