Oval vs Round vs Cushion Diamond Engagement Rings

Many engagement rings come down to a choice between three shapes. Each has its own character, and none is better in every way.

Round

The round brilliant is the classic. It is cut to return as much light as possible, so it usually sparkles the most. It is the most common shape for solitaires and is easy to set. Because demand is high and more rough is lost in cutting, a round diamond usually costs more per carat than the other two. See what is a round brilliant cut diamond?.

Best for: those who want maximum sparkle and a classic look.

Oval

An oval is an elongated round. It has strong brilliance and its long outline makes the finger look longer and slimmer. For the same weight, it often looks larger than a round, because the weight is spread along a longer shape. Look out for a "bow-tie", a dark band across the middle visible in some ovals, and choose a stone without a strong one.

Best for: those who want a modern look, a larger appearance for the weight and a flattering shape on the finger.

Cushion

A cushion is softly square with rounded corners. It has a romantic, slightly vintage look. Cushions can be cut in different ways: some show bold, chunky facets and others sparkle more like a brilliant. They sit well in halo and three-stone settings. The rounded corners make them practical for daily wear.

Best for: those who want a soft, vintage-inspired look.

Comparison at a glance

| | Round | Oval | Cushion | |---|---|---|---| | Sparkle | Highest | High | High, depends on cut | | Looks larger for weight | Average | Often larger | Average | | Price per carat | Usually highest | Usually lower | Usually lower | | Durability | Very good | Very good | Very good | | Style | Classic | Modern | Vintage |

In words: round has the most sparkle and usually the highest price per carat. Oval often looks larger for its weight and costs less. Cushion has a soft, vintage look and sits well in halos.

Durability

All three have no sharp corners, so they resist chipping better than pointed shapes. See are diamonds unbreakable?.

Which suits your hand?

Long, slim fingers suit almost any shape. Shorter fingers often look elegant with an oval, which lengthens the line. Wider fingers can carry a larger cushion or round with ease. The best test is to try them on.

Price and value

You can use shape to stretch a budget. An oval or cushion of a given quality typically costs less per carat than a round, so you may afford a larger stone. See engagement ring budget: how much should you spend?.

What to check in each

• Round: cut grade, polish and symmetry.
• Oval: bow-tie, symmetry of the outline.
• Cushion: the style of facets, and how it sparkles in person.
