Dr. Edward Gübelin’s lifelong study of gems and their inclusions revolutionized the science of gemology.  From his home in Lucerne, Switzerland, Gübelin traveled to gem localities on five continents to collect samples, which he documented meticulously. After his death in March 2005, GIA acquired the comprehensive collection. It consists of more than 2,000 gems, and also includes his extensive collection of slide literature reference files and early gemological instruments. The Gübelin Gem Collection is now part of the GIA Museum, where it is being used for research, education and display.

The Collection also serves as the foundation for the GIA Gem Database Project which aims to provide a publicly accessible, searchable database containing historical and technical information on each gem in the collection, including images, gemological data, and chemical, spectrometric and X-ray data.
