How big is a 2.5 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
2ct princess	about 6.8–7.1 mm per side
3ct princess	about 7.8–8.0 mm per side
2.5ct round (for comparison)	about 8.6–8.9 mm across

A 2.5 carat princess sits between the 2 and 3 carat princess sizes above. We confirm the exact millimeters on the stone you choose before production, and you check the face-up size on your 3D render.

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.
• Solitaire or hidden halo: a hidden halo adds sparkle under the center without changing the square outline from the top.
• Other sizes: see 2 carat princess prices and 3 carat princess prices.
