The International School of Gemology offers two different programs of education. The gemologist program is geared toward students who want to learn gemology for personal or professional means but will not be appraising gems. Upon successful completion of the six required classes, a Registered Gemologist diploma will be issued. The gemologist/appraiser program includes six gemology and two appraisal courses. After successful completion of any course of study, a diploma and certification will be awarded in gemology and appraisal.
The Gemology Institute of America offers several different courses of study. Whether the student is interested in just diamond gemology, prefers to specialize in colored gemstones or would to be able to evaluate, grade and value all gemstones including diamonds, there is a training program to meet the student's needs. All programs result in certification and are accredited by the Accrediting Commission of Career Schools and Colleges. GIA is a private, non profit school.
