Boivin
The Maison Boivin was a precursor of its era with an uncompromising style free from fashion trends and conventional designs. Jeanne Boivin, who considered every jewel as a piece of architecture, almost completely abandoned the traditional ring mounts. She designed some of the most iconic rings of the house such as 'Clou', 'Escalier', 'Toit', and 'Bande'. The first 'Bande' ring was created in 1931.
