The Cartier Juste un Clou collection originated in the 1970s from a design by Aldo Cipullo, transforming the familiar form of a nail into a piece of jewelry. Its curved profile, defined head, and pointed end established the distinctive visual language that continues to characterize the collection.

Since its introduction, Juste un Clou has expanded beyond the original bracelet to include rings, necklaces, earrings, and additional bracelet variations. Across these different forms, the collection continues to reinterpret the nail motif through clean lines, polished precious metals, and diamond-set variations while preserving its recognizable silhouette.
