This year’s symposium will expand beyond its traditional focus on metallurgy and craftsmanship to address critical industry issues like responsible sourcing, AI integration, and advanced manufacturing processes.

“We had an unprecedented number of proposals and abstracts for 2025, and we are delighted that many of our respected presenters will be focusing on timely and important issues like sustainability and technology,” says Linus Drogs, TJS Chairman of the Board. “We are grateful to the experts who will be sharing the latest information on CAD, AI, and additive manufacturing (3-D printing), as well as the group of professionals focused on sustainability related to a responsible supply chain and the tracing of coloured gemstones.”

The symposium will feature presentations from leading experts worldwide, catering to a diverse audience of bench jewellers, designers, manufacturers, students, retailers, and press. Among the technology-focused sessions, Scott Bradford of Gesswein will explore CAD techniques and software for enhanced jewellery design, while Jenny Luker of the Platinum Guild International (PGI) will unveil a new platinum alloy. Consultant Anne Miller will delve into the potential of generative AI, and Joseph Strauss of HJE Company, Inc. will discuss advancements in sinter-based 3-D printing.

Sustainability and ethical sourcing will also take centre stage, with Eric Branwaurt of Columbia Gem House and consultant Frank Cooper examining the traceability of coloured gemstones.
