The shape of a diamond changes the whole look of a piece, even more than its size. Here is a quick guide to the nine most popular diamond shapes, how they look, and who they suit. Every shape below is available in our lab grown diamond collection.
The most sparkling shape of all, with 57 facets cut to return the most light. Timeless, works with every setting, and the safest choice if you are buying a surprise. See the round solitaire ring.
Brilliant like a round, but elongated, so it looks larger for its carat weight and makes fingers look slimmer. One of the fastest-growing engagement ring shapes worldwide.
A teardrop: rounded on one side and pointed on the other. Graceful and unusual, and stunning as a pendant as well as a ring. See the pear cut solitaire ring.
A square shape with sharp corners and lots of sparkle. Modern, clean and bold. See the princess cut ring.
A rectangle with long, step-cut facets that create a "hall of mirrors" effect rather than glitter. Elegant and vintage. Because the facets are open, clarity matters more with this shape. See the emerald cut ring.
A square or slightly rectangular shape with soft, rounded corners, like a pillow. Romantic and full of fire. See the cushion cut ring or the cushion halo ring.
A long shape with two pointed ends. It has the largest surface of any shape for its weight, so it looks dramatic and big. See the marquise cut ring.
The most romantic shape, a perfect choice for an anniversary or a gift. Best at 1 ct and above, where the heart outline is clear. See the heart cut ring and the heart cut pendant.
A square step cut with cut corners, like an emerald cut in square form. Art-deco, geometric and very distinctive. See the Asscher cut ring.

Round is still the most popular, followed by oval, which has grown quickly in recent years.
