Provenance

Engraved topaz from the collection of Princess Anna-Maria Radziwiłł (1907-1995), mounted by Boivin for Jeanne-Marie de Broglie

The French maison of Boivin is associated with some of the most original and impeccably crafted jewellery of the 20th century. Founded by René Boivin in 1890, it produced unconventional designs that proved popular with aristocrats, artists and intellectuals, earning Boivin the sobriquet ‘jeweller of the intelligentsia’.

Inspired by distant lands, Art Deco architecture and exotic flora and fauna, its brightest and boldest designs emerged under the direction of René’s widow, Jeanne, who employed the talents of three remarkable designers, including the couple’s daughter, Germaine.

Born in 1864, René Boivin began his career at 17 as an apprentice goldsmith; by 1890, he had distinguished himself sufficiently as a designer and engraver to found his own workshop. Three years later, he married Jeanne Poiret, sister of the renowned couturier Paul Poiret, which introduced him to Parisian high society, and in 1905 he stopped designing for companies such as Mellerio and Boucheron to focus on private clients.

Boivin was one of the first jewellers of his generation to use semi-precious stones, laying the foundations for the company’s style of the 1930s and 1940s. The maison also crafted organic materials such as wood and coral.

The present collection of Jeanne-Marie de Broglie offers a remarkable insight into the later creative period of the House under the artistic direction of Marie-Caroline de Brosses. It includes five lots that perfectly illustrate Boivin’s enduring creativity and technical virtuosity.

Among them, a magnificent necklace, designed in May 1981, combines natural pearls, cultured pearls, an impressive peridot of approximately 57 carats and diamonds in a bold yet harmonious composition.

Equally remarkable is a transformable set, designed in March 1970, comprising a brooch-pendant, a four-row necklace, a two-row choker and a bracelet. At its centre is an engraved topaz bearing the arms of the Radziwiłł family, formerly in the collection of Princess Anna-Maria Radziwiłł (1907-1995), which Boivin mounted especially for Jeanne-Marie de Broglie.

Completing this exceptional group is a striking coral sautoir, designed by Marie-Caroline de Brosses in the 1970s, demonstrating the Maison’s continued fascination with sculptural forms and unconventional materials.

The house of René Boivin finally closed in the 1990s, but its jewels, beautiful, innovative and always ahead of their time, are perhaps more highly prized than ever.
