1 carat princess cut lab-grown engagement ring price

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

Short answer: at Lavora Diamonds, a 1 carat princess cut 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.

Our design-desk rates are per carat, not per shape, so a princess cut prices like any other shape of the same size and grade on the desk; the exact stone you choose sets the final number. On our ring price estimator, a 1.5ct F/VS1 round solitaire in 14K yellow gold and a 2.0ct F/VS1 solitaire in 14K white gold both model at the $2,000 Lavora minimum, so a 1 carat princess in the same grade 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 princess solitaire in 14K gold is estimated at $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 princess cut?

A princess is a square brilliant cut with four pointed corners. It is cut deep, so it faces up smaller than a round of the same weight. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
1ct princess	about 5.4–5.7 mm per side
1.5ct princess	about 6.2–6.5 mm per side
1ct round (for comparison)	about 6.4–6.6 mm across

A 1 carat princess measures about a millimeter less across than a 1 carat round, but its corners give it a crisp square outline. Your 3D render shows the face-up size on your ring size.

Buying tips

• Clarity: VS1+. Princess faceting is bright and forgiving of small inclusions, and VS1 is our floor.
• Corners: the four points are the vulnerable spots; V-tip prongs or a bezel protect them. You see the corners in your 3D render.
• Squareness: most 1 carat princess cuts in our supplier feed run about 1.00 to 1.02 length-to-width. Look for a ratio close to 1.00 if you want a true square.
• Size up: see 2 carat princess prices and 3 carat princess prices.
