"To tell the truth there is no fraud or deceit in the world which yields greater gain and profit than that of counterfeiting gems." Pliny [23–79 AD],

Keeping abreast of gemological developments, even for those who have chosen to make gemology their profession, is challenging. Apart from the accurate identification of all gemstone species and varieties, from the relatively common to the extraordinarily rare, and even with the ever presence of synthetic equivalents; today it is the identification of treatments being applied to gemstones that present the greatest challenges.

All of the popular gemstones and pearls have treatment identification challenges; examples include the HPHT treatment of diamond both to remove and add color; the filling of fractures (in diamond, ruby, emerald, tourmaline etc.) with glass, resins or oils to hide the fractures and improve clarity; the irradiation of various gems (topaz, diamond, tourmaline, cultured pearls, etc) to change their color; the coating of gems (topaz, diamond, pearl etc) to add color, effects or improve durability; the heating of gemstones (aquamarine, tourmaline, ruby, sapphire, spinel etc) to improve color and/or clarity; and the diffusion of foreign elements into stones (ruby and sapphire) to change color.

These and other treatment challenges emphasize the need for well equipped and professionally staffed laboratories such as GIA Research (Thailand) - GRT, for it is only through their professionalism and independence that all involved in the purchase and sale of gemstones can function with confidence. Allowing all concerned to focus without concern on the joys associated with the possession of rare and beautiful gemstones.

In conjunction with the GIA Laboratories in New York and California, GIA Research (Thailand) undertakes a considerable number of research projects throughout the year while at the same time providing the following Report and Consultancy Services to assist all those involved in the sale and purchase of gemstones and pearls.

Identification Reports - professionally document the results of a full examination of a material. The results detailed will identify the material examined giving such identifying characteristics as; color, transparency, shape, cut, dimensions weight and a color photo. The full report will also state whether it is natural or synthetic and if the material has been treated to enhance its appearance by an identifiable treatment. It will also be noted if it is a stimulant with no know natural counterpart, or if it has been assembled from two or more separate components.

Origin Reports – are available for ruby, sapphire, emerald and para?ba tourmaline. These reports give all of the detail normally included in the “Identification Reports”, plus they give a scientific and experience based professional opinion on the geographic origin of the examined stone.
 
Analytical Reports - professionally document the results of a full examination of a material as in the “Identification Report” and “Origin Report” services. In addition the Analytical Report provides the full data from which conclusions were reached. The data included would be; normal gemological data such as RI, SG, Visual Spectroscopy, fluorescence, inclusions, color distribution, plus UV/visible/NIR, IR, and Raman spectroscopy and chemistry as appropriate.
