How big is a 2.5 carat oval hidden halo?

A hidden halo is a ring of small diamonds set under the center stone, below the girdle. From the top you see the oval outline; from the side you see the extra sparkle. Center measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

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

A hidden halo does not change the face-up outline of the oval; the center sizes above are what you see from the top. We confirm the exact millimeters on the stone you choose before production, and you check the halo from every angle on your 3D render.

Buying tips

• Clarity: VS1+. Oval faceting hides small inclusions well, and VS1 is our floor.
• Bow-tie: many ovals show a darker band across the middle. It is not on the certificate, so ask us to show you the exact stone before production.
• Hidden halo or three stone: a hidden halo keeps a clean solitaire look from the top; a three-stone setting adds side stones you see face-up.
• Other sizes: see 2.5 carat oval prices and 3 carat oval prices.
