How big is it?

A radiant is a rectangular brilliant cut with trimmed corners. It has emerald-cut lines with round-style sparkle. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
2.5ct radiant	about 9.3–10.3 mm long, 6.5–6.8 mm wide
2ct radiant	about 8.5–9.2 mm long, 6.1–6.3 mm wide
2.5ct round (for comparison)	about 8.7–8.8 mm across

An elongated 2.5 carat radiant can measure longer than a 2.5 carat round is wide, while a near-square radiant faces up smaller. Compare the millimeters on the IGI report, not just carat weight.

Buying tips

• Clarity: VS1+. Radiant faceting is forgiving of small inclusions, and VS1 is our floor.
• Ratio: radiants range from near-square to clearly elongated; pick the outline you want on your 3D render.
• Depth: two 2.5 carat radiants can face up differently, so compare the measurements on the IGI report.
• Other sizes: see 3 carat radiant prices and 4 carat radiant prices.
