Cushion Cut Engagement Rings

The cushion cut is the softest square in diamonds — a pillow-edged outline with over a century of history, cut with large facets that throw broad, chunky flashes of fire. Its fastest-rising form is the elongated cushion cut, a stretched version that wears like an oval with the cushion's vintage character. Our cushion cut engagement rings run from $945 to $6,714 across 152 designs.

Cushion cut diamond ring styles

A cushion cut diamond ring suits every setting: a plain solitaire, a size-boosting halo (the pairing the shape is famous for), or elongated cushion cut engagement rings worn east-west for a modern spin.

Why lab-grown suits the cushion

A cushion cut diamond retains colour more than most shapes, so higher colour grades matter — and lab-grown pricing puts those grades within reach, IGI-certified, at a fraction of mined cost.

Crushed ice or chunky — the cushion cut decision

Every cushion belongs to one of two families. "Chunky" cushions carry large, defined facets that flash like a round brilliant — you can trace the pattern with your eye. "Crushed ice" cushions splinter light into hundreds of tiny glints, like sun on snow, with no readable pattern. Neither is better; they are different personalities, and photographs flatten the difference — always judge from video.

On colour, the cushion's deep corners recycle light in a way that concentrates body colour, so step one grade higher than you would for a round: H or better keeps the stone reading white in yellow-gold settings, G or better in white metal. Face-up, expect a square cushion to show slightly smaller than a round of equal weight — the corners carry hidden depth — which is one more argument for the elongated versions.

Cushion cut FAQs

What is a cushion cut diamond?

A square or slightly rectangular outline with rounded, pillow-like corners — the cushion cut descends from the 19th-century "old mine cut" and throws broad, chunky flashes rather than pin-fire sparkle.

What is an elongated cushion cut diamond?

An elongated cushion cut diamond stretches the classic square into a longer rectangle — it wears like an oval, looks larger per carat, and is currently the fastest-growing cushion variant.

Is an elongated cushion more expensive?

Usually the opposite — the elongated cushion often prices below a round of equal weight while showing more face-up size, which is a large part of its popularity.

Does a cushion cut ring sparkle less than a round?

Differently, not less — a cushion cut ring trades some white-light brilliance for bigger, more colourful flashes of fire. "Crushed ice" cushions glitter; "chunky" cushions flash.

What setting suits a cushion best?

The halo is the cushion's signature pairing — the soft square inside a diamond frame is one of the most requested combinations in bridal jewellery.

Cushion vs princess — which square should I pick?

Corners decide it: the cushion is soft and vintage, the princess sharp and contemporary. Sparkle is comparable; the personalities are opposites.
