About Radiant-Cut Diamonds

Radiant cut diamonds are abundant in brilliance. The radiant cut emerged in the 1970s, making it a relatively new diamond cut. Its creator, Henry Grossbard, combined the sparkling elements of a round brilliant with the features of an emerald diamond. With 70 facets, a radiant cut diamond has spectacular light performance and an impressive sparkle.

While radiant cut diamonds are a way off the popularity of a round brilliant, they come very close to matching the fire, brilliance, and scintillation of the world’s most popular cut. Radiant diamonds also give a bigger face-up appearance than another cut of the same carat weight, meaning you can get a sparkling diamond with real impact, for a lower price.

GIA Certified Radiant Cut Diamonds

A GIA diamond report will tell you the cut, color, clarity, and carat weight of your radiant cut diamond. It also provides a polish and symmetry grade. The GIA does not give a cut grade for fancy cuts as, unlike the round brilliant, there is a range of proportions that can create a fantastic-looking diamond.

The GIA provides consistent and unbiased diamond reports that are essential to diamond buyers. As a guideline, a table of 61-69% and a depth of 61-67% is considered the best for radiant cut diamonds.

Radiant Cut Diamond: Frequently Asked Questions

Need to know more? Here are some of our frequently asked questions from customers looking to buy a radiant-cut diamond.

Yes! A well-cut radiant diamond will have a bigger face-up appearance than a round brilliant diamond and step-cut diamond. Their elongated shape, facet patterning, and brilliance all create the ‘illusion’ of a larger diamond.

If you’ve done a little research, you will notice that radiant-cut diamonds are considerably cheaper than other diamond cuts. In fact, the savings can be significant. The shape and cutting process of a radiant diamond means that much of the original rough can be retained – this, combined with the fact that radiant diamonds are a comparatively new cut means that prices are considerably lower.

As mentioned above, the GIA does not issue a cut grade for radiant cut diamonds. They feature a non-standardized facet patterning which means there is a wider range of proportions that can still result in a beautiful diamond.
