- What makes an emerald an emerald and not an aquamarine? Gem-A tutor, Lily Faber FGA DGA, presents this webinar on gemstone species and varieties, providing an overview of the well-known groups beryl, corundum, garnet and quartz. This webinar also covers:
- Chemical Composition
- Inclusions
- Causes of Colour
- Optical Effects
This webinar was created as part of a weekly series of webinars known as Gem-A Live.
I wasn't expecting to stay for an hour-long webinar on gemstones, yet here I am at the end! The power of pretty shinies, perfect pacing, and incredibly easy-to-understand explanations/diagrams/examples compels me!
😍🙇🏿♀️
This video has completely changed my perspective on inclusions. I always saw them as flaws, but now, I appreciate them so much more for what they tell you and see they can actually make the stone much more desirable and beautiful. Thank you!!
I am literally rewatching this video over and over again. You’re awesome, truly!
I was roped in for this entire lecture. Thank you for making this information so interesting and digestible!!
شكرا جزيلا سيدتي .

This was interesting and informative ,Lily. I've been looking for such a video on RUclips, to learn more about Gems, their Types, formation and composition. Thanks for sharing.
Umm hi lol l k I’m iii
I don't know how I ended up watching this video, but it was so well done that I have sat for the whole hour and really enjoyed it all. Well done 👏
6.58K Sub's and over 115K views. Lots to learn. Great presentation; glad this channel showed up in my scroll.
Excellent video. Thanks for posting.
It is very refreshing to find such a quality content offered on RUclips. Excellent choice of relevant facts, sound understanding of concepts, and perfect pace and clarity of presenting it all. Thank you!
Thank you for this! What an education! I dug for garnets in Idaho in 2019. TOUGH tough work. Hessonite, looks like whiskey and water mixed together. LOL

I hate that the subtitles are misaligned with the speaking. Please fix that, this is such an awesome lecture and that really makes it so hard to follow
Informative and very scientific.
These are some of the best lectures on RUclips
Truly enjoyed this! Thank you!
Love this so much! Wish you all would make this a series and cover other species! I’m interested in feldspar, specifically labradorite! So beautiful.
I love this video! So informative the instructor is very engaging. The section on Garnet is everything! 💯
This would have been an extremely useful presentation to watch when first learning i had such a passion for gemology and geology...!
Well, this video is a true gem!
Puns aside, very well made and explained, perfect pace, clear content: thank you so much!
Great job. Thanks!
I learned a lot! Thank you so very much!
Lily you did an amazing job of explaining this aspect of gemology. Really enjoyed the seminar, quiz and the questions at the end.
Thanks again to Gem A 💎
This is an excellent webinar, thank you!
Thank you ❤️ for sharing .💐
I use crystals for Spiritual & Healing work , and found my knowledge lacking in the varieties of the various stones & crystals .
This has been a most informative video .💐 Thank you , ❤️ again .
Namaste 🙏❤️🙏👍🙂
Great video. Usually I'm a little bit critical of these type Vids. You know your stuff. Subscribed. Look forward to more.
I really enjoyed this, thank you
Very informative. Thanks for your time and knowledge.
Awesome thank you for being so clear on what is what with these gemstones! I am a complete newbie, which will become more obvious as I open my mouth,I'm sure. So apologies in advance! The information can be varied,depending on the source,I'm discovering! So thank you for this instruction that holds to consistent standards. You have taught me more in the course of this video than I was able to glean from multiple books! Also it was great to hear the names of stones and their variations pronounced correctly. As I have only been learning from books up to this point, and I have discovered that pronouncing these mineral names does not come naturally to me! Lol! Certainly,without doubt, you have saved me from ridicule,going forward. I can just imagine the embarrassment I would have faced,if I had referred to a cabochon as a caw-bo-chawn!! I shudder! So thank you,sincerely!
Amazing information about recognition and comparison of gems, thanks for sharing.

In the very beginning you said those not underlined don't have variety. Explain why the various colors of topaz (white, imperial, London blue etc.) are not variety. This seems to be an error.
Thank you so much!!!

About emerald if a berylium is mint greenish, not dark green. So not esmerald colour like. More like a green auquamarine but a light minty green? Is it still considered an esmerald?
Wouldn’t inclusions in diamonds beca negative unlike some other stones?
Thank you. Excellent presentation! (I understand it was long and hard lesson for you also...)

30:00 Garnet discussion begins.
Ummm... Garnet is a GROUP, not a Species. Feldspar is a GROUP, not a Species.. how could you get that wrong?
48:19 According to the G.I.A., any Quartz that has needles of Actinolite, Tourmaline or Rutile in it is called Variety: Sagenitic.
Calling Quartz "Rutilated" or "Tourmalinated" is using a TRADE NAME, and therefore inaccurate. This mistake that would make a student fail a G.I.A. 20 Stone Final Exam... what more will they say that is incorrect?
