The salary of a gemologist

Jewellery, precious stones and gems are graded for their characteristics in order to certify their value.

Gemologists are professionals who research, analyse and certify different stones using a variety of tools such as software, sizing instruments and microscopes. In May 2009, the Bureau of Labor Statistics categorised gemologists with jewellers, precious stone and metal workers, and reported average salaries based on 23,410 individuals employed in these occupations.


Although there are no standard qualifications for gemologists, many learn the skills of the trade through vocational schools or receive on-the-job training.

Employment opportunities may increase for those who obtain a graduate gemologist degree, which typically applies to certain types of gems such as diamonds. Other credentials such as the Independent Certified Gemologist Appraiser administered by the American Gem Society may also increase employment opportunities.
