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.
When the technology for lab grown diamond first came out, the cost was not as high as that of natural diamonds, but it was not affordable for the general public either. So jewelers had no intention of using man-made diamonds to make diamond rings.
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.
