Diamond shapes

The diamond's shape is the first thing you notice – it sets the tone for the entire ring's character and style. Some shapes maximize brilliance, while others provide an elegant silhouette on the finger. Here, we guide you through the shapes we offer and help you find the one that suits you best.


Form & grind – what’s the difference?

It's common to confuse a diamond's shape with its cut, but they describe two different things. The shape is the diamond's overall outline – round, oval, pear-shaped, and so on. The cut, on the other hand, is about how the facets are placed and how well they reflect light.

A round diamond, for example, can have a "brilliant cut" (with at least 57 facets optimized for maximum light reflection) while another round diamond can have a simpler cut. At Coliène, we work exclusively with the cut grade Excellent, regardless of shape.


Round brilliant

Round brilliant

The round brilliant-cut diamond is the most classic and popular shape in the world. With at least 57 carefully placed facets, it is optimized for maximum light reflection – which gives an impressive brilliance and a beautiful play of light.

The round shape is timeless and versatile. It suits virtually all setting types, from classic solitaires to modern halo rings and elegant eternity bands. If you are unsure which shape to choose, the round brilliant is a safe choice that never goes out of style.


Suited for those who

You want maximum brilliance and a timeless, classic feel. The round brilliant is also the most forgiving choice when it comes to hiding small inclusions and color tones.


Oval

Oval

The oval shape combines the brilliant cut's magnificent play of light with an elegant, elongated silhouette. The oval has grown significantly in popularity in recent years and is now one of the most sought-after choices for engagement rings.

One of the oval's great advantages is that it appears larger than a round diamond of the same carat weight, thanks to its more extended surface area. It also creates a beautiful, flattering effect on the finger – especially for those who desire a slightly more modern and distinct look.


Suitable for those who

Looking for a modern and sophisticated feel with a vibrant play of light. The oval shape creates an elongated, elegant expression and highlights the size of the stone.

The choice of diamond shape ultimately comes down to personal taste and style. Here are a few things to consider when making your selection:
