Cartier’s Kashmir blue takes the lead in a Rockefeller group at Christie’s New York on 10 December 2025: a 17.66-carat unheated Kashmir sapphire ring, an Art Deco emerald bracelet, Raymond Yard parrots, and a 1950s Cartier watch—where provenance and design excellence meet in a resonant constellation.
Three jewels of imperial provenance take centre stage at Sotheby’s Royal & Noble Jewels Sale in Geneva: Napoleon’s diamond brooch seized at Waterloo, Cunegonde of Saxony’s pearl Sévigné, and Princess Neslishah Sultan’s pink diamond ring — each a reflection of history’s splendour and legacy.
In the wake of the Louvre heist, one jewel stands out among the treasures stolen — Empress Eugénie’s Reliquary Brooch. Crafted by Bapst in 1855 and set with Louis XIV’s legendary Mazarin diamonds, it carried within its 94 stones the luminous history of France’s monarchy. Its loss marks the disappearance of a national treasure once believed to be forever safe.
Recovered after the Louvre heist, Empress Eugénie’s 1855 crown — set with 1,354 diamonds and 56 emeralds — has escaped the robbery but bears visible damage. Now in secure hands, it awaits expert restoration before returning to the Galerie d’Apollon.
In a meticulously planned daylight raid, thieves broke into the Louvre’s Galerie d’Apollon and fled with jewels of “inestimable heritage value.” One damaged piece, believed to belong to Empress Eugénie, has since been recovered.
