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.
