One of the most important task for a gemologist like us is to identify the treatments that can be found in the gemstone. These treatments include modification of color or appearance of the gemstone.

Gemstone treatments have been around for more than 2000 years. The earliest form of treatment is the Heat Treatment which was done to improve the tone of the gemstone. From Darker to lighter. This shows that treatments are done to improve the beauty within the mineral.

Recently most treatments have been accepted by the world as they make things affordable and easily accessible. But treatments of precious gemstones have been considered extremely cheap compared to the treatments in the semi-precious gemstones like tourmaline and aquamarine.

Main types of treatments that I recommend you to continue reading are:

Heat Treatment

Irradiation Treatment

Chemical Treatment

Surface Modification

Composite Gemstone

Synthetic Overgrowth

These are some of the treatments that are done most commonly in the trade.
