Iran has 2 demantoid mines and they are amazing. You can get very large demantoid crystals from BelQeis mountain in Western Iran but they are not gemmy usually.
Thanks, Elmer. I'm glad you are enjoying the lesson. I will do a lesson on Morganite in the future, including an interesting story on how it got its name!
I HAVE ONE! I AM AN AMATUER COLLECTOR and its 3ct [mid-century portguese?? trilliant cut??] I got it in early oughts from a jeweler who got it from a pawned ring he melted down! it took yrs to id bc of my amateur status. i hope to find the value of some of my last gems by viewing ur videos
Thanks for the comment, Erebus. Talk about a cliffhanger, you left me hanging with your comment. It ended with “they are not only more rare….” And then it stopped! Anyway, I appreciate your input. Of course, there are differences in the chemical composition, refractive index, hardness and more. That is how we identify one gemstone versus another. That said, most people would not be able to tell any of that with just a glance. That is why the GIA warns us of making a “sight identification”. This means don’t try to identify a stone without more thorough testing. There is a big difference in a refractive index of 1.9 (yellow garnet) and an R.I. of 1.5 (citrine). My point is this. Unless you are a serious collector, the average person wouldn’t be willing to spend the very high price of an extremely rare yellow garnet when at first glance it looks very much like a much more affordable citrine.
Another great lesson on gems!! I would love to know places to pan for gemstones in the US. An extra bonus question.....what has been the greatest “find” by someone panning for gems?
I have a paraiba tourmaline question. The GIA Identification Report just says Green-Blue Tourmaline BUT there is a note in the appraisal which says: “GIA Gem Trade Laboratory Report #XXXXXXXXX...”This tourmaline contains copper traces consistent with the elbaite tourmaline from Paraiba, Brazil.” Why isn’t that information on the GIA Indentification Report and can I get a copy of the GIA Gem Trade Laboratory Report? Sorry for such a long question but no one seems able to help me. Many, many thanks!! ❤️
You are the best instructor in the world!
Great info.
Glad it was helpful!

I'm studying gemology, and yours so good at teaching about gem thank you Paul deasy. Please do morganite topic.

Absolutely another grate lesson Paul thumbs up. ✌️😎👍
I like mine from Africa with strong refraction, giving more than one color of FIRE! Keep the horsetail.
Based on what I found in the Internet, you can also find Demantoid Garnets in Iran, Afghanistan and Italy as well as a few African nations.
👍💯👍
How many different types and subspecies of demantoid garnets are there and how many different coulors
So this color change topazalite andradite garnet i found near stanley butte is a highly prized stone
Wow I never knew ,,, this !!! Best teacher , thanks Paul “
Dear Paul Deasy Gemstone. Thanks for Nice Garnet information. İ have also one Green Garnet Gemstone 350 Carat in my hand and i like to mutch.
As always, very interesting

Comparing Topazolite with Citrine is a bit strange. The RI and with that the sparcling is way way better and thats why they are not only more rare...

Hi, hi have andradite green garnet,, ,are they demontoid
I have brown garnet
This , im sad to say , is a mineralogically incompetent fellow-
