Most expensive jewellery pieces around the world

Recently, when Nita Ambani gifted Shloka Mehta, when she became a part of the Ambani family, she chose a gorgeous necklace the L’Incomparable Diamond Necklace by Lebanese jeweller Mouawad. The necklace made headlines for reportedly being the most valuable necklace in the world. It features the largest internally flawless diamond in the world, and cost a whopping USD 55 million (nearly INR 450 crores approx) undoubtedly making it one of the most expensive pieces in the world. It features a flawless 407.48-carat yellow diamond pendant along with a 229.52 carat white diamond necklace, and is intertwined by 18-karat rose gold branchlets. The rose gold chain is adorned with 91 other diamonds, adding another 200 carats to the necklace.
However, reports suggest that Shloka’s necklace was displayed at Sotheby’s in 2022, with some changes made to the diamonds. The diamond was re-cut to improve its shape and increase its depth and lustre and due to this, the weight of the necklace has been reduced to 104.38 carats. At the same time, the yellow coloured diamond has been changed to 303.10 carats as well. But the necklace still maintains its prestige.
Be it the Kohinoor, a rare variety of a pink diamond or a piece of heirloom jewellery passed on over generations, the appeal of fine jewellery is emotional and intrinsically interconnected with the notion of social status. A valuable piece with a hefty price tag is often considered a keepsake.

In light of that, below we’ve listed the most expensive jewellery pieces that exist around the world.
