Quick answer: Round diamonds offer the most classic, maximum sparkle, while oval diamonds look larger for the same carat weight and flatter the finger with an elegant, elongated shape. Both are timeless — it comes down to the look you love.

The round brilliant

The round brilliant is the most popular diamond shape for good reason: its cut is engineered to return the most light, giving unrivalled sparkle. It suits every setting, from solitaire to halo.

The oval cut

An oval is a brilliant cut too, so it sparkles beautifully, but its elongated outline makes it appear larger than a round of the same carat weight and can make the finger look longer and slimmer.
