The atomic hydrogen formed helps the free carbon to form diamonds. It works by using high pressure and temperature to break down methane into carbon and hydrogen. Chemical Vapour Deposition (CVD): One of the processes to create lab-grown diamonds. Lab created or lab grown sapphires, rubies and emeralds are identical to their mined counterparts, but at a fraction of the.Flux Growth: Gemstone nutrients are dissolved in another material known as flux which can dissolve the elements at a lower temperature, and then be forced to precipitate into crystalline form.As the solution cools, the gemstone crystal forms. ![]() It involves dissolving the needed nutrients in water using very high pressure.
