The Blue Heart - Famous Diamond

Some reports refer to this unusual diamond as the "Eugenie Blue" although it is now recognized that there is no evidence of its having been owned by the Empress. Had she owned it, wouldn't she have chosen to flee with it rather than the diamond which is named after her? However, a French link does exist because the cutting firm of Atanik Ekyanan of Neuilly, Paris cut this heart shape, which weighs 30.82 metric carats and is of a rare deep blue color, sometime between 1909 and 1910. This date raises the question whether the rough stone came from Africa or India.
Another photo of the stone, this time in its platinum ring surrounded by25 white diamonds. The photo at the top of the page of the stone out of its setting is the only one I have seen, which leads me to believe that it was put back into the ring setting sometime after the photo was taken. In 1910 Cartier purchased the diamond and sold it to an Argentinian woman named Mrs. Unzue. At the time, it was set in a lily-of-the-valley corsage and remained so until Van Cleef & Arpels bought the gem in 1953. They exhibited it set in a pendant to a necklace valued at $300,000 and sold it to a European titled family. In 1959 Harry Winston acquired the gem, selling it five years later, mounted in a ring, to Marjorie Merriweather Post. Finally Mrs. Post donated to the Blue Heart to the Smithsonian Institution in Washington D.C. where it

remains to this day.

Three of the world's most famous blue diamonds. Left to right: The Heart of Eternity,the Hope, and the Blue Heart Diamond; 27, 45 and 30 carats, respectively. The Hope looks larger than 45 carats because it is a rather flat stone. The Heart of Eternity is Fancy Vivid Blue, the Hope is Fancy Deep Grayish-Blue and the Blue Heart's color grade is still unknown. (Probably Fancy Vivid or Fancy Deep.)
