The brilliance of diamond cuts: The most popular cuts of 2026 and how to choose the right one

The cut of a diamond largely determines how intensely it sparkles. Even with the same carat weight, two diamonds can appear completely different depending on their cut. Clear trends are emerging for 2026: elegant lines, modern shapes, and maximum brilliance will be the focus.

Here you will find a detailed analysis of the most popular diamond cuts for the upcoming season:

1. Brilliant – A timeless classic with maximum sparkle

The round brilliant cut remains the undisputed favorite. With its 58 facets, it offers the highest light reflection and is the ideal choice for classic engagement rings as well as jewelry pieces that are meant to impress with their durability and brilliance in everyday life.

2. Oval – Slim, elegant and modern

The oval cut is the trendsetter for 2026. Its elongated shape visually stretches the fingers and often makes the stone appear larger than its pure carat weight would suggest.

3. Radiant – Modern and intense

The radiant cut combines the clean lines of the emerald shape with the fire of the brilliant. It is the perfect choice for those seeking a modern look with extremely high brilliance.

4. Emerald – The elegance of clarity

The emerald cut emphasizes the purity of the diamond. Its long facets create an elegant "mirror effect" that perfectly matches the current silent luxury trend .

5. Princess – Dynamic and square

The princess cut, with its sharp angles and edges, has a particularly youthful and modern look. It is a perfect match for contemporary, architectural ring settings.

6. Pear & Marquise – The optical extenders

The pear cut (pear shape) in particular will experience a major comeback in 2026. It lends a feminine touch to every piece of jewelry and is perfectly suited for elegant vintage designs.
