The Antwerp artists having accomplished their task to the satisfaction of Louis XVI., "he rewarded with presents, magnificent and really worthy of a King of France, all those who had a hand in it." The Blue Diamond came forth from the hands of the cutter an irregularly-shaped brilliant of a drop form weighing sixty-seven and one half carats.
In 1791, it was entered in the inventory of the Crown Jewels, which was drawn up by order of the Constituent Assembly, at the high valuation of six hundred thousand dollars. It will be thus seen that it had enormously increased in value since its "rough" days, for then the Blue Diamond as well as all the other diamonds and precious stuffs were bought from Tavernier for that precise amount.
"BRUNSWICK" BLUE DIAMOND.
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."
As a notable gem in a famous private collection the Hope Blue enjoyed for years a quiet distinction. It was set round about with pearls and white diamonds to enhance its azure and had a beautiful pearl-drop for pendant. Altogether it was a neat and delightful trinket; price one hundred and fifty thousand dollars. Little or nothing was thought about it until the death of the Duke of Brunswick, the mad diamond-miser who used to sleep surrounded with mechanical pistols which were warranted to go off with such fatal facility that it is a marvel they did not shoot his Grace in mistake for a burglar. In 1874, the Brunswick diamonds came to the hammer and amongst them a blue stone of six carats weight. Mr. Streeter, than whom there exists no better authority on diamonds, had this stone and the Hope Blue put into his hands together. He found that they were identical in color and quality, that the sides of cleavage matched as nearly as could be determined after the cutting, while the united weights plus the calculated less from re-cutting amounted to the weight of the French Blue. He immediately drew the very natural conclusion that both these stones were once united and formed the Blue Diamond brought from India by Tavernier. He, it will be remembered, called it of a "lovely violet" and as only very few other blue diamonds are known to be in existence, and they are all of a pale blue tint, we must admit that the weight of evidence hangs strongly in favor of Mr. Streeter's reasoning.
"HOPE BLUE" DIAMOND, AS MOUNTED.
The collection of the late Mr. Hope was a very large and valuable one. Of course the blue diamond was its chief glory, but it contained other gems of value. A portion of these were recently offered for sale consisting of diamonds, sapphires, opals and pearls, set and unset, and of rings, crosses and bracelets, of all sorts of shapes and patterns. The display reminded one of a jeweller's show-case except for this remarkable difference. There were no two objects alike, and all showed the refined taste of an amateur rather than the massive showiness of the mere commercial jewel.
