How big is it?
A radiant is a rectangular or square cut with trimmed corners and brilliant-style faceting, so it sparkles more like an oval or round than an emerald cut does. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.
| Center | Face-up size |
|---|---|
| 3ct radiant | about 9.9–10.6 mm long, 7.0–7.2 mm wide |
| 3ct emerald (for comparison) | about 9.7–10.2 mm long, 6.7–7.0 mm wide |
| 3ct round (for comparison) | about 9.1–9.5 mm across |
A 3 carat radiant is a little longer and wider than a 3 carat emerald cut, and longer than a 3 carat round is wide. Compare millimeters, not just carats.
Buying tips
- Clarity: VS1+. Radiant faceting hides small inclusions better than a step cut, but VS1 is still our floor.
- Shape: radiants range from nearly square to clearly rectangular; tell us which outline you want and we match the stone to it.
- Setting: four-prong, hidden halo, pavé and three-stone settings all suit a radiant; we show each option in your 3D render before you commit.
- Radiant vs emerald: similar outline, different look. A radiant sparkles; an emerald cut shows long, mirror-like flashes. See pear and radiant prices.

Radiant or emerald cut: which is better at 3 carats?
It comes down to the look. A radiant has brilliant-style facets and more sparkle, and it hides small inclusions better. An emerald cut has long step facets with a calmer, mirror-like look and shows clarity more, so it needs VS1+. Both are offered at Lavora, and we can render either before you decide.

A completed Lavora 4.50ct F VS1 radiant came to $4,994 complete. For a 5 carat radiant, our 14K E–F/VVS2 solitaire estimate is $4,475–$4,950; see our 5 carat radiant cost page.
What clarity and color should I choose for a 3 carat radiant?
VS1+ clarity and F color or better is a strong spec for a 3 carat radiant. VVS clarity and D–E color are available as upgrades, and every Lavora lab-grown center is IGI-certified.
