Cushion Cut Engagement Rings

Soft rounded corners and large, glowing facets give a cushion cut engagement ring a romantic, vintage feel. Solitaire and trilogy designs hold a lab-grown cushion diamond, with yellow, rose and white 18K gold or platinum to choose from.

What Is a Cushion Cut Diamond?

A cushion cut diamond has a square to slightly rectangular outline with rounded corners, like a pillow. The shape descends from the old mine cut of the 19th century, which gives it its vintage character. Because the corners are rounded, a cushion diamond ring is less prone to chipping than a stone with sharp points.

A square cushion has a balanced, classic look on the hand, while a slightly longer cushion leans towards the elegance of an oval. In a trilogy, the soft corners of the centre stone contrast with the sharper lines of side stones such as trilliants, which frame the cushion and make it look wider.

Every cushion cut lab grown diamond ring is graded colour D and VS1 clarity or better, with an IGI certificate on stones over 0.45ct, the same standard as all our lab diamond rings.

Cushion, Princess, Round or Oval

Each diamond shape has its own look and sparkle. Here’s how cushion cuts compare with princess, round and oval diamonds:

  • Cushion: rounded corners and broad flashes of light, for a softer look
  • Princess: the same square proportions with sharp corners and crisp sparkle, as on a princess diamond ring
  • Round: the most sparkle of any shape, in a circular outline
  • Oval: a longer shape with brilliant facets, as on an oval diamond engagement ring

The cushion sits between the princess and the round: it has the squared proportions of one and the softness of the other, which makes it a popular choice for someone who wants a classic ring with a touch of romance.

Cushion Cut Settings and Metals

Cushion cut diamonds work beautifully in different ring settings, whether you prefer a simple solitaire or a design with additional diamonds:

Every design comes in 18K yellow, white or rose gold or platinum, like all our solid gold engagement rings. A cushion cut diamond ring in white gold or platinum looks bright and crisp, while yellow and rose gold give it a warmer tone. The ring is then handcrafted in England in your chosen metal.

Frequently Asked Questions

Do cushion cut diamonds show inclusions more readily than round brilliant cuts?

A cushion cut can sometimes show inclusions more readily than round brilliant diamonds. This is why we select stones that have VS1 clarity so that our stones are eye clean.

Does a cushion cut look smaller than other shapes?

A cushion cut can look slightly smaller from above than a round or oval of the same carat weight, because more of its weight sits in its depth. A trilogy setting adds width.

What is the difference between a cushion cut and a princess cut?

Both are popular square diamond shapes, but a cushion cut has softly rounded corners, giving it a softer, more classic appearance. A princess cut has sharp, pointed corners and a more angular, contemporary look. Their different faceting patterns also create distinct patterns of light and sparkle.

Do cushion cut diamonds chip?

Rounded corners make a cushion cut less likely to chip than shapes with sharp points, such as the princess or marquise.

Are cushion cut engagement rings popular?

Yes. The cushion cut is one of the most popular fancy shapes for engagement rings, loved for its romantic, vintage look.
