Lab grown diamond were explored as early as the 18th century, but it was not until the 20th century that the development of thermodynamics and high-temperature and 


high-pressure technology made it possible to lab grown diamond 40 small diamonds were successfully synthesized for the first time in 1953 by the Swiss Engineering 


Company (ASEA) using a pressure ball device, and in 1955 by General Electric (GE) in the USA using a pressure belt device to synthesize small particles off of 


diamonds. Since then, the synthesis of industrial-grade diamonds has been widely used and almost two-thirds of all industrial diamonds have now been replaced by 


synthetic diamonds. However, it was not until 1970 that gem-quality diamonds with large grains were synthesized by the American company General Electric. After 


nearly thirty years of effort, it is now possible to obtain crystals as large as a dozen carats, but the cost of gem-quality diamond synthesis is still too high to 


allow for mass production. only 3,500ct of synthetic diamonds could be cut and ground in 2000, representing only 0.01% of natural gem-quality diamond production 


that year.
