The cushion cut diamond is one of the most romantic and enduring diamond shapes in the world. With its softly rounded corners and pillow-like silhouette, this cut has been captivating buyers for over two centuries. It is also one of the most popular choices we see at Golden Anvil Jewelers, where our GIA-certified gemologists help clients across Jupiter, Palm Beach County, and South Florida find their perfect stone every day.

But choosing a cushion cut is not as straightforward as picking a round brilliant. There are different types of cushion cuts, no standardized cut grading from GIA, and a wide range of visual appearances that can make shopping feel overwhelming. This guide breaks it all down so you can buy with confidence.

A Brief History: From Old Mine Cut to Modern Cushion

The cushion cut's story begins in the 1700s with the old mine cut, a hand-cut diamond shape designed to sparkle beautifully under candlelight in grand European ballrooms. These early stones featured a squarish outline, high crown, small table, deep pavilion, and a large open culet at the bottom of the stone.

The name "old mine cut" actually came later, after diamonds were discovered in South Africa in the late 1800s. The earlier Brazilian sources became known as the "old mines," and the diamonds from those mines kept the name. According to the Gemological Institute of America (GIA), these hand-cut stones had 58 facets and a distinctly chunky, warm appearance that collectors still prize today.

As cutting technology advanced through the 20th century, diamond cutters refined the old mine cut into what we now call the modern cushion cut. The shape kept its signature pillow-like outline but gained more precise faceting, better symmetry, and enhanced brilliance. Today's cushion cuts typically feature 64 facets, delivering noticeably more sparkle and fire than their antique ancestors while retaining that timeless, romantic character.

Types of Cushion Cuts: Standard Brilliant vs. Modified Brilliant

This is one of the most important distinctions in cushion cut shopping, and it is where many buyers get confused. When you look at a GIA grading report, you will see one of two designations: Cushion Brilliant or Cushion Modified Brilliant. Here is what each means.

Cushion Brilliant (Standard)

The cushion brilliant is the original modern cushion cut. It features larger, chunkier facets that produce broad flashes of light, similar to the facet pattern you would see in a round brilliant diamond. If you hold a cushion brilliant face-up and look through the table, you will see a clearly defined, organized pattern of light and dark.

Cushion Modified Brilliant

The cushion modified brilliant was developed in the 1920s and has shorter pavilion mains with extra facets added below the girdle. This different faceting arrangement can produce a variety of visual appearances, from chunky patterns similar to the standard brilliant to the popular "crushed ice" look.

Chunky vs. Crushed Ice: What You Really Need to Know

Here is a common misconception we correct for clients regularly: the "chunky" versus "crushed ice" appearance is not determined by whether a diamond is a cushion brilliant or cushion modified brilliant. Both categories can produce either look.

Appearance	Description	Best For
Chunky	Clearly defined, broad facets with distinct flashes of light. Resembles the facet pattern of a round brilliant.	Buyers who love bold, organized sparkle with a vintage feel
Crushed Ice	No clearly defined facet pattern. An all-over glitter effect that resembles sparkling water or broken ice.	Buyers who prefer a modern, dispersed shimmer

The only reliable way to determine whether a specific cushion cut has a chunky or crushed ice appearance is to view the diamond in person or through high-quality video. This is one of the reasons we always encourage clients to visit our Jupiter showroom or work directly with our gemologists. On paper, two cushion modified brilliants with identical grades can look dramatically different.

It is worth noting that the vast majority of cushion cuts on the market today are modified brilliants. Diamond cutters prefer this approach because it produces less waste from the rough crystal, which is also why modified brilliants tend to be slightly less expensive than standard cushion brilliants.

Ideal Proportions for Cushion Cut Diamonds

Unlike round brilliant diamonds, cushion cuts do not receive a cut grade from GIA or AGS. This means you cannot simply look for "Excellent" or "Ideal" on a grading report. Instead, you need to evaluate proportions yourself, or better yet, work with a knowledgeable gemologist who can assess the stone's light performance.

Here are the proportion ranges our team recommends based on decades of experience:

Parameter	Ideal Range	Acceptable Range
Depth	65% to 69%	64% to 70%
Table	59% to 63%	57% to 65%
Length-to-Width Ratio (Square)	1.00 to 1.05	1.00 to 1.10
Length-to-Width Ratio (Elongated)	1.15 to 1.20	1.10 to 1.30
Polish	Excellent or Very Good	Very Good
Symmetry	Excellent or Very Good	Very Good

A Note on Length-to-Width Ratio

The ratio you choose depends on whether you want a square or rectangular cushion. For a square look, stay at or below 1.05. For an elongated cushion, commit to 1.15 or above. We recommend avoiding the 1.06 to 1.10 range, where the stone does not look quite square or quite rectangular. It ends up in an awkward in-between that often feels visually off, as noted by industry experts.

Elongated cushion cuts have become increasingly popular in recent years. They create a flattering, finger-lengthening effect on the hand and offer a distinctive look compared to the classic square shape. However, rectangular cushion cuts with ratios above 1.30 can sometimes develop a slight bow-tie effect, a shadow across the center of the diamond caused by light obstruction. Keeping the ratio below 1.30 typically avoids this issue.

Color Recommendations for Cushion Cuts

Cushion cut diamonds tend to retain and display body color slightly more than round brilliants. The broad facets and deeper pavilion hold warmth in a way that some buyers love and others prefer to minimize. Here is our guidance based on your setting metal:

Metal Type	Recommended Color Grade	Budget-Friendly Option
Platinum / White Gold	G or H	I
Yellow Gold	I or J	K
Rose Gold	H or I	J

For most of our Jupiter and Palm Beach County clients, we find that H color represents the best balance of beauty and value for cushion cuts in white metal settings. At this grade, any warmth is virtually undetectable once the diamond is set, yet the savings compared to D, E, or F color can be substantial.

If you actually enjoy a touch of warmth in your diamond, there is nothing wrong with choosing I or even J color. Some of the most beautiful cushion cut engagement rings we have created at Golden Anvil Jewelers feature slightly warmer stones that pair gorgeously with yellow or rose gold.

Clarity Recommendations

The brilliant faceting pattern of a cushion cut does an excellent job of masking minor inclusions, which is great news for value-conscious buyers. However, cushion cuts also have a relatively large, open table, so the location of inclusions matters.

Our recommendation: target VS2 or SI1 clarity, and always confirm that the diamond is eye-clean. At these grades, you are paying for beauty you can actually see, not microscopic perfection that only shows up under 10x magnification.

For crushed ice cushion cuts specifically, the scattered light pattern can be particularly forgiving of small inclusions, sometimes allowing you to go as low as SI1 without any visible compromise. Chunky cushion cuts, with their broader facets, may require slightly higher clarity to ensure eye-cleanliness.

As recommended by Kwiat and our own gemologists, the VS1 to SI1 range is the sweet spot, provided the SI1 appears clean to the naked eye.

Price: How Cushion Cuts Compare to Other Shapes

One of the biggest advantages of choosing a cushion cut is value. Because cushion cuts waste less rough diamond material during the cutting process, they are meaningfully less expensive than round brilliants of comparable quality.

Here is a general price comparison for a well-cut 1.5 carat diamond with G color and VS2 clarity:

Diamond Shape	Approximate Price Range	Savings vs. Round
Round Brilliant	$9,000 to $14,000	Baseline
Cushion Cut	$5,500 to $9,500	25% to 40% less
Oval	$6,000 to $10,000	20% to 35% less
Princess	$5,500 to $9,000	25% to 40% less

Note: Prices vary based on exact proportions, fluorescence, and market conditions. These ranges reflect 2025-2026 market data for natural diamonds.

That savings can go a long way. Many of our clients use the price difference to upgrade to a larger carat weight, choose a more elaborate setting, or invest in higher color or clarity. At Golden Anvil Jewelers, we help you find the combination that gives you the most beautiful diamond for your budget.

Best Settings for Cushion Cut Diamonds

The setting you choose can dramatically change the way your cushion cut diamond looks and feels on the hand. Here are the most popular options we recommend:

Solitaire

The classic solitaire lets the cushion cut's pillow shape and brilliant faceting take center stage. This is a timeless choice that works equally well for square and elongated cushions. It is also the most low-maintenance option, with fewer prongs and crevices to catch on clothing. Because solitaire settings are among the least expensive styles, more of your budget can go toward the center stone.

Halo

A halo of smaller diamonds surrounding the cushion cut center stone amplifies its visual size and adds extra sparkle. This is one of the most requested combinations we see at our Jupiter showroom. A halo can make a 1.00 carat cushion look closer to 1.50 carats, making it an excellent option for buyers who want maximum impact.

Three-Stone

Flanking the cushion cut with two side stones (often half-moon, trapezoid, or smaller cushion shapes) creates a balanced, meaningful design. Many couples choose three-stone settings to represent past, present, and future.

Pave Band

A thin band of micro-set diamonds adds continuous sparkle and creates a seamless flow of light from band to center stone. Pave settings pair beautifully with both chunky and crushed ice cushion cuts.

Frequently Asked Questions

Is a cushion cut diamond a good choice for an engagement ring?

Absolutely. Cushion cuts are one of the most popular shapes for engagement rings, and for good reason. They combine vintage charm with modern brilliance, they face up nicely for their carat weight, and they cost significantly less than round brilliants. Their rounded corners also make them a practical choice, as there are no sharp edges that could chip or snag.

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

Both shapes have a rectangular or square outline with brilliant faceting, but the radiant cut has cropped corners rather than the softly rounded corners of a cushion cut. Radiant cuts also tend to have a more uniform "crushed ice" sparkle pattern, while cushion cuts offer more variety in their light performance.

Do cushion cut diamonds look smaller than round diamonds of the same carat weight?

Cushion cuts can appear slightly smaller face-up than rounds of the same carat weight because cushions tend to carry more weight in their depth. This is why proportions matter so much. A well-cut cushion with appropriate depth (65% to 69%) will minimize this effect. Choosing a halo setting can also help maximize the perceived size.

Should I choose a chunky or crushed ice cushion cut?

This is entirely personal preference. Chunky cushion cuts produce bold, defined flashes of light that many people associate with traditional diamond sparkle. Crushed ice cushion cuts create an all-over shimmer that looks more contemporary. We always recommend viewing both styles in person before deciding. Our gemologists at Golden Anvil Jewelers are happy to show you examples of each so you can see which speaks to you.

Can I see a bow-tie effect in a cushion cut diamond?

Square cushion cuts (ratio 1.00 to 1.10) do not produce a bow-tie effect. However, elongated cushion cuts with higher length-to-width ratios can sometimes show a slight bow-tie shadow across the center. Keeping the ratio below 1.30 and selecting a well-proportioned stone will minimize or eliminate this issue entirely.

How much should I spend on a cushion cut diamond engagement ring?

There is no universal rule. At Golden Anvil Jewelers, we work with budgets of every size and focus on finding the best quality within your comfortable range. A beautifully cut 1.00 carat cushion in the H color, VS2 clarity range can be found starting around $3,500 to $5,000 for the loose stone. Settings add additional cost depending on complexity and metal type. We are always transparent about pricing and happy to walk you through your options.
