In this article, we’ll take you through the main differences between Emerald cut and Radiant cut in terms of diamond cut, facets, sparkle, size, length to width ratio, clarity, and color to help you make a wise choice when choosing the best rectangular diamond for your style.

The Emerald cut is a diamond cut characterized by its rectangular shape and parallel step-cut facets. Emerald cut diamonds have a larger length to width ratio, emphasizing a slender shape. They typically feature 57 step-cut facets arranged in parallel lines, giving it a stepped appearance and a “hall of mirrors” effect. This unique facet style gives the Emerald cut diamond an elegant and bright look, making it a popular choice for engagement rings and other high-end jewelry!

The Emerald cut is also known for its large table, the flat top of the diamond. This large table helps showcase the diamond’s clarity and color, allowing the diamond to sparkle with dazzling brilliance, making the Emerald cut an ideal choice for those seeking diamonds of exceptional quality.

The Radiant cut is a diamond cut that combines the features of the round brilliant cut and the Emerald cut, characterized by its rectangular shape and a pattern of 70 brilliant facets.

As a more modern diamond cut style, the Radiant cut was invented by Henry Grossbard in 1977. He was the first to use a pattern of brilliant facets on both the crown and pavilion of a gemstone, successfully creating one of the most brilliant cuts. This hybrid cut is one of the most faceted diamond styles, designed to maximize the natural beauty of the diamond and create a crushed ice-like effect. The Radiant cut is also known for its deep pavilion, which further enhances the diamond’s brightness by reflecting light from various angles, creating stunning flashes of light and color.

Another advantage of the Radiant cut diamond is its versatility, as it can be set in various styles, including solitaire, halo, and three-stone settings. This makes it a popular choice for engagement rings and other jewelry, as it can be customized to individual preferences and styles.

The Emerald cut, with its 57 step-cut linear facets, has a more glassy, conservative appearance, while the Radiant cut boasts 70 triangular or kite-shaped facets radiating from the center, maximizing the gem’s inherent fire and brilliance.


The Radiant cut is renowned for its intense sparkle and fire due to its numerous facets and deep pavilion, akin to shattered glass glittering in the sunlight. On the other hand, the Emerald cut is known for its understated and subtle sparkle due to its clean lines, step-cut facets, and large table.

Length-to-width Ratio:

The ideal length-to-width ratio for an Emerald cut diamond is 1.40, while for a Radiant cut diamond, the ideal ratio is 1.25. Therefore, the Emerald cut diamond will appear more rectangular compared to the Radiant cut diamond.

Clarity and Color:

The step-cut arrangement of the Emerald cut makes internal flaws more visible compared to the Radiant cut, but the facets of the Emerald cut can help mask yellow hues. The large table of the Emerald cut diamond highlights inclusions, so when choosing an Emerald cut engagement ring, you can invest in a lower color grade (H or I) with a VS2 or higher clarity. For a Radiant cut engagement ring, you can find with SI1 or SI2 clarity and upgrade to a higher color grade since the facet style of the Radiant cut is more forgiving of internal flaws, using strong brilliance to mask inclusions.

Similarities Between Radiant Cut and Emerald Cut

Both Radiant cut and Emerald cut diamonds share a similar rectangular shape with diagonal or cut corners, giving them a linear octagonal design that makes them more durable and less prone to chipping. The elongated shape of the rectangular Emerald and Radiant cut diamonds creates the illusion of a larger size compared to diamonds of the same carat weight but different shapes.

Moreover, the slender shape of the diamond also makes the wearer’s fingers appear longer and more delicate, which is one of the reasons why Emerald cut and Radiant cut diamonds are so popular. Despite their unique facet styles, both Radiant and Emerald cut diamonds are fancy-shaped diamonds that provide a beautiful way to showcase the natural beauty of the diamond.
