At the declaration of peace between England and Spain in 1604 King James gave the Spanish Ambassador, the Duke de Frias, Constable of Castile, who negotiated the treaty, a large diamond ring, in commemoration of the _marriage_, as he called the peace. Charles the Bold, Duke of Burgundy, had a large diamond cut by Berghem into a triangle, which he had set in a ring representing two clasped hands, the symbol of good faith, and sent to Louis XI., ‘an allusion’ (remarks the Rev. C. W. King), ‘though in an acceptable form, to his deficiency in that virtue.’ An anecdote connected with the celebrated ‘Pitt’ diamond is related by Mr. Eastwick, and shows how important results may sometimes be secured, when reason and logic may not prevail. This jewel passed through some curious adventures, and, after having ornamented the sword of Napoleon at Waterloo, was sent as a present in a ring by George IV. to the Sovereign of Persia, Fath-Ali-Shah. The bearer of this costly ring, Sir Harford Jones, was stopped in his journey by a messenger from the court, and desired not to enter the capital, where French interests were then paramount. After Sir Harford had exhausted every argument to show that he ought to be received, without making any impression on the Persian Khan, he said, ‘Well, if it must be so, I shall return, but this must go with me,’ and he took from his pocket the beautiful diamond ring which had been sent for the Shah. The sparkle of the gem produced a magical effect; the Khan no sooner beheld it than he lost his balance, and fell back from his seat quite out of breath; then, recovering himself, he shouted, ‘Stop, stop, Elchi! May your condescending kindness go on increasing! This alters the matter. I will send an express to the heavenly-resembling threshold of the asylum of the world! I swear by your head that you will be received with all honour. Mashallah! it is not everyone that has diamonds like the Inglis.’ He was as good as his word; the express courier was despatched, and Sir Harford Jones entered the city of Teheran by one gate, while General Gardanne, the French envoy, was packed off by the other. [This stone must have been a fraction or portion of the cutting of this famous diamond, as the ‘Regent’ is still in the French _Garde-meuble_, or national treasury.] In 1514 Venice deputed two ambassadors to France and England; amongst other _bribes_, two rings were ordered to be given privily to the French Secretary, Robertet, ‘as a mark of love in the Signory’s name.’ One had a ruby and a diamond.
