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

Short answer: at Lavora Diamonds, a 1 carat marquise lab-grown solitaire (D–E 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.

Our design-desk rates are per carat, not per shape, so a marquise prices like any other shape of the same size and grade on the desk; the exact stone you choose sets the final number. Our default center is D–E color with VS1+ clarity, quoted on the exact stone you choose. On our ring price estimator, a 1.5ct D–E/VS1+ round solitaire in 14K yellow gold and a 2.0ct D–E/VS1+ solitaire in 14K white gold both model at the $2,000 Lavora minimum, so a 1 carat marquise in the same grade lands there too. A $2,000 budget at 1 carat leaves room to add a hidden halo, choose 18K gold or size up the stone. A 2.5ct D–E/VS1+ marquise hidden halo in 14K yellow gold is $2,000–$2,300 on our ring price estimator. Your exact price comes with your 3D render. Complete engagement rings have a $2,000 minimum.

How big is a 1 carat marquise?

A marquise is a long, pointed brilliant cut. It spreads its weight along its length, so it faces up longer than any other shape 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 round (for comparison)	about 6.4–6.6 mm across
2ct marquise	about 12.7–13.9 mm long, 6.4–6.7 mm wide

A 1 carat marquise is shorter than the 2 carat marquise above, but its long outline still faces up longer than a 1 carat round is wide. We confirm the exact millimeters on the stone you choose before production, and you check the length on your 3D render.

Buying tips

• Clarity: VS1+. Marquise faceting hides small inclusions well, and VS1 is our floor.
• Bow-tie: most marquise stones show a darker band across the middle. It is not on the certificate, so ask us to show you the exact stone before production.
• Protect the tips: the two points are the thinnest part of the stone. V-prongs or a bezel on each tip protect them.
• Size up: see 1.5 carat marquise prices and 2 carat marquise prices.

1 carat marquise questions

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

At Lavora Diamonds, a 1 carat marquise lab-grown solitaire (D–E color, VS1+ clarity) in 14K gold lands at the $2,000 complete-ring minimum, including the IGI-certified center, setting and your custom 3D render. Your exact price comes with your 3D render.

Does a marquise cost less than a round?

On our design desk, rates are per carat, not per shape, so a 1 carat marquise prices like a 1 carat round of the same grade. The exact stone you choose sets the final number.

Should I buy a 1 or a 1.5 carat marquise?

Price both. On our ring price estimator, a 1.5ct D–E/VS1+ round solitaire in 14K yellow gold also models at the $2,000 Lavora minimum, and desk rates are per carat, not per shape, so sizing a marquise up to 1.5 carats can cost little or nothing extra at that grade.

How big is a 1 carat marquise diamond?

A 1 carat marquise is shorter than a 2 carat marquise (about 12.7–13.9 mm long, 6.4–6.7 mm wide) and faces up longer than a 1 carat round (about 6.4–6.6 mm across), based on IGI-graded lab-grown stones in our supplier feed in October 2026. We confirm the exact millimeters before production.

Can I get a 1 carat marquise in platinum?

Yes. Platinum and 18K gold are offered and are quoted on your specs; both cost more than the 14K gold in our estimates. We show the metal in your 3D render before production.

How do I pay for a custom 1 carat marquise ring?

Production begins after 3D approval and payment. Klarna and Affirm financing are available on your invoice. Complete engagement rings have a $2,000 minimum.
