The Nawanagar Ruby Necklace, commissioned in 1937 by Maharaja Digvijaysinhji Jadeja of Nawanagar, India, is a stunning example of Indo-European jewellery design. Crafted by Cartier, it features 116 Burmese rubies weighing nearly 170 carats, surrounded by exquisite diamonds set in platinum. This royal heirloom reflects the opulence of princely India while embracing the sophistication of European craftsmanship. After India's Independence, the necklace was returned to Cartier for resale, undergoing modifications yet retaining its historical significance. Its global fame soared in 1966 when it was worn by Gloria Guinness at Truman Capote's iconic Black and White Ball, marking its transition into the realm of high fashion. Currently, it resides in the Al Thani Collection, celebrated for preserving rare jewels. The necklace was also prominently displayed at the 'Magnificent Mughals to Maharajas' exhibition at the Grand Palais, captivating audiences with its brilliance and historical allure.
