The breed, variety, origin and quality level of the stone can be determined by a specialist such as a gemologist. How often have you come across this word and have you ever thought about the need to check the stones in the jewelry you purchase?

The profession was fully formed in the 20th century, when precise methods for studying mineral matter appeared.

In 1908, the world's first specialized institution appeared in Great Britain - the Gemological Committee, formed by Great Britain's National Association of Goldsmiths. It was then transformed into the Gemological Association.
