Some of treatment procedures are centuries old, while others are relatively new. Gemstone are treated in different ways to improve their appearance. Some of these procedures are centuries old, while others are relatively new. Also, without cutting or polishing a gemstone could not reveal fabulous colors and amazing sparkle. If we are speaking of treated or enhanced gemstones, we mean any process that a natural gem has undergone to improve its color, clarity, durability or availability beyond cutting and polishing. Please keep in mind that TREATMENT AND ENHANCEMENT has nothing to do with synthetic, man made "gems". Treating and enhancing gemstone is a very common step to implove gems appearance. Some treatment and enhancements improve on nature, cannot be detected and are permanent; this provides the gem market with a larger supply of beautiful gemstones. That does not sound very professional. What is happening here is that the treatment and enhancement procedure so closely resembles what happens in nature, that one cannot always tell if they have been treated after mining or before. Microscopic examination will sometimes reveal an inclusion that burst during heating treatment, but lacking that there is no way to tell exact that heat treatment was done before or after mining.There are various techniques to so. In the following, the most important facts are briefly explained.

Oiling treatment method has been used for more than 600 years, mostly on fissured and porous gemstones - especially emerald. Other colored stones such as rubies and alexandrite have been treated with oils and resins to make surfacing inclusions less visible.

Heating treatment is the most common form of enhancement. This is so common with corundum, (ruby and sapphire,)

Beryllium Heating treatment probably catalyst causing thermo-chemical reaction in the corundum's atomic structure. This was made a point to produce yellow and orange sapphires.

Diffusion treatment is method in which certain elements such as iron and titanium are added during the heating of the gemstone. It is also frequently called "surface diffusion".

Irradiation treatment is pounding material with subatomic particles or radiation enhancement. Sometimes irradiation is followed by heating to produce a better or new color for the gems - such as topaz.
