Cartier was founded in Paris in 1847 by Louis-François Cartier. His three grandsons, Louis, Pierre, and Jacques, built the house into a famous international jewelry empire serving royalty, Hollywood stars, and socialites. Cartier has created some of the most important jewelry and objects of art of the twentieth century with many iconic designs such as mystery clocks, Tutti Frutti jewelry and the Panthère line. In 1983, The Cartier Collection was established with the objective of acquiring important pieces that trace the firm's artistic evolution. Today, Cartier has 200 stores in 125 countries.
