"The King of Lahore having heard that the King of Cabul possessed a diamond that had belonged to the Great Mogul, the largest and purest known, he invited the fortunate owner to his court, and there, having him in his power, demanded his diamond. The guest, however, had provided himself against such a contingency with a perfect imitation of the coveted jewel. After some show of resistance, he reluctantly acceded to the wishes of his powerful host. The delight of Runjeet was extreme, but of short duration,--the lapidary to whom he gave orders to mount his new acquisition pronouncing it to be merely a bit of crystal. The mortification and rage of the despot were unbounded. He immediately caused the palace of the King of Cabul to be invested, and ransacked from top to bottom. But for a long while all search was vain; at last a slave betrayed the secret;--the diamond was found concealed beneath a heap of ashes. Runjeet Singh had it set in an armlet, between two diamonds, each the size of a sparrow's egg." The _Shah of Persia_, presented to the Emperor Nicholas by the Persian monarch, is a very beautiful stone, irregularly shaped. Its weight is eighty-six carats, and its water and lustre are superb. The various stories attached to the _Sancy_ diamond, the next in point of value, would occupy many pages. During four centuries it has been accumulating romantic circumstances, until it is now very difficult to give its true narrative. If Charles the Bold, the last Duke of Burgundy, ever wore it suspended round his neck, he sported a magnificent jewel. If the Curate of Montagny bought it for a crown of a soldier who picked it up after the defeat of Granson, not knowing its value, the soldier was unconsciously cheated by the Curate. If a citizen of Berne got it out of the Curate's fingers for three crowns, he was a shrewd knave. De Barante says, that in 1492 (Columbus was then about making land in this hemisphere) this diamond was sold in Lucerne for five thousand ducats. After that, all sorts of incidents are related to have befallen it. Here is one of them.--Henry IV. was once in a strait for money. The Sieur de Sancy (who gave his name to the gem) wished to send the monarch his diamond, that he might raise funds upon it from the Jews of Metz. A trusty servant sets off with it, to brave the perils of travel, by no means slight in those rough days, and is told, in case of danger from brigands, to swallow the precious trust. The messenger is found dead on the road, and is buried by peasants. De Sancy, impatient that his man does not arrive, seeks for his body, takes it from the ground where it is buried, opens it, and recovers his gem! In some way not now known, Louis XV. got the diamond into his possession, and wore it at his coronation. In 1789, it disappeared from the crown-treasures, and no trace of it was discovered till 1830, when it was offered for sale by a merchant in Paris. Count Demidoff had a lawsuit over it in 1832; and as
