Gemstones that have been produced by the nature are called natural gemstone. They are not man-made gemstones
Every single emerald sold from our company is a natural emerald. we do not sell man-made emeralds, or simulant (imitant) emeralds.
A synthetic material and/or a natural material that a have superficial resemblance to a gemstone which it imitates is called a simulant.
Most of the emeralds have been enhanced. The most common and accepted treatment method is oiling either with a resin or natural oils.

We will always disclose the treatment of the emerald.
