Excellent video! THANK YOU Oliver! I saw over 50 articles & photos about how to distinguish real emeralds and none was explained and shown that clearly and thorough! I have a emerald pendant which was nearly 2000USD a large piece of emerald...I think I was cheated by a seller with lab made! I wish I saw this video before I bought it!
A purist. Thank God. Love this guy. For a long time only Colombian Cr Beryl was called Emerald. Then The GIA was "Bribed" basically to include Vanadium beryl & others by large mining Co's and brokerages. The GIA( self proclaimed benchmark) is politically and monetarily motivated MOST of the time- Not working for for the consumer( the people who pay retail ) Amidst a hundred other reasons can not be trusted and contrary to popular belief; IS fallible. Please keep doing your videos. They helped me a lot as an ameture. I'm sure many others- If you ever have a hard time getting genuine let me know $600 USD pr ct Anyone who would like to keep up on new and shady treatments/gem scams I recommend "Scamologist" on FB. Thank you- long time subscriber
I appreciate all of your hard work and investment into this great informative video!!! I'm new into the Gem collecting world and the information you provided has been exactly what I've been looking for. It's as if you made this video with the intent to educate a person like myself, and for that I hopefully will save my hard earned money. Thank you and I will look to you for more video information on other Gems and the like. Thanks again!!!
Thank you. Great to be able to get a professional tutorial on line. I Liked your vid on ruby too. Emerald is such a weird stone. I've seen included and striated, opaque stones sell for $1k's. If they were tourmaline, I'd throw them away. I would assume that that would be a telltale sign? I also check for almost like a multi swirled machined aluminum look, when looking down through the table into the pavillion. A more common trait of Colombian emerald, as to Zambian. Hard to fake.
Very excellent! My girlfriend & I buy gems on eBay a lot & in my opinion, you have done us both an excellent amount of knowledge & I want to personally thank you! I've been to Mexico twice & if I'm ever there again, I'd love to look you up, learn more & gift you w/a beautiful gemstone! Thank you so-very much! Johnny
very good information about precious stones. more information about fake sellers required and exact price of precious stones to be produced. ..........🌞
Hello Mohammad, Synthetic emerald behave exactly like a natural one. It is a uniaxial crystal that polarize the light and then will react the same under polariscope, refractometer, spectroscope, dichroscope, etc. First clue, as the color of those synthetic emerald come from the chromium (Cr) they usually dope it heavily and then when you check the stone with Chelsea filter the stone will be bright red. But that is just a clue.
Thank you for share this video full of interesting information! I really appreciate your effort to share your knowledge! I hope to see more videos like this, maybe explaining other beryls in deatils like color and typical inclusion and about other gemstones like spinel, quartz (ametrine, amethyst), topaz, corundum (I also saved your ruby video!!) etc.. Thank you very much from Italy for this helpful video!
Thank you! Unfortunately my english is getting worth, I hop people will still understand the message. I'll post this week the small video about natural inclusions you can find in Emerald. Regards
Dear Olivier, Please, can you give me the author's name, and possible other data, like ISBN, of the book Gems you mentioned. So, I can look for it. Thanks, warm regards. Marcel.
It is so well known. I wonder why an European like you does not know it. But, the name is GEMS. The writter is Michael O'Donoghue. It is a famous book and may be easily found at Amazon.com, for instance. I also like the book of Antoinette Matlins.
Excellent video for a layman like me! I have a request? Can you kindly give a similar presentation for rough emeralds. I am purchasing a some rough emeralds but I am confused in regards to a the pricing. Some are super expensive and some are not. How to categorize rough emeralds with regards to their pricing? Can you help? Thank you once again!
It sounds, Mr. Louy, that you hail from Europe. Please, what region of France (Belgium, perhaps?) do you come from, I'm very curious. Don't let the nay-sayers below tell you otherwise - your command (not diction, so sorry) of the English language is to be commended, much as you hesitate to find the correct words most of the time. I have the same trouble also being polyglot. Very informative video, merci monsieur!
I have synthetic emeralds that read as a sapphire on a thermal conductivity tester, they look better than all of these, but I don't know what to sell them as people think synthetic stones are glass
Unfortunately I do not have Jadeite at the lab for the moment. But, yes it would be very interesting as there is a lot to say about the jade group and all the imitations...
Thank you much for your offer, but here nothing is easy when you have to deal with custom office and gemstones. I'll wait until I can get some sample from my side 8) Thank you again. Best Regards
To check if an emerald is synthetic you need a gemological stereoscope to check the inclusions. Some time you can see it with a 10X loupe. There is 2 type of synthetic, Flux melt or Hydrothermal. Flux: wispy veils, transparent crystals or metallic flakes. Hydro: Wavy growth structure, nail, feathers. All that is not easy to figure out if you do not have the experience! CLUE: usually natural emerald will show some typical natural inclusions. Check suizomex under MICROFOTOGRAFÍA to see some.

I have a couple of gems I'm not sure about as I got them from candle companies. But, will emeralds glow green on your hand when you wear them? Would that be a good test to see if they are real?
Hello Olivier, I have been doing some research on emeralds and am facing a dilemma in regards to synthetic emeralds. How does synthetic emeralds behave under polariscope? Are synthetic emeralds dichroic as well? The RI for real emeralds and synthetics is pretty much very close, so it is very tough to distinguish between real and synthetic.
I wonder what is the name of light that made the emerald appeared to be red (the last 3 emeralds)? correct me if I am wrong the name is chelsea filter? (fluorescence) type... many thanks in advance.
They have 1.11ct Emeralds on GemSelect online. They want $265, it's clearity is Si-i1. Now if you go to GemsNy, they are much more expensive, probably because The clearity is VS2 (Very Slightly Included 2) and they are only 1.00 ct. for $650. I just want to buy some emeralds, because before I die, I'd like to own some precious gems. Nice video, thanks (+1 : 190)
Hi, I just got last week to the lab some nice emeralds from Colombia to grade, so drop me an email and I'll send you some pictures and prices about that size of emerald. Keep in mind, the price of course depend on clarity, BUT most of the emerald today on the market are treated to improve that clarity and prices vary greatly depending on that treatment. Some treatment are soft like oil, but some other are more stronger like epoxy resin, with or without color... lab email is servicio@suizomex.com. Regards
Hello, unfortunately I do not have any emerald rough here in the lab. Price will vary a lot depending on the color and clarity of the rough. Of course, the rough can be treated too, so you have to know how to detect it. Some rough could look nice, but would not be gem quality and then maybe very difficult or impossible to cut. Buying rough stones to cut gemstones is not an easy game. More often, you'll lost a lot of money if you don't have the knowledge. Thank you for the question.
Most of the emerald, but not all, are colored by Cr and then you'll see the stone glowing red, or light red depending of the saturation of the color through a Chelsea filter. But, some nice emerald with increasing iron Fe content will diminish the effect. Some emerald colored by vanadium V will show green.
Olivier Louy Some tourmaline colored by Cr will show red too, but they are expensive and mostly sold as Green tourmaline and not as an imitation of emerald. Step 1), ask where the emerald come from. 2) check with chelsea filter and if the stone turn red then it is or a natural emerald or a synthetic one. 3) check the inclusions to make the difference...
Olivier Louy Last word, a synthetic stone, like a ruby, sapphire, emerald, spinel are mostly to clean to be true. If the stone is clean! Ask a gemologist to check it for you before you buy. This especially for emerald. All the emerald on the market today are included and treated, same for ruby, same for sapphire... same for everything that is usually very expensive and sold as inexpensive...
Hi Olivier could you please let me know the author of the book called gems I would like to buy it after your interesting talk on Emeralds and what to look out for. Many Thanks Mags
hi there thnx for da info and i hv many kinds of raw gems i found it in my place mounts and i dont know what gems its can u help me abt that?? and i think i i found some of painite
I hope to get a chelsea filter$ someday. I have a stone I am not sure if it's real because I got it in an unusual way. I would like to have a good idea if it's real or not before I considered having it appraised.
hollo oliver my friend is it true to detect a real emerald you have to put it in water and if the water glows green its real or if you put a drop of water om top it hold and does not disperse. How can i tell if my emeralds are real

Bonjour , es ce qu’une émeraude naturel peut avoir des bulles de gaz à l’intérieur ? Ou es ce que ça veut dire que c’est un synthétique ?

Great video and the french accent definitely helps too...
Oliver do you participate in hong kong jewelry exhibition?

he passed away two years back.His brother posted in another video comment section
You didnt explain how to use the Chelsea filter as you said you would
***** Look through filter at the stone holding the filter 5 cm from your eye with light shining on the stone. Look for red for chrome bearing.
what is
the price one gram of the pure emerald now?
Thank you
