The first synthetic diamond

The first synthetic diamond was produced in 1954 in the laboratories of General Electric (GE) in the United States. This groundbreaking research led to the first large scale, industrially viable process for making synthetic diamonds.

The synthetic diamond that GE produced was created using the High Pressure High Temperature (HPHT) method. This process simulated the natural conditions under which diamonds form in the Earth’s crust and allowed the creation of large, pure synthetic diamonds. This first synthetic diamond ushered in an era of laboratory diamond production that has since grown into a broader industry. These days, synthetic diamonds are used in many areas including jewelry making, industry, science, and technology.
