Hydrothermal Emerald

The material for this Emerald is velvety and rich, mimicking the perfect natural Emerald, though this is without structurally compromising inclusions. It has a lovely dark appearance with extraordinary bright flashes of pure green.


Hydrothermal gem crystals are real crystals grown under conditions resembling those found in nature. A natural gem crystal forms under intense heat and pressure deep within the earth, but in a lab this process is condensed into approximately 10 months.


The Hydrothermal growth process imitates the natural formation of gemstones. The raw gemstone materials are dissolved in a water solution by being subjected to intense heat and pressure, mimicking the conditions found deep in the earth. The gem crystals grow at a very slow rate which can take up to 10 months to complete. Due to this slow and complicated process, Hydrothermal gems command a higher price than their more affordable Flame-Fusion produced cousins.
