The Gemological Institute of America recently launched the Gem Project. Comprised of data collected from gemstones in the Edward J. Gübelin collection, which the Institute acquired in 2005, the online resource includes a photo, description and gemological properties for each sample.
The GIA Gem Project is free to the trade and public at any time from anywhere in the world. The gemological information on these gemstones is also available in PDF format.
To access the GIA Gem Project, visit www.gia.edu/GIA-Gem-Project. To browse the stones from the collection, use the left-hand navigation bar under "GIA Gem Project."
