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.

Frequently asked questions

Can I see these diamonds in your London store?

Our London store displays finished jewellery and a smaller selection of gemstones. Our loose diamonds are held at our workshop, so they are not on display in store.
