The Mystery Necklace 2025 by Cartier fuses art and engineering into a transformable design, symbolic of the maison’s innovative spirit and elegance.
Where mystery and mechanics meet: Here is the latest marvel of Cartier Haute Joaillerie-the Transformable Mystery Necklace. Drawing on the very heart of Cartier’s “mystery clock” concept, this creation takes the art of illusion to new heights.

Fashioned in white gold, set with diamonds and blue sapphires, the necklace boasts a centre stone that seemingly levitates without visible support, while a delicate mechanism allows the ornate neck piece to transform easily into a shorter collar or pendant necklace.

Cartier tempers technical brilliance with aesthetic sophistication, not allowing the mystery to ever take precedence over beauty. Each curve, each facet, speaks to centuries of craftsmanship honed for the modern collector. It’s a piece that really reflects the maison’s mantra: elegance that evolves with you.

Worn by royalty, celebrities, and patrons of high art alike, the Mystery Necklace is a reminder that the most captivating luxury is that which retains a hint of secrecy.
