Cartier by Henri Picq 18K Gold Art Deco Ruby Stylized Bird Stick Pin
Art Deco Cartier by Henri Picq 18K Gold Ruby Stick Pin
An exceptionally rare Art Deco stick pin by Cartier, designed by Henri Picq, crafted in 18K gold and set with vibrant rubies in a striking stylized bird motif. Bearing Cartier serial number 1783, along with the Henri Picq maker’s mark and the French eagle head hallmark, this piece represents the highest level of early 20th-century French jewelry craftsmanship.
This remarkable Art Deco stick pin is a refined example of Cartier’s avant-garde design language during the 1920s–1930s, a period defined by bold geometry, abstraction, and technical excellence. The design depicts a stylized bird, rendered through sharp, angular forms and set with richly colored rubies, echoing the modernist spirit that defined the Art Deco movement.
The pin is crafted in 18K gold and bears Cartier serial number 1783, a valuable archival reference that confirms its authenticity and production within Cartier’s historic ateliers. Adding to its exceptional importance, the piece is stamped with the Henri Picq maker’s mark, identifying one of Cartier’s most celebrated master jewelers, renowned for executing some of the firm’s most innovative designs during the early 20th century.
Also present is the French eagle head hallmark, the official assay mark for 18K gold. The combination of Cartier signature, serial number, Henri Picq hallmark, and French eagle head is particularly rare, placing this stick pin firmly in the category of museum-quality Art Deco jewelry.
Beyond its historical significance, the piece is visually striking—its dynamic composition and vivid rubies giving the impression of movement and vitality, qualities highly sought after by collectors of Cartier and Art Deco jewelry alike.

Why This Piece Is Exceptional
Jewelry signed by Cartier and Henri Picq, especially pieces retaining clear serial numbering and original French hallmarks, is increasingly scarce. Stick pins from this period were often lost, altered, or melted, making surviving examples of this quality and documentation particularly rare. This piece stands as both a wearable work of art and a historically significant object from one of Cartier’s most innovative eras.

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.
