Are Diamonds Dated? In London, Milan, and CPH, Chic People Are Wearing This Understated Stone Instead

By Swedan MargenDecember 17, 2025

Wait, are diamonds dated? The obvious answer is no, and that's largely still true. We are, however, starting to see the rise of an alternative stone that the best dressed women on our feeds are styling all their latest outfits with instead of pieces that incorporate diamonds. Everyday diamonds like diamond studs can still be seen on fashion people, but when it comes to what they're styling their holiday-party looks with, it's none other than onyx jewelry.

The style set in cities like London, Milan, and Copenhagen tend to set trends, and right now, it seems like everyone is adopting onyx stones into their wardrobes. It's thanks in no small part to It-girl brands like Le Sundial, Juju Vera, Sophie Buhai, and Agmes, who are all designing onyx pieces that have an art deco feel, which is a jewelry trend we're noting will be big for 2026. Below, see how chic people are styling onyx jewelry now, from cool cuffs to Gwyneth Paltrow's viral tassel necklace, and shop the best outfit-making versions we love.

While diamonds are traditionally the go-to stone for a dressed-up moment during the holidays, fashion people are wearing moody onyx pieces with their dresses and skirts instead this festive season.

Beaded jewelry has been having a major moment all year, and the most forward dressers are choosing beaded styles featuring onyx stones. Le Sundial's Tina Necklace, seen here on Elly McGaw, is an insider favorite.
