In the 1990s, chemical vapor deposition (CVD) was used to synthesize diamond films, which were deposited on solid-phase substrates to form polycrystalline films of diamond for industrial use. As society developed and people's living standards rose, they slowly reached a point where they could accept artificial diamonds. As a result, jewelers began to make diamond rings with synthetic diamonds.
2003 saw the synthesis of gem-quality single crystals by Apollo in the USA, and commercial production began. More recently, the Geophysical Laboratory of the Carnegie Institution of Washington, USA achieved a CVD synthesis rate of 100μm/h to produce a 10ct, half-inch thick single-crystal diamond.
