Synthetic diamonds in Japan (3'50")

Diamonds captivate people, but their mining involves environmental destruction and raises labor problems. That is why“synthetic diamonds” are now attracting attention. Japan became the first country in the world to successfully synthesize large, high-purity synthetic diamonds using the Chemical Vapor Deposition, or CVD, method. This technology has been further developed to produce diamonds for jewelry at one-hundredth the price of natural diamonds. In addition, synthetic diamond semiconductors resistant to high temperatures and radiation have been developed for use in the decommissioning of the Fukushima Daiichi Nuclear Power Plant.
