Oval Cut Diamond Prices: Natural and Lab Grown, Every Carat

An oval at Rare Carat starts at $150 for a natural stone and $130 for a lab grown one, with the current savings applied, and those entry prices belong to small stones. What most people are pricing is a one carat oval: in the 0.90 to 1.10 carat band a natural oval starts at $625 with a median of $2,297, and a lab oval starts at $370 with a median of $652. The grid above holds 257,210 oval diamonds, 70,123 natural and 187,087 lab grown, which makes oval the second largest shape in our inventory after round. All figures come from Rare Carat inventory on October 17, 2026 and are refreshed regularly.

Ovals are priced per carat a little below rounds of the same grade, because an oval keeps more of the rough crystal, and they face up larger: a 1 carat oval runs about 7.5 by 5.5 mm against 6.5 mm for a round, which is the practical reason the shape has become the most searched fancy cut for engagement rings. The tables below separate the two origins, because a natural oval and a lab oval of the same weight sit in different price worlds.

Natural Oval Diamond Prices by Carat Weight

Natural oval prices climb in steps at the whole carat marks, and the steps get taller as the weight rises. The median natural oval is $2,297 between 0.90 and 1.10 carats, $13,501 between 1.90 and 2.10 carats and $32,674 between 2.90 and 3.10 carats, so the second carat costs more than the first and the third more than the second. Inventory thins the same way: 8,642 natural ovals sit in the one carat band, 2,195 in the two carat band and 796 in the three carat band. The rows in this table are the whole natural inventory on this page, split by weight.

Lab Grown Oval Diamond Prices by Carat Weight

Lab ovals are the volume end of this page: 187,087 stones, and the price curve is almost flat by natural standards. The median lab oval is $652 in the one carat band, $1,775 in the two carat band and $2,696 in the three carat band, so a shopper who moves from one carat to three carats in lab grown pays about 4 times the price for three times the weight, where a natural buyer pays about 14 times. The deepest stock is in the 1.50 to 1.89 ct band, which says where lab oval demand actually sits.

Length to Width Ratio: What the Oval Market Actually Buys

The ratio of length to width decides whether an oval reads as a soft circle or a slender ellipse, and it is the one specification no grading report grades. Across the 70,123 natural ovals here, 36,585 fall in the 1.30 to 1.39 range, the proportion most settings are built around; among lab ovals the center of the market is the 1.40 to 1.49 range with 126,287 stones. Slender ovals above 1.60 are scarce in both origins and tend to show a stronger bow tie, the dark band across the middle that appears when light leaks through the pavilion. Our advice is to pick the ratio with the setting in mind, 1.30 to 1.40 for a classic solitaire and 1.40 to 1.50 for east west or halo designs, and then use the 360 HD video to check the bow tie in motion rather than in a still photo.

Color and Clarity in an Oval Cut Diamond

An oval's brilliant faceting hides inclusions well, so clarity is the grade to economize on, and its pointed ends concentrate color, so color is the grade to protect. Holding clarity at VS2 in one carat natural ovals, G starts at $1,505, H at $1,380 and I at $885; D opens at $1,555. Holding color at G to H, SI1 starts at $1,030, VS2 at $1,380 and VS1 at $1,390. The combination most of our gemologists would point a natural oval buyer toward is G or H color in VS2 or SI1 clarity, with the inclusion checked on video and away from the center of the table.

Lab ovals come out of the growth process mostly colorless, so the color ladder barely moves: one carat lab ovals with VS2 or better clarity start at $450 in D and $370 in G, and 16,430 of the 24,304 stones on that ladder are D color. Clarity sets the lab price instead: among D to F lab ovals, VS1 starts at $415, VVS2 at $470 and VVS1 at $535.

Natural vs Lab Grown Oval at the Same Grade

Take a one carat G color VS1 oval: natural starts at $1,640 here with a median of $3,234, and the lab grown stone of the same grade starts at $430. For E color VVS2 the natural opens at $2,005 and the lab stone at $505. Both are ovals with the same optics; the natural one carries scarcity and a GIA report (64,775 of the natural ovals here are GIA graded), the lab one carries size for the money. If the decision is open, our 1 carat oval cut diamonds and 1 carat oval cut lab grown diamonds pages put the two side by side at the weight most people buy.

How to Buy an Oval Cut Diamond at Rare Carat

Start with the video. Most ovals on this page have 360 HD video, and the bow tie, the ratio and the tip color all show in motion. Use the Rare Carat Ideal filter to limit results to the proportions that return the most light, and read the AI price score on each stone, which compares it with similar ovals in stock and flags anything priced above its peers; the quality score out of 18 weighs cut, color and clarity together. Fluorescence is worth a glance on natural ovals (45,250 of the 70,123 have none), because strong blue fluorescence in a colorless stone can look hazy in daylight, while in a G to J stone it is harmless. Our gemologists will compare your finalists by chat or phone, and they earn no commission on which oval you choose.
