Radiant Cut Diamonds
A relatively new diamond shape, the radiant cut was designed by Henry Grossbard in the late 1970s. He created a cutting technique that combined the best elements of emerald and round diamond shapes–allowing radiant diamonds to exhibit incredible brilliance and fire.
What is a radiant diamond?
True to its name, this cut is truly radiant. While the octagonal shape and cropped corners do make it similar to the emerald cut, the faceting is reminiscent of the round brilliant cut.
This combination gives radiant diamonds considerable fire and sparkle.
With 70 facets, the radiant cut is one of the most brilliant diamond shapes available today. It’s a new cut, created just over 30 years ago by master diamond cutter Henry Grossbard who worked to combine the best elements of the emerald and round brilliant cuts.
The radiant is often labeled as a cut-cornered rectangular or square modified brilliant by the GIA when grading diamonds of this shape.

Why should I choose a radiant diamond?
Radiant cut diamonds possess a silhouette shape very similar to an emerald shape, but its facets are cut in a more similar way to that of round diamonds. This means that the appearance of the diamond has an effervescent sparkle, hypnotizing those who catch its gaze.
Though the radiant has only been available for a short time, it has quickly increased in popularity. You’ll always find radiant diamond engagement rings listed in the most popular styles.
Radiant cuts are perfect for those loving the contours of an emerald cut but craving the sparkle of a round brilliant cut diamond.
Radiants are also ideal cuts for colored diamonds. Due to its faceting structure, this cut provides a depth which emphasizes the color tones of any diamond.
Ratios for radiant cut diamonds depend on personal preference. The most common ratio for a traditional, rectangular shaped radiant cut diamond is 1.25 although ratios range from 1.05 – 1.50. For a square radiant cut, a ratio between 1.00-1.05 is ideal.
Elongated radiant cut
The ratio significantly impacts the diamond’s visual characteristics. A higher ratio (greater than 1.3) creates a more rectangular appearance, while a lower ratio (around 1.0 to 1.3) results in a squarer shape.
The elongated radiant cut combines the best of both worlds: the dazzling sparkle of brilliant cuts and the elongated silhouette reminiscent of emerald cuts. This blend of characteristics allows for a striking balance between fire and geometry, making it an ideal choice for those who appreciate a fusion of classic and modern aesthetics. Due to its elongated form, this cut can create a flattering visual effect on the finger, making it appear slender and graceful. Additionally, the elongated shape can also make the diamond stand out in various settings, from solitaire rings to halo designs. In summary, the elongated radiant cut offers a refreshing twist on the classic radiant cut, delivering a sophisticated and captivating diamond that combines timeless brilliance with a contemporary elongated silhouette.

Radiant Diamond Color
What color is best for a radiant diamond?
Evaluating color in radiant cut diamonds is entirely dependent on the preference of its buyer or wearer.
Diamonds in the colorless range (D-F) carry a premium due to the fact that they are incredibly rare, but the truth is, the difference between the colorless and near colorless (G-J) grade ranges is difficult to perceive, especially to the naked eye.
| Excellent | Very Good | Good | |
|---|---|---|---|
| <0.50ct | D-G | H-I | J |
| 0.51-1.00ct | D-F | G | H-I |
| 1.00-2.00ct | D-F | D-F | G-H |
| >2.00ct | D-F | D-F | G |
Radiant Diamond Clarity
What clarity should I choose for a radiant cut diamond?
When diamonds are formed deep in the earth, they develop clarity characteristics–slight irregularities visible under 10x magnification. Depending on the size, quantity, placement, tone or color of these clarity characteristics, they may or may not be visible to the naked eye. This is one of the reasons why a truly flawless diamond is so rare and carries a price premium.
When it comes to choosing diamond clarity, the choice is yours. Some may be happy with a diamond that features clarity characteristics that aren’t visible to the naked eye, while others desire absolute perfection with a technically flawless clarity grade.
Due to their extra facets, radiant cut diamonds disperse more light throughout the diamond, giving clarity characteristics (inclusions) more places to hide. For this reason, you can consider choosing a lower clarity grade.
| Excellent | Very Good | Good | |
|---|---|---|---|
| <0.50ct | FL-VS2 | SI1 | SI2 |
| 0.51-1.00ct | FL-VS1 | VS2-SI1 | SI2 |
| 1.00-2.00ct | FL-VVS2 | VS1-VS2 | SI1-SI2 |
| >2.00ct | FL-VVS2 | VS1-VS2 | SI1 |
Radiant vs emerald cut
Radiant and emerald cuts are popular diamond shapes frequently used in jewelry, each boasting its own unique attributes and allure. Let’s delve into a comparison of their distinctive features:
When it comes to the way they reflect light:
The radiant cut stands out for its remarkable facet arrangement, combining the brilliance seen in round brilliant cuts with the sophisticated outline of square or rectangular diamonds. This cut showcases a captivating arrangement of triangular and kite-shaped facets that extend from the center outward, producing a mesmerizing interplay of light.
On the other hand, the emerald cut features a step-cut facet pattern that accentuates its clarity and transparency. Its rectangular form displays broad, open facets adorned with parallel lines resembling a set of steps. This approach emphasizes the diamond’s clarity and creates a more understated light reflection compared to the dazzling effect of brilliant cuts.
Considering their brilliance and sparkle
The radiant cut is designed to maximize sparkle and brilliance, similar to round brilliant cuts, thanks to its intricate facet design. This makes it an excellent choice for those who desire a diamond with exceptional radiance and vibrancy.
In contrast, the emerald cut prioritizes the diamond’s clarity and transparency over intense sparkle. While it may not exhibit the same level of brilliance as the radiant cut, it possesses a distinctive and refined beauty that appeals to those with a penchant for understated elegance.
Taking into account their clarity attributes
The radiant cut’s faceting serves to conceal minor imperfections and inclusions within the diamond, contributing to its overall brilliance and appeal.
On the other hand, the emerald cut’s step-cut facets are less forgiving when it comes to flaws and imperfections. This characteristic tends to accentuate the diamond’s clarity, leading to a preference for higher clarity grades.
