Welcome to the Gems and Jewelry Discipline Website!

More than a jeweler, more than a gemologist, the ASA professional is the Gold Standard in appraising

The American Society of Appraisers is the oldest appraisal society in the United States.  The 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, giving 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. To our members, it means the ability to sit down with a real estate appraiser or a business valuation specialist, to name two of our disciplines, and understand both the theory and the real-life economics that produce a first-rate appraisal for you or your client.

Because ASA is a non-profit professional society, we explore the principles of valuation as they evolve from basic economic theory and legal precedent in an atmosphere of collegiality and exploration, with instructors who are leaders in the profession.

Although small in numbers, ASA is the acknowledged leader in gems and jewelry appraising – the appraisers Federal agencies turn to most often, for instance, to perform the most sensitive assignments.

Our titleholders (Accredited Member, Accredited Senior Appraiser and Master Gemologist Appraiser®) are among those that consumers trust the most for all their varied needs, from insurance coverage appraisals to estate valuation and liquidation matters.

Three-quarters of a century in appraisal education count when you want the finest service in gems and jewelry appraising. Contact one of our accredited appraisers and you’ll find out that lineage means…excellence in gems and jewelry appraising.

Gems & Jewelry Education

In keeping with ASA Gems & Jewelry’s commitment to the working professional, classes are scheduled with convenience and cost effectiveness as the priorities. The format includes two and a half days of intensive instruction and hands-on practice, followed by a written exam. Our instructors are practicing gemologist/appraisers who breathe life into the appraisal theory with real-life examples taken from their combined experience in practicing gems and jewelry appraisals.
