Welcome back to our "Guide: Gemstone Cuts" series!
This week, we're putting the two most popular styles head-to-head: the timeless Round Brilliant and its fashionable counterpart, the Oval Cut.
Both are "brilliant" cuts, meaning they are designed for one primary purpose: maximum sparkle. But they wear that sparkle very differently.
See Them in Action: The Battle of the Brilliance
The classic icon or the modern favourite? Watch our side-by-side comparison to see the unique way these two brilliant cuts sparkle and how they look on the hand.
The Round Brilliant: The Icon
There's a reason the Round Brilliant is the most popular diamond shape for over a century. It is the benchmark for brilliance. Its 58 facets have been scientifically perfected to capture, reflect, and return the most light, giving it an unmatched "fire."
-
The Look: A perfect circle of dazzling, balanced sparkle. It’s the "classic" engagement ring shape.
-
The Vibe: Timeless, traditional, and endlessly versatile. It looks perfect in any setting, from a simple solitaire to a glamourous halo.
-
Key Consideration: A well-cut Round Brilliant is a masterpiece of light performance. It sets the standard for all other cuts.
The Oval Cut: The Modern Favourite
The Oval Cut has skyrocketed in popularity, and it's easy to see why. It has all the fire and brilliance of a Round cut but in a soft, elongated shape.
-
The Look: A brilliant, sparkly oval. Its elongated shape has a wonderful "finger-lengthening" effect, making the hand appear slimmer.
-
The Vibe: Elegant, modern, and flattering.
-
Key Consideration: The Oval's shape gives it a larger surface area than a Round of the same carat weight, meaning it often looks bigger. When shopping for an Oval, you'll hear about the "bow-tie" effect—a slight shadow in the centre. A well-cut Oval (which we hand-select) will have a minimal, barely-noticeable bow-tie.
