2. Identifying Gemstone Treatments Seminar
Saturday, Feb. 6, 9 to 11 a.m.
This presentation and hands-on lab led by GIA instructors will introduce participants to the various treatment processes used in the gemstone market, as well as treatment identification of commercially important gemstones used in jewelry.

GIA’s museum exhibit “Striking Gold!” will be held at
GemFair from Feb. 2 to 7. A number of transparent yellow gem species and varieties on the market, including sapphire, citrine, topaz and more unusual, collector gem minerals, will be on view.
At the Tucson Gem and Mineral Show, the museum will have an exhibition called “Mother Nature Sings the Blues,” featuring blue gems and jewelry to coincide with the show’s “Shades of Blue: Minerals of the World” theme.
Library Exhibit
The GIA’s library will feature some of its mineralogy and gemology books at the Tucson Gem and Mineral Show. “Providing Access in a Digital World” will give visitors insight into the library’s recent digitization project, which made many of its rare and historically significant books available online to the public.
