They use two main methods: The first is called High Pressure, High Temperature (HPHT), in which ... into a larger diamond. The other method, Chemical Vapor Deposition (CVD), is like building ...

The two main methods for creating lab-grown diamonds are high-pressure high temperature (HPHT) and chemical vapor deposition (CVD). Both processes occur in controlled laboratory environments ...
