It has long been known that diamonds occur in Australia, but hitherto the Australian stones have been all of small size, and it is notable that these are much more difficult to cut, being harder than other diamonds. Although Victoria and South Australia have occasionally yielded diamonds, it is New South Wales that has been the principal producer. The chief diamond localities have been near Mudgee, on the Cudjegong River, and near Bingera, on the river Horton.
Borneo also yields diamonds. The stone known as the 'Matan' is said to have been found in 1787 in the Landak mines, near the west coast of Borneo. It is described as being an egg-shaped stone, indented on one side, and weighing, in its uncut state, 367 carats. Great doubt, however, exists as to the genuineness of this stone, and the Dutch experts who examined it a few years ago pronounced it to be simply rock-crystal. Among other diamond localities may be mentioned the Ural Mountains and several of the United States. The largest diamond yet recorded from North America was found at Manchester, Chesterfield county, Virginia. It weighed 23¾ carats, and yielded, when cut, a brilliant known as the 'Ou-i-nur,' which weighed, however, only 11¾ carats.
A few special diamonds, from their exceptional size or from the circumstances of their history, deserve notice. Of all the great diamonds, the 'Koh-i-nur' is perhaps the most interesting. While tradition carries it back to legendary times, it is known from history that the Sultan Ala-ed-din in 1304 acquired this gem on the defeat of the Rajah of Malwa, whose family had possessed it for many generations. In 1526 it passed by conquest to Humaiun, the son of Sultan Baber. When Aurungzebe subsequently possessed this stone, he used it as one of the eyes of the peacock adorning his famous peacock throne. On the conquest of Mohammed Shah by Nadir Shah in 1739, the great diamond was not found among the Delhi treasures, but learning that Mohammed carried it concealed in his turban, Nadir, on the grand ceremony of reinstating the Mogul emperor on the throne at the conclusion of peace, offered to exchange turbans, in token of reconciliation, and by this ruse obtained possession of the gem. It was when Nadir first saw the diamond on unfolding the turban, that he exclaimed 'Koh-i-nur,' or 'Mountain of Light,' the name by which the gem has ever since been known. At Nadir's death it passed to his unfortunate son, Shah Rokh, by whom it was ultimately given to Ahmed Shah, the founder of the Durani Afghan empire. By Ahmed it was bequeathed to his son, Taimur Shah; and from his descendants it passed, after a series of romantic incidents, to Runjit-Singh. On the death of Runjit, in 1839, the diamond was preserved in the treasury of Lahore, and on the annexation of the Punjab by the British in 1849, when the property of the state was confiscated to the East India Company, it was stipulated that the Koh-i-nur should be presented to the Queen of England. It was consequently taken in charge by Lord Dalhousie, who sent it to England in 1850. After the Great Exhibition of 1851, where it had been exhibited, it was injudiciously re-cut in London by Voorsanger, a skilful workman from Messrs Coster's factory at Amsterdam. The re-cutting occupied 38 days of 12 hours each, and the weight of the stone was reduced from 1861⁄16 to 1061⁄16 carats. The form is that of a shallow brilliant, too thin to display much fire. According to Lady Burton, it is believed to bring ill-luck to its possessor.
The 'Nizam' is the name of a stone said to have been found in the once famous diamond-mines of Golconda. Sir William Hunter, however, gives us to understand that there were really no diamond-mines at Golconda, and that the place won its name by cutting the stones found on the eastern borders of the Nizam's territory, and on a ridge of sandstone running down to the rivers Kistna and Godavery, in the Madras Presidency. However that may have been, both regions are now unproductive of valuable stones. The 'Nizam' diamond is said to weigh 340 carats, and to be worth £200,000; but we are unable to verify the figures.
The 'Great Table' is another Indian diamond, the present whereabouts of which is not known. It is said to weigh 242½ carats, and that 500,000 rupees (or at par, £50,000) was once refused for it. The 'Great Table' is sometimes known as 'Tavernier's' diamond. It was the first blue diamond ever seen in Europe, and was brought, in 1642, from India by Tavernier. It was sold to Louis XIV. in 1668, and was described then as of a beautiful violet colour; but it was flat and badly cut. At what date it was re-cut we know not, but, as possessed by Louis Le Grand, it weighed only 67½ carats. It was seized during the Revolution, and was placed in the Garde Meuble; but it disappeared, and has not been traced since. Some fifty years later, Mr Henry Hope purchased a blue diamond weighing some 44½ carats (now known as the 'Hope' diamond), which it was conjectured may have been part of the 'Great Table.' It is preserved in the Green Vaults, Dresden, and is regarded as one of the most superb coloured diamonds known.
Another famous Indian diamond is the 'Great Mogul,' which appears to have been found about 1650, in the Kollur mine, on the Kistna. It was seen by the French jeweller Tavernier at the court of Aurungzebe in 1665, and is described as a round white rose-cut stone of 280 carats. Its subsequent history is unknown, and it is probable that at the sacking of Delhi by Nadir Shah in 1739 it was stolen and broken up. Some authorities have sought to identify the Great Mogul with the Koh-i-nur, and others with the Orloff.

The 'Orloff' is an Indian stone which was purchased at Amsterdam in 1776 by Prince Orloff for Catharine II. of Russia. The stone at one time formed the eye of an idol in a temple in the island of Seringham, in Mysore, whence it is said to have been stolen by a French soldier, who sold it to an English trader for £2000. The Englishman brought it home, and sold it for £12,000 to a Jew, who passed it on at a profit to an Armenian merchant. From the Armenian it was acquired, either by Catharine of Russia, or, for her, by one of her admirers, for £90,000 and a pension. It is now valued at £100,000. It weighs 193 carats, is about the size of a pigeon's egg, and is mounted in the imperial sceptre of the Czar.
Other famous stones are: The 'Austrian Yellow,' belonging to the crown of Austria, weighing 76½ carats, and valued at £50,000; the 'Cumberland,' belonging to the crown of Hanover, weighing 32 carats, and worth at least £10,000; the 'English Dresden,' belonging to the Gaikwár of Baroda, weighing 76½ carats, and valued at £40,000; the 'Nassak'—which the Marquis of Westminster wore on the hilt of his sword at the birthday ceremonial immediately after the Queen's accession—which weighs 78½ carats, and is valued at £30,000.
