Advanced Gemology Laboratory
Gemology provides advanced gemological analysis for the identification, authentication, and quality assessment
A state-of-the-art gemology laboratory is characterized by its use of advanced, often automated analytical technologies for identification, authenticity verification, treatment detection, and origin determination of gemstones. The laboratory offers a comprehensive range of specialized services in the field of diamonds and colored gemstones as follows:
Diamond Testing Services (rough and polished diamonds)
- Diamond identification and type classification
- Authenticity determination (natural vs. synthetic diamond separation)
- Treatment detection (especially HPHT treatment)
- Cut and Color grading of polished diamonds
Colored Gemstone Testing Services
- Gemstone identification based on classical and advanced testing methods
- Authenticity determination
- Origin determination of emerald, ruby, and Baltic Amber
- Treatment detection
- Natural vs. cultured pearl identification

Data Base and Calibration Samples
In the world’s advanced gemological laboratories, having a database of colored gemstones and diamonds is extremely important, as the databases of leading gemological institutions are not available for purchase or public access. Razi Gem-Sciences Institute has been committed to creating this database since its establishment. This database includes all tests of classical and advanced gemological tests. With this valuable database, RGS utilizes it not only for gemstone analysis but also as educational samples and in research.
One of the most significant research areas at RGS is gemstone origin determination. Origin determination focuses on identifying the geological and geographical source of gemstones and constitutes a significant part of our database.
