Short answer: Cushion cut moissanite has a soft square or rectangular shape with rounded corners and large facets that create bold flashes of light and fire. It suits vintage and romantic styles especially well. Choose a length-to-width ratio of about 1.00 to 1.05 for a square look or 1.10 to 1.20 for a slightly elongated look. Popular settings include halos, hidden halos, cathedral mounts and simple solitaires.
Cushion cuts combine old-world charm with modern sparkle. They have been loved for generations because their pillow-like outline looks soft on the hand while their facets throw light in broad, dramatic flashes. In moissanite, that effect is even stronger. This guide explains how cushion cuts differ from one another, which ratio and size to choose, which settings flatter them, and how to care for the ring once it is yours.
What Is a Cushion Cut?
A cushion cut is a square or rectangular stone with rounded corners and gently curved sides, a bit like a pillow, which is where the name comes from. It sits between the round brilliant and the more angular princess and radiant cuts: softer than a square, more structured than an oval.
The cut has deep roots in antique jewelry. Older cushion-shaped stones were cut by hand to follow the rough crystal and keep as much weight as possible, which gave them chunky facets and a warm, glowing look. Modern cushion cuts are cut with far more precision, but many still borrow that vintage character.
Two main faceting styles
- Chunky or antique style: fewer, larger facets that create big, distinct flashes of light. This look feels vintage and shows clear facet patterns when you look into the stone.
- Crushed ice or modified brilliant style: extra small facets on the lower half of the stone break light into many tiny sparkles, giving a glittering look that some people compare to crushed ice.
Neither style is better; it comes down to taste. If you love the look of old jewelry, the chunky style is a good match, and you can see related designs among moissanite antique cuts. If you want maximum glitter, a crushed ice cushion delivers it.
Square vs Elongated Cushion
The length-to-width ratio decides whether your cushion looks square or rectangular. Divide the length by the width: 1.00 is a perfect square, and higher numbers are longer.
| Ratio | Shape | Look |
|---|---|---|
| 1.00 to 1.05 | Square cushion | Classic, balanced, vintage |
| 1.10 to 1.20 | Elongated cushion | Slimming, modern, larger look |
| Above 1.20 | Long cushion | Dramatic and distinctive, close to an oval outline |
Which ratio suits your hand?
- Shorter or wider fingers: an elongated cushion set north-south (pointing up the finger) helps lengthen the look.
- Long, slim fingers: a square cushion looks balanced and full without overwhelming the finger.
- Undecided: a ratio around 1.05 to 1.10 reads as a "soft square" and suits most hands.
Tip: Two cushions with the same carat weight can look quite different in size if their ratios differ. Always compare the millimeter dimensions, not just the weight, when you are choosing between stones.
Why Cushion Moissanite Sparkles So Much
Cushion cuts have larger facets than round brilliants, which create broad flashes of light. Combined with moissanite's high dispersion, cushions show vivid, chunky fire, especially in sunlight.
Here is what is happening. Moissanite has a refractive index of about 2.65, higher than diamond's 2.42, so it bends light strongly and looks very bright. It also has strong dispersion, which means it splits white light into spectral colors. Large cushion facets act like windows that show those colors in big, vivid patches rather than tiny pinpoints.
Moissanite is also doubly refractive, which can make the back facets appear doubled when you look through the stone at an angle. Good cutters orient the stone to minimize this when viewed from the top, so in a well-cut cushion it is rarely noticeable to the eye.
Indoor vs outdoor sparkle
Under soft indoor lighting, a cushion moissanite looks bright and white with gentle flashes. In direct sunlight or under spotlights, the rainbow fire becomes much more obvious. Some people love the strong color; others prefer a more restrained look and choose a smaller stone or a white gold setting that keeps the overall effect cool and crisp.
Choosing Size and Color
Moissanite is slightly less dense than diamond, so it is usually sold by millimeter size or by diamond equivalent weight (DEW), which tells you the size a diamond of that look would weigh. Shopping by millimeters is the most reliable way to know how large the stone will appear.
Size
- Everyday and understated: a modest cushion with a hidden halo looks refined and practical.
- Classic statement: a mid-size cushion in a solitaire or halo is the most common engagement choice.
- Bold: larger cushions show the most fire. Choose a lower profile setting to keep the ring comfortable.
Color
Moissanite is graded on a diamond-style color scale. D to F looks icy white and is the usual choice for white gold. G to I can show a faint warmth in larger sizes, which can look lovely in yellow or rose gold and especially suits the vintage feel of a cushion. Clarity is rarely a concern with moissanite; stones sold for fine jewelry are typically eye-clean.
Popular Cushion Ring Settings
Cushion cuts are versatile, which is one reason they work in so many ring styles. These are the settings shoppers choose most.
- Classic halo: adds size and a vintage frame.
- Hidden halo: clean from the top, sparkling from the side.
- Cathedral: raises the stone gracefully on arched shoulders.
- Wide pave band: bold and luxurious.
- Minimalist solitaire: lets the cushion shine alone.
- Three stone: a cushion center with side stones such as baguettes, trillions or smaller cushions for a fuller look.
A halo is the most traditional partner for a cushion. The frame of small stones echoes the cushion outline and makes the center look larger. Explore moissanite halo rings if you want maximum presence.

Halo vs hidden halo
A classic halo sits around the cushion on the top of the ring, so it is visible from every angle and makes the whole head look noticeably larger. It suits buyers who want a big, glamorous look and a strongly vintage feel. A hidden halo sits just below the cushion, under the girdle. From above you see only the center stone, but from the side a ring of small stones catches the light. It suits buyers who want a clean, modern top view with a little surprise sparkle.
Practically, a hidden halo is also slightly easier to pair with a straight wedding band, because the head of the ring is narrower at finger level.
Settings by lifestyle
- Hands-on work or sport: a bezel or low-set four-prong solitaire keeps the cushion protected and snag-free.
- Office and everyday: a cathedral solitaire or hidden halo balances sparkle with practicality.
- Special statement: a classic halo with a pave band gives the most sparkle per square millimeter.
Prongs for cushion cuts
Cushions are usually held with four prongs, one at each corner, which protects the corners and gives a clean square look. Double-claw prongs (eight in total) add security and a slightly vintage touch. For a very active lifestyle, a bezel around the whole stone offers the most protection.
Metal choice
- Yellow gold: warm and traditional, it brings out the antique feel of a cushion.
- Rose gold: soft and romantic, it pairs well with vintage-inspired halos and milgrain details.
- White gold: bright and modern, it keeps a colorless cushion looking as white as possible.
We set cushion moissanite in 10K, 14K and 18K gold. 14K is a common choice for daily wear because it balances rich color with good scratch resistance.
Cushion vs Other Shapes
- vs round: cushions feel more vintage and romantic.
- vs radiant: cushions are softer; radiants are crisper and more geometric.
- vs oval: ovals look longer; cushions look fuller.
| Shape | Outline | Sparkle style | Best for |
|---|---|---|---|
| Cushion | Soft square, rounded corners | Broad flashes, strong fire | Vintage and romantic rings |
| Round | Circle | Even, balanced brilliance | Timeless classics |
| Radiant | Square or rectangle, cut corners | Bright, lively, crisp | Modern geometric designs |
| Oval | Elongated ellipse | Bright with a longer look | Making fingers look slimmer |

How to Judge a Cushion Before You Buy
Cushion cuts vary more from stone to stone than most shapes, because there is no single standard recipe for the outline or facets. That makes it worth looking closely at photos and videos before you choose.
- Check the outline: the sides should curve gently and evenly. Corners that are too sharp make the stone look like a radiant; sides that bulge too much make it look puffy.
- Look for symmetry: the stone should look balanced from left to right and top to bottom, with the facet pattern mirrored on each side.
- Watch for a dark center: a cushion cut too deep or too shallow can show a darker area in the middle or a "window" where light passes straight through. A well-cut stone looks bright across its whole face.
- Ask for video: a short video shows how the stone moves and flashes, which a still photo cannot. It is the best way to see whether you prefer chunky or crushed ice faceting.
- Confirm the dimensions: ask for length, width and depth in millimeters, then work out the ratio yourself so you know whether the stone reads as square or elongated.
If you are buying online, a virtual appointment is a quick way to see the stone moving under different lights and ask questions in real time.

Cushion Moissanite vs Cushion Lab Grown Diamond
Many shoppers compare a cushion moissanite with a cushion lab grown diamond. Lab grown diamonds are real diamonds, chemically, physically and optically the same as mined diamonds, grown using the CVD or HPHT method. Moissanite is a different gemstone. Both make excellent cushion rings.
| Factor | Cushion moissanite | Cushion lab grown diamond |
|---|---|---|
| Material | Silicon carbide | Carbon (real diamond) |
| Hardness (Mohs) | About 9.25 | 10 |
| Refractive index | About 2.65 | About 2.42 |
| Look | Bolder rainbow fire | Whiter, more classic brilliance |
| Grading | Seller grade on a diamond-style scale | Often IGI or GIA graded |
| Budget | Lowest cost for a large stone | Higher cost at the same size |
Choose moissanite if you want a large cushion with vivid fire at a gentler price. Choose lab grown diamond if you prefer diamond's classic look and want an independent grading report. You can compare both in our lab diamond cushion range.
Wedding Bands for Cushion Rings
Most cushion solitaires and cathedral settings sit high enough for a straight band to slide underneath and rest flush. Halos are wider, so check that the halo does not overhang the band.
- Straight band: works with most solitaires and hidden halos.
- Curved or contour band: wraps around a wide halo for a snug fit.
- Pave or eternity band: adds sparkle and matches pave engagement rings.
- Plain metal band: lets the cushion stay the focus.

Caring for Cushion Moissanite
Moissanite is about 9.25 on the Mohs scale, so it resists scratches very well. What dulls any stone is a film of oil, lotion and soap on the back facets, which blocks light. Cushions have wide facets, so they show buildup quickly, and they look brilliant again just as quickly after a clean.
- Weekly clean: soak for a few minutes in warm water with mild dish soap, then brush gently under the stone with a soft toothbrush.
- Rinse and dry: rinse in clean water and pat dry with a lint-free cloth.
- Yearly check: have a jeweler inspect the corner prongs, since they protect the most exposed part of the stone.
- Remove for heavy tasks: take the ring off for the gym, gardening and harsh cleaning products.
Tip: If your cushion ring has a halo, brush the underside of the halo too. Dirt trapped there dims both the small stones and the light reaching the center stone.

1.00 to 1.05 for square, 1.10 to 1.20 for elongated. Around 1.05 to 1.10 gives a soft square that suits most hands.
Is a cushion cut vintage?
It has vintage roots but looks great in modern settings too, such as hidden halos and sleek solitaires.
Does a cushion look smaller than a round?
Slightly at the same weight; a halo compensates. Comparing millimeter sizes gives the clearest picture.
What metal suits cushion rings?
Yellow and rose gold enhance the vintage feel; white gold looks crisp.
What is a crushed ice cushion?
A cushion with extra small facets on its lower half, which breaks light into many tiny sparkles instead of a few large flashes.
Is cushion moissanite durable enough for daily wear?
Yes. At about 9.25 on the Mohs scale, moissanite resists scratches well. Four corner prongs or a bezel protect the corners.
Is moissanite a type of diamond?
No. Moissanite is silicon carbide, a separate gemstone with its own optical properties, including more fire than diamond.
Can I get a custom cushion ring?
Yes. Ivevar makes custom rings, so you can choose the ratio, faceting style, setting, metal and band. A virtual appointment helps you see options first.
Which is better for cushion moissanite: white or yellow gold?
White gold keeps a colorless cushion looking as icy as possible. Yellow gold adds warmth and suits the cut's vintage character. Both look beautiful; choose the metal you will enjoy wearing every day.
The Bottom Line
Cushion moissanite offers romantic shape and bold fire. Choose your ratio, pick a setting style and enjoy a ring with timeless charm. Compare stones by millimeter size rather than weight, decide between chunky and crushed ice faceting by watching a video, and pick a band that sits flush with your setting. Those few steps make the difference between a good cushion ring and one you love for a lifetime.
