Cushion Cut Engagement Rings: Square vs Elongated, Sparkle, Settings, Sizes and Prices

By Cameron Malakan, owner of Clairamor and third-generation jeweler · Published October 6, 2026

A cushion cut engagement ring holds a pillow: a brilliant-cut diamond that is square or softly rectangular, with rounded corners and gently curved sides, descended from the old mine cut that was the diamond of the 1700s and 1800s and that came back into every conversation when Travis Kelce proposed to Taylor Swift with one. Two choices decide how a cushion looks, and most guides skip both. The first is the outline: square, at a length-to-width ratio up to about 1.10, or elongated, from about 1.15 up; Clairamor sets elongated cushions only, and our picker lists cushions at a ratio of 1.20 and up, 1,320 of them between 1 and 3 carats on October 6, 2026. The second is the facets: "chunky", the antique pattern of big clear flashes, or "crushed ice", the modern shimmer of hundreds of small ones. A cushion is also the most forgiving of the fancy shapes to wear, because it has no points, and the one that most reliably looks a little smaller than a round of the same weight, because it is cut deep. Clairamor makes 40 cushion settings, from the $950 solitaire and bezel to the $2,400 vintage inspired band, and on October 6, 2026 a lab-grown elongated cushion of D to G color and IF to VS2 clarity started at $724 for 1 carat, $946 for 1.5, $1,216 for 2 and $1,981 for 3, within $25 of a round at 1.5 and 2 carats. This guide covers the two choices, how big each carat really looks in millimeters, the cushion against the round, princess, radiant and oval, color and clarity, every setting we make with its price, and what the whole ring costs, with the numbers from our own inventory.

Cushion cut engagement rings at a glance

What a cushion cut diamond is

GIA describes the modern cushion as square or squarish-rectangular, with curved sides and either rounded or pointed corners, and calls it one of the oldest diamond shapes and cutting styles there is. The shape comes from the old mine cut, which dates to the 1700s and was the most common diamond cut until the late 1800s: a squarish stone with a high crown, a small table, a deep pavilion and a large culet, the flat facet at the very bottom that you can see through the table as a small dark window. The old mine cut has 58 facets, as a modern round brilliant does, but they are bigger and chunkier, with a softer, less defined pattern of light and dark, so an antique stone throws less white brilliance than a modern cut and more fire, the colored flashes. The modern cushion keeps the pillow outline and reworks the facets for brightness, and that is where the two kinds of cushion come from. A Cushion Brilliant, the name you will see on an IGI or GIA report, has four or eight mains, the kite-shaped facets that run from the girdle to the culet, and reads like a softened round; a Cushion Modified Brilliant adds extra facets to the crown or pavilion, and reads like crushed ice. Either way the corners are rounded, the sides bow out a little, and the stone sits on the finger like a pillow, which is where the name comes from and why the trade sometimes still calls it a pillow cut.

The cushion has a long list of famous stones behind it, which is part of why it reads as old money: the Hope Diamond and the Cullinan II are cushions, and the Archduke Joseph, a 76.02 carat cushion, sold at auction for $21.5 million in 2012. A survey by The Knot that GIA cites had it third among engagement ring shapes as far back as 2013, before the elongated version existed in any quantity. What changed the conversation in 2025 was the ring Travis Kelce proposed to Taylor Swift with, announced on August 26 of that year: an elongated old mine cut diamond, the cushion's ancestor, set in a hand-engraved yellow gold band by Kindred Lubeck of Artifex Fine Jewelry, with a weight that was estimated at eight to ten carats and never confirmed. It is the reason the antique cushion and the old mine cut are in so many searches now, and the reason the chunky cushion, the modern stone that looks most like an old mine cut, is the one people ask us about by name.

Square or elongated: the first choice

The ratio is the stone's length divided by its width, from the measurements on the report, and it is the first thing to settle because it changes what the ring is. Up to about 1.05 the cushion is square, the classic pillow, and it reads on the hand like a softened square or a round with corners: it sits centered on the finger, it carries a halo or a vintage setting the way the stones in old rings did, and it shows the chunky facet pattern best, because a square outline keeps the facets symmetrical. From 1.05 to 1.10 it is still square to the eye but a shade longer, which is the proportion a lot of antique cushions were cut to. From about 1.15 the stone starts to read as a rectangle, and 1.20 to 1.35 is the elongated cushion proper: it runs up the finger and lengthens it, it shows more face for the weight, and it reads as modern, which is why it has become one of the most searched-for shapes in engagement rings. Above 1.40 the stone begins to look like a radiant with rounded corners, and stones that long are scarce. Clairamor sets elongated cushions only. Our picker lists cushions from a ratio of 1.20 up, and on October 6, 2026 it held 1,320 of them between 1 and 3 carats: 376 between 1.20 and 1.25, 586 between 1.25 and 1.35 and 359 longer still, so the classic range is where the largest share of the supply sits. The wider lab-grown feed our picker draws from holds nearly as many square cushions as elongated ones at those weights, so the square is far from gone in the market; it is simply not the cushion we make, and if a square one is what you want, ask us. Our elongated cushion guide goes deep on the long version, its ratios, its sizes and its price against the oval, radiant and emerald cut; this guide covers the cushion as a whole, square and long, so that the choice is an informed one. Every cushion setting we make is made to the stone you choose, because a cushion's corners and ratio vary from stone to stone and the prongs or the bezel are cut to them.

Chunky or crushed ice: the second choice

This decides how the stone behaves in light, and it is independent of the ratio: a square cushion and an elongated one can each be cut either way. A chunky cushion, the Cushion Brilliant on the report, has a pavilion like a round's, with facets that meet at the center in a clear pattern, and it returns light in large, separate flashes that you can see from across a table; jewelers also call it an antique cushion, because it is the modern stone that looks most like an old mine cut, and it is the look that the Swift ring put back in front of everyone. A crushed ice cushion, the Cushion Modified Brilliant, adds a row of facets to the pavilion, and the result is a mass of needle-fine flashes with no visible pattern, glittering and bright, which in a big stone under strong light looks a little like a mosaic. Most cushions on the market, and most lab-grown cushions, are crushed ice, because the extra facets make it easier to cut a stone, square or long, that stays bright from edge to edge; chunky cushions are scarcer and the antique-style ones carry a premium.

The report tells you which you are looking at, and so does the face-up image in the picker: a clear star of facets for chunky, a shimmer for crushed ice. Which to choose is taste. Crushed ice hides inclusions better than almost any cut and looks livelier in low light; chunky has more personality, shows its facets, hides less and looks more like an heirloom. Neither is the right one, but know which you are looking at before you fall for a photograph, because the two do not look alike on the hand even at the same weight, color and clarity.

How big a cushion looks: size by carat

Cushions are cut deep. The median cushion between 1 and 3 carats in our picker on October 6, 2026 had a depth of 67.3 percent of its width and a table of 62 percent, where the median round had 61.6 and 58, so more of a cushion's weight sits in the pavilion, under the girdle, where it adds nothing to the face. That is the whole of the "cushions look smaller" complaint, and it is true of the square cushion: a 1 carat square cushion measures about 5.8 by 5.7 mm against 6.4 mm for a round, and a 2 carat about 7.4 by 7.1 mm against 8.1, which is about five percent less face for the same weight. The elongated cushion, the one we sell, closes the gap by spreading the same face along the finger, so a 2 carat elongated cushion at 8.5 by 6.7 mm shows about the same area as the 2 carat round and reads larger, because the eye measures length. Neither is as big as an oval, which is the shape to choose if spread per carat is the point. The table gives the median measurements of 24 elongated cushions at each weight in our picker that day, with a square cushion of the same weight from the wider feed and the round beside them.

Three things follow from the table. A square cushion, if you are weighing one against ours, has to be bought a little heavier than a round to show the same face, since 1.5 carats of square cushion (6.7 mm) shows about what 1.2 carats of round does; an elongated cushion needs no such allowance. In height a cushion stands no taller than a round of the same weight and only a touch taller than an oval, about 4.5 mm deep at 2 carats against 5.0 for the round and 4.4 for the oval, so the "cushions sit high" worry is about proportion, not millimeters, and a bezel or a low profile setting settles it either way. Compare stones by their measurements on the report, never by carats alone, and put the finalists on a hand in our size simulator; our which shape looks biggest page ranks every shape by face per carat, and the carat size chart has every shape at every weight.

Cushion vs round, princess, radiant, oval and emerald cut

The comparisons people search for most, with the least expensive stone of each shape in our picker on October 6, 2026, D to G color and IF to VS2 clarity, at 1, 1.5, 2 and 3 carats. The elongated cushion that day was $724, $946, $1,216 and $1,981.

Cushion vs round

The round is the brightest cut there is, with a pattern of light and dark that every other brilliant is measured against; the cushion is softer, with less brilliance and, in a chunky stone, more fire. The round shows more face per carat, 6.4 mm against 5.8 for a square cushion at 1 carat. In price they are close: the round was $651 at 1 carat against the cushion's $724, $923 against $946 at 1.5, $1,204 against $1,216 at 2 and $1,799 against $1,981 at 3, so the cushion ran $12 to $25 over the round at the two most common weights and more at the ends, which is a far cry from mined diamonds, where the round has always carried a premium for the rough it wastes. Choose the round for maximum sparkle and the cushion for softness, a vintage character and a shape that takes a bezel and rose gold better; our solitaire guide covers the round on its classic head.

Cushion vs princess cut

The two squares. The princess is a square brilliant with four sharp corners, which are the four most vulnerable points a diamond can have and need V-shaped prongs; the cushion rounds them off, which is why it wears so much more easily and why antique rings used it. The princess shows a little less face, about 5.5 mm square at 1 carat against the cushion's 5.8, and sparkles in the round brilliant's way, in crisp flashes; the cushion sparkles its own way. We do not list princess cuts in our picker or make settings for them: on our shape menu the radiant is the square brilliant with clipped corners, and the elongated cushion the soft one, and between them they cover what a princess does with none of the chipping.

Cushion vs radiant cut

The most-searched cushion comparison, because the two are the brilliant rectangles. The radiant's corners are clipped straight, which reads sharper and more modern; the cushion's are rounded and read softer. The radiant's facets give big, crisp flashes; a crushed ice cushion's a fine shimmer, a chunky cushion's something in between. At 2 carats they measure close, 9.1 by 6.3 mm for the radiant against 8.5 by 6.7 for the elongated cushion, and the radiant was the cheaper stone at every weight, $659 against $724 at 1 carat, $801 against $946 at 1.5 and $1,096 against $1,216 at 2, and within $5 at 3. Our radiant cut guide covers the radiant on its own.

Cushion vs oval

The oval is the shape to choose for spread: a 2 carat oval measured 10.3 by 7.1 mm against 8.5 by 6.7 for the elongated cushion, and it lengthens the finger more than any cushion. The cushion has straighter sides, a more geometric and more vintage character, a milder bow-tie and a stone that sits a touch higher. The two trade places by weight: the oval was $720 against the cushion's $724 at 1 carat, $878 against $946 at 1.5, $1,454 against $1,216 at 2 and $1,870 against $1,981 at 3, which is the day's supply talking; across the sizes they sit within a few percent of each other. Our oval guide covers the oval's own ratios, its bow-tie and its settings.

Cushion vs emerald cut

Same family of outline in the elongated version, opposite kinds of light. The emerald cut is a step cut, calm and clear, with long flashes and no sparkle to speak of, and it shows inclusions and color; the cushion sparkles and hides both. The emerald cut was the least expensive shape in our picker at every weight, $640 against the cushion's $724 at 1 carat and $1,513 against $1,981 at 3. If you want the rectangle without the sparkle, the emerald cut; with it and softer corners, the cushion. Our elongated engagement rings guide puts every long shape side by side.

Cushion vs old mine cut

Not a comparison of two modern stones. The old mine cut is an antique cut, from the early 1700s to the late 1800s, with 58 facets like a modern round but a smaller table, a higher crown, a larger culet and short lower facets, which give it chunky facets, a softer pattern, less brilliance and more fire; the stones were cut by eye and by hand, and an antique one usually has a thin girdle that GIA advises protecting all the way round. The modern cushion is its heir, and the chunky cushion is the modern stone that comes closest to the look. Our picker lists modern cuts, so if a true old mine cut is what you want, ask us and we will search for one; a chunky cushion in a bezel or an engraved yellow gold band is the way most people get there.

Color, clarity and the bow-tie in a cushion

Cushions hold onto color more than rounds do, because their deep pavilions and rounded outlines bounce light around inside the stone, so a warm grade shows sooner in a cushion than in a round and sooner again in a square one, which has no long axis to spread the light along. Our D to G range keeps every stone white; G is a sound choice in yellow or rose gold, where the metal warms the stone anyway, and under 2 carats in any metal, and D to F is worth it in a large stone in white gold or platinum. The grades cost little in lab-grown. On October 6, 2026 the least expensive 2 carat cushion was a G at $1,216, an E $1,302, an F $1,328 and a D $1,341, a $125 spread from G to D and not even in order; at 3 carats the cheapest D, a long 1.67 stone, was $2,107 and the cheapest G, a 1.41, $2,744, which tells you that in lab-grown the cut and the ratio move the price more than a color grade does. Our color scale guide shows what each grade looks like against the next.

Clarity depends on which cushion you chose. A crushed ice cushion hides inclusions better than almost any other cut, because its hundreds of small facets break up anything inside the stone, so VS2 is clean to the eye at any size we sell. A chunky cushion, with its larger, clearer facets, is closer to a round and benefits from VS1 at 2 carats and up, where an inclusion under the table has a bigger window to show through, as our VS1 vs VS2 guide explains. Here too the grades are nearly free: the cheapest 2 carat cushion that day was a VVS2 at $1,216, a VS2 was $1,302, a VS1 $1,371, a VVS1 $1,491 and an IF $3,472, so the only clarity that costs real money is flawless. The bow-tie, the darker band across the middle of a long brilliant where the pavilion facets reflect the viewer, is mild in cushions, faint in most chunky stones and usually invisible in crushed ice, and only worth a careful look in the video above a ratio of 1.35. Every stone in our picker is D to G and IF to VS2 with its IGI or GIA report; our VVS1 and SI clarity guides explain where the lines fall.

Settings for a cushion: what we make

The rounded corners are the cushion's gift to the setter. There are no points to protect, so every setting we make comes in cushion, 40 designs and more than 350 rings in the cushion cut engagement rings collection across nine metals, and the prong heads hold the stone in four prongs on the corners, which show the most stone and keep the pillow outline clear. Two facts from our own traffic are worth knowing before you choose. The bezel cushion is the cushion collection people find us for most, by a wide margin, and it deserves it: the rim follows the soft rectangle exactly, protects the stone completely, lowers it, and reads as modern on an elongated stone and as antique on a square one. And the tulip hidden halo cushion is the single cushion ring people look at most on our site, because its petal prongs cup the corners and its rail of small diamonds under the stone adds sparkle where a deep cushion is seen from the side. Prices are the setting in 14k gold without the center stone.

A few notes on the choice. If you want the halo look, we do not stock the classic full halo, which blurs a cushion's outline and makes a square one read as a round; we quote it as a custom piece, and the hidden halo, which puts the small diamonds under the stone instead of around it, is what most people who ask for a halo end up with, at $1,050 against the $950 solitaire. If you want the antique look, which is where the cushion came from, the engraved and vintage-inspired designs in yellow gold are the ones, with a chunky cushion in them if you can find one you love; the art deco, with its channel of baguettes down each shoulder, is a 1920s look rather than an engraved one, and it is the cushion ring people search for by name. Rose gold suits the cushion better than almost any other shape, because the warm metal and the soft outline agree, and the rose gold cushion collection, 84 rings, is the cushion collection people find us for second most, after the bezel; a G color stone in rose gold reads as warm as the metal and no warmer. And whatever the design, the prongs or the bezel are made to the stone you choose, because a cushion's corners and ratio vary from stone to stone, and a head cut for a different cushion leaves gaps at the corners.

How a cushion wears

A cushion is the easiest fancy shape to live with. Its corners are rounded and thick, so there is no point to chip, which is the weakness of the pear, the marquise and the princess; GIA's one caution is that the corners can be vulnerable if the girdle is extremely thin, which is a question for antique stones more than modern ones, and its answer is a bezel. On our rings the four prongs sit on the corners, where the stone is strongest and the prongs are least in the way of the light. Height is the thing to decide with your eyes rather than your worries: a cushion is deep as a share of its width, but in millimeters it stands no taller than a round, so a 2 carat cushion on our solitaire sits about where a 2 carat round would, 6.5 mm above the finger on the classic head; the low profile designs drop that to about 5.9 on prongs and 4.9 in the low profile bezel, and the bezel and the hidden halo keep the deep pavilion from reading as a tower from the side. Crushed ice cushions stay bright when they are a little dirty, because their many small facets keep scattering light; chunky ones show grime sooner and reward a weekly brush. The routine is the same for every ring we make: warm water, a drop of dish soap and a soft toothbrush under the stone once a week, the prong check our care and cleaning guide describes, and the ring off for the gym, the garden and any work with tools or ropes.

Cushion cut engagement rings with a wedding band

The band question depends on the setting, not the stone. A straight wedding band sits flush against the solitaire, the flat band and the bezels, because the head stands on a basket above the band and the wedding band slides underneath; on a square cushion the pair reads as one piece, and on an elongated one the band tucks under the long side. The cathedral and the hidden halo designs usually leave a small gap at the top, since the band meets the arches or the gallery rail first, unless the band is curved or notched to it. The low profile designs put the stone at the band, so a straight band meets its overhang and leaves a small gap unless the band is curved, and the bypass half bezel and the east-west designs want a band made to them. We make curved and notched bands to order for any of our settings, and the pairing is easiest to settle before the engagement ring is made; our guide to matching a wedding band goes through the pairings for every design.

What a cushion cut engagement ring costs

Two numbers make the ring: the setting, $950 to $2,400 in 14k gold, and the stone, which you choose from our picker. The table gives the least expensive cushion at each weight in our picker on October 6, 2026, D to G color and IF to VS2 clarity, with its ratio, and the complete ring on the $950 solitaire or bezel. Our lab-grown diamond pricing guide explains why the setting is now the larger share of a 1 carat ring and the stone the larger share of a 3 carat one, and the price calculator estimates any combination of grades.

So, are cushion cut diamonds more expensive? Not by much, in lab-grown. The cushion was $73 over the round at 1 carat, $23 at 1.5, $12 at 2 and $182 at 3; the oval traded places with it by weight, the radiant was cheaper at every weight but 3 and the emerald cut at every weight, so the cushion sits in the middle of the pack with the round, and the gaps between shapes are a day's supply rather than a rule. In the wider lab-grown feed our picker draws from, square cushions ran $50 to $100 over elongated ones at 1 to 2 carats that day, because elongated rough is cut in quantity now, which is one more reason the elongated cushion is the one we sell; the antique-style chunky cushion is the one version that carries a premium, because it is scarce. The largest cushion in our picker that day was an 18.05 carat E VS1, 16.1 by 13.1 mm, at $16,150. And a reading of the table for the ring most people are deciding on: a 2 carat elongated cushion on the bezel was $2,166 complete, on the tulip hidden halo $2,266, on the three stone with half-moon sides $2,566 and on the art deco $3,066, all in 14k gold.

How to choose a cushion

Settle the ratio first. Our cushions start at 1.20, and 1.25 to 1.35 is where the largest share of them sit; hold a 1.20 and a 1.35 in the simulator at the carat you have in mind, because the shorter one reads as a softened square and the longer one as a clear rectangle, and the two make different rings on the same setting. Then the facets, chunky or crushed ice, from the cut name on the report and the face-up image; the antique look wants chunky, the modern one usually gets crushed ice, and the chunky stones are fewer, so search for them early. Then depth and table from the report: aim for a depth under 68 percent and a table between 58 and 66, which keeps the weight where you can see it, and remember the median cushion in our picker was 67.3 and 62. Then the face-up image and the video: even brightness edge to edge, no dark or glassy patches at the corners, a soft or absent bow-tie on a long stone, and symmetry, because GIA's test of a good cushion is that the opposing sides mirror each other and the eye reads a lopsided pillow at once. Then compare two or three finalists by millimeters, not carats. Then the setting: the bezel for a hand that works or a stone you want low and protected, the solitaire or the tulip to show the most stone, the hidden halo for sparkle from the side, the three stone with half-moon sides for width, an engraved band in yellow gold for the antique ring the cushion was born into. Then the metal, with rose gold the cushion's own pairing and a G color stone at home in it. Our settings guide puts every setting side by side, and our guide to the 4Cs covers the grades behind the report.

Where Clairamor fits

Every cushion ring we make is one of the 40 settings above plus a lab-grown elongated cushion you choose from our picker, chunky or crushed ice, D to G color and IF to VS2 clarity, with an IGI, GIA or HRD report, a face-up photo and a video; on October 6, 2026 the picker held 1,320 cushions between 1 and 3 carats and 1,608 at 3 carats and up, all at a ratio of 1.20 or more. The setting price is the setting without the stone, so the $950 bezel with the 2 carat elongated cushion at $1,216 is a $2,166 ring. Every ring carries a lifetime warranty against manufacturing defects, comes with an appraisal for insurance, and includes one complimentary resize within 100 days for clients in the USA. The prongs or the bezel are made to the cushion you choose, and the ring still comes off for the gym, the garden and any work with tools or ropes.

Frequently asked questions

What is a cushion cut diamond?

A brilliant-cut diamond with a square or softly rectangular outline, rounded corners and gently curved sides, named for the pillow it resembles. It is the modern heir to the old mine cut of the 1700s and 1800s. The report calls it a Cushion Brilliant, with large clear facets, or a Cushion Modified Brilliant, the crushed ice version with hundreds of small ones.

Are cushion cut diamonds more expensive?

Not by much, in lab-grown. On October 6, 2026 the least expensive D to G, IF to VS2 elongated cushion in our picker was $724 at 1 carat, $1,216 at 2 and $1,981 at 3, within $25 of a round at 1.5 and 2 carats and mid-pack among the shapes. Square cushions ran $50 to $100 over elongated ones in the wider feed; chunky antique-style stones carry a premium.

Do cushion cut diamonds look smaller than rounds?

A square cushion does, by about five percent of face: it is cut deeper, about 67 percent against 62 for a round, so a 1 carat square cushion measures about 5.8 mm against the round's 6.4 and a 2 carat 7.4 by 7.1 mm against 8.1. An elongated cushion, the kind we sell, spreads that face along the finger, 8.5 by 6.7 mm at 2 carats, and reads as large.

What is the difference between a cushion and an elongated cushion?

The ratio. A cushion with a length-to-width ratio up to about 1.10 is square, the classic pillow; from about 1.15 it reads as a rectangle and is called elongated, with 1.20 to 1.35 the usual range. Both are cushions and both come chunky or crushed ice. Clairamor sets elongated cushions only: our picker lists cushions from 1.20 up, 1,320 of them between 1 and 3 carats on October 6, 2026.

Cushion cut vs princess cut: which is better?

The princess is a square brilliant with four sharp corners that can chip and need V-prongs; the cushion rounds them off, which makes it the easier stone to wear. The princess shows slightly less face and sparkles in crisper flashes; the cushion more softly. We do not list princess cuts or make settings for them: the radiant is our square brilliant with clipped corners, the elongated cushion our soft rectangle.

Is a cushion cut good for an engagement ring?

One of the best shapes for one. It has no points to chip, it takes a bezel as well as prongs, it suits yellow and rose gold and antique settings better than any other shape, and in lab-grown it costs what a round does. The one trade-off is that a square cushion shows a little less face per carat than a round, which the elongated cushion gives back.

What are the disadvantages of a cushion cut diamond?

Three. It is cut deep, so a square cushion shows about five percent less face than a round of the same weight. It holds color more than a round, so a warm grade shows sooner, which our D to G range avoids. And its two facet styles look nothing alike, so a crushed ice stone bought from a photograph of a chunky one disappoints; read the report's cut name first.

What setting is best for a cushion cut diamond?

The bezel, if the stone will be worn hard or you want it low: the rim follows the pillow outline and protects it completely, and the bezel cushion is the cushion collection people find us for most. Four prongs on the corners, as on our solitaire and tulip designs, show the most stone; the hidden halo adds sparkle from the side; an engraved yellow gold band makes the antique ring.

Is Taylor Swift's engagement ring a cushion cut?

It is an old mine cut, the antique ancestor of the cushion: an elongated old mine brilliant cut diamond in a hand-engraved yellow gold band by Kindred Lubeck of Artifex Fine Jewelry, announced in August 2025, its weight estimated at eight to ten carats and never confirmed. The modern stone closest to the look is a chunky cushion, the Cushion Brilliant on a report, in an engraved yellow gold setting.

How much does a cushion cut engagement ring cost?

At Clairamor the setting is $950 to $2,400 in 14k gold and the cushion is priced on its own. On October 6, 2026 a 1 carat D to G, IF to VS2 elongated cushion was $724 in our picker, a 1.5 carat $946, a 2 carat $1,216 and a 3 carat $1,981, so a 2 carat cushion on the $950 bezel was $2,166 complete, $2,266 on the tulip hidden halo.

What ratio should a cushion cut diamond be?

Whichever outline you want. Up to about 1.05 is a true square, 1.05 to 1.10 a square that reads a shade long, as many antique cushions were cut, and 1.20 to 1.35 the classic elongated cushion that lengthens the finger; above 1.40 the stone looks like a radiant with rounded corners and is scarce. Our picker lists cushions from 1.20 up, and the largest share sit between 1.25 and 1.35.
