Anatomy of the Oval Diamond

Core Features and Proportions

The oval diamond is essentially an elongated version of the round brilliant cut, combining brilliance with a more distinctive silhouette.

• Its soft, rounded ends mimic the marquise shape—but without sharp points

• Ideal length-to-width ratio: 1.33 to 1.50 for a balanced, elegant look

• Typically has 57 facets, slightly fewer than round diamonds (58), which alters how light reflects

This subtle difference in faceting creates a unique light pattern, giving ovals a softer, more spread-out brilliance compared to rounds.

The Bow-Tie Effect Explained

One defining feature of oval diamonds is the bow-tie effect—a dark shadow that appears across the center of the stone.

• Caused by improper light reflection due to poor cut

• More noticeable in poorly proportioned stones

Actionable Tip: Always choose diamonds with Excellent or Very Good symmetry grading from trusted labs like Gemological Institute of America to minimize this effect.

• A 1-carat oval can look similar in size to a 1.25-carat round diamond

• The elongated shape maximizes surface area (table coverage)

This makes oval diamonds a top choice for buyers who want maximum visual impact without increasing budget.
