How big is a 5 carat marquise?

A marquise is a long brilliant cut with two pointed tips. It spreads its weight along its length, so it faces up much longer 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
4ct marquise	about 15.5–17.1 mm long, 8.1–8.5 mm wide
3ct marquise	about 14.5–15.8 mm long, 7.4–7.7 mm wide
5ct round (for comparison)	about 11.0–11.1 mm across

A 5 carat marquise is longer than the 4 carat marquise above. We confirm the exact millimeters on the stone you choose before production, and you check the length on your finger in your 3D render.

Buying tips

• Clarity: VS1+. At 5 carats the table is large, and VS1 is our floor.
• Tips: the two points are the most exposed part of a marquise. Ask for V-prongs on both tips; we show them in your 3D render.
• Bow-tie: most marquise cuts show a darker bow-tie across the middle. Choose the stone from its video, not just the grade.
• Other sizes: see 4 carat marquise prices and 3 carat marquise prices.
