National Association of Jewelry Appraisers (NAJA) was founded in 1981 on the premise that the specialized field of gem and jewelry appraising was an area that was long overdue for representation on a professional basis. The Association's primary purpose is to recognize, and make available, the services of highly qualified, informed, experienced, independent, and professional appraisers of gems and jewelry to those members of the public requiring such expertise. In addition, NAJA seeks to promote the trademark and professional designations earned by our members and to make available continuing educational materials in order to ensure that they are among the best informed appraisers in our industry.

The Accredited Gemologists Association is an independent, international nonprofit organization dedicated to the following practices.

• Gemological Education
• Research
• Identification & Evaluation of Gem Materials
• Development of Professional Standards of Analysis, Practice & Ethics
