What others have said... "I recently participated in one of the greatest classes of my career on December 3, 2007. I learned a tremendous amount of useful information on corundum. Having attended seminars offered by other associations, I now know AGTA has the highest standards. I appreciate the honor of attending this class and look forward to more. Deborah A. Villepigue "Education is the best weapon against fraud. This class is a must for any gem dealer who wants to know what he or she is buying." Barbara Lawrence |
