Diamond Shapes for Engagement Rings

The diamond shape refers to the outline of a diamond when viewed from above, and it's one of the biggest style decisions in choosing an engagement ring. The most popular shapes are round, oval, princess, cushion, pear, marquise, emerald, and radiant, each offering a different balance of brilliance, silhouette, and personality.

Round remains the most popular by far, holding 60 to 70 percent of the US engagement ring market, but oval, cushion, and radiant cuts have grown fastest in recent years for their modern look and larger visual size per carat.

Diamond Shape vs. Diamond Cut: What's the Difference

Diamond shape and diamond cut are often used interchangeably, but they mean different things. Shape is the outline of the stone, such as round, oval, or emerald. Cut refers to the proportions, symmetry, and faceting that determine how well a diamond reflects light. A diamond's shape shows first; its cut determines how much it sparkles.
