AI Yourself Calm: Smarter Systems for the Business Behind Your Craft
Tuesday September 15, 2026 9:00am - 10:00am EDT
Most jewelry businesses already have systems. The question is no longer whether to build them, but how to elevate everyone working inside them. AI absorbs the execution layer beneath your team and your craft, so every person, regardless of role, can work faster, think bigger, and produce at a level previously out of reach. The better you and your team become at directing AI, the better your outputs become. It compounds.

This session is not a one-time setup, but a living system you build, monitor, and keep making smarter. You will leave with a framework, real-world case studies, and a Kickstart Plan to begin with confidence.

Mariel Diaz holds Microsoft's Lead with AI certificate and is a Mindvalley AI Mastery graduate. She built these systems inside her accounting firm — and is still finding new ways to apply them.

Diamond Minds: Who Shaped Our Understanding of Diamond?
Tuesday September 15, 2026 9:00am - 10:00am EDT
How do we know a diamond is a crystalline form of pure carbon? How can we say they formed up to 3.5 billion years ago, at great depths within the Earth? We hear a lot of facts, accept a lot of information… but what – indeed, who – led us to these revelations?

In this presentation, Elizabeth will bring to life the key discoveries that shaped our understanding of diamonds through the stories of the brilliant minds behind the research, reminding us that every advance in science is, ultimately, a very human story.

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.

Introduction to Jewelry Forensics
Tuesday September 15, 2026 9:00am - 11:00am EDT
This Hands-on GIA session will be repeated. Space is limited to 24 participants and is first-come, first-served.

Buyers of used jewelry and those who take in jewelry for appraisal or repair go through a process to identify, analyze, and assess the quality and nature of an item. Many know only certain aspects of manufacturing and are only able to recognize a narrow range of certain make traces. GIA has a systematic framework that will guide you in identifying areas to gain more exposure. Through this lecture and hands-on seminar, you will learn “jewelry forensics” basics, including identifying hand-fabricated components, cast components, CAD/CAM manufactured components, and cast-in-in-place gemstones. Attendees will understand and learn a systematic process and recognizing basic traces of manufacturing processes.

Casting 101 for Non-Casting Jewelry Professionals
Tuesday September 15, 2026 10:30am - 11:30am EDT
Understanding the lost-wax casting process is critical for everyone in the jewelry ecosystem – even if they are not bench jewelers or in a casting shop.

Creating Collectors the Crayola Way

Gem merchants, retail owners, staff, and clients all agree that describing color can be difficult. We can see it in our mind, we know the saturation we're seeking, but we can't quite describe it—it's just a half shade darker or lighter or just a tad more purple in the blue, just a touch more pink to the red...
With so many choices of colored gemstones in the world, how does one get it right, every time, when describing their perfect color choice? Join Shelly Sergent, Curator of the award-winning Somewhere In The Rainbow Collection, as she shares her insight into the whimsical yet highly effective color system.

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.

Recent Advances in Laboratory-Grown Diamond Screening Technologies
Tuesday September 15, 2026 4:00pm - 5:00pm EDT
Production of laboratory-grown diamonds (LGD) for jewelry is constantly evolving, introducing new advancements that occasionally alter the properties of these stones. These changes raise the risk of misidentification by trade members using shelf product screening devices (also known as Diamond Verification Instruments), which could lead to reputational damage and loss of trust. This presentation provides a detailed review of the latest screening models and technologies for distinguishing natural diamonds from LGDs. Each method and its features are explored, along with limitations and blind spots identified by Stuller’s research on 20 million screening tests. Additionally, new advancements in HPHT and CVD melee LGDs, and the challenges to current screening methods, will be discussed.
