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 ...
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 .
Synthetic diamonds are diamonds manufactured in a laboratory, as opposed to diamonds mined from the Earth. The gemological and industrial uses of diamond have created a large demand for rough stones. This demand has been satisfied in large part by synthetic diamonds, which have been manufactured by various processes for more than half a century.
ALTR Created Diamonds is a division of the R.A. Riam Group, a wholesale jeweler based in New York City. [2] The principles of Riam Group were heirs to a heritage of 80 years in the mined diamond business, when they released their first lab-grown diamond. [3]
The high-pressure synthesis of diamond in 1953 in Sweden [21] [22] and in 1954 in the US, [23] made possible by the development of new apparatus and techniques, became a milestone in synthesis of artificial superhard materials. The synthesis clearly showed the potential of high-pressure applications for industrial purposes and stimulated ...
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 ...
