How big is it?
An oval is an elongated brilliant cut, so it spreads its weight along its length and looks larger face-up than a round of the same carat weight. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.
| Center | Face-up size |
|---|---|
| 4ct oval | about 12.6–13.4 mm long, 8.8–9.0 mm wide |
| 3ct oval | about 11.4–12.1 mm long, 8.0–8.2 mm wide |
| 4ct round (for comparison) | about 10.2–10.3 mm across |
A 4 carat oval is noticeably longer than a 4 carat round is wide, so it covers more of the finger. Compare millimeters, not just carats.
Buying tips
- Clarity: VS1+. Oval faceting hides small inclusions well, and VS1 is our floor.
- Color: at 4 carats the stone is large enough that color shows more; E–F keeps it bright in white gold or platinum, while G pairs well with yellow gold.
- Bow-tie: many ovals show a darker bow-tie across the middle. Ask us to check the bow-tie on your stone before production.
- Proportions: tell us if you want a slimmer or a fuller oval and we match the stone to your 3D render. See 4 carat ring prices for other shapes.
