Man Made Diamond: How Is A Diamond Made
‘Man made diamond’ is also known as synthetic diamond and this ‘man made diamond’ or the ‘lab created diamond’ undergoes a chemical and physical process in the diamond mines. The main difference between ‘Man made diamond’ and the natural diamond is the composition of three dimensional carbon crystals. The ‘lab created diamond’ or the ‘man made diamond’ are known by various names such as manufactured diamond, artificial diamond, industrial diamond or the cultured diamond. ‘Man made diamond’ is manufactured either from the silicon carbide or the cubic zirconium.
History of the Lab Created Diamond
The first ‘man made diamond’ was manufactured in Sweden in 1953 by Quintus and by an engineer Anders Kampe. This lab created the diamond manufacturing process, bulky and huge machines were used which were designed by Baltzar Von Platen. But this feat was not known to many people. After one year General Electric took a giant step in manufacturing the ‘man made diamond’. This step encouraged the many young aspirants and the ‘man made diamond’ industry came into existence in the nineteenth century. The main industrialist in lab created diamond or the ‘man made diamond’ was the GE Super abrasives and the De Beers Industrial Diamonds.
In and around 1980 some additional ‘man made diamond’ industries were formed in Korea. Later on the Chinese became the pioneers in the lab created diamond process. GE Super abrasives later on sold their ‘lab created diamond’ unit to Little John and this was named the Diamond Innovation Company of 2003. During this same time De Beers Industry was divided into two different ‘man made diamond’ industries and the second industry was known as Element Six.
At present, there are many ‘man made diamond’ industries available around the globe and some are well known diamond industries such as Sumitomo Electric Hard Metal, Smith Mega Diamonds and the United States Synthetic Diamond industry. Today the ‘lab created diamond’ has a market of one billion dollars and produces around three billion carats of the Man made diamonds in a year. Out of these three billion carats only 130 million carats are used in the manufacturing gems.
Manufacturing Process Of Lab created Diamonds
To create a diamond, there are basically two methods that are used now days. One of the methods is high a pressure, high temperature method and commonly known as HPHT method in the ‘man made diamond’ manufacturing arena. As the production cost is less in this process, making it a more popular method used world wide. The main accessory used is a heavy press that provides a pressure of 5 GPA and the temperature that is formed due to this pressure is around 1500 degree Celsius. The diamond better known as ‘man made diamond’ is created by all these procedures inside the earth’s crust. In this process there are two types of presses used and they are a belt press and a cubic press.
Another method used in ‘Lab created diamond’ is the Chemical Vapor Deposition which is also called the CVD method. In this method carbon plasma is formed on the top where the tiny carbon atoms are made form a ‘Man Made Diamond’. In this CVD various gases are used to energize the suitable conditions for diamond growth on the top layer. This method of Chemical Vapor deposition was introduced in 1980.
