1 carat cushion cut lab-grown engagement ring price

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

Short answer: at Lavora Diamonds, a 1 carat cushion or elongated cushion 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 cushion prices like any other shape of the same size and grade on the desk; the exact stone you choose sets the final number. The square and elongated versions price the same way on the desk. 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 cushion 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 2.0ct D–E/VS1+ solitaire in 14K yellow gold is $2,175–$2,425, and a 3.0ct D–E/VS1+ elongated cushion hidden halo is $2,900–$3,225. Your exact price comes with your 3D render. Complete engagement rings have a $2,000 minimum.

How big is a 1 carat cushion?

A cushion is a brilliant cut with soft, rounded corners. The square version reads classic and compact; the elongated version stretches the outline, so it faces up longer on the finger. 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
1.5ct square cushion	about 6.5–7.1 mm long, 6.4–6.7 mm wide
1.5ct elongated cushion	about 7.6–8.5 mm long, 5.7–6.3 mm wide

A 1 carat cushion faces up smaller than the 1.5 carat cushions above. We confirm the exact millimeters on the stone you choose before production, and you check the outline on your 3D render.

Buying tips

• Square or elongated: decide this first. An elongated cushion looks longer on the hand; a square cushion reads softer and more vintage.
• Clarity: VS1+. VS1 is our floor.
• Faceting: cushions vary a lot in how their facets look. Ask to see the stone video and check the look in your 3D render.
• Size up: see 1.5 carat cushion prices and 2 carat cushion prices.

1 carat cushion cut questions

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

At Lavora Diamonds, a 1 carat cushion or elongated cushion 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 1 carat elongated cushion cost more than a square cushion?

Not on our design desk. Rates are per carat, not per shape, so square and elongated cushions of the same size and grade price the same way. The exact stone you choose sets the final number.

Should I buy a 1 or a 1.5 carat cushion?

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 cushion up to 1.5 carats can cost little or nothing extra at that grade. A 2.0ct D–E/VS1+ solitaire in 14K yellow gold is $2,175–$2,425.

How big is a 1 carat cushion diamond?

A 1 carat cushion faces up smaller than a 1.5 carat square cushion (about 6.5–7.1 mm long) or a 1.5 carat elongated cushion (about 7.6–8.5 mm long), 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 cushion 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 cushion 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.
