Collection: Radiant Cut Lab Diamond Rings
Radiant Cut Engagement Rings
Quick answer: A radiant cut diamond has the trimmed corners of an emerald cut with brilliant style facets, so it combines a clean rectangular or square outline with intense sparkle.
Radiants suit anyone who wants an angular shape without giving up fire. Our radiant cut lab diamond rings come in solitaire, hidden halo and pave designs in solid 14K and 18K gold or platinum. 3 carat radiant rings start from $3,000 USD in 14K gold, and center stones of 2 carats and up come with an IGI or GIA report.
How to Choose a Radiant Cut Diamond
-
Ratio: about 1.00 to 1.05 for a square radiant, 1.20 to 1.35 for a rectangle.
-
Clarity: the brilliant facets hide small inclusions, so VS2 is usually clean to the eye.
-
Color: radiants can hold a little color, so G or better is a safe choice in white gold or platinum.
-
Strong corners: the cropped corners make a radiant less prone to chipping than a princess cut.

Radiant Cut Diamond Ring FAQ
Radiant cut or emerald cut?
Same outline, different sparkle. A radiant has brilliant facets and lots of fire, while an emerald cut has step facets and a glassy look.
Does a radiant diamond look bigger?
A rectangular radiant covers more of the finger than a round of the same weight, though it carries a little more of its weight in its depth than an oval.
Is a radiant cut good for everyday wear?
Yes. The cut corners are strong and less likely to chip, which makes it a practical choice for daily wear.
How much is a 3 carat radiant lab grown diamond ring?
At Future Jewelry, 3 carat radiant rings start from $3,000 USD for a solitaire in 14K gold. Higher grades, 18K gold, platinum and halo settings cost more.
