Gemological Research Institute of Switzerland

Gemological Research Institute of Switzerland (GIS) was established in Switzerland in the 1980s as a subsidiary of the Swiss Federal Institute for Materials Testing and Research (EMPA; Eidgenössische Materialprüfungs- und Forschungsanstalt). By analyzing the chemical composition, physical properties, and natural origins of natural gemstones, combined with the most advanced gemstone cultivation technologies, GIS has achieved remarkable accomplishments in the fields of gemology and materials science.
