"This matchless gem combines the beautiful color of the sapphire with the prismatic fire and brilliancy of the diamond, and on account of its extraordinary color, great size and other fine qualities it certainly may be called unique, as we may presume there exists no cabinet nor any collection of crown jewels in the world which can boast of the possession of so curious and fine a gem as the one we are now describing, and we expect to be borne out in our opinion by our readers. There are extant historical records and treatises on the precious gems which give us descriptions of all the extraordinary diamonds in the possession of all the crowned heads of Europe as well as of the princes of the Eastern countries. But in vain do we search for any record of a gem which can in point of curiosity, beauty and perfection be compared with this blue brilliant, etc." Mr. Hertz was no doubt a good jeweller and a clever expert, but he was not very learned in the history of precious stones or he could never have made this astonishing statement. He had only to search in the records of France to find the account of a wonderful blue diamond of even greater size. With regard to the value of the diamond, he declares his inability to fix any sum, saying: "There being no precedent the value cannot be established by comparison. The price which was once asked for this diamond was thirty thousand pounds (one hundred and fifty thousand dollars) but we must confess for the above stated reason that it might have been estimated at even a higher sum." There was a precedent for estimating its value; but of that Mr. Hertz was ignorant. The French Blue was valued at three millions of livres (six hundred thousand dollars) when it weighed sixty-seven carats. According to this calculation one hundred and fifty thousand dollars was not an excessive price to put upon the Hope Blue of forty-four carats. The Hope Blue still remains in the possession of the family which has given it that name, while the other fraction of the dissevered French Blue is likewise in private hands. This is much to be regretted from the historian's point of view, for famous diamonds acquire a great deal of their value and all their interest from the persons who have owned them. For a gem which has graced the royal festivities of Versailles as the Blue Diamond has done, or enhanced the stately ceremonials of the Escurial as was the case with the Pelegrina, to sink into obscurity in the collection of a wealthy Mr. Unknown or in the jewel casket of a Princess Nobody is a sad decadence. Jewels, from their value and indestructibleness, are among the few objects used by the illustrious dead which can and do remain unaltered in appearance, therefore it is contrary to our sense of the fitness of things for a historical gem to cease to be such by belonging to a person without a history.
