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 242-1/2 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 67-1/2 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 44-1/2 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.
