The sculptural allure of the Trinity line
Imagined by Louis Cartier in 1924, the Trinity collection established itself as an absolute signature of Parisian jewellery. Initially designed without gemstones to highlight the purity of precious metal, it embodied a radical aesthetic for its time. This classic 18-carat gold model intertwines white gold, yellow gold and rose gold. Produced during the sought-after "Les Must de Cartier" period, this pre-owned ring bears the number O 9023 Z. Its refined allure is built on rigorous geometric proportions.
Jewellery architecture and craftsmanship
The technical mastery of this piece lies in the mobile interlacing of 3 independent bands. Each ring body adopts a half-round profile offering ergonomic contact. The classic model stands out with a width of 3.4 millimetres per band. The absence of setting demands polishing of surgical regularity to reveal the distinct colour of each alloy. The substantial mounting reflects the very generous casting standards of the Maison’s workshops during that period.

Choosing the pre-owned market allows one to benefit from a generous gold structure at a competitive position compared with contemporary editions.
