Our guide to Round cut diamonds
Our tips for finding the Round cut diamond meant just for you.
The Round cut is the most popular of all diamond shapes. The Round Brilliant cut was created for ultimate brilliance. It features 58 angular facets amongst its crown, girdle and pavilion. The arrangement of these facets is optimal for interacting with the light, which is why the Round Brilliant is considered the most brilliant diamond of them all.
The best engagement ring setting for a Round cut diamond is the one that’s right for you. And although this diamond shape looks stunning in all engagement rings, there are best-selling designs that are considered timeless.
A Solitaire engagement ring, such as a Classic, Signature Solitaire, or Cathedral engagement ring, are perfect for highlighting the Round’s renowned brilliance. Three Stone Engagement rings as well as the Toi et Moi engagement ring are wonderful for mixing the Round with other diamond shapes for a balanced look that is both modern and classic. For those wanting to buy an engagement ring that is vintage-inspired, the Halo or Duet pair perfectly with this beloved shape.
The 4Cs are important to consider when it’s time to buy diamonds. When selecting your Round diamond, consider prioritizing cut. An excellent cut will highlight this shape’s renowned brilliance.
Clarity is important when considering the design a Round cut will be featured in — inclusions might be less visible in Solitaire Studs or a necklace than in an engagement ring, for example.
The color of your diamond also depends on the color of your design; a colorless diamond works best in platinum or white gold, whereas nearly colorless diamonds are better in yellow gold settings.
The Round cut’s size is true to its carat weight. For those wanting a more substantial center stone, they will have to consider purchasing a larger diamond.
The main difference between Oval and Round Brilliant diamonds is that the Round is a perfect circle while the Oval is elongated. Its elongated form can make it appear larger than a Round Brilliant of the same carat weight.
Both lab-grown diamonds feature brilliant cut facets for maximum shine. A Round Brilliant is the world’s most popular diamond shape, while the Oval, a more modern shape, continues to grow in popularity. This means that Ovals are often more affordable due to a slightly lower demand.
