Blanks of laboratory diamonds

If we pick up two diamonds of the same size, one natural and the other obtained in the laboratory, what we will see when comparing them. Both are crystal clear and in direct light emit a kaleidoscope of spectral colors and are identical in dispersion (the ability to receive and return light). They seem to be identical. However, one of them is a billion or more years old, and the second, was recently grown in a laboratory in a month. Both of these stones are, of course, diamonds.
Modern methods of growing diamonds are carried out in just three ways. But for the industrial production of synthetic minerals, due to economic feasibility, only two of them are applicable:
Thermobaric method. (HPHT)
Electric arc method. (CVD)
The first technology is a high-temperature, under enormous dynamic pressure, the process of synthesis of minerals from carbon raw materials, in the presence of special metal catalysts. This method allows you to grow an artificial diamond for seven days.
Electric arc technology is considered more modern and the cultivation of diamonds takes only a few days. The need for gaseous carbon feedstock and maintaining an electric arc for this technology makes it more energy intensive compared to the first method. But the speed of production more than pays for all costs.

We supply diamond blanks grown in both ways. At the request of the customer, we can give our diamonds fancy shades at the production stage.
