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.
