Different diamond shapes have distinct features that make them stand out from the others. Buyers love the round cut due to the classic shape. Those buyers who like extraordinary designs usually go for the Asscher cut, as the cropped corners of the diamond are very appealing. At the same time, vintage design lovers usually go for the emerald cut due to the presence of elegant open facets.

If you are looking to experience all three characters in a single cut, then you can go for the radiant cut diamonds. These diamonds exhibit a perfect balance of brilliance, bold facet style, and unique cut. A combination of all these features allows radiant cut diamonds to offer outstanding brilliance, fire, and scintillation.

History of Radiant Cut

Radiant cut is a comparatively newcomer when compared to other diamond cuts, and has been in existence for just about forty years. The creator of this cut, Henry Grossbard, designed the cut in 1977. While designing it, he was looking to combine the fiery brilliance of the round cut and the elegant, long shape of emerald cut.

Cut Quality

Before even thinking about the style or size of the diamond, you need to take into account the cut quality, as it is the maker or breaker of diamond brilliance. Even though radiant cut diamonds do not have their cut graded by the popular gemological labs such as AGS and GIA, there are many cut proportions for you to choose from.

There are seventy facets in the pavilion and crown of the diamond and they are precisely contoured to offer great brilliance and fire, which can only be topped by the round cut diamonds. Many buyers assume that princess cut diamonds are designed with brilliant cut facets in the pavilion and crown making them sparkle like the round cut diamonds. However, they only come second to the radiant cut.

In terms of aesthetics, the corners of radiant cut diamonds are cropped and can be considered a mix of a cushion cut and a princess cut diamond, making them very much pairable with these two shapes. Owing to the beveled corners of these diamonds, they offer very high durability that is perfect for women with an active lifestyle.

Shape Composition

Usually, radiant cut diamonds are rectangular. However, you can also find varieties that are square looking. Some of the buyers might confuse square radiant cuts with cushion cut diamonds. Yet the noticeable difference is in the internal structure of the diamond. Radiant cuts have a signature sparkle and more facets.

Interesting Diamond Facts

To differentiate a square radiant cut from a rectangle one, you have to understand that the former will have more brilliance; this makes it a better candidate for solitaire setting. The longer radiant cut diamonds will have more fire though, and that can be great in necklaces.

If you like the square shape, then the princess cut will be more appealing. Radiant cut diamonds are in fact called as “cut corner square modified brilliant” or “cut corner rectangular modified brilliant” by the GIA, as they see the radiant cuts as princess cut diamonds with the corners cut off. However, you need to understand that there is much more to radiant cut diamonds than its shape. They are really bright square diamonds, which exhibit concentric circles of light that radiates from the centre of the stone.

Length-to-Width Ratio

As the complex insides of diamond have symmetrical webbing of the facets, diamond cutters ensure that everything is proportioned to get the best scintillation. The length-to-width ratio of the diamond shows how proportionate the diamond is based on the shape that was intended by the cutter (rectangle or square).

The classic range of length-to-width ratio is from 1.00 to 1.35, where 1 is the perfect square. The diamond will look more rectangular if you go up to ratio of 2.0.

Radiant Cut Clarity

You might have spotted a radiant cut diamond with very good cut quality. However, not knowing about the clarity of the diamond can make you end up with an unpleasant diamond. If the radiant cut diamond that you choose is eye-clean, meaning that there are not any inclusions in the diamond that are visible to the naked eye, then it will obviously be a good buy.

With so many facets in a radiant cut and the crushed ice look, inclusions and flaws can be very well hidden. Going for the high clarity grade diamonds will only cost you more money, while they will look the same as an eye-clean diamond.

Bowtie Effect

Even though the bowtie effect is very evident in cuts like pear and oval cut diamonds, some of the radiant cut diamonds also show bowtie effect. This will not be mentioned in the diamond certificate, so it is better to visually inspect the diamond before buying it.
