Lab-Created Emerald:
The DNL Emerald material is created by placing a beryl (emerald) seed in a sealed, pressurized container. The container is also filled with extremely pure water. A "nutrient" containing crushed emerald and other compounds such as vanadium and chromium (emeralds natural coloring agents) is introduced into the hydrothermal environment. An electrical charge is passed through the chamber to ionize the environment and the unit is slowly heated in an autoclave. As the heat and pressure build in the sealed environment, to about 1800 degrees Fahrenheit and 800psi, the environment reaches equilibrium and the molecular de-stasis process begins. Molecules of the nutrient are stripped away and are attracted to and reform on the larger and more solid emerald seed.
These crystals grow at a rate of approximately 0.15mm per day, so a large crystal takes many weeks to form.
