Laboratory-grown diamonds

   A lab-grown diamond (sometimes called man-made or synthetic diamond) is the result of a technological process,

as opposed to the geological process that creates natural diamonds.

  Lab-grown diamonds have essentially the same chemical composition, crystal structure, optical and physical properties of diamonds found in nature.

  Most lab-grown diamonds are categorized as either high-pressure, high-temperature (HPHT) or chemical vapor

deposition (CVD) diamonds, depending on the method of their production.

  Since HPHT and CVD diamonds grown in a laboratory are virtually identical to natural diamonds, differences only become clear when they are analysed in a

gem laboratory.
