Frontiers in Colored Stone Origin Research: Jade, Opal, Demantoid, and Peridot
Tuesday September 15, 2026 9:00am - 10:00am EDT
This GIA session will be repeated.

Geographic origin and traceability are at the front of everyone's mind in the gem and jewelry industry. Everyone would love to know where all of their gemstones were sourced and by whom. Unfortunately, it takes a huge amount of research to develop new origin services, and so most gem labs limit origin determination to a small number of important stones. Over the last 10 years, GIA has been scientifically investigating several new materials, and over the last year, has launched 4 new origin services for jade, opal, demantoid, and peridot. This lecture will lay out the scientific basis for geographic origin determination and discuss the research that goes into developing a new origin service.

Colored Stone Treatments in the 21st Century
Tuesday September 15, 2026 10:30am - 11:30am EDT
This GIA session will be repeated.

Untreated vs treated gemstones have very different market values, which require the disclosure of treatments to be crucial. From initial discovery to showcasing the treatment's overall effect, this presentation will explore some of the most significant treatments introduced into the market in the 21st century. Gemstone treatments are not going away, which means educating oneself on them is an important tool for anyone in the trade.

AI's Next Role in Jewelry Design
Tuesday September 15, 2026 2:30pm - 3:30pm EDT
This GIA session will be repeated.

Generative AI is moving quickly from a novelty tool for inspiration toward a practical part of the jewelry design workflow. This session explores how today’s AI platforms are being used to create more realistic jewelry concepts, test material and proportion accuracy, and support the development of 3D design assets. We will look at where these tools are already helping retailers communicate ideas more effectively with clients, as well as where they still fall short of true manufacturing readiness. Attendees will leave with a clearer sense of what AI can do today, what is still hype, and how to evaluate these tools without compromising the craftsmanship, trust, and artistry at the heart of fine jewelry.
