French jeweler Boucheron released a Qixi Festival (Chinese Valentine’s Day) campaign highlighting new additions to its Quatre Grosgrain line alongside the Quatre Classique collection. The short film, titled Endless Linkage, uses the Grosgrain motif as a metaphor for enduring personal connections. Introduced in 2004, the Quatre collection combines four archival motifs: Double Godron (1860s), Clou de Paris (1911), Line of Diamonds (1892), and Grosgrain (1860s). The latest Grosgrain pieces extend beyond rings and ear cuffs to include necklaces, bracelets, and stud earrings in yellow or white gold, plus mixed gold-and-diamond designs.
