What are Radiant Diamond Rings?

Radiant diamond rings are rings that feature a radiant cutting quality. It possesses the unique elements and combination of an emerald and round shape with identical 70 facets, giving substantial fire and brilliance. Although round diamonds are ideal for anyone wanting maximum sparkle, the radiant cut is a perfect alternative.


Radiant cut diamonds aren’t just excellent for rings but for diamond earrings. They have a larger perceived size than other fancy diamond cuts of similar carat, making it okay to go low on the carat on your radiant cut engagement rings and earrings.


Its upward area might be small, but it possesses a long diagonal measurement that will trick your vision and make you believe it is bigger than its original size. It is a better choice than most fancy diamond shapes like the princess cut.


Although it is generally classified as a square cut like others with similar silhouettes, it is more durable because of the angular edge slant, making it less vulnerable to chipping. And opting for radiant-cut diamond rings means you get to spend less on a stunning diamond that offers almost the same quality and sparkle as the round-cut diamond.

Factors to Consider When Buying Radiant Diamond Rings

Radiant cut diamonds follow the same quality assessments as other diamonds in all four characteristics. When buying these types of rings, below are some factors to consider.



Radiant diamonds have no GIA cut grade, meaning it solely depends on the diamond cutter to achieve a perfect shape. Regardless, some factors guide you when assessing a radiant diamond’s cut.


An ideal table for a radiant cut ranges from excellent to poor. A table of 51% to 79 % is acceptable, although you should try to remain between ‘excellent and very good.’ Going lower than 51% or above 795 is poor and produces a poor-quality radiant diamond.


The radiant diamond’s depth is also graded from excellent to poor, so stick with the ‘excellent or very good depth.’ Going for the ‘good and fair’ grades isn’t always recommended as it affects the diamond’s sparkle and brilliance.


An exceptional radiant cut diamond should have a ‘very thin to slightly thick’ girdle. Going above this will negatively impact its beauty.


A well-cut radiant diamond should have no culet or anyone larger as this hinders the diamond’s brilliance and may appear as an inclusion.

The length-to-width ratio is another crucial element determining your diamond’s cut. In this case, there isn’t any set ratio as it depends on you and which you prefer. However, a recognized measurement for this ratio is 1.00-1.35 and may slightly surpass it to 2.0.


Radiant cut diamonds have a crushed ice appearance due to their several facets and angles. As a result, they mask inclusions perfectly, meaning you can afford to compromise on its clarity grade. This makes an S1 or S2 clarity perfect for you, but you should ensure it is entirely eye-clean before choosing it.


Color is another area you can compromise on, but carefully. Although a diamond’s cut and clarity are vital, so are other qualities; hence when considering going low on any characteristic, don’t overdo it.

It is safe to go from colors D to I is colorless or near-colorless and offers that sparkly white color. But if you decide to go for J to K, it would be best to use them on colored precious metals like yellow and rose gold.


The carat of your radiant diamond depends on you. You may go high or low as you wish but if you’re on a budget, going for a 1.0 carat isn’t bad. After all, radiant diamonds have a large perceived size, and you can use a halo setting to amplify their size and sparkle.

Precious metals/Settings

You should know that the metal you use for your radiant color can amplify or lessen its beauty regarding the diamond’s clarity and color.

Colored metals make a slightly yellow/brown tinted diamond look beautiful, but platinum or white gold metal makes that color stark, and you may not want that. Also, use a similar prong color and tiny colorless diamond to surround it in a halo design.

Where to Buy Radiant Diamond Rings in Singapore?
