The Jewellery Trend: Mixed Metals

Cartier's Trinity ring is the original proof of concept: three interlocking bands in yellow, white and rose gold that made mixing metals feel intentional rather than accidental. Designed in 1924 for the French poet Jean Cocteau, it set a precedent that fine jewellery has been building on ever since. The ring continues to be reimagined today, appearing in new configurations and finishes that keep it feeling current.

The idea gained further credibility through watchmaking – Rolex's two-tone Rolesor pieces normalised steel and gold as a marker of status. Brands like Boucheron followed suit, and the look became a mainstay of the jewellery zeitgeist. Its Quatre – four bands, three colours of gold, each one referencing a different chapter of the Maison's archive – turned mixed metals into something you could build and personalise rather than simply wear.
