Cartier Art Deco Platinum Emerald and Diamond Stick Pin by Henri Picq

Art Deco Cartier Emerald and Diamond Stick Pin 

A magnificent Art Deco creation, this platinum stick pin exemplifies the refined geometry and impeccable craftsmanship of Cartier’s golden era. The design centers on a vibrant row of five step-cut emeralds—each displaying a deep, verdant hue—framed by two rows of old European-cut diamonds that shimmer with elegant precision. The crisp, architectural symmetry reflects the height of 1920s Art Deco sophistication.

This exceptional jewel bears the hallmark of Henri Picq, one of Cartier’s most esteemed master craftsmen, whose Paris workshop produced many of the Maison’s finest creations. Picq’s signature attention to detail is evident in the flawless stone setting, intricate milgrain edging, and the harmonious balance between the brilliance of diamonds and the rich color of emeralds.

A true collector’s piece, this stick pin is not only a symbol of luxury but also a rare artifact of Cartier’s historic collaboration with Henri Picq—where artistry, precision, and timeless beauty converged.
