Description
GIA’s field gemology and colored stone research team travels all over the world to visit mines, document deposits, and collect samples of rough material—all to strengthen GIA’s reference collection.
These on-site investigations allow scientists to understand the geological environments where gems form, while also collecting stones directly from these sources to document their gemological properties, creating a foundation of data. Every specimen they bring back becomes part of a growing global archive that helps GIA identify gem origins with accuracy and consistency.
