Diamond Shapes: A Guide for Engagement Rings

A diamond's shape sets the character of the whole ring. Here are the main shapes — modern and antique — and what each one offers.
Round brilliant
The most popular and most sparkling shape. In antique rings, its forerunners are the old European cut and old mine cut, which glow more softly.
Cushion & old cuts
The cushion cut — a soft-cornered square — descends from antique cuts and suits vintage-style rings. Romantic and full of character.
Emerald & asscher (step cuts)
The emerald cut (rectangular) and asscher cut (square) are step cuts with broad, elegant flashes — hallmarks of Art Deco rings.
Marquise, oval & pear
The marquise (pointed oval), oval and pear shapes lengthen the finger and look larger for their weight — elegant, distinctive choices.
Which shape should you choose?
Round and cushion are classic; emerald and asscher are sophisticated; marquise, oval and pear are striking. Match the shape to your partner's taste and browse diamond engagement rings.
