Synthetic diamonds, also referred to as “man-made” “lab-grown” or “created” diamonds, are diamonds manufactured in a laboratory— as opposed to natural diamonds, which form naturally within the Earth.
The acute shortage of industrial quality diamonds, mainly used in a variety of industrial applications, has been improved in part by the advent of synthetic diamonds. These have been manufactured by a range of different technological processes for over half a century. However, in recent years it has become technologically possible to produce gem-quality synthetic diamonds of commercially significant size and weight.
