The growth is anticipated to continue as extra jewellers begin to promote lab diamonds and more labs are released.
Laboratory-grown diamonds have effectively precisely the same chemical, optical and Actual physical Qualities and crystal construction as purely natural diamonds. Like normal diamonds, They can be made of tightly-bonded carbon atoms. They respond to light-weight in the same way and are just as tough as normal diamonds.

Carbon-made up of gas is pumped into a vacuum chamber and deposits on to a diamond seed, crystallizing as laboratory-grown diamond. The eventual measurement in the diamond is determined by some time permitted for development.
