What are the differences between synthetic gems?

Synthetic gems are also called lab-grown gems. However, if you are confused between synthetic gems, this guide is just right for you. Here we have provided all the details about both of these gems. About Natural Gems As the name indicates, natural gems are those that have formed in nature without human intervention. These gems have a very slow development process, requiring certain conditions (for example, to obtain rubies, the rocks where they are formed must be poor in silica and rich in aluminum). These gems are mined from the earth, either in primary or secondary deposits. But in both cases, it is a very expensive job, which is why they are much more expensive than synthetic ones. Natural gems are often treated to improve their color or reduce their inclusions. These products, depending on the type of treatment they have, will be considered natural gems, treated (whether by heat treatment, resins, laser, etc.), manufactured material, or artificial. Some treatments are widely accepted by the trade and gemological professionals, such as oiling emeralds.  This treatment does not affect the chemical components of the stone, nor does it alter its color. Other treatments that are accepted are heat treatments on corundum, to improve its color. However, certain treatments are highly persecuted and, if they are not communicated when selling them, it is a scam (this is the case of rubies with lead glass, for example). About Synthetic Gems As we have mentioned above, synthetic gems are also known as “Lab created gems”. These are stones that are manufactured by imitating the chemical composition and crystalline structure of natural ones. They are identical to their natural counterparts, in appearance, structure, and physical properties (such as hardness). The difference between natural and synthetic gems is that the latter are manufactured with human help in controlled environments and have lower prices due to their wide availability. Currently, there are different methods for creating synthetic stones, such as the Melt method, the Flux method, or the Hydrothermal method. Some of them are relatively inexpensive, with an hours-long production process. However, in other cases, these are very expensive methods where the material has to remain for months at very constant pressures and temperatures. Depending on the type of process, the inclusions that the stones present can be almost identical to natural ones since they tries to reconstruct the conditions of nature as much as possible.
