I want to tell you this video has changed my LIFE. Hard to imagine. I am in my third week of colored stones at GIA. After passing my 5 Stone for Graduate in Diamonds I was feeling more confident and positive starting gems. That quickly changed and my fear of falling behind because lack of/ non-existing VISUAL Instruction was not available. Your knowledge and skill is EXTREMELY appreciated! Again, thank you. I hope to find more videos on particulars of Gem Identing.
Am very new to this, but picking up gem collecting as a hobby. Have decided that it's time I was able to test the things I'm purchasing so I can have confidence as to what they actually are. Greatly enjoyed this presentation, Mr. Hodgson. One of the best training videos, of any kind, I've ever viewed. And I'm a certified trainer in a completely different field, myself.
Many thanks for your kindheaкted attention for the people who are begginers in gemmology. Really great work!! Many thanks!! Sergio (Saint-Petersburg, Russia)
Great instructional video! Some uses of testing equipment such as the polariscope in books I own are hard to understand, your videos are a great resource!
Wow, thank you so much for the uploaded video of the whole explanation of single versus double refraction under a polariscope. I couldn't make sense of how it was done when I don't have the equipment myself at home because of online learning, but it made me understood how I will test it once we're allowed to be back on campus.
Thank you SO much! Again another great informative video. I Just received a polariscope for father's day(hobbyist). I've been relying on RI , SG &old microscope to help me identify mtrls. With isotropic gems you mention opals. (generally) Does this include the crystal opals? I have a nice 3 ct "water clear" Ethiopian crystal opal that is not showing this effect. Everything else is right on but the polariscope. Getting diffused light w/ No flash or banding. Any ideas? I guess maybe i'll look into financial aid & sign up for those GIA classes I been talking about.So cool. Thanks again . Rob T
Thanks for taking the time to make this tutorial! Very good, I really appreciate it :^) I am looking into gem certification in the future through IGS. So exciting to learn about gems.
Thanks so much for an amazing awesome video. I give you a thousand thanks for such awesome video, made with such practical and didactic illustrations. I wish all the best, health, love, prosperity and fortune. God Bless you.

hello have a nice day What are the most important devices that can be purchased to accurately determine the type of gemstone. I work in selling gemstones, I don't want expensive devices because I can't buy them Thank you all
i am gem dealer in africa and to the arabic golf so it is video will learned me bat i don't know how to clean the stone opal can u help me of that thanks
Interesting video, though you could possibly use some proofreading beforehand. I'm sure you meant 'birefringence', not 'biofringence', though 'biofringence' does sound interesting in and of itself (life forms refracting light). Also, it's a 'polarizing' filter, not a 'polaroid' filter. The more accurate you are with your presentation, the more veracity you manifest in your vocation.
Very informative and detailed video with a soothing balanced voice. Thank you
