Blue Heart Diamond

There is a spectacular diamond in the Smithsonian Collection called Blue Heart Diamond. Fans of the Titanic movie might think "Heart of the Ocean Diamond" is based on this rock, and that's possible! However, this diamond has not been cast in the ocean, but is safe and healthy at the Smithsonian!

This is also called Eugenie Blue Diamond, although it is uncertain that Empress Eugenie once had this special stone. Cut in Paris between 1909 and 1910, but the origin of the stone - Africa or India - is unclear.

This is a very large blue heart shaped diamond weighing 30.82 carats. The current arrangement is a platinum ring, surrounded by white diamonds. It changed hands among famous jewelers - such as Cartier and Van Cleef & Arpels - and the owner until it was bought by Harry Winston in 1959 who put diamonds in the current ring settings. Winston sold the ring to Marjorie Merriweather Post. Mrs. Post donated the ring to the Smithsonian and remained there with other famous blue diamonds, including Hope Diamond and Heart of Eternity Diamond.

This famous blue diamond has recently gone through a process of assessment and ranking, to classify their colors and to determine the source of color. The Hope Diamond is classified as Fancy Deep Greyish-Blue. The Heart of Eternity has been classified as Fancy Vivid Blue. The Blue Heart Diamond has not been classified, but some experts categorize it as Fancy Vivid Blue or Fancy Deep Blue. Blue diamonds are very attractive to scientists not only because of the color and dirt that creates them, but because blue diamonds also have electrically conductive properties that make them unique among clear and other colored diamonds.
