How to Find & Trust a Gemologist

Look for the letters "A.J.P." or "G.G." after the name of your potential gemologist. This signifies that the gemologist is either an "Accredited Jewelry Professional" or a "Graduate Gemologist" as sanctioned by the Gemological Institute of America. Earning these titles requires extensive training and rigorous testing. If you are looking for a trusted gemologist abroad, look for certification by the HRD Institute of Gemology.

Speak to a local jeweler or artisan about where they source their stones. Many boutiques develop close relationships with the artists who provide their products, and these experienced professionals may be able to introduce you to gemologists they use and trust. Even if they are unwilling to reveal their sources, they may give you pointers on where and how to find a trustworthy gemologist.

Consult a local museum or university with a department of geology, mineralogy or earth science. The professors in these departments are likely to come in contact with gemologists in the course of their work. Check the university or museum website and email a professional who specializes in one of these fields. Chances are the person will be glad to help you connect with a gemologist in your area.

Browse a directory of gemologists, and set up a prospective meeting with any promising leads. The Gemologists Regional Directory provides a comprehensive listing of gemologists in all 50 U.S. states and the Washington, D.C. area. Staff at the American Gem Society are required to retest on a yearly basis in order to be as up-to-date as possible on gemology, and members of the American Gem Society can be found through its member database.
