Overview

Diamond Synthesis Review


Details

Recent technological breakthroughs have yielded exceptionally large, high-quality laboratory-grown diamonds grown by high-pressure and high-temperature (HPHT). From the frontiers of diamond growth comes this look at the latest laboratory-grown diamonds and the next generation of low-priced, mass-produced goods with physical properties never encountered before.
