The firm known as René Boivin began in 1890 when René Boivin (1864–1917) opened a jewelry shop with his wife, Jeanne. The sister of couturier Paul Poiret, and herself a designer, Jeanne assumed leadership of the company following her husband's premature death in 1917. For the next forty years, Jeanne Boivin, together with several talented female designers, firmly established the house as one of the most innovative and artistic design forces in Paris. The firm's pieces are distinctive for their varying textures and combinations of materials. The present pendant was originally designed by Juliette Moutard, a talented designer who worked closely with Madame Boivin and her daughter Germaine. See the book Boivin by Françoise Cailles.
