The diamond consists of carbon (chemical symbol: C) which had been under high pressure. Carbon is the 6th element of the "Periodic table of the elements". To produce synthetical diamonds we need a pressure of 55,000 bar and a temperature of 2,000 degrees. The diamond is the only stone which has got a hardness of 10. Diamonds have got a very high refractive index and to show this characteristic better they are sharpened. After this they are called brilliants. Because of the high refractive index brilliants twinkle much more beautiful than other colorless precious stones. In diamonds light is reflected a few times until it can leave the diamond. In history there were not only gold rushes but also diamond rushes. In Kimberley in South Africa many people searched diamonds and they left a very big hole. Today the most and best diamonds are hauled in Kimberley. In Russia there are many diamonds, too. For precious stones it is important that they are clean, because we cannot melt precious stones like precious metals and clean them electrolytical.
