Rare Lacloche Frères Art Deco Platinum Fancy-Cut Diamond Airplane Stick Pin
Lucien Girard for Lacloche Frères: An Art Deco Aviation Jewel
A rare and imaginative Art Deco airplane stick pin by Lucien Girard for Lacloche Frères, finely crafted in platinum and set with an exceptional arrangement of fancy-cut diamonds. Conceived as a miniature aircraft, the jewel captures the fascination with aviation, speed and technological progress that defined the Art Deco era.
Rather than relying on conventional round diamonds, the design incorporates carefully selected baguette, rectangular and triangular-cut diamonds to construct the wings, fuselage and tail of the airplane. Each diamond was cut and positioned as an architectural component of the design, producing a crisp geometric silhouette with remarkable precision and visual balance.
The cool brilliance of the platinum setting allows the diamonds to remain the principal focus while preserving the clean, streamlined character of the aircraft. The result is both sophisticated and playful—a technically accomplished jewel that transforms one of the great symbols of early modernity into a highly collectible work of wearable art.
The stick pin is signed Lacloche Frères and bears a serial number, a French platinum hallmark and an additional maker’s hallmark believed to be associated with Lucien Girard. These identifying marks contribute to the historical importance of the jewel and provide valuable evidence of its French manufacture and distinguished origin.

Collector’s Note
Aviation motifs became powerful symbols of modernity during the Art Deco period, reflecting an era captivated by engineering, movement and the possibility of flight. Jewelers translated this enthusiasm into streamlined objects that combined technical precision with imaginative design.
This airplane stick pin is especially compelling because the fancy-cut diamonds do not merely decorate the jewel—they form the structure of the aircraft itself. The combination of a signed French maison, platinum construction, distinctive diamond cutting and an identifiable maker’s hallmark gives the piece considerable appeal for collectors of Lacloche Frères jewelry, French Art Deco design and rare aviation-themed jewels.
The association with Lucien Girard adds another important dimension. Girard is recognized for his work connected with Lacloche Frères, and the additional hallmark may help further document the workshop responsible for this exceptional miniature jewel. Until the maker’s mark is conclusively researched, the attribution should be presented as believed to be associated with Lucien Girard, rather than stated as an absolute fact.

How do I know a piece is authentic, and can I trust DSF?
Buying fine jewelry online takes trust, especially at this level. DSF Antique Jewelry is a New York–based dealer with over 50 years of fine jewelry expertise. Every piece is examined for authenticity and condition before it is listed — we assess hallmarks, maker's marks, metal content, gemstones, and construction consistent with the stated period or designer. For signed pieces such as Cartier, Buccellati, or Van Cleef & Arpels, we verify maker's marks and signatures. We're glad to send additional photographs of any hallmark, or speak with you directly, before you decide.
Why does antique gold look different, and is surface wear normal?
Antique pieces were often made in gold standards less common today, such as 15ct (used in Britain only between 1854 and 1932), 9ct, or higher-karat continental gold, which give a warmer tone than typical modern 14k. Light surface wear, softened edges, and a gentle patina are normal and expected on antique jewelry — they reflect the age and authenticity of the piece, not flaws. We describe the true condition of every item honestly in its listing.
What do the hallmarks and maker's marks mean?
Hallmarks are small stamped marks that identify the metal standard, and often the maker, assay office, and date. They are one of the best tools for authenticating antique jewelry. We identify and explain the marks we find on each piece in its description, and we're happy to send close-up photographs of any hallmark on request so you can see exactly what you're buying.
Can pieces be resized or adjusted?
It depends on the piece. Many antique rings can be resized, but bands with all-around engraving, thin shanks, or gemstones near the base may be limited in how far they can safely go, and some pieces are best left as-is to preserve their integrity. We list each item's measurements as they currently are. If you're unsure whether something can be safely adjusted, contact us before buying and we'll give you an honest assessment for that specific piece.
How should I care for and store fine jewelry?
Clean gently with a soft cloth, avoid harsh chemicals, ultrasonic cleaners, and chlorine, and store pieces separately so they don't scratch one another. Remove rings and bracelets for heavy manual tasks. Antique gold is softer than modern alloys, so period pieces are best enjoyed with normal care. Treated well, fine antique jewelry lasts for generations — many of our pieces are already a century or more old and still beautiful.
