PROVENANCE : SUZANNE THE LITTLE SISTER OF THE THREE GREAT CARTIERS Cartier jewellery was to make a splash in the world of jewellery, starting with a generation formed by Louis who ran Paris, Jacques in London and Pierre who opened the New York branch. Not forgetting their younger sister, Suzanne, who married into the family of the great couturier Worth. She was 22 when she married Jacques Worth, and her wedding witnesses were none other than her brother Louis, married to Andrée-Caroline Worth (the groom's cousin), and her brother-in-law Jacques Lemoine, married to the groom's sister, René Worth. Great ideas were established based on strong links in the luxury sector between these genius entrepreneurs and craftsmen. At the time, Worth was much larger than Cartier. Little sister Suzanne, who became Mrs Worth, was not part of the great adventure. In the third photo, you will find a full-length portrait of his daughter Hélène Worth, luxuriously dressed for her debutante ball, initiating her life in the café society of the time, from which some of the pieces come. The watches and objects we are presenting were entrusted to us directly by her grandson. Francesca Brickell-Cartier's book reveals family details confirmed by descendants.
