Gems & Gemology


This app is only available on the App Store for iOS devices.


Gems & Gemology is the award-winning quarterly journal of the Gemological Institute of America. Since 1934, G&G has published groundbreaking research on diamonds and colored stones—their sources, special characteristics, synthetics and imitations, treatments, and identification techniques.

Packed with beautiful full-color illustrations, each issue of G&G delivers:
• Feature articles: Peer-reviewed research by the world’s leading gemologists
• Lab Notes: The latest discoveries from GIA’s laboratory
• Gem News International: Global coverage of new discoveries, unusual gem materials, and current events
• Book Reviews and Gemological Abstracts: Presents current gem and jewelry books, plus articles published elsewhere in the gemological literature

With this enhanced digital version, G&G also brings you interviews with industry experts, videos spanning the world of gems, in-depth slideshows, and other new features.

Gems & Gemology is the journal that shares your passion for gems.

Please allow ample time for our media-rich issues to download.
