The hardest known mineral in the world, and at the same time the most valuable, is the diamond. It cannot be cut or scratched by any other substance. In cutting the diamond, another diamond, or the dust of one, must be used. The process of polishing these stones by rubbing two of them together was probably known in Asia a great many years ago; but it was not introduced into Europe until the middle of the fifteenth century. The diamond-cutters of Asia preserved the secret of their work very carefully long after these valuable stones were brought to Europe. About the middle of the fifteenth century, Louis Berquen, of Bruges, accidentally discovered that by rubbing two diamonds together, their surfaces might be cut. The powder obtained in this way is used for polishing the stone.

The diamond must first be dug from the earth, and if we only knew where to find them we could doubtless discover richer gems than any of those now known. The earth which contains the diamond is worked in the same way as the auriferous gravels, both having been produced by the same causes. Gold occurs in the beds or streams, by the disintegration of the rocks, in which it was originally contained, and their gradual wearing and washing away. Diamonds were originally contained in the rocks in the same way that gold was held there, and the process of disintegration has been pretty much thesame. Many of the places where gold is found contained diamonds; and in some localities in California the sands are now being reworked to obtain any small particles of gold that may have been left, and also to obtain diamonds. The original gold-seeker looked only for the yellow metal. The gold-seeker of to-day searches not only for gold, but for hard pebbles, which may prove rough diamonds.

WHERE DIAMONDS ARE FOUND.

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 vigilantoverseer, they slowly wash away the sand and dirt, until nothing but pebbles remains.

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.

The earth which has been gathered up for washing, if it is not worked immediately, is placed under a long shed, and when the rainy season begins, and water becomes abundant, the slaves are assembled for their duty. In the diamond district of Brazil the sheds are generally about thirty yards long, and half as wide. They consist simply of upright posts, and a thatched roof, erected over the spot where the heaps of gravel are placed. A stream of water is conducted through this shed. There is a range of sloping troughs, each about three feet wide, connecting with the streams at the upper end. Opposite the troughs there are high chairs, where the overseers are stationed.

A slave at each trough takes about a bushel or so of the gravel, and lets the water in slowly, in order to wash away the gravel and earthy particles. Then he throws out the largest stones, and examines the rest, with great care, for diamonds. Whenever he finds one, he stands upright, clasps his hands, holding the stone between his thumb and finger, and shows it to the overseer, who receives it.

When a slave finds a stone exceeding seventeen and a half carats in weight, he is immediately set at liberty. Free papers are given him, and he cannot again be enslaved. Generally, on such occasions, a holiday or half-holiday is granted to the negroes about the establishment. The lucky finder is carried on the shoulders of his comrades, and when the day ends most of them are in a condition the reverse of sober.

DISCOVERY IN BRAZIL.

In the diamond district of Brazil the diamonds were first discovered by gold miners, about the year 1730. At first they were ignorant of the value of the gems, and threw them away as useless. Some of the stones were sent to the governor of Brazil as curiosities. He supposed that they were crystals, and by accident a few were carried to Lisbon, where they happened to be shown to the Dutch consul. The consul was a diamond sharp, and recognized the true character of the stones. He immediately caused them to be sent to Holland, where they were cut, and found to be of great value.

As soon as the character of the stone became generally known, large quantities of them were gathered and sent from Brazil, and at one time it seemed as if the diamond market would be ruined. The Portuguese government took means to secure a monopoly of the trade. The diamond district was surrounded by well-defined boundaries, which were guarded with the greatest care. No one was permitted to cross them without a permit from the superintendent of the mine, and whenever a traveller who had visited the diamond ground was leaving it, he was obliged to submit to a thorough examination of himself and baggage. So great was the vigilance, that, it is said, at one time every traveller leaving the district was detained three days at the boundary, and was compelled to swallow medicines whose effect was to prevent his absconding with any precious stones concealed in his stomach.

A peculiar system was established for the regulation of this district. Stringent laws were passed to provide for the registering of the inhabitants, the admission of settlers, and the punishment of infringements of every kind upon the governmentmonopoly. At first the diamond mines were rented to private individuals; but so many frauds were practised, that the government took the matter into its own hands, and worked the mines under officers of its own appointment. At present the mines are open to anybody who chooses to work them, on payment of a tax, which is placed not on the amount of diamonds obtained, but on the number of men employed. This method of collecting the tax is much more successful than the old one of levying a royalty upon the diamonds. The number of men employed can be readily counted, while, the diamonds being small, they could easily be secreted, and the payment of the proper tax evaded.

THE GOLCONDA MINES.

In Asia the most noted localities for obtaining diamonds are in various parts of India and the Island of Borneo. Two thousand years ago the mines of Golconda were the richest on the globe; but for some time they have been comparatively unproductive.

WORKING A DIAMOND CLAIM IN BRAZIL.

RIVER WASHING—CRADLING FOR DIAMONDS.

The working of these mines is carried on very nearly in the same way as the working of the mines of Brazil. In the Brazilian mines the slaves and overseers are permitted to wear clothing, though the slaves are allowed but a very small quantity. Formerly they were compelled to work naked, to prevent their secreting diamonds. At the present time the garments they wear are subjected to the most careful examination. In the mines of India the laborers work entirely nude; but the temperature is such that they do not suffer on account of the absence of clothing. In spite of every precaution they manage to steal diamonds. They secrete them in the hair, unless their hair is cut very short. They push them into their noses, and hide them in various parts of their bodies, and in other ways.

In one of the mines of Borneo there was once a laborer who managed to steal several valuable diamonds. As he wore no clothing when at work, and underwent the usual examination, he was considered entirely safe. He escaped with his prizes, became a rich man, lived contented, and died happy. In his old age he revealed the secret of his diamond thefts.

INGENIOUS MODE OF STEALING.

He had prepared himself for the work with the assistance of a surgeon, who shared with him the proceeds of the enterprise. The surgeon placed a ball, somewhat larger than a pea, in the fleshy part of the man’s thigh; kept down the irritation as much as possible, and allowed the flesh to grow over the wound, or nearly so. The ball was then taken out, leaving a comfortable cavity a quarter of an inch below the skin. A small opening was made, and the skin at the opening was allowed to grow around a steel rod about half as large as the diameter of the cavity. In this way a very fine receptacle was formed for the deposit of the diamond.

It took some time to get it up, but when finished it was entirely satisfactory, and the man was sure of having his pocket always about him. When he found a diamond that could be crowded into this cavity, he would manage to stow it away; and then, at the earliest opportunity, he repaired to the office of the surgeon, where the diamond was removed with the aid of a pair of forceps. They did not strike for the largest diamonds, and were doubtless more successful in this mode of working than if they had planned their enterprise on a grander scale.

It is a general principle in chemistry, that when the component parts of an article are well known, a counterfeit can be produced, provided the component parts are attainable. But it is not so with the diamond.

For hundreds of years chemists have labored to produce this stone. They know perfectly well of what it is composed, but they cannot repeat it. The diamond is nothing more than pure crystallized carbon, and placed under a great heat it boils and disappears. It is not acted upon by acids or alkalies, and when kept in the open air, it may be heated to a high degree without damage. Exposed to the intense heat produced by a Bunsen burner, it is converted into coke; and if it is heated in the open air, it boils at the temperature of melting silver, and disappears in the form of carbonic acid gas. If the sun’s rays are converged to a focus by means of a lens, and directed upon a diamond under a bell-glass filled with oxygen gas, thediamond will burn; and when it is consumed, carbonic acid will be found beneath the glass. Thus the most precious substance in the known world can be made to disappear.

HOW TO KNOW THE VALUE OF DIAMONDS.

The diamond is sold by its weight, estimated in carats,—a carat being equal to three and one fourth grains Troy, and subdivided into half, quarter, eighth, and so on. It is difficult to say what a rough diamond is worth, since a great many reasons may occur to cause its fluctuation in value. The ordinary estimate for a cut diamond is sixty dollars a carat, that is to say, when the stone weighs a single carat. The price of the diamond exceeding a carat is not in proportion to its weight, but by the square of the weight, that is to say, to the weight multiplied by itself. Thus, if a diamond weighing one carat is worth sixty dollars, one which weighs two carats is worth 2 × 2, and then multiplied by sixty, or two hundred and forty dollars. A stone of three carats is worth 3 × 3, multiplied by sixty, or five hundred and forty dollars. The value, therefore, of a polished diamond is found by multiplying the square of the weight by the price of a stone of one carat. This is the rule generally given for the pricing of diamonds; but the value of each stone varies more or less according to its character, so that one stone weighing fifteen carats might be worth three or four thousand dollars more than another stone of the same weight. The best rule, probably, for obtaining the price of diamonds, is to ask a man who has them for sale. Diamonds are sold very much like any other commodity, that is, for the highest price the purchaser is willing to pay.

Diamonds, especially those of a large size, require, it is needless to say, great care in keeping, to save them from being stolen. The crown jewels of England are kept in the Tower of London in an iron cage surrounded with glass. Some of them are of great antiquity. The crown jewels include not only diamonds, but some valuable rubies, sapphires, emeralds, and pearls. The crown contains a heart-shaped ruby, which is said to have been given to Edward the Black Prince by Don Pedro, King of Castile, after the battle of Najera, A. D. 1367.

FAMOUS STONES.

It was afterwards worn in the helmet of Henry V., at the battle of Agincourt, in the year 1415.

The crown jewels of France disappeared in 1792, during the troubles of the first republic, though they were kept under seal, and in the royal treasury. Some of them were afterwards found buried in an obscure place, which was named in an anonymous letter sent to the prime minister. The famous Regent diamond was in this casket.

The Regent diamond is probably the finest and best cut stone in the world, though it is not the largest. It was named after the Duke of Orleans, who was regent during the minority of Louis XV. The regent bought it, in 1717, for one hundred and thirty-five thousand pounds sterling. It was sold to him by Governor Pitt, who paid twelve thousand five hundred pounds for it in India five years before. Its weight before cutting was four hundred and ten carats, and the process of cutting occupied two years. Its weight was reduced to one hundred and thirty-six carats, and its present value is estimated at a million dollars.

Pitt was an unhappy man during the five years he owned the stone. He carried it with him constantly. He never made known his movements a day beforehand, nor slept for two nights successively in the same house.

Another diamond, quite famous in its way, is the “Sancy.” It fell from the helmet of Charles the Bold at the battle of Granson, and was picked up by a Swiss soldier. The soldier disposed of it for two francs, and thought he had made a very good bargain. In 1589 it was bought by De Sancy, treasurer to Henry IV. of France. In 1792 it was stolen, and after various adventures, was bought, forty years afterwards, by Prince Demidoff, who paid for it seventy-five thousand pounds. It has since been sold for a much smaller sum.

A few years ago a diamond was found in Brazil, and imported into France under the name of the Star of the South. It was found by a negress, and bought for a few dollars by a speculator, who obtained a large return for his investment. Its weight in the rough was two hundred and fifty-four carats; after cutting, it was one hundred and twenty-four carats.

Another famous stone, known as the Grand Duke of Tuscany, is of a yellow color, and weighs one hundred and forty carats.

It was lost at one time, and bought subsequently, it is said, for a few francs, out of a jeweller’s shop at Florence, the jeweller supposing that it was only a piece of colored crystal.

THE ORLOFF AND THE KOHINOOR.

A famous diamond in Russia is the Orloff. It is shaped like an egg, with an indented hollow in the smaller end. It was found at Landak, in India, and at one time formed the eye of an idol in a Brahmin temple at Pondicherry. An enterprising deserter from the French army managed to have himself shut up in the temple, and during his incarceration he gouged out this eye of the idol. He attempted to capture the other eye, but was unsuccessful. He was lucky enough to get away with his prize, which he sold to a jeweller at Calcutta. After passing through the hands of various purchasers, it was bought by a Greek merchant, who sold it to the Empress Catherine for four hundred and fifty thousand dollars, and an annuity of twenty thousand dollars, with a title of nobility.

One of the best known, and probably the most famous, diamonds in the world is the Kohinoor. It is interesting for the great number of historical associations connected with it. It is said to have been worn by an Indian king three thousand years before the Christian era. From this king the Kohinoor passed through the hands of successive sovereigns of Central India, until about the beginning of the fourteenth century, when it was added to the treasures of Delhi by the Patan monarch Aladdin. In 1739 the Persian monarch Nadir Shah conquered Delhi, and had an interview with its vanquished ruler. The latter put on his best garments in order to make as good an impression as possible. He wrapped a gorgeous turban around his head, and in it he fastened the Kohinoor.

The Persian conqueror, during the progress of the interview, saw this diamond, and, in the expressive language of modern days, “went for it.”

He was too polite to capture it by main force, but proposed eternal peace and friendship to Mohammed Shah, the vanquishedruler of Delhi. The latter, like Barkis, was willin’, and the two embraced.

“As a token of our friendship,” said Nadir, “let us exchange turbans.” Mohammed was cornered and obliged to comply, and Nadir walked off with the prize. But Nadir did not keep it long, as he was assassinated soon after.

After his death it passed to the hands of Ahmed Shah of Cabool, and thence through various other hands, until in 1849, when, on the annexation of the Punjaub to the East India Company’s territory, it was stipulated that the Kohinoor should be given to the Queen of England. It was sent to England, and was delivered to the queen July 3, 1850. It was exhibited at the Crystal Palace in London, but caused great disappointment by its inability to develop the proper refraction, unless surrounded by strong lights; in fact, it was much inferior to its glass model in the Tower. Its name, Mountain of Light, seemed to be a misnomer.

RECUTTING THE KOHINOOR.

An examination was made with a view to recutting it. Scientific gentlemen were called in, and skilful cutters at Amsterdam were sent for. After much consultation, it was determined to recut the stone. The proper machinery was prepared, and set up, and the Duke of Wellington was required to begin the work.

In cutting a diamond, the stone is firmly embedded in lead at the end of a stick. Only the portion which is intended to be cut is exposed at one time. The Kohinoor was properly fixed in its leaden surrounding, and placed in the hands of the duke. He held it firmly against a swiftly revolving wheel covered with diamond dust, and in a little while the first facet was finished. Then the stone was placed in the hands of the workmen who were to continue the operation; and when their labors were completed, the Kohinoor was found blazing brilliantly, and justified its title as the Mountain of Light.

The largest and most valuable diamond in the world, so far as known, is presumed to be the one so long owned by the Sultan of Matan, Borneo. It weighs three hundred and sixty-ninecarats, and is valued at five million dollars—a very good piece of property to have; but it is said to be so carefully kept, that no ordinary diamond thief can obtain it.

ARTIFICIAL DIAMONDS.

Though diamonds cannot be made artificially, they can be imitated, and the imitation is almost perfect. Several French manufacturers of bogus diamonds have obtained high reputation for their skill. Flint, white sand, and silver are the substances used; at least they are said to be the substances, though there is doubtless some other material added which the manufacturers do not mention. These fraudulent diamonds, in weight, color, and brilliancy, are almost identical with the genuine ones, and some of them have even deceived the dealers. They will stand some, but not all, the tests applied to diamonds. They reflect the light perfectly, but are apt to grow dim in a few weeks, and require fresh polishing. The diamonds sold in New York under the name of Alaska, Australia, or California diamonds are mostly of French manufacture, and were never seen in the locality whose name is applied to them.

False diamonds have become so common among certain classes of Americans as to cause the real diamond to be used very rarely among other classes. During the prosperity of the famous Tammany Ring, false diamonds blazed on many a political shirt-front, where they could be seen and admired of men.

The followers of the Ring politicians were generally equipped with false diamonds; but the great leaders, like Tweed and his companions, decorated, or were supposed to decorate, themselves with the genuine article.

There are many strange stories told in connection with diamonds. We have already seen through what vicissitudes the famous diamonds have passed.

A story is told of a French prince, who, while travelling, was attacked by robbers. He had intrusted a valuable diamond to a faithful servant. The servant was slain, but the master escaped. He returned subsequently to the scene of the fight, and sought for the diamond, but could nowhere find it. At last he bethought himself to examine the body of hisattendant, when he found that the latter had swallowed the diamond to preserve it.

A FORTUNATE ACTOR.

Some years ago an actor, looking through an old clothes shop in London, found a pair of slippers decorated with glass beads, and suited to a character he was about to play. He bought them for a trifle, paying two or three shillings for them. He wore them on the evening of his performance, and used to leave them lying carelessly about the theatre. He had them a year or more before discovering, as he did, by accident, that the supposed beads were diamonds, and that the shoes which had cost him a few shillings were worth thousands of pounds. He sold them soon after making the discovery, and retired upon the fortune so easily obtained. He never took the trouble to ascertain their previous character or history.

About twenty years ago, in a gaming-house in New York, a gambler, who may be called Smith, put up a ring as a stake, against an outside player for a hundred dollars. The player—I call him Jones for sake of convenience,—won the ring and went away with it. Smith had received the ring a short time before as a present, and was told at the time that it was false, or, as it is generally called, “paste.” Jones took the ring next day to a jeweller, and asked what it was.

The jeweller said, “It is paste—worth about two dollars.”

“Have you a genuine stone like it?” Jones asked of the jeweller.

“Yes,” was the reply, “I have one exactly resembling it, worth five hundred dollars.”

“Will you take out the paste and set the genuine stone in its place,” asked Jones, “provided I leave you its value as security, and pay you for the use of it?”

“Certainly,” was the reply; and the bargain was quickly settled. The change was made, and Jones walked away with the ring.

HOW A GAMBLER WAS CAUGHT.

That evening he was in the same gaming-house, and was chaffed by the friends of Smith on obtaining a paste ring against a stake of a hundred dollars. Jones insisted that thering was genuine, and offered to back his opinion with a bet of a hundred dollars. The bet was taken, and it was agreed that Jones, Smith, and a person selected by the two, should go together to the prominent jewellers and ascertain the value of the ring.

Next day they visited the stores, and jeweller after jeweller examined the stone, and pronounced it genuine, and worth four or five hundred dollars. Most of them were ready to give four hundred dollars for it.

The bet was paid, and Jones departed to drive with a friend up town; but on his way he called at the jeweller’s, exchanged the genuine stone for the paste, obtained his five hundred dollars he had left on deposit, paid for the use of the diamond, and slipped away.

That evening he was again at the gambling-house, and rallied Smith on having sold himself. Smith acknowledged that he had been deceived, but he never supposed the ring was worth anything, and was surprised to find that the stone was genuine.

“Well,” said Jones, “I don’t wish to take any mean advantage of your stakes; you staked that ring for a hundred dollars, and the jewellers said it is worth four or five hundred dollars. For a hundred dollars, the amount of your stake, you can have it back again.”

Smith bit at the offer, paid the hundred dollars, and received the ring. Jones departed, and did not return. Imagine the disgust of Smith when he subsequently found out the real state of affairs.
