Cartier made history during the 20th century on several occasions. In 1917, inspired by the speedy Renault tanks developed during World War I, Louis Cartier designed the rectilinear Tank watch. In the 1920s, he created the opulent Patiala Necklace for the grand Maharaja of Patiala, and in the 1940s, a Panthère jewel for the Duchess of Windsor. Wallis Simpson was devoted to Cartier, and Grace Kelly wasn’t exactly resistant—she accepted a 10.47-carat diamond engagement ring from Prince Rainier III. Then came the Cartier Crash in 1967, its surreal curves reminiscent of Salvador Dalí’s melted clocks. This exhibition at the V&A showcases 350 objects, including historic gems, objets d’art, necklaces, bracelets, brooches, and tiaras. —Elena Clavarino
