Signed and dated 7 February 2022 It is ironic that René Boivin is a name well known in the jewellery world, as his life is relatively unknown. It is also interesting to note that René Boivin did not always craft the pieces that bear his name. Boivin was born in Paris in 1864. He began his career in jewellery at a young age and, by the time he died in 1917, had become a highly skilled designer and engraver, leaving behind him a legacy of excellence in jewellery. During the 1890s, he purchased several workshops, establishing himself at rue St. Anastase, then relocating in 1893 to Rue de Turbigo. He married Jeanne Poiret, the first woman jeweller of the 20th century (sister of the famous couturier, Paul Poiret) and together they created some of the most exciting and bold fashions of the early 1900s. In the early 20th century Japanese art and antiques were very much en vogue and, as Boivin had a passion for antiques, it is no surprise that this trend influenced his own jewellery designs. His skill as a goldsmith can be appreciated from beautifully finished pieces and his interest in animals and nature inferred through jewellery themes. After René’s death, Jeanne assumed control of the business and moved to avenue de I’Opera with Juliette Moutard and her daughter Germaine Boivin. They worked together for forty years, joined by Suzanne Belperron between 1921 and 1932. After Jeanne’s death in 1959 the house was taken over by Louis Girard and in April 1991 the company became part of Aspery Group, with the main office and store located on avenue Montaigne.
