Rare Cartier by Henri Picq Platinum Carved Sapphire Intaglio Stick Pin

A Masterwork of Early 20th-Century Craftsmanship by Cartier’s Renowned Henri Picq

A magnificent and exceedingly rare creation by Henri Picq for Cartier, this platinum stick pin exemplifies the technical mastery and aesthetic sophistication that defined the Maison’s early 20th-century artistry.

At its center rests a carved blue sapphire intaglio, engraved with cuneiform-inspired motifs reminiscent of ancient Mesopotamian script. The engraving captures both mystery and elegance, while the sapphire’s deep translucence radiates an ethereal glow under light.

Meticulously mounted in platinum, the piece showcases Picq’s legendary precision and Cartier’s pioneering embrace of platinum during the Belle Époque era. Henri Picq’s workshop was among Cartier’s most important suppliers, crafting many of the firm’s most intricate platinum jewels between 1900 and 1918.

This rare jewel unites ancient symbolism and modern refinement—a sculptural testament to the collaboration between Cartier and one of its greatest master craftsmen.
