There are two main labgrown diamond production methods: the high pressure/high temperature process (HPHT) and chemical vapor deposition (CVD). Both methods are commonly used, but CVD is becoming more popular for producing gemquality synthetic diamonds for jewelry. HPHT is used more often to create synthetic diamonds for industrial use.

The majority of labgrown diamonds are created using a process called highpressure, hightemperature (HPHT) synthesis. In this method, diamond seeds are placed in a chamber with carbonrich material and then subjected to extreme pressure and heat. Over time, the seeds grow into fullsized diamonds. HPHT synthesis is the most common method for ...
