Patiala Necklace

The Patiala Necklace was a necklace designed and made by Cartier in 1928. It was part of the largest single order ever placed with Cartier to date, made in 1925 by the Indian royal Bhupinder Singh, the Maharaja of Patiala, for the Patiala Necklace and other jewellery worth ₹1,000 million (equivalent to ₹210 billion, US$2.5 billion or €2.2 billion in 2023).

The necklace had five chains (ladi) and included a neck collar. It contained 2,930 diamonds, including as its centrepiece the world's seventh-largest diamond at the time, the De Beers. That diamond had a 428-carat pre-cut weight, and it weighed 234.65 carats in its final setting. It is the largest cushion-cut yellow diamond and the second-largest yellow faceted diamond in the world. The necklace also contained seven other large diamonds ranging from 18 to 73 carats, and a number of Burmese rubies.
