A cushion cut lab grown diamond engagement ring pairs a soft, pillow shaped outline with large, bright facets.

What makes a beautiful cushion

Outline and ratio

Cushions vary more than any other shape. Some are almost square with gently rounded corners; others are noticeably rectangular. Decide on the outline you like before comparing grades, and use the 360 degree video to see it from directly above.

Faceting style

Some cushions have a crushed ice look, with many small, broken flashes. Others show larger, distinct facets, closer to an antique cut. Neither is better; it is a matter of taste, and the difference is easy to see in the video.

Color

Cushions tend to hold color more than rounds. G color or better looks white in platinum and white gold. In yellow and rose gold, H and I still look lovely, since the warm metal masks any tint.

Clarity

The large facets can show inclusions more easily than a round brilliant. VS2 is a safe target; with SI1, check the center of the stone carefully in the video before choosing.

Settings that suit the shape

The setting decides how a cushion cut lab grown diamond engagement ring reads on the hand. A four prong solitaire keeps the focus on the soft outline. A halo follows the curves and adds a lot of visual size, the classic pairing for this shape. A hidden halo gives side sparkle with a clean top view. Three stone designs with smaller cushions or rounds on each side give a balanced, heirloom feel.

Lab grown or natural?

Lab grown cushions are identical to mined stones in look and hardness. Because a cushion cut lab grown diamond engagement ring costs far less per carat, buyers often choose a larger center or better color. A natural cushion suits buyers who want mined origin, but at the same size and grades it will cost several times more.

Where Rare Carat shines

Rare Carat offers a wide selection of complete cushion rings in every major setting, with 99 designs ready to order in 4 metals. Every ring is filmed in 360 degree video so you can check the outline and faceting before you buy, and returns are accepted within 30 days. The resizing policy explains sizing after delivery.

Cushion Cut Lab Grown Diamond Engagement Rings: frequently asked questions

What is a cushion cut diamond?

A square or rectangular diamond with rounded corners and curved sides, like a pillow. It has large facets that give bold flashes of light and a soft, romantic look.

Square or elongated cushion?

A square cushion, with a ratio near 1.00 to 1.05, looks classic and vintage. An elongated cushion, around 1.15 to 1.30, looks slimmer on the finger and a little more modern.

Are cushion cuts less sparkly than rounds?

They show broader, chunkier flashes rather than the fine pinpoint sparkle of a round. Modern cushions with extra facets sparkle more; older style cushions glow.

How much does a cushion cut engagement ring cost?

The typical complete ring here costs about $1,695, with most between $1,515 and $1,930. Carat weight and setting style account for most of the spread.

Does a cushion need a halo?

No. A cushion looks beautiful in a simple four prong solitaire. A halo is popular because it follows the soft outline and makes the center look larger.
