Visit GIA’s stand on the Galleria Level to see what’s new in 2019 in Education, Laboratory Services, Instruments and the Retailer Support Programme. Check out the latest issue of Gems & Gemology, or take in a GIA instrument demo. Beyond the stand, submit your coloured stones to the GIA Show Service Laboratory, attend your choice of seminars and free presentations to advance your gemmological knowledge, and don’t miss the GIA Alumni Association’s “Party at the GIA Gem Mine – An India Odyssey”.
GIA Show Service Laboratory
GIA will offer convenient access for coloured stone identification and identification and origin lab services at the show. Drop off your stones for expert analysis and report services in the Onyx Suite with GIA’s on-site team of gemmologists.
The GIA Show Service Laboratory will be available:
4-9 Feb 9 am to 4 pm (opens one day before AGTA GemFair begins)
10 Feb 9 am to 12 pm
Come prepared and save time, especially if you are new to this service. Click here to learn more about submitting stones to the GIA Show Service Laboratory.
Note: Services will be available one day before the AGTA GemFair opens. Hours of operation differ from show hours. Temporary reports will be printed on site; permanent reports will be sent after the show. Submit your stones early for these popular services. Diamond and pearl report services will not be available.
For more information, call +1 760 603 4517.
GIA will offer three fee-based educational seminars at the Tucson Convention Center during the AGTA GemFair. To register for the seminars, please complete the form below or contact GIA Admissions on +1 760 603 4001.
Identifying Laboratory-Grown Diamond
Laboratory-grown diamonds are developed in laboratories and factories over short periods of time. A rapid increase in this technology over the past decade has added to the availability of laboratory-grown diamonds in the jewellery marketplace. Now, more than ever, full disclosure and confidence in knowing what you are buying is critical. Through interactive, guided discussion and a hands-on lab, this seminar will cover HPHT and CVD laboratory-grown diamonds and how to separate them from natural diamonds.
Friday, 8 Feb, 1 pm to 3 pm, Coconino Room
Emerald: Country of Origin Determination
This two-hour lecture and lab session will utilise specimens from GIA’s country of origin sample collection. Sourced directly through our field research efforts, this collection will be used to teach the fundamentals of determining the country of origin for emerald. Participants will learn the visual, inclusion and chemistry factors that lead to country of origin opinions. Participants will also use microscopes during the lab session to identify inclusions in samples used by the GIA laboratory. After completing this advanced seminar, students will have an understanding of the characteristics that indicate the country of origin for emerald and the complexities involved.
Saturday, 9 Feb, 9 am to 11 am, Coconino Room
Low Temperature Heat Treatment of Mozambique Rubies and Basaltic Blue Sapphires
Low temperature heat treatment of certain kinds of corundum has been a major concern to the industry in the past several years. This two-hour lecture and lab session will focus on the research GIA has done to try to develop more reliable ways to separate these low temperature heated stones from stones that have not been treated. The many challenges to making these separations will be discussed along with the results of research that will emphasise what we can do and what we still cannot do. Participants will use microscopes to examine some of the very samples used in this research and will learn to separate the sometimes subtle changes in inclusions that happen at these temperatures.
Saturday, 9 Feb, 1 pm to 3 pm, Coconino Room
If you are interested in attending any or all of these fee-based seminars, fill out this form and submit it now. Seats are limited. You can also call GIA Admissions at +1 760 603 4001.
Dr James Shigley, GIA distinguished research fellow and a member of GIA's research team, will share insights on important industry developments. His talk will include an update on the GIA laboratory, research efforts at the Institute and other timely topics, which may include the state of the diamond industry and trends in coloured stones.
Friday, 8 Feb, 9 am to 10 am, Mohave Room
The Causes of Colour in Natural Coloured Diamonds
Coloured diamonds have long fascinated both consumers and gemmologists. This seminar will review GIA’s ongoing research into diamond colour and provide an overview of colour-causing factors in natural diamonds. It will also include an in-depth look at green, blue and pink diamonds in GIA Research’s extensive database (dating from 2008 to 2016), summarising research results and the causes of colour in these valuable and rare stones.
Wednesday, 6 Feb, 9 am to 10 am, Maricopa Room
