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.
