The diamond shape

Understanding diamond shape

The shape describes the external contour of the diamond, independently of its quality or weight.

Each shape has its own characteristics:

• some maximise brilliance,
• others emphasise an elongated appearance,
• some highlight surface presence,
• while others focus on structure and transparency.

Choosing a shape is primarily a matter of personal sensitivity.

The main diamond shapes

We offer a complete selection of the most sought-after diamond shapes:

• Round Brilliant: the most common shape, known for its balance and its ability to reflect light.
• Oval: an elongated shape offering a generous visual surface and fluid elegance.
• Pear: a slender silhouette combining roundness and finesse.
• Princess: a modern geometric shape with clean, assertive lines.
• Marquise: an elongated and expressive shape, historically associated with classical elegance.
• Radiant: a combination of straight lines and dynamic facets, emphasising reflections.
• Emerald: a structured cut that highlights transparency and depth.
• Cushion: softened contours offering a warm and balanced presence.
• Heart: a symbolic and expressive shape, requiring great cutting precision.

How shape affects visual perception

Shape influences:

• how light circulates within the diamond,
• the perception of its actual size,
• the balance between brilliance, fire and clarity.

At equal carat weight, two diamonds of different shapes can produce very different visual impressions.

Choosing the shape that suits you

There is no universal ideal shape.

The best choice is the one that matches:

• your aesthetic sensitivity,
• the visual effect you are looking for,
• the way you wish to perceive the diamond’s light.

Once the shape is selected, you can continue your search by refining the weight (carat).
