Remember: We associate diamonds with jewelry, diamonds also have commercial use-cases e.g. cutting

Rewind to 1954 - General Electric (GE) create the 1st ever synthetic diamond as part of “Project Superpressure” - these were too ugly, hence could only be used for industrial use

GE had a clear motive - reduce dependency on natural diamonds 

R&D continued, by the 1970s - GE had now started to create synthetic diamonds which were gem grade i.e. could be set in jewelry BUT it was still too expensive.

GE created a process HPHT (High Pressure High Temp) - but by early 2010s, CVD (Chemical Vapour Deposition) was superior for creating jewelry focused LGDs.

And, in 2010, Pure Grown Diamonds (then called Gemesis) launched the jewelry sets with LGD

A LOT has happened since then:
