About Us

National Association of Jewelry Appraisers (NAJA) is dedicated to promoting stringent quality standards for gem and jewelry appraisers. The association was founded in 1981 on the premise that the specialized field of gem and jewelry appraising deserved representation on a professional basis. The NAJA fulfills the need for an appraisal organization focused solely on the specific value factors inherent in gems and jewelry, that were not being addressed sufficiently by the multidisciplinary appraisal associations of the day.

Four decades later, NAJA remains devoted to advancing professionalism in the field through education, training, and peer support. The leadership structure starts with the Executive Director, and supported by Associate Directors. The association prides itself in this streamlined structure, which facilitates quick responses to the needs of our membership, the jewelry industry, and the public.

The association’s primary purpose is to serve the public’s trust by supporting, educating, and promoting highly qualified professional gemologist appraisers with expertise specific to the assignment. In addition, NAJA works to promote the trademark and professional designations earned by our members as well as to develop and offer continuing educational materials in order to ensure that each member has the opportunity to be among the best-informed appraisers in our industry. 

Our goal is to promote professionalism among our members as well as the industry as a whole. NAJA membership provides reasonable assurance to clients that their appraisal report is prepared with professional skill and integrity. The National Association of Jewelry Appraisers is the only appraisal association in the United States that devotes itself solely to the appraisal of gems and jewelry. All of our energies focus on these subjects, which are updated with new information as it becomes available.


The NAJA conducts various programs designed to serve the interests of both its members and the public at large in matters relating to appraisal theory and valuation science. Major elements of this program include:
