I work as a gem dealer since i was 18, but today, when I watched this video, I learned alot and thanks for giving information and guiding us about the gems and there origins.
Very very informative Presentation & Thank you for Your time!! and I want to take part in the gem trade oneday...time is ticking though lol I try to collect as many specimens as I can to get use to observing to understand and know the stones
Absolutely great presentation. Thank you!
As someone learning about gems appreciate the knowledge shared, the Q&A session was good too
This presentation is just excellent. I learned so much.

Excellent Presentation
Rubies are nice. I prefer sapphires, rubies, and emeralds to diamonds typically.
This presentation is just excellent. I learned so much. Fascinating! More presentations, please!
Sir, do you buy natural burmese ruby, no heated no treated, top quality burman ruby
You can buy all kinds of gemstones( specially Mozambique Ruby , Tsavorite from Kenya) from around the world in Chinafort Gem market Beruwala Sri Lanka.
Beruwala has got some of the worst collections ever. Better go to Ratnapura for higher quality sapphires.
Thank you ! It was a exellent presentation..
thanks your explanation
I wish he could have mentionned what the other gems were made of on the Ruby necklace. Were they worth so much because of the other gems as well or were the other gems only chrystals and the necklace worth so much only because of the 14 carats ruby ? But I know that the necklace with the other gems, do add values because of how good it looks but I wish there would have been more info about the gems so I would know for myself as I am currently learning how to facet sapphires.
Wim, made an amazing presentation. I learned a lot.
Good presentation thank you love of gems and adventure.

do you know why has ruby called ruby?!it has a secret from iranian language!
I'll tell you if you request...
what is a Z sample?
I was wondering the same thing. I believe he stopped at "F" and the "Z" was only there because it meant to be the end of the alphabet. For other openings but not necessarily used. Like he said, he uses his common sense a lot but it leaves us wondering too.
Ok

It is a shame that GIA had done so much work on this rubies, i have a few of them that i have sent for certification and it seems like no one in GIA had follow what was presented in this movie, They have sent my rubies back within a day saying it is all synthetic rubies. HAHA. GIA is a joke to some customers and they are making many mistakes then they don't even correct them. I will never use GIA again in my life.
what about GIA errors between rubies and sapphires? also they make many mistakes with emeralds and other precious stones. I think this lab is too overrated
Ok
