Diamonds are found in various parts of the globe. The most celebrated diamond regions are those of India, South Africa, and Brazil. The Indian diamond mines are in various localities, the most famous being in the vicinity of Golconda. They have been exploited for thousands of years, and some of the stones now in existence have a history dating back two thousand years before the Christian era. The diamond mines of Brazil have latterly yielded more extensively than have the Golconda mines. At one time, a slave at work in a Brazilian mine struck with his pick a bed of diamonds which were valued at nearly two millions of dollars. They were carried to England, and caused a panic in the diamond market. The supply was the largest ever known to come forward at one time, and greatly frightened the holders of precious stones, not only in England, but all over the continent of Europe. If any individual could be so fortunate as to find a few million dollars’ worth of diamonds at one time, he could create an alarm among the dealers in precious stones from one end of the world to the other. The work of obtaining diamonds is not by any means the easiest in which a man can engage. About the hardest way in the world to obtain gold is to dig for it, and the same may be said of diamonds. In the Brazilian mines the earth consists of sand and gravel in the beds of the streams. It is taken out in the dry season, and piled away where it can be conveniently washed. Then in the rainy season the washing begins. Sometimes the men work by hand, as it were; that is, by taking a quantity of earth in a bowl, or pan, and then, standing in the middle of the stream, under the eye of a vigilant overseer, they slowly wash away the sand and dirt, until nothing but pebbles remains. [Sidenote: DIGGERS AT WORK.] The pick and shovel are used for breaking up the diamond-bearing gravels, just as they are used for breaking up earth which contains gold. The water carries away the clay, and sand, and fine dirt. The large stones are thrown out, and the finer gravel that remains is carefully picked over. It is examined in the sunshine, where the light plays upon the gems, and leads to their detection. The search for the diamond is always conducted under the eye of a superintendent, so as to guard against theft. Each diamond-seeker has a little case, made of reed, and generally ornamented on the outside. The small diamonds are placed in this case, and every negro who possesses a case which has once held diamonds is very unwilling to part with it. He regards it with a superstitious reverence, believing that when it once contains precious stones it will lead to the discovery of more.
