The National Association of Jewelry Appraisers (NAJA) has announced the 63rd ACE© IT Winter Conference will be February 1-2, 2025, at the Tucson Convention Center in Tucson, AZ.
The Winter Conference has a major distinction in that it focuses on gemological product knowledge. For this program, NAJA Executive Director Gail Brett Levine worked to organize the conference in connection with the AGTA GemFair Tucson. “We are excited to present this conference in connection during the Tucson event,” said Levine. “Access to the AGTA’s GemFair provides an excellent opportunity for us to integrate what we learned in the classroom and taking it to the show floor.”
NAJA is pleased to have both new, as well as a host of member favorites, experts from the gemological fields joining for the exchange of educational information and professional development. The weekend features hands-on workshops, presentations, exhibits, networking and relationship building opportunities as well as plenty of Q&A – all designed to achieve the conference goal: provide new information and insights that support and enhance attendees in their professional appraisal practices.
