Shape vs. cut

The outline you fall in love with

Shape describes the outline of a diamond seen from above. Cut describes how precisely its facets are arranged. Brilliant shapes, such as round, oval and pear, are designed for maximum sparkle. Step-cut shapes, such as emerald and asscher, have long parallel facets that create calm flashes of light, like a hall of mirrors. Neither is better: it is simply a question of taste.

How to choose a diamond shape

Think about the jewellery she already loves. Clean, classic pieces usually pair with round or oval diamonds. Architectural, minimalist taste suits emerald, asscher or radiant cuts. Romantic, one-of-a-kind personalities often fall for pear, marquise or heart shapes. Then consider the hand: elongated shapes make fingers look longer and slimmer, while round and square shapes feel balanced on every hand.

Brilliant cuts and step cuts

Brilliant cuts use triangular and kite-shaped facets that break light into countless small sparkles. They hide tiny inclusions well and look lively in every light. Step cuts use long rectangular facets arranged like stairs. They show fewer, broader flashes and a mirror-like clarity, so they reveal more of the diamond's interior. That is why step cuts are best in high clarity grades, like the VVS–VS1 diamonds we use.

Which shapes look largest?

Marquise, oval and pear diamonds show the most surface area per carat, followed by emerald and radiant cuts. Round diamonds carry more weight in their depth, so they look slightly smaller per carat, but they reward you with the most brilliance.

Protecting points and corners

Pear, marquise, princess and heart shapes have delicate points. We protect them with V-shaped claws or a fine bezel so the tips stay safe in daily wear.

Our signature: the Dutch Marquise cut

Alongside the classics, we love the Dutch Marquise cut: a geometric interpretation of the marquise with pointed tips and straight, clean sides. It feels architectural and modern, and it is one of the most distinctive shapes you can choose for an engagement ring.

Frequently asked questions

Which diamond shape sparkles the most?

The round brilliant. Its facet pattern is designed to return the maximum amount of light. Oval, cushion and radiant cuts follow closely.

Which shape is the most popular for engagement rings?

Round remains the classic favourite, while oval, emerald and pear shapes have become especially popular in recent years.

Do fancy shapes cost less than round diamonds?

Usually yes. Cutting a round brilliant loses more of the rough crystal, so fancy shapes of the same quality are often more affordable.

Which shape suits short fingers?

Elongated shapes such as oval, pear, marquise and elongated cushion visually lengthen the finger.
