Oyster enthusiasts, this is your moment.\r\nThe largest known freshwater pearl in the world, dubbed \u201cThe Sleeping Lion,\u201d is hitting the auction block on May 31. Weighing almost 4 ounces and stretching over 2.7 inches long, the rare natural object will be sold at the Venduehuis auction house in The Hague, according to\u00a0CNN.\u00a0Top estimates value the pearl, which is being auctioned for the\u00a0first time\u00a0in 240 years, at $632,000.\r\nIn addition to its unique shape, it has a storied history. The outlet reports that the pearl was likely formed between 1700 and 1760, with origins in China. Initially owned by a wealthy trader of the Dutch East India Company, it ended up in his possession after Dutch merchants moved it from China to present-day Jakarta, then Europe.\u00a0CNN\u00a0notes this likely went against Chinese Emperor Qianlong\u2019s ban on large pearl exports, but it ended up in Amsterdam nonetheless, where it was first auction in 1778 following the merchant\u2019s death. It went on to join the collection of Empress of Russia, Catherine the Great, and has been in the possession of various European jewelry through the centuries.
