Cartier Art Deco by Henri Picq Emerald and Diamond Stick Pin

Cartier Platinum Emerald and Diamond Stick Pin

A magnificent creation from the Art Deco era, this Cartier stick pin—crafted by Henri Picq, Cartier’s renowned Parisian workshop—embodies the refined geometry and elegance of 1920s design. Set in platinum, the pin features a striking tapering arrangement of vibrant square-cut emeralds alternating with old European-cut diamonds. The crisp contrast between the verdant green and the icy brilliance of diamonds reflects the sophistication and precision that defined Cartier’s golden age.

Bearing Henri Picq’s distinctive “HP” maker’s mark, this jewel exemplifies the collaboration that produced some of Cartier’s most iconic works. Both collectible and wearable, it’s a perfect representation of the house’s dedication to symmetry, proportion, and enduring beauty.
