Hello all! I just posted 6 full length tutorials on Υουtυbe! One for each gem identification instrument. Check it out. I’m happy to be sharing what I know with you and help you successfully identify your gems. If you’re not actively practicing any of that but you just like my videos, then you’ll like them too. Get to know more about gem testing. Let me know what you think. #gemtok #gemology #peridot #gemologist
