GIA Gemolite® NXT
Discover GlA’s most advanced gemological microscope, featuring LED
lighting,
high-clarity optics, and ergonomic features designed for optimal performance and customization.
GIA iD100®
Use advanced spectroscopic technology to distinguish natural diamonds from non-natural diamonds and diamond
simulants in less than two seconds with easy “Pass” or “Refer” reading results.
Experience the beauty and science of colored stones like never before.
Each day at AGTA, our microscope stations will feature a rotating collection of specimens tied to key industry topics—including treatment detection and geographic origin determination for ruby, sapphire, and emerald. As you explore these stones under magnification, you’ll uncover the “chapters” of their stories: their origins, their treatments, and the features that define their identity.
Across the booth, discover curated specimen cases displaying exceptional rough, polished, and mounted gemstones, each paired with its newly issued GIA Colored Stone Report—demonstrating how GIA verifies the true story behind every stone.
Engage with the content through our daily quizzes, offering the chance to win newly designed GIA Colored Stone Reports.
Not attending in person? Participate from anywhere through our virtual quiz, and win prizes from the GIA Store.
Gain hands-on diamond grading skills and practice with professional gemological equipment in a GIA Lab Class. Offered at the historic Alfie Norville Gem & Mineral Museum in Tucson, AZ, these classes satisfy your lab class requirements for GIA Online Diplomas.
It is increasingly rare to come across ruby and sapphire whose beauty and appeal is entirely due to natural processes. During this hands-on seminar, GIA experts provide an in-depth understanding of their various artificial treatments and how to identify them. Through close examination of specimens, participants will learn practical tips and gain a better understanding of why these stones were treated at all.

Demand for colored stone origin determination has grown significantly in recent years. This service is grounded in comparing a client’s gemstone to samples of known geographic origin. Since 2008, GIA researchers have conducted more than 100 field expeditions worldwide to collect reliable rough colored stone samples used for research and reporting.
During this presentation, researchers will take you through GIA’s scientific approach to origin determination.
Join this talk to understand how laboratory testing has become a critical partner to traditional gemological training. Determining beryllium diffusion, low-temperature heat treatment, and geographic origin requires advanced instrumentation found only in modern laboratories. This presentation explains today’s testing landscape, demonstrates procedures inside GIA’s lab, and offers guidance on when gemologists should rely on lab-based analysis.
Join this talk for an inside look at GIA’s field gemology work. For more than 15 years, GIA teams have traveled to mining regions worldwide to collect highly reliable samples for scientific research, a foundation for strong gemological data. Field gemology also offers insight into how gems form, how they are mined, and what they mean to local communities. This perspective helps gemologists understand the full context of a gemstone and address the complex challenges facing today’s industry.
