摘要

Estimated 2013 world production of natural and synthetic industrial diamond was about 4.45 billion carats.. During 2013, natural industrial diamonds were produced in at least 12 countries, and synthetic industrial diamond was produced in at least 12 countries. About 97 percent of the combined natural and synthetic global output was produced in China, Ireland, Russia, South Africa and the United States. During 2013, China was the world's leading producer of synthetic industrial diamond, followed by the United States and Russia. In 2013, the two U.S. synthetic producers, one in Pennsylvania and the other in Ohio, had an estimated output of 103 million carats, valued at about $70.6 million. This was an estimated 43.7 million carats of synthetic diamond bort, grit, and dust and powder, with a value of $14.5 million combined with an estimated 59.7 million carats of synthetic diamond stone, with a value of $56.1 million.
