EPI

EPI-Lab

The german Institute for Gem Testing is an independent laboratory for testing of the authenticity and quality control of gemstones and minerals.

FacetEPI-Labored and otherwise cut and polished stones are analyzed using exclusively non-destructive, gemmological methods. In addition to these standard gemmological examinations, we also use the most modern, non-destructive spectroscopic methods if required. With UV-VIS spectroscopy, X-ray fluorescence analysis (RFA) and laser spectroscopy (Raman) we are able to identify synthetic stones and imitations, as well as all kinds of enhancements on real stones such as staining, fissure fillings or plastic impregnation. Rocks (mineral mix) can also be examined non-destructively.

In addition, for an exact determination of all minerals of a rock (e.g. for the correct mineralogical naming), it is possible to make a mineralogical thin section or to carry out an EDX analysis.

About Us

Gem testing require a high level of knowledge and experience. That is why we want you to know in whom you trust.

Management: Bernhard Bruder (Master of Science, European Gemmologist EG).

Bernhard BruderBernhard Bruder has stadied geology and mineralogy in Freiburg i. Br. and gemmology at the German Gemmological Society (DGemG) in Idar-Oberstein. In his subsequent job as a gem inspector in the renowned Swiss gemological laboratory SSEF, he was able to acquire a sound professional practice. Since 1998 he has been director of the Institute for Gem Testing (EPI). He is also author and co-author of several books and publications in practical gemmology.

Aside the determination and checking of authenticity of classic gemstones, he is also dedicated to the artificial changes of minerals and rocks. In this field of gemology there is an enormous need to catch up on information and education. That is why he travels throughout Germany and neighboring countries as practising gemmologist and renowned speaker.
