Apply in 57 cutting edges have started in the XVII century, but only at the beginning of the XX century with the help of theoretical calculations that take into account all the physical and optical characteristics of diamond, were derived ideal proportions cut, allowing to achieve maximum brightness and maximum play of light within the stone. This became known facet of the present or perfect, it at the top of the diamond has 33 and 24 on the lower face.

1st PLACE. Antimatter. Cost: 62.5 trillion dollars per gram. Antimatter is known as the most expensive substance on Earth, according to NASA in 2006, the production of milligrams of positrons was worth about 25 million U.S. dollars. According to the 1999, one gram of antihydrogen would be worth 62.5 trillion. According to CERN in 2001, the production of a billionth of a gram of antimatter (the amount used in the CERN collisions of particles and antiparticles in ten years) was worth several hundred million Swiss francs. Antimatter in the future, it is theoretically possible to use as a fuel for the spacecraft to other planets. The problem is that its production is incredibly expensive technologies are required, and to create just 1 gram, the world would have to work a whole year (global GDP is 65 trillion. Dollars).
