Polish Gemmological Society (Polskie TowarzystwoGemmologiczne - PTGem) was founded in 1988. PTGem is the national organization of Polish gemmologists. Its members are coming from ranks of scientists, hobbyists, as well as jewellery manufacturers, gem wholesalers and retailers from all over the country.

The society implements its statutory activities by way of:
1. Popularization of gemmology as scientific discipline related to precious and ornamental gemstones among Polish society.
2. Introduction of scientific methods of gemmology to diagnostic evaluation of precious and ornamental gemstones.
3. Improvements of professional and ethical qualifications among Polish gemmologists.
4. Representation of PTG members in official matters with national institutions, social organizations and
other subjects.
5. Initiate and support exchange of experiences of Polish gemmologists with outside world. 

Activities of PTGem central governing board are supported by regional PTGem organizations in Szczecin (Mr. Henryk Szymanowski), Poznań (Mr. Edward Rakowicz), Kraków (Mrs. Helena Pitera), Chorzów (Mr. Jacek Ożdżeński), and Białystok (Mr. Wieslaw Śliwowski).
