SO WHAT’S UP WITH ALL THOSE INITIALS?
ISA CAPP is the highest appraisal designation offered by the International Society of Appraisers and was earned by completion of extensive educational requirements, a comprehensive examination, hundreds of hours of documented appraisal experience and the submission and peer review of both self-contained and summary appraisal reports. ISA is the only appraisal organization exclusively focused on the appraisal of personal property. There are, as of 2008, fewer than 20 appraisers in North America designated ISA CAPP with a specialty in Gems and Jewelry. This designation must be “re-certified” every 5 years by passing a 5 hour examination, documenting extensive professional development credits and hundreds of additional hours of appraisal experience.
ICGA is the highest appraisal designation of the American Gem Society and was earned by completion of the same courses, experience, tests and peer reviewed appraisals that are required of retail Certified Gemologist Appraiser members of AGS with some additional requirements. These additional requirements include the necessity to document extensive professional development credits, appraisal experience hours and submission of additional appraisal reports for peer review every 5 years. Further, the ICGA member must complete the 3 APPA courses and pass the comprehensive APPA examination. The ICGA member must have an AGS Accredited Gem Laboratory and pass the highest level of the annual re-certification examination expected of all AGS members.
CSM is the second highest designation offered and the highest designation currently held by any member of the National Association of Jewelry Appraisers; the highest designation, CMA, has never been awarded in the history of NAJA. This designation was earned by the accumulation of “points” based on education and experience and the successful completion of a comprehensive examination on appraisal theory along with submission of a self-contained and a summary appraisal report for peer review. Annual recertification is based on documented additional professional development credits.
APPA is the designation conferred by the completion of the Jewelers Education Foundation’s Advanced Personal Property Appraisal courses and successfully passing the 4 hour examination which covers the contents of all 3 courses. This designation is required by AGS as a prerequisite for the ICGA title. These courses are primarily focused on the legal underpinnings of appraising and detail the laws and regulations with which an appraiser must be familiar in order to protect his client both from and during legal proceedings. There is no recertification requirement for maintaining the APPA title.GG (GIA) is the highest gemological title conferred by the Gemological Institute of America. It is earned by the completion of the courses and practical lab sections prescribed by GIA along with passing grades on the comprehensive examinations. This is strictly a gemological designation indicating expertise in the identification and grading of diamonds and gemstones. GIA doesn’t teach appraising or appraisal theory so just because someone is a GG (GIA) that doesn’t mean they can or will competently appraise your jewelry. There are no recertification or continuing education requirements for maintaining the GG (GIA) title.
