  Natural diamonds are formed under high temperature and pressure for geological reasons, and it takes tens of thousands or even tens of millions of years to form them. synthetic diamond costds are produced by scientists in a short period of time (one to three weeks) by simulating the growth environment of a natural diamond, under the same high temperature and pressure conditions, using very sophisticated instruments.
