What Are Radiant Cut Diamonds and What You Should Know About Them?

Radiant cut diamonds possess beautiful symmetry, a non-traditional look, and the conjoined brilliance of the round cut and the purity of the emerald cut. With trimmed corners, this cut has enough versatility to be able to shine in almost all kinds of jewelry, including engagement rings. The faceting used in radiant cuts allows them to give off a fiery look which far surpasses that of the princess cut, while still resulting in soft and cut corners. Taken in general, it may be said that the Radiant is a cut that combines some of the most well-liked traits of the popular diamond shapes.

Also known as the “rectangular modified brilliant”, the radiant cut gives you a stone which is basically the squarer version of the Round Brilliant. Radiant cut diamonds fall in a group called “hybrids”, which makes sense since their characteristics seem to be combinations of those of other stone shapes. Radiant cut rectangular diamonds are an excellent option for lovers of the emerald cut, who are also looking for something with the brilliance of the round shape. Radiant cuts are also available in square shapes, the difference here being in the length to width ratio. The latter are also very popular among fancy colored diamonds.

What Is The History Of Radiant Cut Diamonds

The modern radiant cut is under 40 years old. The first ever created was designed by Henry Grossbard in the late ‘70s. He was a member of Radiant Cut Diamond Company, which released the first ever Radiant cut stone in 1977. The new creation was innovative to the scene of rectangular diamonds, and quickly changed the way these were viewed and developed. Grossbard’s new cut boasted a complicated facet pattern right on the crown and the pavilion of the stone. Earlier rectangular-shaped diamonds had fewer facets than this one, and also brought less attention to the smaller details. Grossbard’s version even shone more.

What Is A Radiant Cut Diamond Setting

Engagement rings featuring radiant cut diamonds are known the world over for their unmatchable shine. After a buyer has chosen to go with this cut, the next thing they would need to do is fix on the best setting to complement it on a ring. The most well-liked setting for this among consumers is the four-prong setting. While there is still hot debate on 6-prongs vs 4-prongs, the latter is able to much better emphasize the rectangular or square shape of the stone set in it.

There is also the bezel setting to consider, although they are not advisable for use with radiant cut stones. This is because a bezel affords a closed area for the center stone to sit in, and while this produces a cohesive and secure feeling, it does so at the cost of the light entering the stone. In short, it messes with the shine coming out of the center stone, and that more or less defeats the purpose of showing off a diamond.

Ultimately, it all comes down to personal choice. That said, some settings do better highlight radiant cut stones. There is, for instance, the solitaire setting which uses prongs as holds. Prong settings are called that because they have prongs or metal claws that hold the stone in place. These days you can have flat, rounded, or pointed prongs, and as already mentioned, the number of prongs is something you can choose. The 6-prong setting does hold the diamond more securely, if you were wondering.

Plenty of people swear by the halo setting for their radiant cut diamond. This setting is flashier than the solitaire, but still manages to exude elegance and timelessness. You would have plenty of options to personalize a radiant cut ring if you went this way. For instance, changes can be made to the metal choice to drastically change the ring’s overall look. For instance, going with the rose gold option can give the ring a kind of warm glow which would be absent in a white gold ring.

The Radiant Cut Vs The Cushion Cut

While Cushion cut and Radiant cut stones look very much similar, their shapes do differ on a fundamental level. The latter have rectangular outlines, with cut corners. Cushion cut stones on the other hand have rounded sides, which prevent the rectangular appearance you see in all Radiant cut diamonds. Cushion cut diamonds can sometimes even appear oval in shape, based on the length to width ratio you choose to go with.


One main advantage of the radiant cut is that it easily allows hiding blemishes and inclusions. It is unlike other cuts, which generally draw attention to the flaws in the stone instead of hiding them. The radiant cut is also very versatile, in that it matches well with a good number of ring styles and settings.
