Oval Cut Lab Grown Diamond Engagement Rings

Oval Lab Grown Diamond Engagement Rings and the Cost of the Center Stone

A buyer who has a figure in mind usually wants to know how much of it the diamond will take before looking at settings, and on a lab grown oval it takes most of it. This page's 640 or more oval lab grown diamond engagement ring designs each hold a center stone drawn from the 187,087 lab ovals we had in stock on October 17, 2026. Of those, 156,334 can be viewed on 360 HD video. Once the current savings are applied the least expensive lab oval is $130. In the 0.90 to 1.10 carat band, the weight these designs are pictured with, the lowest price is $370 and the median is $652. With a 1.16 carat lab oval in place, the Linda comfort fit solitaire comes to $1,000, the Bellora hidden halo to $1,780 and the Vivian solitaire to $1,330, all three in 14K white gold and all three with the stone included. We refresh these numbers regularly from live inventory.

An oval shows more surface face up than a round of the same weight and draws the finger out longer, two points in favor of a lab grown oval engagement ring. Its two drawbacks, a bow tie across the middle and the premium a clean, well cut stone commands, are manageable in lab grown because the inventory is deep enough that you can afford to be choosy. Since the diamond sets most of the ring price, the next table breaks it out by weight.

What a Lab Grown Oval Center Costs at Each Weight

If you know roughly what weight you want, this table tells you what that band costs. All 187,087 lab ovals in our inventory fall into one of its rows, so the counts add up to that total, and the fullest row is 1.50 to 1.89 ct with 33,265 stones. Reading down the medians, a stone between 0.90 and 1.10 carats sits at $652 while one between 1.90 and 2.10 sits at $1,775 and one between 2.90 and 3.10 at $2,696. A finished ring costs the setting plus whichever stone you put in it, and if you change the stone the total changes to match. Where a band has a ring page of its own, the row links to it.

How High to Go on Color and Clarity in an Oval

A cautious buyer often asks whether a higher color grade is worth paying for on an oval, and in lab grown the premium is small. Within the 0.90 to 1.10 carat band, 98 percent of the lab ovals on the color ladder already grade D to F. Holding clarity at VS2 or better, a D color stone starts at $450 where a G starts at $370. Clarity behaves the same way once color is held at D to F, with VS1 opening at $415 and VVS2 at $470. For a lab grown oval engagement ring we would point you to D to F with VS1 or better, and then put what you did not spend on grade toward a heavier stone or the setting.

Lowest price by color grade, clarity held at VS2 or better (24,304 lab ovals), and by clarity grade, color held at D to F (23,962), all 0.90 to 1.10 ct

The Same Ring with a Natural Oval

Before you settle on lab grown, price the identical ring with a natural oval, because it is a different budget. For a one carat G color VS1 oval the starting price is $430 lab grown and $1,640 natural. Across the one carat band the medians are $652 for lab and $2,297 for natural. What you get for the extra money with a natural stone is scarcity and usually a GIA report, since 64,775 of the 70,123 natural ovals we stock carry one. With a lab stone the same outlay buys more size or grade. Our oval natural diamond engagement rings page prices these same designs with a natural center, and the oval diamonds grid lists both origins.

Which Setting Flatters an Oval

After the stone, the usual worry is whether the setting will hide the shape, and on an oval lab grown engagement ring the prongs decide that. Four prongs at the compass points leave the outline uncluttered, and past two carats a six prong head gives a lab oval extra hold. A hidden halo suits the shape because it adds brightness from the side without widening the outline. An east west mount, stone turned across the finger, is a newer look that lab pricing makes affordable at size. Prongs belong on the curve of the stone and not on its tips, where they make the stone look shorter.

For a sense of scale on the hand, a one carat lab oval runs about 7.5 by 5.5 mm, close to the stone size the oval lab grown diamond engagement ring designs here are pictured with in 14K white gold. Every design can also be ordered in yellow gold, rose gold or platinum, and the page redraws it with the stone you selected sitting in the head. Two scores sit beside each diamond in the picker. The AI price score measures the stone against similar lab ovals currently in stock and flags one that costs more than its peers, while the quality score out of 18 combines cut, color and clarity in one number. If you would rather have a person weigh in, our gemologists take no commission, answer by chat or phone, and will go over two or three oval finalists with you on video.

Today's Complete Ring Prices for an Oval Lab Grown Diamond Engagement Ring

When you see a price on the design grid, it already includes a center stone, today a 1.16 carat lab oval in 14K white gold. The amounts in the table below are what you would pay for a whole oval lab grown diamond engagement ring with that diamond, and not for an empty mounting. Among the first designs shown they range from $1,000 for the Linda comfort fit solitaire up to $1,780 for the Bellora hidden halo. The whole difference is the setting, since a plain comfort fit solitaire costs the least and a pavé or hidden halo design the most. Pick any other lab oval from the 187,087 in stock and each oval lab grown diamond engagement ring on the grid is repriced around the stone you chose.

How Rare Carat Handles Your Oval Lab Grown Diamond Ring Order

Before paying this much to a jeweler online, it is fair to ask who you are buying from. On every order the answer is Rare Carat itself, as the retailer and the merchant of record, with a stock of more than 2 million diamonds, natural and lab grown, available to set. With every design, resizing is free for the first year, and a lifetime manufacturing warranty covers the setting. After you order, the diamond goes through our New York facility, where staff put it under a microscope and check that its laser inscription matches the grading report before the ring is assembled. From there it ships free and insured, and returns are free for 30 days. At checkout you can split the cost through Affirm, Klarna, Afterpay, PayPal Pay Later or Katapult. Our customers rate us 5 out of 5 on Google and on Trustpilot, where that score makes Rare Carat the highest rated jewelry brand in America.

The stone counts and prices above cover every lab oval in Rare Carat inventory on October 17, 2026 that the diamond grid shows. The filters are Good cut or better, GIA, IGI or GCAL graded, with or without video, D to K color, and FL to SI2 clarity. That comes to 187,087 lab grown ovals, 156,334 of them with 360 HD video, alongside 70,123 natural ovals used for the comparison. Every stone price already has the current savings taken off, and the regular price shows struck through on the stone itself. A starting price means the lowest priced stone in that row, regardless of grade. Ring prices are those this page displayed on October 17, 2026, in 14K white gold and with the center stone identified, and the design count is the number of designs the page showed. The grade ladders use the 0.90 to 1.10 carat band only, which keeps weight fixed so that grade alone accounts for the change in price.
