The Eugénie Blue - Notable Diamond

This Titanic-esque vivid blue diamond is 30.82 carats. It’s called the Eugénie Blue because of an old legend that the sparkly stunner originally belonged to Empress Eugénie de Montijo, the wife of Napoleon III. There is no evidence to support this tale, though, so many people prefer to simply call it “The Blue Heart” instead. The gem was cut into its distinctive shape in 1909 or so (some accounts say it was 1910) and was bought by Cartier shortly thereafter. Since then it has bounced around from a wealthy Argentinian woman, Van Cleef and Arpels, a European family, Harry Winston, Marjorie Merriweather Post, and, finally, the Smithsonian, where The Blue Heart has resided since 1964. And although it may look like it inspired the fictional Heart of the Ocean from the 1997 Leonardo DiCaprio epic, it didn’t - the Heart of the Ocean was actually based on the infamous Hope Diamond.
