Permission obtained to visit the Diamond Mines.—Account of a pretended Diamond presented to the Prince Regent.—Journey to Villa Rica.
AFTER I had thoroughly recovered from the fatigues of my late journey, I solicited his Royal Highness for permission to go and explore the diamond mines of Cerro do Frio. This favor had never as yet been granted to a foreigner, nor had any Portuguese been permitted to visit the vicinity where the works are situated, except on business relative to them, and even then under restrictions, which rendered it impossible to acquire the means of giving an adequate description of them to the public. Through the kind friendship of the Conde de Linhares, the permission was granted, and my passports and letters of recommendation were speedily made out. Lord Strangford was much pleased at my being so highly favored, and willingly offered his service, and represented me favorably at court. I obtained admission to the archives, for the purpose of examining all the manuscript maps, and of copying from any of them whatever might be necessary to guide me in my route. It may here be proper to observe, that the most eligible mode of travelling in the interior of Brazil, especially on such an excursion as I had undertaken, is to procure orders from the government, and an escort of soldiers, who have a right, under such orders, to require proper relays of mules from all persons who reside on or near the road. The Conde de Linhares intimated to me, that I might select any two soldiers I thought proper, and while I was deliberating on the choice, a singular occurrence took place, which was the means of furnishing me with two men of the corps of miners, who were appointed to attend me, under an injunction on the part of His Excellency, that their future promotion would depend entirely on the report which I should give of their conduct after my return. I am happy to say that their services merited every commendation.
The occurrence to which I allude was this:—A free negro of Villa do Principe, about nine hundred miles distant, had the assurance to write a letter to the Prince Regent, announcing that he possessed an amazingly large diamond which he had received from a deceased friend some years ago, and which he begged he might have the honor to present to His Royal Highness in person. As the magnitude which this poor fellow ascribed to his diamond was such as to raise imagination to its highest pitch, an order was immediately dispatched to the commander of Villa do Principe, to send him forthwith to Rio de Janeiro; he was accommodated with a conveyance, and escorted by two soldiers. As he passed along the road, all who had heard the report hailed him as already honored with a cross of the order of S. Bento, and as sure of being rewarded with the pay of a general of brigade. The soldiers also anticipated great promotion; and all persons envied the fortunate negro. At length, after a journey which occupied about twenty-eight days, he arrived at the capital, and was straightway conveyed to the palace. His happiness was now about to be consummated, in a few moments the hopes which he had for so many years indulged, would be realized, and he should be exalted from a low and obscure condition, to a state of affluence and distinction:—such, no doubt, were the thoughts which agitated him during the moments of suspence. At length he was admitted into the presence; he threw himself at the Prince’s feet, and delivered his wonderful gem. His Highness was astonished at its magnitude; a pause ensued; the attendants waited to hear the Prince’s opinion, and what he said they seconded. A round diamond, nearly a pound in weight, filled them all with wonder; some ready calculators reckoned the millions it was worth; others found it difficult to numerate the sum at which it would be valued, but the general opinion of His Highness’s servants was, that the treasury was many millions of crowns the richer. The noise which this occurrence created among the higher circles, may be easily conceived; the general topic of remark and wonder, was the negro’s offering. It was shewn to the ministers, among whom an apprehension, and even a doubt, was expressed, that a substance so large and round might not prove a real diamond; they, however, sent it to the treasury under a guard, and it was lodged in the deposit of the jewel-room.
On the next day, the Conde de Linhares sent for me, and related all the circumstances which had come to his knowledge respecting this famous jewel, adding, in a low tone of voice, that he had his doubts about its proving a genuine diamond. His Excellency directed me to attend at his office in a few hours, when letters from himself and the other ministers to the Treasury should be given me[33], for permission to see this invaluable gem, in order to determine what it really was. Readily accepting a charge of so interesting a nature, I prepared myself, and attended at the hour appointed, when I received the letters, which I presented at the treasury to an officer in waiting, I was led through several apartments, in which much business seemed to be transacting, to the grand chamber, where presided the treasurer, attended by his secretaries. Having my letters in his hand, he entered into some conversation with me relative to the subject; I was then shewn through other grand apartments hung with scarlet and gold, and ornamented with figures as large as life, representing justice holding the balance. In the inner room, to which we were conducted, there were several strong chests with three locks each, the keys of which were kept by three different officers, who were all required to be present at the opening. One of these chests being unlocked, an elegant little cabinet was taken out, from which the treasurer took the gem, and in great form presented it to me. Its value sunk at the first sight, for before I touched it, I was convinced that it was a rounded piece of crystal. It was above two inches in diameter. On examining it, I told the governor it was not a diamond; and to convince him I took a diamond of five or six carats, and with it cut a very deep nick in the stone. This was proof positive; a certificate was accordingly made out, stating, that it was an inferior substance of little or no value, which I signed.
Other boxes were now unlocked, from one of which they showed me two large slabs of diamond, each a full inch on the superficies, and about the eighth of an inch in thickness, of a very bad brown color. When found, they formed one entire piece, which, being amorphous, was not known to be a diamond, until the administrator or chief of the working party, after keeping it by him many days, had recourse to the old experiment of placing it on a hard stone and striking it with a hammer. The result of this experiment is, that if the substance resist the blow, or, separate in laminæ, it must be a diamond; the latter was the case in the present instance, and the man having thus made two diamonds from one, transmitted them to the intendant.
The river Abaité, from whence these pieces came, has produced one of an octahedral form, which weighs seven-eights of an ounce Troy, and is perhaps the largest diamond in the world. It was found about twelve years ago by three men who were under sentence of banishment for high crimes; but on presenting this valuable gem to the then Viceroy, they were pardoned and rewarded. It is now in the private possession of the Prince Regent.
