Lab Created Diamonds Description
Lab grown diamond is to artificially simulate the formation conditions of natural diamond, so that the carbon of non-diamond structure is transformed into the carbon of diamond structure. To put it simply, the raw material of graphite powder is transformed into diamond structure through high temperature and high pressure processing.
There are two main processes used to produce lab created diamonds: high pressure and high temperature (HPHT) and chemical vapor precipitation (CVD). Since 1950, the high pressure and high temperature method was used for the first time to successfully synthesize diamonds, and now the main countries that use this technology to manufacture gem-grade synthetic diamonds are China, Russia, the United States and so on.
First of all, the cultivated diamond has the same naked eye effect as natural diamond. Secondly, the price is much cheaper than natural diamond. The production process is not as violent as natural diamond mining process, and there is no problem as daily decoration. And because they are cheap, you can change them frequently, or wear large carats for a fraction of the cost. So lab-grown diamonds might be a better option.

Characteristics Of Lab Created Diamonds
Lab-grown diamonds are chemically, optically and structurally identical to mined diamonds. What does that mean?
|The Difference Between Lab Diamond And Natural Diamond|
|Attribute||Lab Created Diamonds||Natural diamond||Distinction|
|Hardness value||90 GPA||90 GPA||No|
|Thermal conductivity||2*103 W/M/K||2*103 W/M/K||No|
|Thermal property||0.8*10-6 K||0.8*10-6 K||No|

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Lab-grown diamonds have exactly the same physical, chemical and optical properties as natural diamonds, and have a hardness of 10.
Artificial cultivation of diamonds and natural diamonds, in the rough state are basically exported to India for processing and cutting, now India's diamond processing industry is quite famous in the world. It is the same in that diamonds cut in India are exported for jewellery assembly.
