How big is a 4 carat princess cut?

A princess is a square brilliant cut with sharp corners. It carries more of its weight in depth than a round, so compare millimeters, not just carats. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
2ct princess	about 6.8–7.0 mm per side
3ct princess	about 7.8–8.0 mm per side
4ct round (for comparison)	about 10.2–10.4 mm across

A 4 carat princess is larger than the 3 carat princess 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+. At 4 carats the table is large, and VS1 is our floor.
• Color: large stones show body color more; D–E keeps a 4 carat princess bright, especially in white gold or platinum.
• Corners: the four points are the most exposed part of a princess. Ask for V-prongs on the corners; we show them in your 3D render.
• Other sizes: see 3 carat princess prices and 2.5 carat princess prices.
