An oval engagement ring holds an oval brilliant, a round brilliant's 58 facets stretched into an ellipse, and it is the most popular shape after the round: The Knot's 2023 study, as GIA reports it, put ovals on 23 percent of the rings bought that year. The reasons are practical. An oval shows more face than a round of the same weight (7 to 12 percent more in our picker on October 2, 2026), its length runs up the finger and makes the hand look longer, it has no points to chip, and it sparkles like a round. The decisions that matter are the length-to-width ratio (1.35 to 1.50 is where nearly every stone we sell sits), the bow-tie (the shadow across the middle that every oval has to some degree and only the video shows), and the setting, which on an oval means where the four prongs sit. Clairamor makes 45 oval settings, from the $950 solitaire to the $2,400 vintage inspired band, and on October 2, 2026 a lab-grown oval of D to G color and IF to VS2 clarity started at $720 for 1 carat, $1,454 for 2 and $1,633 for 3. This guide covers all of it, with the numbers from our own inventory.
Oval engagement rings at a glance
| The stone | An oval brilliant: 57 or 58 facets in the round brilliant's pattern, on an elliptical outline; the report reads Oval Brilliant |
| Length-to-width ratio | 1.30 to 1.50 is the classic range; the 300 least expensive 1 to 2.2 carat ovals in our picker ran 1.37 to 1.59 with a median of 1.44 |
| Size at 2 carats | About 10.3 by 7.1 mm, against 8.1 mm across for a round, 9.1 by 6.8 for a cushion, 8.8 by 6.1 for an emerald cut |
| Bow-tie | Present to some degree in every oval; faint and moving in a well-cut stone, a fixed dark band in a poor one; judge it from the video |
| Durability | No points or corners to chip; the most robust of the elongated shapes along with the cushion |
| Prongs | Four, at the shoulders of the stone, on our solitaire and cathedral heads; tulip petals, a bezel or a half bezel on the other designs |
| Color and clarity | A brilliant cut hides both: VS2 is clean to the eye, G reads white in any metal; D to F for white metal above 2 carats |

What an oval diamond is
An oval is a round brilliant that has been given a longer axis. The modern oval brilliant was created in 1957 by the diamond cutter Lazare Kaplan, who took the 58-facet pattern of the round and worked it onto an elliptical outline, so the stone kept the round's brilliance and gained length. On a grading report the shape and cutting style line reads Oval Brilliant, and the facet count is 57 or 58, with eight bezel facets on the crown and eight main facets on the pavilion, the same architecture as a round. That is why an oval sparkles like a round rather than like a step-cut emerald: the same facets are doing the same work, just over a longer stone. Our guide to elongated shapes sets the oval beside the other long cuts; this one is about the oval alone.
Its rise is recent and steep. For most of the twentieth century the oval was a niche shape next to the round and the princess; then lab-grown diamonds made two- and three-carat stones affordable, and a shape that shows more face for the weight and lengthens the finger became the obvious way to spend that size. On our own site the oval is the shape every one of our 45 designs is rendered in, and the oval versions of the tulip, bezel and cathedral settings are among the most searched-for rings we make.
Length-to-width ratio: how long should an oval be?
The ratio is the stone's length divided by its width, and it decides whether an oval reads as a soft round or a long ellipse. GIA puts 1.30 to 1.40 at the gently elongated end and 1.40 to 1.50 as the most popular range, with stones above 1.50 rare because they are impractical to cut from most rough. Our inventory agrees: on October 2, 2026 the 300 least expensive ovals of 1 to 2.2 carats in our picker ran from 1.37 to 1.59, with a median of 1.44, 172 of them between 1.35 and 1.45, 126 between 1.45 and 1.55, and only two above 1.55. If you want a short, rounded oval below 1.35 you will have to look hard for it; if you want a long one above 1.55, the same.

Outlines drawn to the same area, so the only thing that changes is how the stone spends it. Length runs up the finger; width is what the prongs have to hold.
What the number does on the hand: a 1.35 oval is forgiving, with full shoulders and a soft outline that suits a short finger and a wide band; a 1.45 is the shape most people picture when they say oval, long enough to lengthen the finger without looking stretched; a 1.55 is a noticeably long stone that flatters a long finger and a slim band, and it starts to show the bow-tie more. Compare stones by their millimeters rather than their carats, because two 2-carat ovals at 1.38 and 1.52 are visibly different rings. Two more things to check on the outline, both of which GIA flags: the shoulders should be evenly rounded, since flat shoulders make the stone read like a marquise and bulging ones make it read like a pill, and the two ends should mirror each other. Symmetry graded Excellent or Very Good on the report covers most of this; the face-up image covers the rest.
The bow-tie
Every elongated brilliant can show a darker band across its middle, and the oval shows it most often because the oval is cut most often. The band is a shadow: when you look straight down at the stone, the pavilion facets under the center reflect the light that is blocked by your own head and shoulders, so a bow-tie shaped patch goes dark, and GIA's guide says plainly that some degree of bow-tie is always present. The question is not whether an oval has one but how strong it is and whether it moves. In a well-cut stone the band is faint and flickers in and out as the hand turns, and most people never notice it; in a poorly cut one it is a fixed dark stripe that no setting hides.
No grading report records it, so it is the one thing you judge from the video in our picker, which every stone has. Turn the stone slowly in the video and watch the middle: a shadow that comes and goes is fine, one that stays is not. Proportions give a hint before you look. The ovals in our picker on October 2, 2026 ran from 55 to 68 percent depth with a median of 62, and tables from 54 to 68 percent with a median of 60; stones toward the deep end of that range and above 1.50 in ratio are where the stronger bow-ties live, and a shallow stone (the least expensive 1 carat that day was 8.36 by 5.40 mm at 56.7 percent depth) can look big for its weight and still have a soft one. Our marquise guide covers the same effect in the shape that shows it second most.
How big an oval looks: size by carat
An oval looks bigger than a round of the same weight for two reasons. It has more face-up area, because its outline is longer than it is wide and a little less of its weight sits in the pavilion: in our picker on October 2, 2026 the least expensive ovals at 1, 2 and 3 carats measured 8.4 by 5.4, 10.3 by 7.1 and 11.9 by 8.1 mm, which is 7 to 12 percent more area than the 6.5, 8.1 and 9.3 mm rounds of the same weight that day. And its length runs up the finger, which is where the eye reads size, so the extra millimeters count twice. The table gives the least expensive oval at each weight in our picker that day, D to G color, IF to VS2 clarity, with its measurements; our carat size chart does the same for every shape, and the size comparison simulator draws them on a hand.
| Carats | Oval in our picker | Ratio | Price | With our 14k solitaire ($950) |
|---|---|---|---|---|
| 0.5 | 0.56 ct, 6.6 x 4.5 mm | 1.47 | $381 | $1,331 |
| 1 | 1.00 ct, 8.4 x 5.4 mm | 1.55 | $720 | $1,670 |
| 1.5 | 1.50 ct, 9.0 x 6.6 mm | 1.38 | $878 | $1,828 |
| 2 | 2.02 ct, 10.3 x 7.1 mm | 1.47 | $1,454 | $2,404 |
| 2.5 | 2.53 ct, 11.2 x 7.6 mm | 1.47 | $1,466 | $2,416 |
| 3 | 3.03 ct, 11.9 x 8.1 mm | 1.47 | $1,633 | $2,583 |
| 4 | 4.16 ct, 12.9 x 8.9 mm | 1.45 | $2,334 | $3,284 |
| 5 | 5.00 ct, 13.9 x 9.6 mm | 1.44 | $2,673 | $3,623 |
| 7 | 7.14 ct, 15.8 x 10.9 mm | 1.45 | $3,674 | $4,624 |
| 10 | 10.02 ct, 17.7 x 12.3 mm | 1.44 | $4,870 | $5,820 |
Read the length column against something you know: a 2 carat oval at 10.3 mm is more than half the diameter of a dime, a 3 carat at 11.9 mm is two-thirds of one, and the 18 carat oval that was the largest in the picker that day, at 21.3 by 13.8 mm and $20,486, is longer than a dime is wide. Supply is deep in every size: more than 1,600 ovals between 1 and 3 carats and more than 720 at 3 carats and up were listed that day, so the ratio and the look you want are available at every weight.
Oval vs round, cushion, pear, marquise and emerald cut
The oval is the shape people compare everything else to, so here is everything else at 2 carats, the least expensive stone of each shape in our picker on October 2, 2026, D to G color, IF to VS2 clarity, with the measurements that decide how it looks on the hand.
| Shape, 2 ct | Size | From | Against the oval |
|---|---|---|---|
| Oval | 10.3 x 7.1 mm | $1,454 | The reference: long, bright, no points |
| Round | 8.1 mm across | $1,155 | The brightest cut and the cheapest at 2 carats that day; shows about a tenth less face and no length |
| Elongated cushion | 9.1 x 6.8 mm | $1,104 | Softer corners, a more vintage character and a deeper cut, so a shorter stone for the weight |
| Pear | 11.3 x 7.3 mm | $1,288 | An oval with one point: longer, with a tip to protect and a direction on the finger |
| Marquise | 12.7 x 6.8 mm | $1,498 | The longest of all, with two points, a stronger bow-tie and six prongs on our heads |
| Moval | about 11.8 x 6.6 mm | see the guide | An oval with softly pointed ends, longer at 1.7 to 2.0, a quarter to a third dearer for the weight |
| Emerald cut | 8.8 x 6.1 mm | $1,139 | A step cut: calm flashes instead of sparkle, shows color and inclusions, no bow-tie |
| Radiant | 9.1 x 6.3 mm | $1,096 | The oval's sparkle on a clipped rectangle; crisper, more modern, corners to cover |
Oval or round is the comparison most people are actually making, and it comes down to this: the round is a little brighter and a little cheaper at every weight, the oval shows more stone and lengthens the finger, and the round has no bow-tie to check. Oval or cushion is about edges and era, the oval's smooth outline against the cushion's softened corners and antique feel; the elongated cushion guide goes through it. Oval or pear is about the point, which gives the pear a direction on the finger and a tip to protect. Our which shape looks biggest page ranks all of them by face-up area.
Color and clarity for an oval
An oval is kind to both grades. Its brilliant facets break light into many small flashes that hide inclusions, so a VS2 is clean to the naked eye at any size we sell, and VS1 or VS2 is where the money should stop; every stone in our picker is IF to VS2, so there is nothing below that to avoid. Color shows a little more than in a round, because the ends of an oval are thinner than its middle and light makes a longer trip through a long stone, so a G oval can show a trace of warmth at its tips in platinum above 2 carats where a G round would not. The practical rule from our color scale guide holds: G reads white in yellow or rose gold at any size and in white metal under 2 carats, D to F in white metal above that; and since in lab-grown a D costs little more than a G, there is rarely a reason to argue about it. Our VS clarity and VVS1 guides cover the clarity side.
Settings for an oval
An oval has no points to protect, so every setting works, and the choice is about how much of the outline you want to see and how the ring sits. On our solitaire ($950) and cathedral ($1,000) heads the stone is held by four prongs at its shoulders, the four points where the curve of the outline is tightest, which leaves both long sides and both ends open and shows the shape in full; six prongs are the round's arrangement and are not needed on an oval. The tulip designs ($1,000 to $2,250) replace the claws with petals that cup the stone from below, and they are the oval settings our customers search for most. The hidden halo ($1,050) sets a ring of small diamonds into the gallery rail under the stone, where it shows from the side and braces the prongs without changing the outline from above; a classic halo around an oval tends to make it read rounder, which is the one thing most oval buyers do not want.
The full bezel ($950) follows the ellipse exactly and is the choice for a hand that works, and the half bezel ($950) covers the two ends and leaves the long sides open, which on an oval is the best of both. East-west, with the stone set across the finger instead of along it, suits the oval better than any other shape: the east-west half bezel ($950), east-west cathedral ($1,000) and east-west bypass ($1,500) all turn a 1.45 oval into a bar of light that sits low and reads wide. Three stone designs flank the oval with crescents ($1,350), pear-shaped sides ($1,400) or tapered baguettes ($2,200), and the low profile designs ($950 to $1,650) drop the whole head toward the finger. The table has every oval design we make, with prices before the stone.
Setting prices in 14k, 18k and platinum from our catalog on October 2, 2026, before the diamond; every design also comes in 14k and 18k yellow, rose and two-tone gold. The oval collection holds all 45, with sub-collections for solitaires, bezels, cathedrals, hidden halos, tulips, low profile, pavé bands, three stone, wide bands and engraved designs.
Oval engagement rings with a wedding band
The oval's overhang is modest, so it pairs more easily than the long pointed shapes. On the solitaire, the flat band and every bezel the head sits on a basket above the band, and a straight wedding band slides underneath and sits flush. On the cathedral and hidden halo designs the arches or the rail rise to meet the stone, so a straight band usually leaves a small gap at the top unless it is curved or notched; on the low profile designs the stone sits at the band, so a straight band meets its overhang and a curved one closes the gap. An east-west oval wants its band chosen with it. We make curved and notched bands to order to fit any of our settings, and our guide to matching a wedding band goes through the pairings.
What a lab-grown oval costs
The table above gave the least expensive oval at each weight; the pattern behind it is that lab-grown oval prices step up with carats and barely move with color. On October 2, 2026 a 2 carat oval of VS1 or VS2 clarity in our picker cost $1,505 at D, $1,468 at E and $1,556 at F, and a 3 carat $2,248, $1,981 and $2,121, so the letter is not where the money goes; cut quality and clarity are, and a 2 carat oval ran $1,476 at VS2 and $2,375 at IF that day. Against the other shapes the oval sits in the middle: at 2 carats it cost $1,454 to the round's $1,155, the emerald cut's $1,139 and the cushion's $1,104, and less than the marquise at $1,498. With the setting, a 14k solitaire with the 1 carat oval is $1,670, with the 2 carat $2,404 and with the 3 carat $2,583; the lab-grown pricing guide explains the levers and the price calculator estimates any combination.
How to pick a good oval
Six checks, all of which our picker lets you make from the report, the measurements and the video. First, the ratio: divide length by width and aim for 1.38 to 1.50 unless you want a short, round-shouldered oval or a long one, and know that below 1.35 and above 1.55 the choice is thin. Second, the shoulders: the four should match, neither flat nor bulging, and the two ends should mirror each other; Excellent or Very Good symmetry on the report is the first filter and the face-up photo the second. Third, the bow-tie: turn the stone in the video and watch the middle for a shadow that stays. Fourth, the proportions: depth under about 65 percent and a table of 55 to 62 percent keep the weight where you can see it; the stones in our picker ran 55 to 68 and 54 to 68. Fifth, the grades: VS1 or VS2, G in gold or under 2 carats in white metal, D to F above that in platinum or white gold. Sixth, the measurements: compare your finalists by millimeters and ratio, not by carat weight, then put them on a hand in the simulator. The 4Cs guide covers the grades behind the report, and the certification guide shows how to read one.
Where Clairamor fits
Every oval ring we make is a setting from the 45 above plus an oval you choose from our picker, which listed more than 1,600 ovals between 1 and 3 carats and more than 720 above 3 carats on October 2, 2026, every one lab-grown, D to G color, IF to VS2 clarity, with an IGI, GIA or HRD report, the measurements and ratio, a face-up photo and a video. The setting price is the setting without the center stone, so the $950 solitaire with the 2 carat oval at $1,454 is a $2,404 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.

Frequently asked questions
What is an oval cut diamond?
A brilliant-cut diamond with an elliptical outline: the round brilliant's 57 or 58 facets worked onto a stone that is longer than it is wide, usually 1.35 to 1.50 times. The modern oval was created by Lazare Kaplan in 1957. It sparkles like a round, shows more face for its weight and has no points to chip.
Are oval diamonds more expensive than round?
Not in lab-grown; they are a little more. In Clairamor's picker on October 2, 2026 the least expensive 2 carat oval was $1,454 against $1,155 for a round, and at 1 carat $720 against $656. In mined diamonds the oval is usually cheaper than the round because less rough is lost cutting it.
What is the best length-to-width ratio for an oval?
1.35 to 1.50 for most hands and settings, with 1.40 to 1.50 the most popular range. Below 1.35 the stone reads as a soft round; above 1.55 it reads long and shows the bow-tie more, and few are cut that way. The median in Clairamor's picker on October 2, 2026 was 1.44.
Do all oval diamonds have a bow-tie?
To some degree, yes; GIA says some bow-tie is always present. It is a shadow across the middle caused by the viewer's own head blocking light. In a well-cut oval it is faint and moves as the hand turns; in a poorly cut one it is a fixed dark band. No report records it, so judge it from the video.
Does an oval look bigger than a round?
Yes. At the same weight an oval has more face-up area, 7 to 12 percent more in Clairamor's picker on October 2, 2026 (a 2 carat oval at 10.3 by 7.1 mm against an 8.1 mm round), and its length runs up the finger, where the eye reads size.
How much is a 2 carat oval diamond?
In Clairamor's picker on October 2, 2026, a lab-grown 2 carat oval of D to G color and IF to VS2 clarity started at $1,454, measuring 10.3 by 7.1 mm; a 1.5 carat started at $878 and a 3 carat at $1,633. With the 14k solitaire at $950 the 2 carat ring comes to $2,404.
What setting is best for an oval diamond?
Four prongs at the shoulders, as on a solitaire, tulip or cathedral head, show the whole outline and are the classic choice. A half bezel covers the ends and leaves the sides open; a full bezel suits a hand that works; a hidden halo adds sparkle from the side without rounding the shape; east-west suits the oval better than any other cut.
Four prongs or six for an oval?
Four. They sit at the shoulders of the stone, where the curve is tightest, and leave the ends and the long sides open. Six prongs are the round's arrangement; on an oval they crowd the outline and cover more stone than they protect. Clairamor's oval solitaire and cathedral heads are made with four.
What color and clarity should an oval diamond be?
VS1 or VS2 clarity, because the brilliant facets hide inclusions, and G color in yellow or rose gold or under 2 carats in white metal, D to F in white metal above that, since an oval shows a trace of warmth at its ends sooner than a round. Every stone in Clairamor's picker is D to G and IF to VS2.
Oval or cushion: which should I choose?
The oval for a smooth outline, more length per carat and a brighter, more modern look; the cushion for softened corners, a vintage character and a slightly lower price. At 2 carats in Clairamor's picker on October 2, 2026 the oval measured 10.3 by 7.1 mm at $1,454 and the elongated cushion 9.1 by 6.8 mm at $1,104.
Will a straight wedding band sit flush with an oval engagement ring?
On a solitaire, flat band or bezel, yes, because the head sits on a basket above the band. On a cathedral or hidden halo a straight band usually leaves a small gap unless it is curved or notched, and on a low profile design it meets the stone's overhang. Clairamor makes curved and notched bands to order.
