Diamond Shapes Explained: Round, Oval, Cushion & Emerald

A diamond's shape is the single biggest driver of its personality. The same carat weight can look bright and classic, soft and romantic, or sleek and modern depending on the cut. Here's a quick guide to four of the most popular shapes — and where to see each one.

Round

The most popular shape for a reason. The round brilliant cut is engineered for maximum sparkle, returning more light to the eye than any other shape. It's timeless, versatile, and flatters every setting — the safe-but-never-boring choice.

Oval

All the brilliance of a round, in an elongated silhouette. An oval's stretched outline makes it look larger than a round of the same carat weight and lengthens the finger beautifully on a ring. A favorite for shoppers who want sparkle plus a little extra presence.

Cushion

Soft, romantic, and full of character. The cushion cut blends a square or rectangular shape with gently rounded corners — like a pillow — for a warm, vintage-inspired look with plenty of fire. Ideal if you love a softer, antique feel.

Emerald

Sleek, sophisticated, and understated. Instead of sparkle-maximizing facets, the emerald cut uses long, stepped facets that create a clear, mirror-like “hall of mirrors” effect. It reads as elegant and modern, and tends to look larger per carat thanks to its open table.
