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. We have no completed princess build to publish yet. A hidden halo, pavé band, 18K gold or platinum move the number up, and your exact price comes with your 3D render. Complete engagement rings have a $2,000 minimum.

How big is it?
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 |
|---|---|
| 3ct princess | about 7.8–8.0 mm per side |
| 2ct princess | about 6.8–7.0 mm per side |
| 3ct round (for comparison) | about 9.2–9.4 mm across |
A 3 carat princess measures more than a millimeter less across than a 3 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: look for a length-to-width close to 1.00 if you want a true square.
- Loose-stone prices: see princess cut lab-grown diamond prices for loose princess vs round prices.

Princess cut questions
How much is a 3 carat princess cut lab-grown engagement ring?
At Lavora Diamonds, a 3 carat princess cut lab-grown solitaire (E–F color, VVS2 clarity) in 14K gold is estimated at about $2,775 ($2,625–$2,925) complete on our design desk, including the IGI-certified center, setting and your custom 3D render. Your exact price comes with your 3D render.
Is a princess cut cheaper than a round at 3 carats?
Loose princess stones often price somewhat under rounds of the same grade because the cut keeps more of the rough crystal. 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.
How big is a 3 carat princess cut diamond?
Based on IGI-graded 3 carat lab-grown princess cuts in our supplier feed in October 2026, a 3 carat princess measures about 7.8–8.0 mm per side, compared with about 9.2–9.4 mm across for a 3 carat round.

V-tip prongs wrap each of the four corners in metal, and a bezel shields the edges entirely. We show the corner setting in your 3D render before production.
