Lab grown diamond technology
To achieve the best possible result for a Lab Grown Diamond, the diamond is created in an environment similar to that in which natural diamonds are formed.

A lot of research went into the creation of Lab Grown Diamond. In the formation of natural diamond, carbon particles come together under intense pressure, deep below the earth’s surface. In order to eventually find diamond, these particles need to be compressed this way for millions of years.
After the natural diamond is created, she has to be mined. Deep mines have to be dug to mine these diamonds. The way in which these mines operate has a harmful impact on the environment. This is one of the reasons that many mines are being shut down.
For many years scientists have tried to create imitations of diamond. From zirconia to synthetic diamond, they never mentioned to create an identical diamond. To find out more about the imitations of diamond, click here.
The HPHT technology currently used to manufacture Lab Created Diamond has existed for a much longer period of time. This technology had already been used in Russia to create diamond for industrial purposes. The diamonds that were produced this way lacked in quality to the extent that they were unfit for use in jewelry. Nowadays this technology may be used to produce high quantities of high-quality diamond.
How are Lab created diamonds made?
Lab grown diamond through HPHT
Just like natural diamond, Lab grown Diamond consists of carbon particles. These tiny particles are placed in the machine as if they were seeds. The size of glass splinters, these particles are carefully checked for quality and pollution in order to produce the highest possible quality diamond.
The machine will compress the particles under immense pressure and incredibly high temperatures, just like the natural process. Nature, however, does not allow us to influence the particles being compressed and facilitates the occasional impurity or inclusion. This is what makes the naturally clear diamond extremely valuable.
The process, developed by scientists, is called HPHT, or High Pressure High Temperature.
Natural diamond forms at temperatures of 1204 degrees Celsius, Lab Created Diamonds, in contrast, are formed at a temperature of around 500-600 degrees Celsius.
In the beginning, it was difficult to make colorless diamonds and they usually came out yellow-orange diamonds and other colors and the part that was colorless was very small. Nowadays they have more control over this and even top quality diamonds are now being made. The beauty of Lab created diamonds is that they also come in all sorts of colors. For example, the pink diamond in natural has become so extremely expensive that it is almost unaffordable. But in lab created it is readily available. The expectation is that because of this, the colored diamonds will also get a revival in the market.
Lab grown diamond through CVD
The process of CVD diamonds is completely different from the natural process and the HPHT process. CVD means Chemical Vapor Desposition.
In CVD diamonds, a diamond is formed by evaporating a mixture of hydrocarbon gases under pressure. Diamonds are formed on a special platform where carbon remains after evaporation. Nowadays this is one of the most used methods to form a diamond.
Difference Lab Grown and imitation diamond
Lab Grown diamonds are still regularly confused with zirconia, mossanite or synthetic diamonds, but they are definitely not the same. These are absolutely not diamonds. For more information on all diamond imitations, click here.
