Registered Gemologist Appraiser

IIJA Registered Gemologist Appraiser Program Required Course List

Hi RJ,
  I am so thrilled and happy to have received my RGA from the ISG. I pray and only hope for the massive growth of your incredible organization. When I started GIA in 1978 the program was nothing in comparison to what you have offered. It is a shame that so many people are unaware of what wonderful things your program offers not just from the standpoint of earning a diploma; also from all of the information you’ve let us with which is an appreciated flood. I still look forward to one day meeting and or working with you in the future. I look forward to you starting an alumni Association as well.
Warmest regards and thank you for everything,
Craig Sperling
