We about us

In 85 years of history the German Gemmological Association has developed from a one man laboratory into a well known institution of worldwide reputation. The main goals of the association according to the statutes are to support gemmology as science and technique and the development of gemmological training and education. Following these goals consequently has led to the international reputation that the German Gemmological Association enjoys today.

Proof for the expert recognition of the work of the German Gemmological Association are numerous co-operations with the universities of Mainz, Heidelberg, Hamburg, Würzburg, etc., the university of applied science of Rheinland-Pfalz and numerous gemmological associations and institutes worldwide.

Representatives of DGemG are members of all relevant international organizations of the gemstone industry, e.g. the International Gemmological Conference (IGC), the International Coloured Gemstone Association (ICA), the World Jewellery Confederation (CIBJO), the Gemstone Industry and Laboratory Conference (GILC) und the Federation for European Education in Gemmology (FEEG).

More than 30,000 students from more than 80 different countries have participated in the training and education programs of the DGemG until today, in German or English language. The large number underlines the international recognition of the German Gemmological Traning Centre in Idar-Oberstein.

Many of those students are Fellows of the German Gemmological Association (FGG) and thus support the popularity of the association worldwide.

The different seminar programs at the German Gemmological Training Centre in Idar-Oberstein offer perfect conditions for modern gemmological education and training that is designed to meet the specific requirements of the gem and jewellery industry.
