The Cartier Trinity collection traces its origins to 1924, when Louis Cartier designed a ring composed of three intertwined, freely moving bands. Traditionally rendered in yellow, rose, and white gold, the interlocking design established the distinctive three-part form that remains at the center of the collection today.

Since its introduction, Trinity has expanded beyond the original ring to include bracelets, necklaces, earrings, and other jewelry designs. Across these different forms and variations, the collection continues to explore the interplay of its three interconnected elements through different proportions, materials, and diamond-set interpretations.
