In order to encourage honesty among the slaves, the finders of large diamonds were rewarded in different degrees according to the size of the stone. The finder of an octavo (seventeen and one half carats) was crowned with a wreath of flowers and carried in procession to the administrator who gave him his freedom and two new suits of clothes. The fortunate negro, moreover, then received permission to work in the mines on his own account.
During Mawe's stay at Tejuco a negro found a very large diamond, which with much eagerness he took to be weighed.
"It was pleasing to see the anxious desire of the officers that it might prove heavy enough to entitle the poor negro to his freedom, and when on being delivered and weighed it proved only one carat short of the requisite weight all seemed to sympathize in his disappointment."
Even now after all these years one cannot help feeling regret for the high hopes of that humble slave so sadly blighted. But those who build their fortunes on diamonds are sometimes bitterly disappointed. Harken to this anecdote from the pen of the same traveler in Brazil. He was waiting for an escort to the mines and had meditated taking a couple of soldiers, when a singular occurrence furnished him with two miners who were appointed to attend him, and whose conduct he pleasantly says deserved every commendation. A free negro from Villa do Principe, some mine hundred miles from Rio Janeiro, wrote to the Prince Regent that he had in his possession an amazingly large diamond which had been bequeathed to him by a friend. The negro was desirous of personally offering it to the Prince whose fondness for diamonds was pretty well known. The Prince commanded the negro to come to the capital immediately, and as the recognized owner of an immense diamond must not travel meanly, he had a carriage and escort given to him. After twenty-eight days of traveling, during which time he was the envied of all beholders, he arrived at Rio Janeiro and was straightway brought to the palace and speedily thereafter into the presence of the Regent. His Highness, well accustomed to large gems, since he used to wear the Braganza around his neck, was nevertheless astonished at the size of this new diamond. Everybody stood with bated breath to hear what he would say, while a few clever ones estimated its value in unheard-of millions. A round diamond was of itself an almost miraculous thing, nobody having ever heard of the like before.
However, it was sent under guard to the treasury, and the next day Mawe was invited to inspect the great novelty and to give his opinion upon it as a geologist. Armed with letters and permits the distinguished stranger went to the treasury and was solemnly introduced into its innermost recesses. He was politely received by the treasurer who explained everything to him, showing him the jewel-chests each fitted with three locks, the three keys of which were held by three different officials.
"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 about an inch and a half 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."
Then the geologist went home and wrote a letter setting forth this unwelcome fact as delicately as he could, for he knew that his letter would be shown to His Highness, and it is at all times an uncomfortable task to tell disagreeable news to a king. However the Prince Regent was high-minded enough not to be angry with him. But great was the disappointment of the unlucky negro. For years he had been building hopes upon that round diamond, and now to see them vanish before the geologist's "deep nick" was trying indeed. Instead of being fêted and feasted and loaded with rewards, he returned home unescorted and empty-handed to be possibly laughed at by those very persons who had formerly envied him.
As a set-off to the deep disappointment suffered on account of this supposed diamond we may mention the finding of another South American stone which was attended with far different results. A negress working at the mines of Minas-Geraes in 1853 picked up in her trough a stone two hundred and fifty-four and one half carats in weight, which proving to be an undoubted diamond obtained freedom for the woman, and afterwards a life-pension. Her master sold the diamond for fifteen thousand dollars, and the buyer immediately obtained one hundred and fifty thousand dollars for it. After being cut by Voorsanger, the same workman who manipulated the Koh-i-nûr, it proved to be a white stone of uncommon beauty and lustre. Under the name of the Estrella do Sud[H] (Star of the South) it attracted much attention from amateurs and was eventually bought by an Indian rajah for one hundred and forty thousand dollars.
Notwithstanding the lofty attitude of judicial impartiality which we endeavored to assume at the beginning of this article, a lurking suspicion remains in our mind that had the Braganza, like the round stone before described, been subjected to the keen scrutiny of Mawe's scientific eyes, it would no longer be classed among the most remarkable diamonds of Europe.
