Cartier New York Art Deco Sapphire and Diamond Platinum Stick Pin

Cartier Art Deco Sapphire and Diamond Stick Pin

An exceptional Cartier New York Art Deco stick pin, crafted in platinum and set with alternating old European-cut diamonds and calibré-cut sapphires in a perfectly graduated, tapering design. The precision of the mounting — where each stone fits seamlessly within its platinum channel — exemplifies the architectural harmony and geometric sophistication for which Cartier was celebrated during the 1920s.

The intense royal-blue sapphires contrast vividly with the brilliance of the diamonds, creating a dynamic interplay of light and color. Sleek, refined, and impeccably balanced, this design captures the modern elegance of the Jazz Age — an era defined by innovation, glamour, and style.

Engraved “Cartier N.Y.” on the reverse, this rare jewel reflects the distinctive craftsmanship of Cartier’s American workshops, renowned for their technical excellence and forward-thinking aesthetic. Originally designed as a gentleman’s accessory, it stands today as a superb example of Cartier’s Art Deco mastery and timeless artistry.
