In the story of "the Regent" an account was given of the robbery of the Garde Meuble in September, 1792, when the French jewels were stolen. The Blue Diamond shared the fate of all the rest. It was stolen, but unfortunately it was not found in that mysterious Allée des Veuves where the Regent lay hidden. In fact, Tavernier's Blue Diamond, weighing sixty-seven carats, never again re-appeared as such. Men had something else to think of in France besides diamonds during the forty years which followed the great robbery, so that the very existence of a blue diamond was pretty nearly forgotten. True that John Mane, a fairly reliable authority on diamonds, says that "There is at this time (1813) a superlatively fine blue diamond of above forty-four carats in the possession of an individual in London which may be considered as matchless and of course of arbitrary value." This is a most important statement, and in the light of subsequent investigations it would point almost conclusively to the fact that the French Blue, already metamorphosed, was in alien hands, except for the fact that the same writer a little further on makes the announcement of a Blue Diamond, weight sixty-seven carats, being amongst the Crown Jewels of France at the same moment. However this may be, suddenly, in 1830, the small world of diamond-worshipers was startled by the appearance in the market of a unique stone. A deep blue diamond, forty-four and one fourth carats, which Mr. Daniel Eliason had for sale and about which he could give no details. It sprang suddenly upon the world without a history, unless indeed it be the same as that mentioned by Mane some eighteen years before--and yet it was a cut and polished brilliant. Its form was irregular, for it had one very flat side. Mr. Henry Philip Hope bought it for ninety thousand dollars; and it henceforward became known as the "Hope Blue."
