Course Syllabus: Registered Gemologist Appraiser Diploma Program

(Free preview available at the top of the course list lower on this page.)

Course is Currently Available to United States Students Only


The Registered Gemologist Appraiser Diploma program includes the full diploma program in gemology and jewelry appraisal. This program was designed and produced by state licensed insurance underwriters, adjusters, and litigation managers specializing in high value jewelry claims and insurance. The course sections cover the topics of gemology and then the Evaluating Damaged Jewelry and Personal Property Appraisal sections developed after many years of litigation experience. All of our courses have been certified by various state departments of insurance and are based on actual case history of insurance claims in the United States and around the world. There is no other course like this on the market. The RGA program is recognized by the National Association of Jewelry Appraisers and prepares the student for a professional career in the lucrative field of jewelry appraisal and litigation expert. The ISG offers certified courses, trained instructors with the industry’s highest credentials, and a program that has been listed as one of the top gemological education organizations by many industry leaders.

No dues and no memberships required.

Hand’s On Practical Experience with Gemstones and Diamonds You Keep

The ISG makes every effort to make affordable gemology education available around the world. Currently there are major issues with getting gemstones and diamonds sent and returned to most countries. When it is possible to send to some countries, the increased cost in shipping and customs duties has made sending practical packages virtually impossible. As a result we offer the following two systems by which we can provide all students with hand’s-on practice in gem identification that will help you reach a professional level as a gemologist.

20 StudyGem Reference Set plus Certified Diamonds Included with your Registered Gemologist Appraiser enrollment

  • Each Registered Gemologist Appraiser Diploma student will receive a 20 Gemstone StudyGem Reference Set plus two certified diamonds for your hand’s-on study and practice.
  • These include 20 of the most often seen gemstones on the market, and includes natural and created diamonds. Varieties vary by availability.
  • These are sent to you to use for your hand’s-on practice and study. They are not for return. They are yours to keep.
  • International Students: Be aware that you are responsible for all import duties and fees. The ISG is not responsible for any customs duties or fees for sets sent to you. In the event your StudyGem Reference Set is returned to us, you will incur an additional fee to reship the set to you.

Gem Equipment Package $1995.00

Gemology testing tools are required to complete this program. You are welcome to already own your equipment or purchase where ever you wish.

Final Exam

20 Gemstone Final Exam

  • The Final Exam for the Gemology Section is the 20 Gemstone Final where a 100% grade is required on the identification of 20 gemstones.
  • Once you complete the order form, the first attempt at the Final Exam is at no charge.
  • The Final Exam includes 20 colored gemstones sent to a proctor designated by you in advance.
  • Once you complete the identification you will submit your completed identification form and return it and the gemstones to the ISG for grading.

Once you pass the Final Exam…

Once you have successfully completed your 20 Gemstone Final Exam, you will continue to the Appraisal section. Once you complete that section and your Appraisal Final Exam of appraising two jewelry pieces, you will also be listed in the Registry of Gemologists and Appraisers in the Global Claims Associates website to be presented to the international insurance industry.

If you do not pass the Final Exam…

In the event that you do not achieve the 100% grade on the identification of the gemstones, you may retake the 20 Gemstone Final at a fee of US$75.00 for each future retake. You may retake the Final Exam as many times as required with each retake incurring the US$75.00 fee.
