"Jeweller of Kings and King of Jewellers" was how King Edward VII dubbed the house, half a century after Louis-Francois Cartier founded what would become the world's largest jeweller in 1847.
It was certainly to Cartier that the Maharaja of Patiala turned when he travelled to France early last century from India's Punjab laden with treasure.
"He arrived in Paris in 1928 with chests packed full of antique jewels and asked Cartier to rework them in a modern style," the curator of the Cartier collection Pascale Lepeu told AFP.
The show running until February 16 under the famous glass roof of the Grand Palais exhibition hall is the largest ever devoted to Cartier.

With items dating from the 19th century to the 1970s, it highlights the styles that influenced the house over the years, from Marie-Antoinette to the Art Deco movement, to Russian, Indian and Chinese trends.
Most of the 600 pieces on show belong to the house, which decided in the mid-1980s to start buying back historic pieces, at auction or from antique dealers.
Others are high-profile loans, including from Queen Elizabeth II who made available the tiara Cartier created in 1936 for the British royal family, which the queen lent to Prince William's bride for their wedding last year.
Known as the "Halo" and set with 739 brilliant and 149 baton diamonds, it was bought by George VI before his coronation for the Duchess of York, now the Queen Mother, who presented it to Elizabeth on her 18th birthday.
Also on loan from the queen, an exceptional 23.6 carat pink diamond, gifted to Elizabeth for her wedding and set into a flower-shaped brooch by Cartier.
"These are the essence of Cartier," Lepeu said. The first was created in 1912, at a time when it took a year to build just one.
