214 THE GREAT DIAMONDS OF THE WORLD.
was cut after coming into the possession of the French king, and reduced to 67 1/8 carats is most probable. It appears that by cleavage subsequently the dia­mond was reduced to 44 1/4 carats, and after this treatment it came into the possession of the late Mr. Henry Thomas Hope, and stands unrivalled.
The disappearance of Tavernier's rough blue from the French regalia, followed by the unexplained appearance of a cut gem of precisely the same delicate blue tint, and answering in size to the original after due allowance made for loss in cutting, leaves little or no room for doubting the identity of the two stones. Hence the theory set forth in Precious Stones and Gems remains unchallenged; nor is it likely to be seriously called in question by any future experts. It will be further demonstrated in our account of the " Hope " diamond. We have also succeeded, by a careful process of analysis, in identifying this stone with the French " Blue." It thus appears that the rough un­cut Tavernier, the French " Blue," lost in 1792, and the " Hope," are one and the same stone.
