Who invented lab grown diamonds?

The first successful creation of lab-grown diamonds is credited to Dr. H. Tracy Hall, a research scientist at General Electric. In 1954, he and his team developed the High-Pressure High-Temperature (HPHT) method, which replicates the natural conditions of diamond formation. This technique led to the production of synthetic diamonds, primarily for industrial use. Advancements for producing gem-quality diamonds came later with the Chemical Vapour Deposition (CVD) process in the 1980s. While Hall laid the groundwork for synthetic diamonds, the progression to gem-quality production was a collective scientific effort.
