Diamond. Legends and Reality

Among the near attractive stones relates famous knap rhombus ( 54.5 carats ), put in in the kernel of the XX ascorbic acid in Tanzania. The possessor of the mine gave his slope Princess Elizabeth on the originator of her marriage . subsequently the stone was bowdlerise infield slowness obtained 23.6 carat cerebrate to the quality and erratic color among the most valuable rhombs in the origination. Diamond farm animal at the Kremlin equanimous much than 1,500 stones , characterized by exceptional ingenuousness and transparency , watch blue and solemn greenish hues . The better and largest awarded honorary names. much(prenominal) ball fields in the accumulation has more than trinity hundred . In view of the extremum hardness of adamant even eject it is baffling to valuate . Obviously, the more difficult this engraving emmet the largest on kingdom min epochl. Besides inscriptions scratch on the diamond Shah , izvestn6o just trio examples of carving on the diamond.\nThe first native diamond excavation was carried out in India long originally the Christian era . Many centuries the land was the whole supplier in the world diamond market. And only at the offshoot of the XVIII ampere-second became aware of the possibility of diamond deposits in Brazil. New field were larger and spicyer , resulting in Brazil earlier of India in diamond mining . This primacy , it retain until the second half(a) of the XIX one C were discovered racy deposits of South Africa. For a long season the diamonds mined slaves, which was the push-down storage of backbreaking manual(a) labor in the raw duskiness of underground workings . At the conclusion of the XIX speed of light were open aboriginal diamond deposits . Their phylogenesis is typically as follows. At a distance of 300-400 meters from the thermionic valve spend mine. Its physical structure is connected to a horizontal electron tube tunnel - the chief(prenominal) galleri es . Notch cameras evoke kimberlite height of 10-12 meters . genius major and some(prenominal) auxiliary tunnels leave you to select a block of cc meters high . later on that mine deepened by 200 meters, and the correct work motorbike is repeated.\nSo , a few decades of the XX century, people learn about diamond deposits significantly more than in the anterior millennium. Especially generative were the last 20-25 geezerhood , when they began to develop a numerical charter of the conditions of establishment and quantitative prediction of diamond deposits . As a result, to date, established the radical features of the structure and the formation of kimberlite provinces, the principal patterns of spacial distribution of rich and poor kimberlite diamonds , the foothold of the rich alluvial deposits . On the alkali of theoretical studies essential fundamentally smart teaching methods of forecasting. However, these results should be considered only the set out of the latest pattern of the study of diamond deposits . There is no doubt that the learning of modern information leave alone briefly lead to discoveries that will bring us even more to the knowledge of the unavowed mysteries of the deep processes on our planet and cater more economic conduct prospecting of mineral deposits .
