What is a gemologist?

A gemologist specializes in gemology, which is the science, art and profession of identifying and evaluating gemstones. To be considered a gemologist, a person must receive a gemologist degree from a professional school or certification program.

A graduate gemologist, or G.G., is someone who is thoroughly trained by the Gemological Institute of America (GIA) in all diamond, gemstone and pearl types. The distinguished G.G. designation at the end of an individual's name is instantly recognized around the world as the mark of a senior professional in the jewelry industry.

With further training and experience, gemologists can also qualify as appraisers.

Beware: There are absolutely no requirements for someone to call himself or herself an "appraiser." Anyone can hang a sign in a jewelry store saying "appraiser" and not be held accountable to anyone.
