A Guide to Diamond Shapes: Finding the One That's You

Before the 4 Cs, before the setting, there's shape. A diamond's shape (sometimes called its cut outline) is the first thing anyone notices, and it quietly shapes the personality of the entire piece. Here's how the most-loved shapes differ.

Round brilliant

The classic, and for good reason: 57–58 facets engineered for maximum sparkle. Timeless, versatile and the most brilliant return of light. If you want a diamond that simply glitters, start here.

Oval

All the fire of a round, elongated. Ovals flatter the finger, look larger carat-for-carat, and feel both classic and current.

Emerald

Step-cut and architectural, with long, mirror-like flashes rather than sparkle. Understated, sophisticated, and beloved by those who appreciate clarity and line.

Pear

A teardrop — half round, half marquise. Romantic and distinctive, especially in solitaires and pendants.

Cushion, radiant, princess & more

Cushion softens corners for a pillowy, vintage feel; radiant blends brilliance with a rectangular outline; princess is sharp and modern. There's no “best” — only the one that's most you.
