Synthetic diamonds

In 2016, there were 213 million carats of synthetic diamonds that were imported into the United States. Exports out of the United States have increased since 2007 from 102 million carats to 129 million carats in 2016. Production in the country has mostly remained at a similar volume in the past ten years. In 2007, the U.S. produced 130 million carats of synthetic diamonds through primary production and 17.6 million carats of synthetic diamonds through secondary production. In 2016, primary production had decreased to 125 million carats and 33.4 million carats from secondary production.

Synthetic diamonds are artificially produced, often in laboratories. Two of the most common production methods are through high-pressures and high-temperatures as well as through the formation of crystals through chemical vapor deposition, generating the names HPHT diamond and CVD diamond, respectively. Worldwide, some 4.41 billion carats of synthetic diamonds were produced in 2016, a slight decrease from the 4.42 billion carats in 2007. Synthetic diamonds are often used as abrasives, as part of cutting and polishing tools. New applications for these materials have also been developed, for examples, as high-power switches at power stations and as light-emitting diodes. It can also be used as detectors for ultraviolet light and high-energy particles, essential in certain research facilities.
