About Us

The Master Gemologist Appraiser® certification is the most highly respected designation in the Gems and Jewelry appraisal profession. It is awarded by the American Society of Appraisers.

The American Society of Appraisers (ASA) is the oldest appraisal society in the United States. ASA has been training professional appraisers since its precursor, the American Society of Technical Appraisers, began in 1936. Today, ASA is still the country’s only multidisciplinary appraisal society, providing its members the most solid grounding in the appraisal principles that underlie all classes of property: real, personal, tangible and intangible.

In a word, that’s lineage. Because ASA is a non-profit professional society, they explore the principles of valuation with instructors who are leaders in the profession.

Although small in number, Master Gemologist Appraisers are the acknowledged leader in gems and jewelry appraising – Federal agencies turn to them most often to perform the most sensitive assignments.

The Master Gemologist Appraisers® are among those that consumers trust the most for all their varied gem and jewelry needs, from insurance coverage appraisals to estate valuation and liquidation matters.
