Diamond Face-Off: Oval vs. Radiant
Oval shapes and radiant cuts are the two most popular shapes of the last several years. Since the two are fairly different in appearance, choosing between them could be difficult. We’re here to break down each cut and see how they compare and contrast.
Oval Shape Diamonds
While we don’t know exactly who cut the first oval shape diamond, we know that they were worn by royals hundreds of years ago. However, the brilliant cut oval shape we know today was introduced in the 1960s by Lazare Kaplan. Oval diamonds are the most popular shape and have been for the last 5 years.
Ovals are a graceful elongated shape with rounded edges, essentially the elliptical version of the round brilliant cut. Ovals typically feature 58 facets which are cut to enhance maximum light reflection and brilliance.

Radiant Cut Diamonds
The radiant cut was developed by Henry Grossbard in 1977. Grossbard wanted to create a new diamond cut with the shape of an emerald cut and the sparkle of a round brilliant. Radiant cuts are often rectangular in shape and feature cut corners with brilliant faceting.
Radiants are considered one of the most brilliant diamond cuts available boasting 70 facets whereas other brilliant cuts, like the oval, only have 57-78. Just as Grossbard intended, radiant cuts are hugely popular for those who want the shape of an emerald cut but the brilliance of a round.

Oval vs. Radiant Ratios
Since ovals are naturally elongated shapes, the ratio you choose will mostly affect its width. If you’re looking for a rounder and more compact oval, look for a stone with a ratio in the 1:1.3 range. If you’re looking for a thinner, more elongated oval, these stones will have a ratio above 1.4, closer to 1.5 ratio. A good middle ground would be around a 1.4 ratio.
As for radiant cuts, there are basically only two options: elongated and rectangular or square. If you are looking for an elongated radiant cut, an acceptable ratio would be 1:1.3 to 1:1.4. However, if you are looking for more of a square cut radiant, look for a ratio closer to 1:1 and a little above.
Oval vs. Radiant Cut Comparison
Looking at the two, ovals and radiants are not very similar in appearance; ovals are the elliptical adaptation of a round while radiants are rectangular in shape with cut corners.
While oval shapes and radiant cuts are both brilliant cuts, ovals only have 58 facets where radiants have 70. However, both cuts are elongated brilliant cuts with similar faceting patterns that are meant to maximize sparkle.
Where radiants might have more brilliance, ovals will usually appear larger in size than their actual carat weight because of their elongated shape.
Oval vs. Radiant Quality Comparison
Ovals show color quite easily because they have a large surface area. Because of this, we recommend opting for an I color or above. On the other hand, ovals are great at hiding imperfections, so we can safely recommend opting for an (eye-clean) SI2 oval.
Radiant cuts are great at hiding color and inclusions so we can confidently recommend a color graded as low as J and an eye-clean SI2 for clarity.
As a reminder, it is always a good idea to see each diamond in person to assess as not all diamonds, inclusions, and/or grading labs are equal.
