Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...
Herbert Maxwell Strong (September 30, 1908, Wooster, Ohio – January 30, 2002, Schenectady, New York) was an American physicist and inventor, known as part of the General Electric (GE) team of researchers who synthesized diamonds in late 1954, as announced by GE in early 1955.
Synthetic diamonds are produced via high pressure, high temperature or chemical vapor deposition (CVD) technology. These diamonds have numerous industrial and commercial uses including cutting tools, thermal conductors and consumer diamond gemstones .
1972 American Chemical Society Award for Creative Invention: "For being the first to discover a reproducible reaction system for making synthetic diamonds from graphite, and for the concept and design of a super high pressure apparatus which not only made the synthesis possible, but brought about a whole new era of high pressure research."

Gemesis Inc. was a privately held company located in New York City.The company grew synthetic diamonds using proprietary technology.. Gemesis had the world's largest facilities for both the high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD) diamond production methods.
The company described those diamonds as being so hard that they could only be cut using powder of other Arkansas diamonds. [4] The final result was a 12.42-carat (2.484 g) emerald-cut gem. It was characterized as M on the diamond color scale; this nominally corresponds to a faint yellow color, but the visual impression of Uncle Sam has been ...
The Jones Diamond, also known as the Punch Jones Diamond, The Grover Jones Diamond, or The Horseshoe Diamond, was a 34.48 carat (6.896 g) alluvial diamond found in Peterstown, West Virginia by members of the Jones family. It remains the largest alluvial diamond ever discovered in North America.
Ekati Diamond Mine, 2010. Fipke is credited as a co-discoverer of the mine, and retained a 10% interest until 2014, which made him a very wealthy man. Charles Edgar "Chuck" Fipke CM (born 1946) is a Canadian geologist and prospector who discovered the existence of diamonds around Lac de Gras in Canada's Northwest Territories. He is now a ...
