Welcome to Gemological Institute of Europe

Gemological Institute of Europe was established to protect consumers when buying or valuing their diamonds, precious stones and precious jewellery. GIE is an independent foundation with offices around Europe and the world. GIE has been serving the international diamond industry for more then 30 years.

GIE operates various services dependent on the individual laboratory. However all our laboratories offer our core services: Diamond Lab, our full service diamond grading laboratory, which is respected world wide by the diamond industry and by the general public alike; Precious Stones Lab; Jewellery Valuation Service.

In addition we invest heavily in Research and Development to counter the growing use of Laboratory Enhanced Diamonds. GIE stands for quality, tradition and the highest standards. We regularly meet with our laboratory directors to inform and update on current equipment and enhancements and to stabilize the gradings and services offered from our laboratories. GIE is contactable primarily via email webinfo@gielab.com.
