Like with every diamond cut, you have attend to the specific details of the stone before you purchase a radiant cut engagement ring. Here are some the details that you should examine if you have plans of purchasing a radiant cut diamond engagement ring.

Selecting The Right Proportions Of Radiant Cut Diamonds

GIA lists the cut grade for a round cut diamond but things are not the same with a radiant cut diamond and as they have non-standardized facet structures, there exists a wide range of cut proportions for it. As the radiant cut lack cut information offered by a lab report, selecting a radiant cut of fine quality will not be an easy task for an inexperienced shopper.

The quality of radiant cut is determined by the percentages of depth, table, and symmetry. 60-66% table percentage and 59-65% depth percentage will make excellent contributions to cut quality.

Selection Of Length To Width Ratio

The length to width ratio of the diamond decides whether it looks rectangular or square and the ratio is determined by dividing the length of the diamond by its width. The ratio that you select depends on the shape that pleases your aesthetics and the common ratio range is 1.00 to 1.35. The ratios closer to 1 are characteristic of square shaped radiant cuts while rectangular radiant cuts have comparatively higher ratios.

Look For Bow Tie Effect

Dark looking flaws in a diamond are characteristic of the bow tie effect and as the name suggests, the flaw resembles the shape of a man’s bow tie. The effect is caused by the misalignment of facets in the diamond, which blocks the entry of light into the diamond.

A clear inspection of the diamond in person can help you spot the flaw easily and if found, you should avoid buying the diamond.

Color Rating

Radiant cuts cannot beat round cut diamonds in brilliance, which is why they tend to show more color than a round cut. The color range is between D to Z and on moving from D to Z, the diamonds turn from colorless to colored. Diamonds in the grades closer to Z show a noticeably yellow or brown tint.

With radiant cuts, the color of the diamonds is even more visible and if you want a clear diamond, it is better to look for color grades close to D. However, the difference in color of the D to H grade diamonds cannot be distinguished easily and you can choose color grades till H if you wish to spend your budget on other aspects like clarity.


The radiant cut has large table facet and relatively poor light return that compromises its ability to hide inclusions. The clarity grade that you select also depends on the carat size of the diamond and with larger carat sizes, you may require higher clarity rating.

The clarity scale of diamonds as per GIA ranking is between IF(internally flawless) and I2. On moving from IF to I2, the number of inclusions in the diamond keeps increasing. The radiant cut has many facets and angles that give it the appearance of crushed ice, the structure that helps hide inclusions better and selecting S1 or S2 grades that have small number of inclusions wouldn’t compromise much on the clarity.


Many labs certify radiant cut diamonds, but not all of them are trustworthy. GIA and AGS certifying labs have better accuracy and consistency when compared to many other diamond-certifying labs. Lab certificates guide you better in the diamond purchase process but they do not decide how the diamond will appear and you have to inspect the diamond in person to make sure it is eye clean.


Radiant cut diamonds cost less than round cut diamonds, which means that you get a larger diamond for less money. During the cutting process of round diamonds, there is high wastage of rough diamonds but the wastage associated with the cutting process of radiant cuts is comparatively low. Since the cutting process of radiant cut diamond uses a larger percentage of the rough diamond, the price per carat of radiant cut diamonds is lower than that of round cut diamonds.
