Cartier Art Deco Sapphire Diamond Stick Pin by Henri Picq

A magnificent Cartier Art Deco stick pin, masterfully executed by the legendary Parisian workshop Henri Picq, Cartier’s foremost manufacturing partner during the early 20th century. Crafted in platinum, the piece displays an elegant tapering silhouette set with a vivid royal-blue sapphire and old European-cut diamonds, meticulously graduated in size for perfect visual harmony.

The precision and artistry evident in this design reflect the distinctive collaboration between Cartier and Henri Picq — a partnership that defined the golden era of French haute joaillerie. The deep sapphire anchors the composition, framed by a constellation of sparkling diamonds that capture the light with striking brilliance.

Bearing the Henri Picq hallmark, this rare jewel represents the pinnacle of Art Deco design and craftsmanship, combining Cartier’s refined aesthetic with Picq’s exceptional technical execution. A piece of historical and artistic importance, it stands as a testament to the enduring legacy of both names.
