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. [H] The naming of diamonds is an art wherein there may lie fitness as well as unfitness. Historic stones frequently bear the name of their first well-known owner, as for example the "Regent," the "Orloff," the "Braganza," and many others. Again they may bear names indicative of their character as "Austrian Yellow," "Dresden Green," "French Blue," or yet again their names may be purely fanciful. Of this latter class there are numerous examples. The above "Estrella do Sud" is one, the "Koh-i-nûr" is another. When fanciful names are given we hold emphatically that they should always be in the language of the person who bestows it. As a historian we protest against needlessly confusing the already intricate annals of diamonds by giving to American gems fine names fetched from Persia. The largest diamond found in the United States weighed in the rough twenty-three and three fourths carats and rejoices in the appellation of Oninoor (Sea of Light.)
