Why choose a marquise cut diamond?

The marquise cut's elongated, boat-like shape with two pointed ends is said to date back to 18th-century France. It has one of the largest surface areas of any diamond shape, so it looks bigger than its carat weight and makes the finger appear longer and slimmer.

How to choose a marquise lab-grown diamond

Symmetry. Both points should line up and both sides should curve evenly. Look for Excellent or Very Good symmetry.

Length-to-width ratio. Classic marquise cuts are around 1.85 to 2.10.

Colour and clarity. D to G gives a bright white look; VS1 and VS2 clarity are eye-clean.

Both points should line up and both sides should curve evenly. Look for Excellent or Very Good symmetry.

Length-to-width ratio

Classic marquise cuts are around 1.85 to 2.10.

Dutch marquise

Dutch marquise cuts have straight, angled sides instead of curved ones, for a more geometric look.

Colour and clarity

Colour can show slightly at the points, so D to G suits a marquise. VS2 and better look clean to the eye, and almost all of ours are VS2 or better. Every stone has a 360° video on its page, so you can see how clean it looks.
