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.
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 ...
Within the category of industrial diamonds, there is a sub-category comprising the lowest-quality, mostly opaque stones, which are known as bort. [124] Industrial use of diamonds has historically been associated with their hardness, which makes diamond the ideal material for cutting and grinding tools.
Sir Ernest Oppenheimer formed Industrial Distributors in 1946, the first entity to focus on the industrial uses of natural diamond. [1]In 1956 it was decided that De Beers should make a concerted effort to produce synthetic diamond and, in response, a research group, called the Adamant Research Laboratory, was established and housed as a subdivision of the laboratory.

Diamonds are one of the best-known and most sought-after gems, and they have been used as decorative items since ancient times. The hardness of diamond and its high dispersion of light—giving the diamond its characteristic "fire"—make it useful for industrial applications and desirable as jewelry. Diamonds are such a highly traded commodity ...
Hall produced synthetic diamond in a press of his own design [2] on December 16, 1954, and showed that he and others could repeat the process following Hall's procedure, a success which led to the creation of a major supermaterials industry. Hall was one of a group of about a half dozen researchers who had focused on achieving the synthesis for ...
Industrial diamonds are valued mostly for their hardness and thermal conductivity, making many of the gemological characteristics of diamonds, such as the 4 Cs, irrelevant for most applications. 80% of mined diamonds (equal to about 135,000,000 carats (27,000 kg) annually), are unsuitable for use as gemstones, and used industrially.
