Louis Cartier (1875?1942), the grandson of Cartier founder Louis-François, was an impassioned collector and patron of the arts. He was particularly entranced by Islamic arts, especially Persian book arts: their geometric shapes, color combinations, and motifs are apparent in Cartier jewelry to this day. Louis?s younger brother Jacques?an expert in precious stones?traveled to India and the Persian Gulf in 1911 and 1912 to experience the culture and bring home treasures of the Middle East: natural pearls. This was the pivotal moment when the dialogue between these two worlds opened up, eventually blossoming into a beautiful relationship that has lasted for decades.Cartier and Islamic Arts
