Paris. Feb. 12.—On the 7th of next month, Constant Polari alias Carrara, the person accused of having stolen the diamonds of the Princess of Orange, will be brought to trial before the Court of Assizes for South Holland. A Dutch journal gives the following curious details relating to this affair:—"A Frenchman named Roumage in 1831, was the person who denounced Carrara as being in possession of the diamonds. This denunciation was made to the Ambassador of the Netherlands at New York where Polari had recently arrived with his mistress Susan Blanche. Roumage had previously informed the custom-house officers in New York, that Polari had introduced into the country a quantity of diamonds without paying the duties, and he was arrested.
Several of the diamonds were found upon him.
Polari, hearing that his mistress had made a revelation, confessed, after much hesitation, that he knew the diamonds belonged to the Princess of Orange, but affirmed, that he was not the person who had stolen them. Susan Blanche also made known that he had buried in the environs of Brussels a pot, containing several objects of value, together with all the gold and silver in which the diamonds had been set. Roumage, in league with Susan Blanche after having betrayed Polari, thought of his own interest. He learnt from this woman, that some of the diamonds were also buried in a wood, near N. York: he went there to draw them from their place of concealment, and embarked for England, followed by his accomplice, after having, at the same time, given over to the Plenipotentiary of the Netherlands a small portion of the articles taken out of the ground, probably to inspire more confidence, and to obtain more easily the reward promised to whoever might discover the authors of the robbery.
Sometime afterwards, Roumage and Susan Blanche were arrested at Liverpool, and the articles seized upon them were given over to the Dutch Consul in that city, who sent them to the Hague, where they were recognized to have formed a part of the diamonds stolen from the Princess of Orange. The Dutch Government also contrived to get possession of the iron pot buried near Brussels, in which all the settings of the diamonds were found, as well as several cameos, and other precious stones. By means of these settings, it was easy to prove to the Government of the United States, that the diamonds seized by the officers there formed a part of those stolen from the Palace of the Prince of Orange and they were given up immediately to the Dutch Agent at New York. Polari had come to Brussels in 1827, having left Lyons in consequence of bankruptcy.
He pretends that when walking in the woods in the month of November, 1827, he saw three persons concealing something in the earth; he went there at night, and thus became possessor of what he afterwards discovered to be the diamonds of the Princess of Orange. Polari is 53 years old, and born at Wick, in the Swiss canton of Tessin. He was formerly a tanner. His features are disagreeable and repelling. It is with the utmost repugnance that he speaks of the robbery, and particularly of the treachery of Susan Blanche."
