More About Lab-Grown Emerald Rough
How is the emerald rough grown?
Artificial emeralds made in a laboratory can be made using two processes, the flux melt process or the solution process. The lab grown Emerald Rough is made using the hydrothermal growth process, which is a solution process and the more time consuming and expensive.

The lab grown Emerald Rough is made up of the natural emerald in a hexagonal crystal system. It is clean with little to no inclusions and has a hardness level of approximately 7.5 on the Mohs hardness scale, but is less brittle than a natural emerald.

FAQs on Lab Grown Emerald Stone Rough
How to measure carats in lab-grown rough emerald stones?
A loose emerald stone in the rough can be weighed as it is to get the carat size through converting from grams.
Cutting, faceting and polishing necessary for producing a finished cut emerald stone will however mean that the carat weight of a cut stone will be lighter than the carat weight of the loose emerald stone in rough from which it is made.
Are lab-grown emerald stone worth more cut or uncut?
An uncut lab-grown emerald stone in the rough is valuable in itself due to the transparent and humane supply chain from which it comes. Its light eco-footprint also adds to its value. A cut emerald stone that is lab-grown is worth more because of the added costs of skilled
labour used to expertly cut an emerald stone. It is cut and faceted in such a way to refract the best amount of light, all while maintaining as much carat size as possible to be ready for use in jewellery pieces.
How to choose the right uncut lab-grown emerald stone?
To choose a top-quality rough emerald stone that has not yet been cut, consider the colour saturation, shape and clarity. A unique colour or colour-play ability, such as found in opals, will show that the finished product will stand out after cutting and polishing. Shape and symmetry will determine whether it can be easily faceted or cabbed into the desired form that is easily mountable for its use, such as in jewellery.
A large rough emerald stone may not yield many smaller pieces if it is irregularly shaped, meaning increased waste during gem cutting.
Can I cut lab-grown emerald rough?
Yes—if you have lapidary experience and access to proper tools, you can cut your own lab-grown emerald rough. However, we recommend working with a professional lapidary for optimal brilliance, especially if the gemstone is for resale or fine jewelry.
Is lab-grown emerald rough good for engagement rings or custom fine jewelry?
Absolutely! Because it is physically identical to natural emeralds, lab-grown emerald rough is perfect for ethical, custom-designed engagement rings, birthstone jewelry, and artisan pieces—without the ethical concerns or high price tag.
