How big is it?

An oval is an elongated brilliant cut, so a 2.5 carat oval looks larger face-up than a 2.5 carat round. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
2.5ct oval	about 10.7–11.4 mm long, 7.5–7.8 mm wide
2ct oval	about 9.9–10.6 mm long, 7.0–7.2 mm wide
3ct oval	about 11.4–12.1 mm long, 8.0–8.2 mm wide

Going from 2 to 2.5 carats adds just under a millimeter of length; going on to 3 carats adds about the same again. Your 3D render shows the face-up size on your ring size before anything is made.

Buying tips

• Clarity: VS1+. Oval faceting hides small inclusions well, and VS1 is our floor.
• Color vs carat: grades move price as much as size. The completed 2.50ct D–E/VS1+ oval above came in under the VS1+ estimator range.
• Setting: solitaire, hidden halo, three-stone and pavé all suit a 2.5ct oval; we show each option in your 3D render before you commit.
• Bow-tie: ask us to check the bow-tie on your stone before production. See 2.5 carat ring costs for other shapes.
