RENÉ BOIVIN: A COLLECTIBLE 'GROSEILLES' CULTURED PEARL RINGOf bombé design, set with graduated cultured pearls, each punctuated with dot gold detailing, mounted in 18K gold, signed René Boivin, with maker's mark 'Sté RB' for René Boivin, French assay mark, with maker's case, ring size I½ (Probably a design from Juliette Moutard, later reinterpreted by Marie-Caroline)A similar ring is illustrated, page 388, 'René Boivin, Paris', by Francoise Cailles, éditions de l'Amateur.René Boivin (1864–1917) began his jewellery career at seventeen, following his elder brother Victor’s footsteps by working first as a goldsmith’s apprentice and taking drawing lessons at a local art school. Having refined his skills in several workshops, he soon earned a reputation as a talented draughtsman, designer and engraver. By 1890, René was ready to start his own enterprise. He acquired his first workshop in Paris, equipping it with all the necessary tools and skilled craftsmen. A few years later, he moved to new premises on the rue de Turbigo and married Jeanne Poirot, sister of the esteemed French fashion designer Paul Poiret. The firm’s reputation grew rapidly by word of mouth, thanks to its meticulously crafted pieces and commissions from jewellers such as Mellerio and Boucheron. Though proficient in both modern and classical design, René developed a keen interest in naturalism; his solid background in botany led him to create life-like floral motifs. While Art Nouveau’s flowing curves were fashionable at the time, the Boivin workshop chose a more unconventional path to appeal to a more discerning clientele. Boivin’s wife Jeanne had already been deeply involved in the business, and after René’s untimely death in 1917, she took full control of Maison Boivin. Though she had not planned a career in jewellery, she quickly adapted to managing both the creative and financial aspects of the business. Jeanne not only upheld René’s legacy, but she also steered the firm through challenging post-war years, leading a workshop of around twenty artisans and establishing it as the only major jewellery house of its time run by women. Jeanne possessed a keen eye for talent. In 1919, she recruited Suzanne Vuillerme, later known as Suzanne Belperron, a new graduate from the Besançon Beaux-Arts Academy. Belperron’s innovative use of coloured stones, texture, and predominantly 18K yellow gold set her work apart from the prevailing Art Nouveau and Art Deco styles. Her collaboration with Jeanne brought renewed energy to the firm throughout the 1920s. In 1931, Belperron left to form a partnership with Bernard Herz, paving the way for Juliette Moutard to join the firm. Moutard was an experienced designer having worked at Verger Frères and designed for Cartier and Van Cleef & Arpels. She began her long-standing association with Maison Boivin in 1933. Under Jeanne’s guidance, Juliette flourished. She introduced bold, imaginative designs that embraced organic, feminine lines over rigid Art Deco forms. Jeanne further recognised Juliette’s talent by entrusting her with drawing duties for both herself and her daughter Germaine, who had recently joined the business. The close collaboration between Jeanne, Germaine, and Juliette created a unified creative force, often making it hard to pinpoint the origin of any single design. The firm’s approach was as distinctive as its jewellery. Clients were rarely given cost estimates or delivery dates, and customer gemstones or design ideas were only accepted for particularly significant patrons, such as the Duchess of Windsor and Millicent Rogers. Madame Boivin was so confident in her workshop’s output that she famously declared, “my style is my signature”, believing the pieces spoke for themselves. Many clients appreciated this unconventional method, knowing each design was unique, with few repeats and even fewer exact copies. Juliette Moutard dedicated her entire career to Maison Boivin, remaining at the firm even after Madame Boivin retired in 1954 and passed away five years later, leaving Germaine in charge. Together, Moutard and Germaine maintained the firm’s creative integrity and commitment to originality. Moutard retired in 1970 but stayed connected to the firm until her death in 1990. The family sold the jewellery house to their diamond supplier Mr. Perrier, and in 1967 Jacques Bernard took over, with a former Cartier workshop manager later assuming ownership. The 1980s brought revived interest in the Boivin Maison, first led by Marie-Caroline de Brosses and subsequently by Sylvie Vilein. The introduction of fresh, new creations that remained true to the Boivin style, attracting clients such as Hélène Rochas and the Aga Khan. The Asprey Group, acquired the firm before Nathalie Choay purchased it in 1999 to preserve its heritage and archives. Now overseen by Thomas Torroni-Levene, these documents will form the basis of a definitive book scheduled for publication this year, one that aims to record the complete history of René Boivin and highlight the contributions of each designer along the way. Condition Report:Cultured pearls: of white/cream tint with pink and green overtones, very good lustreSignature located inside mount, on the upper side of the galleryEagle's head for French 18K gold & maker's mark for René Boivin, 'RB with snake'Normal signs of wear, overall in good conditionTotal gross weight approx. 29.5g

A VINTAGE MARKED SILVER ART DECO MARCASITE AND AMETHYST RING SIZE N IN A PRESENTATION BOX

Cartier: A 5.08 carat diamond single-stone ring circa 1925 Set with a cut cornered, step-cut diamond, weighing 5.08 carats, in a four-claw setting, signed Cartier, numbered, ring size PAccompanied a later Cartier case as well as a Letter of Expertise from IAJA Expertise stating that the ring is a genuine Cartier New York item from circa 1925. Letter numbered XP2197-290125, dated 29th January 2025.The diamond has been assessed unmounted by GCS and a verbal result given that the diamond is L colour, VS1 clarity. It is rarely discussed in jewellery history who actually cut the diamonds and gemstones which find themselves adoring fabulous jewels. The role of the lapidary is even further removed from the limelight than that of the goldsmith.However one name in diamond cutting has managed to carve out a well deserved reputation. The Amsterdam based firm of I J Asscher Diamond Company has cut some of the most famous diamonds in history, including the 3,106 carat Cullinan Diamond.Founded in 1854 by Joseph Asscher, its global headquarters are still located on the original site Tolstraat 127, Amsterdam, The Netherlands. In 1904 they patented a cut of diamond unlike anything else at the time. The Asscher-cut is almost square and was composed of 50 or 58 facets. The geometric style meant that it perfectly suited the Art Deco jewels made in the coming decades.Asscher was well known to be a preferred diamond supplier to Cartier. A diamond of similar appearance to this one, appears central in the Patiala necklace made by Cartier in 1928.Sadly a large amount of the Asscher firm’s archives was lost in the Nazi occupation during WWII. Like the vast majority of other diamonds, it is not possible to know for sure who cut this particular diamond but the style and angular facet arrangement are indicative of the firm’s output.
