Synthetic diamond. A man-made diamond, produced either by subjecting carbon-bearing material such as graphite to high temperature and pressure or by the chemical vapor deposition(CVD) method. The Swedish company Allmana Svenska Elektriska Aktiebolaget(ASEA) is believed to have achieved the first repeatable synthesis of diamond in 1953, but their results were not published at the time; General Electric Company(GE) announced a successful synthesis of diamonds in 1954, followed by De Beers in 1959. Colors range from black to dark green, light green, red, yellow, blue, and colorless(Type IIa diamonds).
