"The man made diamond 'is also known as synthetic diamonds, and this" artificial diamond "or" lab created diamond is' to chemical and physical processes in the diamond mines. The main difference between "A diamond made" and the natural diamond is the composition of carbon-dimensional crystals. The 'lab created diamond' or 'artificial diamond ", produced under various names, such as diamond, diamond, artificial diamond or industrial diamonds seized are not known." E 'Diamond "is composed of both silicon carbide, and zirconium oxide.

History of Laboratory Created Diamonds

The first 'man made diamond' was produced in Sweden in 1953 by the Fifth and an engineer Anders Kampe. The lab created the diamond manufacturing process, used machines were large and bulky, which were designed by Baltzar von Platen. But this feat not many was unknown. After a year, General Electric is a big step in the production made "manDiamond '. This move has encouraged many aspiring young people and the "artificial diamond" industry was born in the nineteenth century. The most important industrial lab created diamonds or "man made diamonds", the GE Super abrasives and diamond De Beers was.

Born around 1980 and some additional "artificial diamond" industry in Korea. Later, the Chinese pioneers created diamonds processed in the laboratory. GE Super abrasives after their 'lab created soldDiamond "Little John and drive this innovation was called the Diamond Company in 2003. During this period, De Beers Industrial was established in two different" artificial diamonds was "industries and the second branch splits known as Element Six.

Currently, there are many "man-made diamond 'industries around the world and some are known as the diamond industry Sumitomo Electric Carbide, Diamond Smith, Mega and the United States of synthetic diamond industry. Today, the" schoolcreated diamond 'has a market of one billion dollars and produces about 3,000 million carats of diamonds, man made in a year. From these 3 billion carats, only 130 million carats are used in the production of precious stones.

Production process laboratory created diamonds

To create a diamond, there are basically two methods used nowadays. One method is high pressure, high temperature method and commonly known as HPHT method in '"Man of diamonds"Production arena. As the costs of production less in this process so that it is a popular method used throughout the world. The most important accessory is a press used a heavy pressure of 5 GPa and temperature, which is formed by the pressure to 1500 degrees Celsius provides. Diamond is best known as a "man of diamonds", produced by all these processes in the Earth's crust known. In this process there are two types of presses and are used by pressing a press belt and a cube.

AnotherMethod used in the 'lab created diamond "of the chemical vapor deposition is that as a method of CVD. With this method, the carbon plasma is one on top, in which carbon atoms form tiny" Man Made Diamond' are formed. Used in this gas to power various CVD conditions suitable for growth of diamond on the upper level. This method of chemical vapor deposition was introduced 1980
