The Jewelry Symposium to spotlight AI, traceability, and sustainable practices
The Jewelry Symposium (TJS), formerly known as the Santa Fe Symposium, the premier international event for jewellery manufacturing technology, will convene at the Detroit Marriott Troy from 17-20 May 2025, with a focus on cutting-edge technologies and sustainability.
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.

Swiss International Gemlab Launches with Proprietary AI for Precise Colored Gemstone Grading
Swiss International Gemlab promises Faster, More Accurate Certification, Ensures Report Consistency
Three veteran gemologists today announced the opening of Swiss International Gemlab (SIG), a cutting-edge facility leveraging proprietary artificial intelligence (AI) to enhance grading accuracy and consistency for colored gemstones.
Founded by Willy Bieri, Lawrence Hahn, and Matthias Alessandri—senior experts who have collaborated for over a decade—SIG will operate from state-of-the-art locations in Lucerne, Switzerland, and Hong Kong. The lab promises faster results, unmatched transparency, and scientific rigor, insulated from external influences.
SIG delivers a full spectrum of services, including gemstone identification, origin determination, treatment analysis, and advanced color grading. At its core is SIG-AI Assistance, a proprietary system that cross-references analytical data against structured databases to detect anomalies, ensure report consistency, and slash interpretation time.
With a standard turnaround of five business days—plus expedited options for urgent needs—and real-time status tracking, SIG sets a new benchmark for efficiency and reliability in gem certification. The lab will make its global debut at this year’s GemGenève in May, offering on-site services to industry professionals.
