Suddenly diamonds are being found one after the other in the mine. Now the diamond that has been found is the biggest. A huge diamond of 1174 carats has recently been found from the Karowe mine in Botswana, which is one of the largest natural diamonds ever found. The remarkable thing is that this huge diamond was found next to some other diamonds which were of 471, 218 and 159 carats. This indicates that when originally this diamond was made, it may have been more than 2000 carats.
How are you getting big diamonds all of a sudden?
The diamond, weighing more than 1000 carats, has been found weeks after another diamond was found at the Jwaneng mine in Botswana. After this the question arises that how suddenly big diamonds are being found? Are diamonds really as ‘rare’ as it is said about them? Jody Bradby of the Australian National University says that global diamond production in 2020 was slightly more than 111 million carats, or about 20 tons of diamonds. However, only a small part of this production consists of high quality diamonds. A large number of diamonds are small and are less than one carat.
Australia’s Argyll mine is famous for pink diamonds
Australia’s Argyll mine (once the world’s largest diamond mine by volume) famous for its pink diamonds, was shut down last year because it was becoming too financially expensive to operate. This is because most of the diamonds that came out were small and therefore could only be used for industrial use. Large gem-quality diamonds, on the other hand, are extremely rare. To understand why this is so, we need to know how diamonds are formed and how they are extracted from mines.
How are natural diamonds made?
Natural diamonds are billions of years old. They form deep beneath the ground where temperatures and pressures are high enough to break down carbon atoms into dense, crystalline structures. Some scientists suggest that there are vast amounts of diamonds hundreds of kilometers deep. But till now the deepest excavation has been done up to 12 km. We will never be able to extract these diamonds located deep in the ground. So we have to work with the smaller pieces that come to the surface. Diamonds near the surface of the ground are generally believed to have come from deep-source volcanic eruptions.
Despite the many difficulties we have to face in our journey from the depths of the ground to the upper surface, the large natural diamonds that survive are often ruined during our efforts to find them. In most diamond mines, rocks are broken through explosions and then fragmented in search of diamonds. New technology, however, is facilitating the mining process of rocks using the X-ray process. This is mainly due to the ‘seizure of big diamonds’. There is a possibility that more such big gems will be found in the future. Large size diamonds are also being prepared in laboratories.
