A synthetically grown diamond is a peace of diamond dust that has been put under extreme pressures and temperatures, with a peace of ceramic, under a period of days, as supposed to a natural diamond, that has been cultured during a geological process.
There are several methods of producing synthetic diamonds, the original method (that is mentioned above) is “high pressure, high temperature” (HPHT) and it’s the most widely used method due to cost. The process involves huge presses that can weigh hundreds of tons and produce a massive pressure and very much heat.
