1 carat oval lab-grown engagement ring price

How much is a 1 carat oval lab-grown engagement ring?

Short answer: at Lavora Diamonds, a 1 carat oval lab-grown solitaire (F color, VS1 clarity) in 14K gold lands at the $2,000 complete-ring minimum. That covers the IGI-certified center, the setting and your custom 3D render.

By Lavora Diamonds, Provo, Utah. Updated October 2026.

On our ring price estimator, a 2.0ct F/VS1 oval solitaire in 14K white gold and a 1.5ct F/VS1 round solitaire in 14K yellow gold both model at the $2,000 Lavora minimum, so a 1 carat F/VS1 oval lands there too. A $2,000 budget at 1 carat leaves room to upgrade the color grade, add a hidden halo or size up the stone. A 2 carat E–F/VVS2 oval solitaire in 14K yellow gold is $2,175–$2,425. Your exact price comes with your 3D render. Complete engagement rings have a $2,000 minimum.

How big is a 1 carat oval?

An oval is an elongated brilliant cut. It spreads its weight along its length, so it faces up longer than a round of the same carat weight. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
1ct oval	about 8.0–8.7 mm long, 5.5–5.8 mm wide
1.5ct oval	about 9.1–9.6 mm long, 6.4–6.7 mm wide
1ct round (for comparison)	about 6.4–6.6 mm across

A 1 carat oval is about two millimeters longer than a 1 carat round is wide. Compare millimeters, not just carats, and check the length on your 3D render.

Buying tips

• Clarity: VS1+. Oval faceting hides small inclusions well, and VS1 is our floor.
• Ratio: most 1 carat ovals in our supplier feed run about 1.39 to 1.54 length-to-width. Lower reads fuller, higher reads slimmer.
• Bow-tie: many ovals show a darker bow-tie across the middle. It is not on the certificate, so ask us to show you the stone before production.
• Size up: at the $2,000 minimum, compare with 1.5 carat oval prices and 2 carat oval cost.
