His journey began as a technical assistant at the Mineralogical Institute of the University of Basel, where his fascination with minerals led him to pursue advanced studies, culminating in a PhD on beryl from the Swiss Alps in 1980.<\/span><\/p><p class=\"cs2654AE3A\"><span class=\"csF4BEBF9A\">In 1990, Professor H\u00e4nni assumed the role of Director at SSEF, where he made invaluable contributions to the institute&#8217;s development and international reputation. His groundbreaking research in pearl and coloured stone analysis, treatment detection, and origin determination has left an indelible mark on the field of gemmology.\u00a0<\/span><\/p><p class=\"cs2654AE3A\"><span class=\"csF4BEBF9A\">Even after his retirement in 2009, Professor H\u00e4nni remained actively engaged in gemstone research and education.
