The passage discusses Cartier's Panthère de Cartier jewelry collection which celebrates its 100th anniversary. It traces the origins of the panther motif back to 1918 when Jeanne Toussaint, Cartier's artistic director, was nicknamed "La Panthère" and first featured the panther on a vanity case. The panther became one of Cartier's most popular motifs, adorning the jewelry of famous clients. The new anniversary collection features over 50 pieces combining traditional gemstone settings with geometric panther shapes in bold designs that can take over a year to create.
