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 ...
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.
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 .
The past can be quite fascinating.Those of us living in the present find it really interesting what life was like 50, 100, or even a 1,000 years ago. Luckily, we can go almost 200 years to the ...
The first lab-grown diamond was produced in the 1950s, and now, Dubai-based company 2DOT4 hopes to transform the city from a gem trader to a diamond producer. A tech company is growing diamonds in ...
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."
