As a research chemist at General Electric, H. Tracy Hall was assigned to the company's artificial diamond project, seeking to find an affordable diamond for industrial, aerospace, and manufacturing uses. In 1954, using a press of Hall's design exerting pressure of about 1.5 million pounds per square inch at temperatures in excess of 4,800F, Hall and his team achieved success. Since he was working in a GE lab, the patent was owned by his employer, but as a symbol of its gratitude the company awarded Hall two US savings bonds.

After leaving GE, Hall entered academia at Brigham Young University, where he developed an even more powerful tetrahedral press in 1957, and a later improved design called the cubic anvil press. In 1966 he founded MegaDiamond, a diamond-manufacturing company that also sells high pressure equipment.
