How to distinguish between natural diamonds and synthetic di

Natural diamonds are at 200 km depth below the surface in extreme high temperature (about 1500. C) and high (about 50 000 atm) under the conditions of growth. But people already in the lab environment to create the same conditions to produce synthetic diamonds.
Over the years, synthetic diamonds are mainly used for industrial purposes, while the production of large gem quality diamonds is very complex. Gem diamonds are very expensive so that cost was bleak. But this decade with the Soviet Union, because Russia compact low-cost "BARS" technology, although the number is not in the market but have repeatedly found this type of equipment to synthetic diamonds.
Identification of natural diamonds and synthetic diamonds is imperative. But this is much more difficult than the difference between the fake diamond. Ministry of natural diamonds and synthetic diamonds from carbon atoms, and is arranged in the same crystal lattice, they have the same physical properties. The only feature of the microstructure and atomic-scale irregularities in the crystal lattice, that is, crystal defects. In this regard, due to different growth conditions, such as chemical environment, growth rate, natural diamonds and synthetic diamonds are inconsistent, today the majority of synthetic diamonds on the market was very strong yellow, orange, or brown, so it is easy to distinguish . diamond diamond.yifei8.net
However Jianding colorless synthetic diamonds is much greater difficulty, often require very complex technology health. This colorless synthetic diamond production is also very easy, which is why the market is still very rare colorless synthetic diamonds reasons. There is also a microelectronics production from synthetic diamonds the way that the chemical vapor deposition method, but still not able to produce gem-quality diamonds. (Please refer to the changed color depth and synthetic diamond)
Diamond
Colored diamond is a gem. Family-owned diamond red diamond, pink diamond, yellow diamond, blue diamond, green diamond, champagne diamond and other members of different colors, brilliant. Produce a blue or gray diamond with boron is due to the green is because the diamond to withstand long-term natural radiation, pink and brown diamonds, mostly due to growth because of the external environment when the change in crystal plastic deformation, or even a crystal structure of a defect, people have lamented the magic of nature. Which is the color saturation of red and blue diamond drilling is very rare, high quality by the world, but the number of tablets, single-carat price of up to hundreds of thousands or even millions of dollars, almost the top of the emerald (Emerald), pigeon blood ruby considerable. diamond diamond.yifei8.net
The legend on the majority of colored diamonds is a tragedy, such as our familiar blue Hope Diamond (Hope Diamond), almost every one of its owners and close relatives are killed, really creepy. Ups and downs of these tablets now gem hidden in the Smithsonian Institute in Washington, as well as diamond Blue Diamond is the most famous one of the.
The main diamond origin are: India (blue diamond), Brazil, central and southern Africa, Australia, Argyll region (red, pink diamond), most of the traditional mining.
