What is hydrothermal treatment ?
One of the most popular methods for creating synthetic emerald is the hydrothermal process, which uses heat and pressure to imitate natural conditions deep in the earth that formed natural gems. Nutrients are dissolved in a water solution with synthetic crystals forming as the solution cools.
