On our ring price estimator, a 1.5ct F/VS1 round solitaire in 14K yellow gold models at the $2,000 Lavora minimum.

How big is a 1.5 carat radiant?

A radiant is a rectangular or square brilliant cut with trimmed corners. Most 1.5 carat radiants are rectangular, so they face up longer and narrower than a round of the same weight. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
1.5ct radiant	about 7.8–8.5 mm long, 5.6–5.9 mm wide
2ct radiant	about 8.8–9.2 mm long, 6.2–6.4 mm wide
1.5ct round (for comparison)	about 7.3–7.5 mm across

Going from 1.5 to 2 carats adds about one millimeter of length to a radiant. Compare millimeters, not just carats, and check the outline on your 3D render.

Buying tips

• Clarity: VS1+. Radiant faceting hides small inclusions well, and VS1 is our floor.
• Ratio: most 1.5 carat radiants in our supplier feed run about 1.36 to 1.50 length-to-width. Lower reads squarer, higher reads more elongated.
• Corners: the trimmed corners of a radiant are less exposed than sharp corners, and a four-prong or bezel setting covers them. Ask to see the prongs on your 3D render.
• Size up: see 2 carat radiant prices and 2.5 carat radiant prices.
