What is Lab Grown Hydrothermal Emerald?
Emerald Process method is made by hydrothermal growth (newest “Platinum” technology) which is slow and only method for successfully growing synthetic Emerald. This process requires heat and pressure and imitates the conditions deep in the earth that result in the formation of natural gems. Nutrients are dissolved in a water solution, and then synthetic crystals form as the solution cools to produce a Emerald gemstone.
