In contrast to naturally occurring diamonds, superia lab grown diamonds are created in labs. Yet, the two have the same chemical makeup as well as other physical and visual features. Diamonds emerge naturally over millions of years when carbon deposits buried beneath the ground are exposed to tremendous heat and pressure. Here learn more about diamonds. Manufacturing: They are generally made using one of two processes: high pressure, high temperature (HPHT) or chemical vapour deposition (CVD). Both HPHT and CVD techniques of artificially creating diamonds begin with a seed, a chunk of another diamond. The seed, together with pure graphite carbon,...
