The necklace 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 weigh, and it weighed 234.65 carats in its final setting. The necklace also contained seven other large diamonds ranging from 18 to 73 carats, and a number of Burmese rubies.
The necklace disappeared from the Royal Treasury of Patiala around 1948.
In 1998, part of the necklace was found at a second-hand jewellery shop in London by Eric Nussbaum, a Cartier associate. The remaining large jewels were missing, including the Burmese rubies and the 18 to 73 carat diamonds that were mounted on a pendant. Cartier purchased the incomplete necklace and, after four years, restored it to resemble the original. They replaced the lost diamonds with cubic zirconia and synthetic diamonds, and mounted a replica of the original "De Beers" diamond.
The necklace is the subject of a documentary by Doc & Film International.
