I guess that's what they're saying. Contrast with: From https://en.wikipedia.org/wiki/Synthetic_diamond https://en.wikipedia.org/wiki/Synthetic_diamond Synthetic diamond is also widely known as HPHT diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively) And from https://en.wikipedia.org/wiki/Synthetic_diamond#Chemical_vapor_deposition https://en.wikipedia.org/wiki/Synthetic_diamond#Chemical_vap... Unlike HPHT, CVD process does not require high pressures, as the growth typically occurs at pressures under 27 kPa. [...] and optimizing the substrate temperature (about 800 °C)
