Cushion Cut Engagement Rings

Soft corners and a pillow of light define the cushion cut. Our cushion cut engagement rings are made to order in our Los Angeles atelier, set with a natural or lab grown cushion diamond that is GIA or IGI certified.

One fair price, complimentary insured U.S. shipping, and a lifetime warranty against manufacturing defects.

The Cushion Cut

Cushion Cut Engagement Rings

A cushion cut diamond is a square or soft rectangle with rounded corners and brilliant facets, the shape that sat in most engagement rings before the round brilliant existed. It comes in two facet styles that look nothing alike: the antique cushion, with large facets that throw broad flashes of color, and the modern cushion, with small facets that sparkle like a round. Same outline, different diamond. Knowing which one you are looking at is the whole decision.

Every cushion cut ring here is made to order in our Los Angeles atelier, modeled around the measurements of the diamond you choose. Cushions vary more in outline than any other shape, from near square to pillow to elongated, so the seat and the prongs are built to the certificate rather than to a standard head.

One fair price

Each setting and each diamond carries a single price. No codes, no strikethroughs, no timing the purchase.

GIA or IGI certified

Natural cushion diamonds graded by GIA. Lab cushion diamonds graded by IGI. Our gemologist verifies every diamond against its certificate before it is set.

Resizing and warranty

60 day complimentary resizing, lifetime warranty, and the Ring Size Guide before you order.

Two ways to own one

Build your ring. Choose a cushion setting below, then pair it with a natural or lab cushion diamond from our inventory. A ROSI™ Score Report, our gemological intelligence, reads the cut performance and fair market position of any natural diamond you are considering, and tells you which facet style you are looking at. John Anderson, our Lead Gemologist, reviews the shortlist with you.

Choose a Select ring. The Select rings in this collection arrive complete, with an IGI certified lab cushion already matched to the setting in the carat weight you choose.

A cushion faces up smaller than an oval of the same weight and about the same as a round. It is not the shape to choose for spread. It is the shape to choose for the way light moves through it, and for a setting that looks like it was made eighty years ago. If spread is what you want, we will point you to the oval.

How to choose a cushion cut diamond

  • Antique or modern. Antique cushions (sometimes called chunky or old mine style) have a small table and large facets; they glow. Modern cushions have a crushed ice look of many small facets; they sparkle. Neither is better. Decide this first, because no setting changes it.
  • Ratio. 1.00 to 1.05 is a square cushion. 1.10 to 1.25 is elongated and lengthens the finger. The elongated cushion has been the most requested cushion in our atelier for the last few years.
  • Color. Cushions hold more body color than rounds. H or better faces up white in platinum and white gold; yellow and rose gold flatter down to J, and an antique cushion in yellow gold is the classic pairing.
  • Clarity. Crushed ice cushions hide inclusions well; VS2 and often SI1 are clean to the eye. Antique cushions with large facets show more, so stay at VS2 or better.
  • Setting. A halo makes a cushion the shape most people picture as vintage. A four prong solitaire shows the outline. A hidden halo keeps the top clean and adds light from the side. Bezels suit the softer outlines.

Two cushions with identical certificates can look like different shapes on the hand.

Frequently Asked Questions

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

A cushion is a square or rectangle with rounded corners; a round is a circle. Both use brilliant facets. A round shows the most sparkle of any shape. A cushion trades a little of that for a softer outline and, in the antique facet style, broad flashes of color a round cannot produce.

Does a cushion cut diamond cost less than a round?

At the same carat weight and grades, a cushion usually carries a lower price than a round, because less rough is lost in cutting it. At RockHer each diamond carries one fair price, and the ROSI™ report shows where that price sits against the market.

Does a cushion cut look bigger than a round?

About the same face up at equal weight, and a little smaller than an oval. An elongated cushion covers more of the finger than a square one. A halo adds spread if that is what you want.

What is a crushed ice cushion?

A modern cushion cut with many small facets below the table, so the diamond looks like broken glass or crushed ice when it moves. It sparkles constantly and hides inclusions well. The alternative is the antique or chunky cushion, with fewer, larger facets that produce distinct flashes.

Natural or lab cushion diamond?

Either. Both are certified, natural by GIA and lab by IGI, and both come in antique and modern facet styles. Lab cushions give you more carat for the same spend; natural cushions are rarer and hold their place in the market differently. The setting and the warranty are identical.

How long does a cushion cut engagement ring take to make?

8 to 12 business days from the day the diamond is confirmed. The CAD model is built around the measurements on the certificate, the diamond is verified against the certificate by our gemologist, and the ring is finished and inspected in Los Angeles before it ships insured.
