I wish to become a graduate Gemologist with GIA. These videos are so informative and I always enjoy watching! I hope I can come study in person, it would be my dream come true :) Thank You!
I have yellow n blue 40 and 47 gram stone not processed natural, respectively stone ..from pader...but don't know how valuable are they ..and where I cn sell them...
An educational institution like GIA, where I trained, should aim to do better than this video. What we see here is a photo album rather than a gemological presentation on the historical locales of sapphires. Poorly done.
