For decades, GIA has been on the cutting edge of gemological research, analyzing data on gems and their characteristics. This effort becomes more challenging each year, as new gem sources emerge and new treatment processes and synthetic materials come onto the market.
GIA Gem Project
Dr. Edward J. Gubelin Gem Collection
GIA has studied more than 400 important gemstones in the Edward J. Gubelin Collection and is committed to sharing this repository of gemological information.
