Marquise

A marquise is a brilliant cut drawn out into a long, slim shape with a point at each end. Worn along the finger, it covers more of it than a round of the same carat weight, so it tends to look generous.

It has a lovely vintage feel, with roots in 18th-century France, but in a modern setting it reads striking and fashion-forward. It's for someone who wants a ring that doesn't look like anyone else's.

The points are the most delicate part of the stone, so they're best protected with claws. Symmetry matters here too, as evenly matched tips make all the difference to how the finished ring looks.

FAQ

Does a marquise look bigger than other cuts?

It often does. The marquise has one of the largest surface areas for its weight of any shape, so it can look bigger than a round or princess diamond of the same carat.

Is a marquise practical for everyday wear?

The points sit a little higher than the rest of the stone, so they need a setting that protects them, which ours are designed to do. Looked after, it wears as comfortably as any other shape.
