Several years ago, a diamond of wonderful size and beauty, having wandered from the East, fell into certain imperial coffers among our Continental neighbors; and at the same time some extraordinary intelligence, essential to the existence, so to speak, of that government, reached a person there who fixed as its price this diamond. After a while he obtained it, but, judging that prudence lay in departure, took it to England, where it was purchased for an enormous sum by the Duke of ----, as he will remain an unknown quantity, let us say X. There are probably not a dozen such diamonds in the world,--certainly not three in England. It rejoiced in such flowery appellatives as the Sea of Splendor, the Moon of Milk; and, of course, those who had been scarcely better than jewed out of it were determined to obtain it again at all hazards;--they were never famous for scrupulosity. The Duke of X. was aware of this, and, for a time, the gem had lain idle, its glory muffled in a casket; but finally, on some grand occasion, a few months prior to the period of which I have spoken above, it was determined to set it in the Duchess's coronet. Accordingly, one day, it was given by her son, the Marquis of G., into the hands of their solicitor, who should deliver it to her Grace's jeweller. It lay in a small shagreen case, and, before the Marquis left, the solicitor placed the case in a flat leathern box, where lay a chain of most singular workmanship, the clasp of which was deranged. This chain was very broad, of a style known as the brick-work, but every brick was a tiny gem, set in a delicate filigree linked with the next, and the whole rainbowed lustrousness moving at your will, like the scales of some gorgeous Egyptian serpent:--the solicitor was to take this also to the jeweller. Having laid the box in his private desk, Ulster, his confidential clerk, locked it, while he bowed the Marquis down. Returning immediately, the solicitor took the flat box and drove to the jeweller's. He found the latter so crowded with customers, it being the fashionable hour, as to be unable to attend to him; he, however, took the solicitor into his inner room, a dark fire-proof place, and there quickly deposited the box within a safe, which stood inside another, like a Japanese puzzle, and the solicitor, seeing the doors double-locked and secured, departed; the other promising to attend to the matter on the morrow.
