Diamond Shape Guide
The shape of a diamond changes how it sparkles, how large it looks and how it sits on the hand. Here is how the most popular shapes compare.
Round brilliant
The most popular shape, cut to return the most light. Timeless and suited to every setting.
Oval
An elongated round with similar brilliance. Ovals look larger for their carat weight and lengthen the finger.
Pear
Round at one end and pointed at the other, like a teardrop. Elegant and distinctive, flattering on the hand.
Emerald
A rectangular step cut with long, clean facets that create a hall-of-mirrors effect. Sophisticated and architectural.
Cushion
A square or rectangle with softly rounded corners, combining vintage romance with strong sparkle.
Princess
A square shape with pointed corners and brilliant faceting. Modern, crisp and full of fire.
Marquise
A long shape with pointed ends that maximises carat weight and makes the finger look slender.
Heart
The ultimate romantic shape. Best in larger sizes, where the heart outline is clear.
