Engagement ring trends for 2026 are all about personality and conscious choices. Classic elements are blended with bold, modern expressions – resulting in rings that feel both timeless and contemporary. Here, we review the styles, shapes, and settings that define this year's engagement rings, and how they fit into Coliène's assortment.
Oval Diamonds – Still on Top
The oval shape has steadily grown in popularity in recent years and shows no signs of slowing down. In 2026, the oval is almost on par with the round brilliant in popularity – and at many jewelers, it has already surpassed it.
The oval's popularity is due to several factors: it appears larger than a round diamond of the same carat weight, it provides a flattering, elongating effect on the finger, and it balances classic elegance with a modern expression.
At Coliène: We offer oval diamonds in several of our ring models. Contact us to find out which models are available with an oval stone.

Marquise-shaped Diamonds Make a Comeback
Marquise – an elongated shape with pointed ends – is making a strong comeback in 2026. The shape has existed for centuries but is now experiencing a renaissance among couples who want something distinctive and bold.
The marquise shape creates a dramatic, elongating effect on the finger and often appears larger than its actual carat weight. It is particularly well-suited for solitaire settings.
Note: Coliène currently offers round brilliant and oval diamonds. Contact us if you are interested in other shapes – we can often find solutions.
Minimalist and Dainty – Focus on the Stone
A clear trend is minimalist, dainty rings with very slender bands. Here, the diamond takes center stage, while the thin setting creates a light and subtle expression that feels both modern and timeless.
The slender band enhances the visual presence of the stone and can make it appear larger in relation to the ring. This trend is seen in both classic solitaires and in petite eternity rings, where small diamonds run along the band, creating a discreet yet vibrant play of light.
Coliène will soon offer a selection of solitaire rings and eternity rings with extra slender bands.
Timeless vs. Trendy – Our Advice
Trends offer fantastic inspiration, but at Coliène, we always want to remind you of one important thing: your engagement ring is something you will wear for decades. Our advice is to use trends as a starting point for inspiration, but ultimately choose what feels right for you – not what is most popular right now.
The most timeless choices – such as the round brilliant in a classic solitaire setting, or an oval in an elegant band – will never feel dated. But if a trend truly speaks to you, there's no reason not to follow your heart.
We are happy to help you find the balance between personal and timeless.
