How big is a 2.5 carat marquise?

A marquise is a long, boat-shaped brilliant cut with two points. It has one of the longest outlines per carat, so it looks larger face-up 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 marquise	about 12.7–13.9 mm long, 6.4–6.7 mm wide
3ct marquise	about 14.5–15.8 mm long, 7.4–7.7 mm wide

A 2.5 carat marquise sits between the 2 and 3 carat sizes above. We confirm the exact millimeters on the stone you choose before production, and you check the length on your 3D render.

Buying tips

• Grade changes the price: on our estimator the D–E/VS1+ hidden halo row is lower than the D–E/VS1+ solitaire row at the same size, so price both grades.
• Clarity: VS1+. VS1 is our floor.
• The points: both tips are vulnerable, so ask for V-prongs on each end. You see the prongs in your 3D render.
• Other sizes: see 2 carat marquise prices and 3 carat marquise prices.
