great video! you seem like honest guy. i alot of youtubers with gemstones , try to advertise their website/stores to purchase jewerly. hard to tell who is honest or fake
I can't thank you enough for this amazing video. I got a ring as jade, but the minute I opened the box I knew it is emerald. Thank God it wasn't glass! based on your video, it seems to be a lab-created emerald.
With pleasure🙂 Thank you Ragnar, I hope it will help as many people as possible to check and distinguish their Emeralds / Green Stones. Let me know what your green Stones are. If you suspect Glass, first look for Bubbles and then see whether you can see curved streaks or zones. Glass usually also has a more homogeneous color, like the test Stone in the Tutorial here. Good Luck and have Fun in testing.
@@GermanGemcutter I was curious about the oil as I was under the impression Emerald was porous. Isn't oil in your Emerald something to look out for as some people place the oil to make them appear clearer than they are from what I understand. Perhaps you could fill me in on what I am missing here.
Fantastic, I'm new to the stone industry., I recently came across some emeralds, I was looking to sell them and now I can imitate your oil method to take close up pictures of them so I can sell them. Thank you
I am confused about the acetone test with emeralds, as most affordable on the market have been treated with resin but are still genuine...would this not ruin the treatment of the stone & it have to be redone?? I ask, because the dyed quartz is hard to tell apart, and would fail a presidium gem test as well :/ thank you!
A viewer asked me if acetone could also be used. You are of course right, acetone can attack resin and partially dissolve them. A test in oil is preferable in any case, so the colored cracks can be seen very well and nothing happens to the stone. Usually strong negative pressure is created to fill emeralds, be it with oil or resin. This means the stone remains stable, but the surface of the fillings could be attacked if they are exposed to acetone for too long. Acetone dissolves colors, the test ultimately depends on what was used for the fillings and how long you expose them to the acetone. A wipe test is preferable to a bath in acetone. A little acetone on absorbent paper or a stick and rub a small area of the surface with the soaked piece, with the colored quartz you can see green color on the stick or on the paper relatively quickly. Acetone test, can destroy a stone, therefore always prefer non-destructive tests.
@@GermanGemcutter awesome, thank you!! Will keep the acetone wipe test in mind, that seems like a much safer method than soaking. Thank you for the help! :)

Sorry for this question just watched this video lately, am a bit behind on the actual oil to use for test is it necessary to use the natural oil we use when cooking
Hi Samuel, no problem, always ask if something is not clear👍 In general, oils have a higher refractive index than air. In theory, any oil can be used. Clear oils are best, simply to get a better view inside the Stone. Some oils also have a strong smell, which makes working with them unpleasant, but it also works. You can use almost any oil. I have only given edible oils as an example, as most people have edible oils in their households.
You can do the same test, even if both materials are beryl, please do some research beforehand on typical natural inclusions in Aquamarine. A little research about possible stones that Aquamarine can be confused with or imitated would be also helpful.
Excellent tutorial. I bought a beautiful 22 karat polished emersld for my wife as s wedding gift and now am exploring business opportunities of exporting swat emeralds from pakistan.

Hey, habe das video sehr genossen!

Edelsteine allein von einem Foto her zu bestimmen ist leider häufig nahezu unmöglich, jedenfalls lässt sich so keine seriöse Bestimmung/Zuordnung vornhemen. Lediglich bei sehr scharfen Nahaufnahmen mit guter Belichtung und neutralem Hintergrund, ließen sich unter Umständen z.B. einige typische Einschlüsse erkennen und man könnte dahingehend eine Vermutung äußern.

I'm deep into Vedic Astrology and this video is a godsend! 🙏 A little bit of UV analysis in the testing wouldn't hurt too, some of them fluoresce, yet are natural, I wonder why..
Thank you very much🙂 Yeah i tested the natural specimens before i make the Video but no fluorescence. If you have a natural Stone with fluorescence it is because of the Oil inside. Most natural Emeralds are oiled because of the Inclusions. The Stones become a better clarity. Justin K Prim has a great Video here on TH-cam "How Emeralds are oiled" if you are interested, check it out👍 If i found some natural specimens with fluorescence i will make a Video.
Interesting, did not know it was the oil that made them Florence, always tough was a chemical reaction within stone. Colombian emeralds from chivor and muzo are said to florect some green some red.
As long as the Stone is clear enough, you'll get a better view inside. You should know the indicators for natural and synthetic Stones of the specific Material. The Hyperion Inclusion Gallery is a good research resource.
Thanks for watching. I used Camelia Oil for this test but just because i have had it available in my household. You can use every clear and colorless oil for this test. Dont forgett some oils smells strong which makes the work with it a little uncomfortable.
Thank you so much! I'll need to buy some acetone tomorrow but the (vegetable) oil trick was fun. I didn't find anything like you showed, but you and I have only just begun :) I was in Afghanistan for a little while and every little camp had a little local 'store', and I got various things knowing it's all likely glass but ... I didn't spend any big monies. Maybe altogether a month's groceries, but for them it was likely a fortune. I have some 'spinel, sapphires, rough tourmaline and emerald, aquamarines', etc., but likely...not. Maybe I'll learn to make some bracelets or earrings for gifts. For now, my fingers are nice and soft and I need to watch your next video!
Thank you for watching and your comment. Glass can be recognized by gas bubbles, swirls, curved lines and a relatively homogenic color. Hope you have some lovely gems / rough gems in your purchases from Afghanistan. There are super beautiful and amazing Tourmalines in Afghanistan, but they are usually very expensive.
I also bought stones in Afghanistan at the bazaar’s. A friend of mine’s favorite is emeralds. I thanked her care package efforts with a fairly large emerald. She had it mounted at one of our prominent jewelers and they told her to to carefully when wearing it and they recently said it was valued around $12 G’s. Believe me I didn’t pay that. I was located on the Pac border.
Try to find straight and/or angular zoning as an indicator for natural Sapphire. I have also a Video of the same Test for Sapphire on my Channel if you wanna see some examples of natural vs synthetic Material. Thanks for watching.
For this Test i used Camelia Oil, just because i have had it available in my houshold. You can use every clear and colorless oil for this test. Dont forgett some oils smells strong which makes the work with it a little uncomfortable.
So to clarify. If I place any Gem, for example, a saphire or emerald into a clear oil, and the stone keeps it's color all through out it, then it's REAL. If not, as you've shown in the video, then it's FAKE. Is that correct.?
@@GermanGemcutter I am glad to let people know how to avoid a scam. I am very new still. I want to learn to cut so bad it's almost a sickness. Lol. I am trying to work out a way to get a basic starting setup for faceting and carving too. I like how you use the inclusions in your work . It is super cool!
Thanks for watching. I used camelia oil for this test. Bought it years ago in a Bonsai Online shop. You can use every clear and colorless oil for this test e.g. Foodoils. Don´t forgett some oils have a strong odor, which can make working with them a bit uncomfortable.
Sir i found 1 ring it has 12 different color stones and 1 big stone is on bottom i showed in jewelry shops they were asking me about 40$ price i refused can i show you on some app or wattsapp

Hi in this Video i used Camelia Oil, but you can use every clear and colorless oil for this test. Don´t forgett some oils smell strong which makes it a little uncomfortable to work with. Thanks for watching.
That was a great walk through fora basic practical test for the non gemologist person in quest for a fair stone . There after clarity color luster etc one has to dedicate time and study - but this practical approach definitely puts the emerald affecionado on the right track ! Thank you ! By the way - an oil examining tray with light below is something one can buy or has to b e self made ? What would you advise someone who wants to travel to -eg - Afghanistan - looking for a couple of stones for himself - should he look at raw stones to cut later or go for the ready cut offers at some respectable as possible local trader ? The uncut earth mined raw stones are safer option to invest or involve its own - different traps and necessary gem knowledge ? THANK YOU -anyway - AGAIN
Thank you for your kind words. I am very happy if this simple test helps you too. I built the "light table" myself from an LED panel ceiling light. In my new studio, I integrated this panel into my work table. I made sure it's dimmable, splashproof, shockproof and has the ability to change color temperature. An LED flashlight is best suited for tests on the go, some also offer a UV function which can also be very useful. A suitable plastic container, transparent or white, is usually found in household food packaging. A white plastic diffuses the lamp's light and makes it easier to examine the stones. As a private person without contact to a grinder, raw stones are usually difficult to sell later. If you are not interested in cutting yourself, it is best to choose cut stones locally. It is often the case, however, that as a "tourist" inferior stones are offered at very high prices. It is best to try to make contacts before you start your journey and to see what offers are made to you. Always remain skeptical at first, no matter how tempting some offers may appear. I have read and heard some reports of experiences where it is usually not worthwhile for private individuals to buy the stones locally. In addition, they must always be familiar with the country-specific export and import regulations and always with exemption limits and fees for any goods imported into their country. Nevertheless, my answer should not deter you and I wish you every success in your travels and adventures.
@@GermanGemcutter thank you so much - trip coming up after we get unpacked our central American house back home . Then comes a new quest . Personally I love emeralds ! I am obsessed with them . My wife's engagement ring i had it in a solitaire cabochon emerald with two smaller matched for earrings .. unfortunately and though I bought 3 for earrings from a known stone wholesaler ( expensive but good quality ) i lost the third I kept for myself and the cabochon of the ring on a day my life and survival was 50 -50 broken about 5 pieces !!!!! Then my wife lost a Ceylon very expensive heart shaped sapphire i had made in another custom ring and finally the one of the remaining emerald earrings ...!!! Bad moon .... I am not superstitious but it gets really costly making jewelry she keeps losing or braking !!!! lol Now i got to find some really nice emeralds matching the color shape and size of the old stones for the empty ring and the single earring ! By the way I kept the pieces of the broken emerald and the larger two pieces are considered for mounting on another design after some re shaping .... I even think a crescent for the smaller piece and small 3 and 2 mm cabochon for the rest to use on my custom bails ... Recycling ...
@@GermanGemcutter I'd love to - given it is obtainable but in three - to maybe - four weeks time as at the moment I am choreographing a moving - means I'm returning home after a 7 year expatriation in the land of "pura vida" name it Costa Rica and the moving became the hardest ever puzzle i am to solve !!!! .With a container of belongings and things ranging from installations to jewelry ready made or in half finished and materials looking to ship them back to Greece -and looking to sell the last things that i can't take along - my car - some restricted wood that haven't got the time to make into legally exported furniture or cabinets and a workroom with power tools of the wrong voltage - need to make sure I am back home first ... I had my last shipment of raw opals to my address in Greece returned to the seller - thankfully holding them for re sending to me upon arrival - as miscalculation of returning date y blame the unforseen ever stalking me delays and no one to legally receive them for me - made the parcels returnable to sender !!! Get the idea ?
Csn I do the acetone wipe test on the emerald I have but it has been fitted in an 8 elemental ring ( copper , iron , gold , silver , bronze etc ..) .Will wipe test not harm the ring ?
Thank you. It is from Lotus Gemology on their Website. Here is a Link to the Inclusion Gallery Search Engine: www.lotusgemology.com/index.php/library/inclusion-gallery
It depends on the Quality of your Stones. If you have Gemmy Quality Emeralds, you will find a very informational Video by Justin K Prim of how emeralds are oiled, here on TH-cam.
Very good question👍 I bought the corresponding stone in an auction for a few euros. But I've also seen a lot of offers for many hundreds of dollars. Maybe someone from the community can help us here. It may have something to do with the size of the stones or the manufacturing process🤔
@@GermanGemcutter I think either way emerald is always worth something. There are many lab-created emeralds that are worth a lot when added to gold rings or pendants. I got a 14k ring with an emerald stone similar to the one in the video for $200! in the auction. I checked outside, in some stores, it was over $500.
In this case it is Camelia oil, but you can use any clear, colorless oil because of the higher RI, which is closer to the RI of the Gemstones. Dont forgett some oils smells, which can make a test a little uncomfortable. Thanks for watching🙂
Thanks for watching. Devices like this can help get an idea of what your stone might be, but I would never rely on it. Emerald is Beryll with a 7.5-8 on Mohs hardness scale. Sapphire is corundum with a 9 on Mohs hardness scale.
You did not present the natural gems as you did with the commercial ones as you should have shown the parallel and perpendicular view of the naturals, The fakes look like glass but what does the natural looks like?
You're right, unfortunately I forgot. Often the look resembles one another in different perspectives(Natural specimens), it is important to always pay attention to color zoning and corresponding Inclusions. In my opinion, the best and freely accessible database for inclusions can be found at Lotus Gemology. The link is in the video description, alternatively search online for "Hyperion Inclusion Gallery Lotus Gemology" Thank you for the kind addition🙂
Due to different types of settings, this can be impossible, everything is much more difficult to see. All you can do is find a good viewing angle to explore the Gemstone, if you can't get it out of the setting. An example, if the Crown or Pavilion of the Stone protrudes over the Setting, take a look from the side, and look that the Stone is in a horizontal position. An assembled Stone can be detect if the crown/pavilion appears colorless. If you have a Ring, put a flat white piece of plastic through the ring so you have a white Background under your Stone, when you look from top.
What if I have a semi translucent stone with a lot of “flux like wispy veils? The fact that it is semi translucent is throwing me off that it is synthetic.
Thanks for watching🙂 Some synthetic materials can have a lot of inclusions too, especially veils. Maybe a research in the hyperion inclusions gallery can help(link in video description). Let me know if you can detect, if those veils are curved, straight or angled.
I don't have any Emeralds to check, but if I ever win the lottery, I at least now know what to look for. Great job, very easy to understand. Thanks German Gemcutter.
yeah sure sounds strange to us😄👍...but some friends, which are not very familiar with Gemstones asked me e.g.: what means lab created...is it a natural stone? Is it natural and/or treated? and so on.
Hahahaha! Sorry for being harsh.. I just wish I can get trained to do lapidary work.. I think its therapeutic. I think we just have different views, I support lab grown gems because they are conflict free. Also Im from an Asian country rich with natural resources and have seen the devastation brought by minning activities. There's that too. This video is really good though, I mean the work done with the fakes is mind boggling.
@@FrancisBalgos Not necessarily. I prefer to cut natural stones, but I also like synthetic stones as a gemstone cutter, there are some advantages over natural stones, the most important one you have already mentioned. I know a lot of pictures and videos of mines all over the world and yes often it is very problematic in relation to nature and certainly much more frightening when you have to watch it live. So you're absolutely right, I think it would have been better to just use the terms natural and synthetic in the video because fake sounds a bit derogatory and that was not my intention to devalue synthetic material. Thank you very much for your reply and Feedback👍
Almost everybody think lab created are fake, because it's created, and in a very little amount of time, when nature make centuries and thousand of years to make gemstone. Conflict are human fault, and whenever even if those labs don't give direct conflict, they are most of them bad for nature and/or climat because of how they work, so it's still a humanity conflict, just a more hiding one. Labs created are called synthetic too, so whatever, in the biggest majority of country, they are called fake.

I get why lab created emeralds are considered fake but at the same time pisses me off when people call them fake because if it’s still Beryl I feel like it should be given a bit more respect for that regard.
Hey Buddy you are absolutely right. I just didn't pay attention to it at the time. Fortunately, some viewers have already pointed this out to me. Thanks for your feedback.
Because it will have negative side affects ever thought about energy real emrald produces ? People use stones also for chemical based properties as it can benefit their health but if the stone is not real how can it give you benefits ? Natural things gives benefit in balanced way(mild benefits) but you reduce those and if lab made emrald instead of inclusion have cracks it will be disastrous
I got the Stones from a larger lot of used Jewelry from a Goldsmith, I bought the Pakistani Swat Emeralds privately from a Collector. If you are interested, you can send me a DM on Insta, Link to my Account in every Video Description down below.
The program is beautiful but fast and will not allow the follower to read the explanation and see the experience of the stone at the same time, either reading or looking at the stone ، F ,J. .
Went into the video with high expectations but I watched it all and it seems you don't even know yourself what the best indicators are for whether it's real or not and are barely even pointing out the differences between the natural and unnatural stones while throwing out a load of buzz words.
I have been gifted a few loose stones in the past and now i can
see what I really truly have thanks to your videos.. thank you lots!

As long as the Stone is clear enough, you'll get a better view inside. You should know the indicators for natural and synthetic Stones of the specific Material. The Hyperion Inclusion Gallery is a good research resource.
this is very helpful thanks
Thanks, i am very happy when my Videos help🙂
Great video! Is it possible too do this with paraffin oil?
Thanks, yes you can use every clear and colorless oil. Paraffin oil is good for this test, it has a RI of 1.467, works well.
Which oil is used to see ??? Please reply
Thanks for watching. I used Camelia Oil for this test but just because i have had it available in my household. You can use every clear and colorless oil for this test. Dont forgett some oils smells strong which makes the work with it a little uncomfortable.
Thank a lot...💯👌 That you replied
When I as a consumer , go to stores trying to buy an earth mined emerald, how can I ask for an oil test?
Thank you so much! I'll need to buy some acetone tomorrow but the (vegetable) oil trick was fun. I didn't find anything like you showed, but you and I have only just begun :) I was in Afghanistan for a little while and every little camp had a little local 'store', and I got various things knowing it's all likely glass but ... I didn't spend any big monies. Maybe altogether a month's groceries, but for them it was likely a fortune. I have some 'spinel, sapphires, rough tourmaline and emerald, aquamarines', etc., but likely...not. Maybe I'll learn to make some bracelets or earrings for gifts. For now, my fingers are nice and soft and I need to watch your next video!
Thank you for watching and your comment. Glass can be recognized by gas bubbles, swirls, curved lines and a relatively homogenic color. Hope you have some lovely gems / rough gems in your purchases from Afghanistan. There are super beautiful and amazing Tourmalines in Afghanistan, but they are usually very expensive.
I also bought stones in Afghanistan at the bazaar’s. A friend of mine’s favorite is emeralds. I thanked her care package efforts with a fairly large emerald. She had it mounted at one of our prominent jewelers and they told her to to carefully when wearing it and they recently said it was valued around $12 G’s. Believe me I didn’t pay that. I was located on the Pac border.
Awesome. THANKS
Thanks for watching
Can i check it with water? As what have 1.33 reflective index?
Dammmm all the info to learn something about emeralds 👍🇦🇷
Thanks for watching
nice work
Thank you
thanks glad i got an opaque real one emits green light in darkness
Try to find straight and/or angular zoning as an indicator for natural Sapphire. I have also a Video of the same Test for Sapphire on my Channel if you wanna see some examples of natural vs synthetic Material. Thanks for watching.
Please make a video on identifying white sapphire
What kind of oil do I use?
can i use olive oil? thanks
Obviously you will need no color, high ior oil to see the true colors
How do you see colors through the colors of olive oil?
Clear and colorless oil works best
Very good video
Thank you
What liquid used for this test?
For this Test i used Camelia Oil, just because i have had it available in my houshold. You can use every clear and colorless oil for this test. Dont forgett some oils smells strong which makes the work with it a little uncomfortable.
So to clarify. If I place any Gem, for example, a saphire or emerald into a clear oil, and the stone keeps it's color all through out it, then it's REAL. If not, as you've shown in the video, then it's FAKE. Is that correct.?
Thanks for your Feedback, have answered your first comment.
Te second piece (square,yellow green ) is material used on ebay for trapiche emerald with lack magic marker used for the division lines.
Thank you for the extra Informations. it is always very helpful, when people sharing more Tips, Tricks and Infos here👍 Thanks
@@GermanGemcutter I am glad to let people know how to avoid a scam. I am very new still. I want to learn to cut so bad it's almost a sickness. Lol. I am trying to work out a way to get a basic starting setup for faceting and carving too.
I like how you use the inclusions in your work . It is super cool!
Thank you for your knowledge, the name of the oil used and how and where I can buy it
Thanks for watching. I used camelia oil for this test. Bought it years ago in a Bonsai Online shop. You can use every clear and colorless oil for this test e.g. Foodoils. Don´t forgett some oils have a strong odor, which can make working with them a bit uncomfortable.
@@GermanGemcutter thankyou so much
What do the assembled stones like in 3:56 look like outside the oil?
I have swat emeralds I will check them now
Thanks for watching
Sir i found 1 ring it has 12 different color stones and 1 big stone is on bottom i showed in jewelry shops they were asking me about 40$ price i refused can i show you on some app or wattsapp
It's very clean and beautiful
Sorry for my late response, i have some trouble with my Internet connection. Yeah you can contact me via DM on Insta or Facebook. Links in every Videodescription down below. Thanks for watching.
hallo, plz, write me the name from kook oil. end wat most do about aston? thankyou
Hi in this Video i used Camelia Oil, but you can use every clear and colorless oil for this test. Don´t forgett some oils smell strong which makes it a little uncomfortable to work with. Thanks for watching.
Excellent, thank you
With pleasure👍 hope the method will help you with your Gemstones🙂
So only way to check at home is by using acetone ?
No Aceton, clear and colorless Oil
That was a great walk through fora basic practical test for the non gemologist person in quest for a fair stone . There after clarity color luster etc one has to dedicate time and study - but this practical approach definitely puts the emerald affecionado on the right track ! Thank you ! By the way - an oil examining tray with light below is something one can buy or has to b e self made ? What would you advise someone who wants to travel to -eg - Afghanistan - looking for a couple of stones for himself - should he look at raw stones to cut later or go for the ready cut offers at some respectable as possible local trader ? The uncut earth mined raw stones are safer option to invest or involve its own - different traps and necessary gem knowledge ? THANK YOU -anyway - AGAIN
Thank you for your kind words. I am very happy if this simple test helps you too. I built the "light table" myself from an LED panel ceiling light. In my new studio, I integrated this panel into my work table. I made sure it's dimmable, splashproof, shockproof and has the ability to change color temperature. An LED flashlight is best suited for tests on the go, some also offer a UV function which can also be very useful. A suitable plastic container, transparent or white, is usually found in household food packaging. A white plastic diffuses the lamp's light and makes it easier to examine the stones. As a private person without contact to a grinder, raw stones are usually difficult to sell later. If you are not interested in cutting yourself, it is best to choose cut stones locally. It is often the case, however, that as a "tourist" inferior stones are offered at very high prices. It is best to try to make contacts before you start your journey and to see what offers are made to you. Always remain skeptical at first, no matter how tempting some offers may appear. I have read and heard some reports of experiences where it is usually not worthwhile for private individuals to buy the stones locally. In addition, they must always be familiar with the country-specific export and import regulations and always with exemption limits and fees for any goods imported into their country. Nevertheless, my answer should not deter you and I wish you every success in your travels and adventures.
@@GermanGemcutter thank you so much - trip coming up after we get unpacked our central American house back home . Then comes a new quest . Personally I love emeralds ! I am obsessed with them . My wife's engagement ring i had it in a solitaire cabochon emerald with two smaller matched for earrings .. unfortunately and though I bought 3 for earrings from a known stone wholesaler ( expensive but good quality ) i lost the third I kept for myself and the cabochon of the ring on a day my life and survival was 50 -50 broken about 5 pieces !!!!! Then my wife lost a Ceylon very expensive heart shaped sapphire i had made in another custom ring and finally the one of the remaining emerald earrings ...!!! Bad moon .... I am not superstitious but it gets really costly making jewelry she keeps losing or braking !!!! lol Now i got to find some really nice emeralds matching the color shape and size of the old stones for the empty ring and the single earring ! By the way I kept the pieces of the broken emerald and the larger two pieces are considered for mounting on another design after some re shaping .... I even think a crescent for the smaller piece and small 3 and 2 mm cabochon for the rest to use on my custom bails ... Recycling ...
@@GermanGemcutter I'd love to - given it is obtainable but in three - to maybe - four weeks time as at the moment I am choreographing a moving - means I'm returning home after a 7 year expatriation in the land of "pura vida" name it Costa Rica and the moving became the hardest ever puzzle i am to solve !!!! .With a container of belongings and things ranging from installations to jewelry ready made or in half finished and materials looking to ship them back to Greece -and looking to sell the last things that i can't take along - my car - some restricted wood that haven't got the time to make into legally exported furniture or cabinets and a workroom with power tools of the wrong voltage - need to make sure I am back home first ... I had my last shipment of raw opals to my address in Greece returned to the seller - thankfully holding them for re sending to me upon arrival - as miscalculation of returning date y blame the unforseen ever stalking me delays and no one to legally receive them for me - made the parcels returnable to sender !!! Get the idea ?
Thanks for all the infos... Good Luck
Lab created emerald is NOT fake. However, its a scam to sell lab grown as natural
Thank you, you are absolutely right. Some viewers had already pointed this out to me and now I pay attention to it.
Csn I do the acetone wipe test on the emerald I have but it has been fitted in an 8 elemental ring ( copper , iron , gold , silver , bronze etc ..) .Will wipe test not harm the ring ?
Do not use acetone! With copper, for example, pitting can occur if the non-ferrous metal comes into contact with acetone.
As a gemologist, new gem cutter and a deutsche learner, I like your channel. I didn’t find the app “Hyperium” (sp) in your links.
Thank you. It is from Lotus Gemology on their Website. Here is a Link to the Inclusion Gallery Search Engine:
www.lotusgemology.com/index.php/library/inclusion-gallery
@@GermanGemcutter It says page not found. I wonder where I can reach it?
Sir how to crack filling emerald,and how to remove black marks in emerald please guide me
It depends on the Quality of your Stones. If you have Gemmy Quality Emeralds, you will find a very informational Video by Justin K Prim of how emeralds are oiled, here on TH-cam.
I would like to see some dark emeralds
So how much is a lab grown emerald worth? like the one you showed
Very good question👍 I bought the corresponding stone in an auction for a few euros. But I've also seen a lot of offers for many hundreds of dollars. Maybe someone from the community can help us here. It may have something to do with the size of the stones or the manufacturing process🤔
@@GermanGemcutter I think either way emerald is always worth something. There are many lab-created emeralds that are worth a lot when added to gold rings or pendants. I got a 14k ring with an emerald stone similar to the one in the video for $200! in the auction. I checked outside, in some stores, it was over $500.
Very useful video. thank you:-))
Thank you 🙂
Which oil pls.?
In this case it is Camelia oil, but you can use any clear, colorless oil because of the higher RI, which is closer to the RI of the Gemstones. Dont forgett some oils smells, which can make a test a little uncomfortable. Thanks for watching🙂
Thank you very much
Thanks for watching
Use one of those cheap moisionitte testing things it'll hit red with Sapphire and emerald I think has same hardness
Thanks for watching. Devices like this can help get an idea of what your stone might be, but I would never rely on it. Emerald is Beryll with a 7.5-8 on Mohs hardness scale.
Sapphire is corundum with a 9 on Mohs hardness scale.
I gave you a thumbs up just for your introduction.😅
Thanks
Great vidio thank you
You did not present the natural gems as you did with the commercial ones as you should have shown the parallel and perpendicular view of the naturals, The fakes look like glass but what does the natural looks like?
thanks for sharing such a quality material
You're right, unfortunately I forgot. Often the look resembles one another in different perspectives(Natural specimens), it is important to always pay attention to color zoning and corresponding Inclusions. In my opinion, the best and freely accessible database for inclusions can be found at Lotus Gemology. The link is in the video description, alternatively search online for "Hyperion Inclusion Gallery Lotus Gemology"
Thank you for the kind addition🙂
I can't take the ones in setting out, how do I test them in the settings please
Due to different types of settings, this can be impossible, everything is much more difficult to see. All you can do is find a good viewing angle to explore the Gemstone, if you can't get it out of the setting.
An example, if the Crown or Pavilion of the Stone protrudes over the Setting, take a look from the side, and look that the Stone is in a horizontal position. An assembled Stone can be detect if the crown/pavilion appears colorless. If you have a Ring, put a flat white piece of plastic through the ring so you have a white Background under your Stone, when you look from top.
What if I have a semi translucent stone with a lot of “flux like wispy veils? The fact that it is semi translucent is throwing me off that it is synthetic.
Thanks for watching🙂 Some synthetic materials can have a lot of inclusions too, especially veils. Maybe a research in the hyperion inclusions gallery can help(link in video description). Let me know if you can detect, if those veils are curved, straight or angled.
Identify gemstones with a magnet
I have made some Videos about Magnetism in Gemstones
7:13 what do you mean by barrel?
The word being used is not barrel but Beryl
That’s the species of stone
Cool !!!
Thank you
I like you ares video
get a chelsea filter
A helpful accessory
I don't have any Emeralds to check, but if I ever win the lottery, I at least now know what to look for. Great job, very easy to understand. Thanks German Gemcutter.
This method/test helps me a lot👍 Hope you can use it one Day😉👍 it also works with other Stones🙂
If it doesn't come from the ground... it's fake...
Lab created don't mean fake just not natural
You´re right!
You lost me when you said lab created is fake just because its not natural.
yeah sure sounds strange to us😄👍...but some friends, which are not very familiar with Gemstones asked me e.g.: what means lab created...is it a natural stone? Is it natural and/or treated? and so on.
Hahahaha! Sorry for being harsh.. I just wish I can get trained to do lapidary work.. I think its therapeutic. I think we just have different views, I support lab grown gems because they are conflict free. Also Im from an Asian country rich with natural resources and have seen the devastation brought by minning activities. There's that too. This video is really good though, I mean the work done with the fakes is mind boggling.
@@FrancisBalgos Not necessarily. I prefer to cut natural stones, but I also like synthetic stones as a gemstone cutter, there are some advantages over natural stones, the most important one you have already mentioned. I know a lot of pictures and videos of mines all over the world and yes often it is very problematic in relation to nature and certainly much more frightening when you have to watch it live. So you're absolutely right, I think it would have been better to just use the terms natural and synthetic in the video because fake sounds a bit derogatory and that was not my intention to devalue synthetic material. Thank you very much for your reply and Feedback👍
Almost everybody think lab created are fake, because it's created, and in a very little amount of time, when nature make centuries and thousand of years to make gemstone. Conflict are human fault, and whenever even if those labs don't give direct conflict, they are most of them bad for nature and/or climat because of how they work, so it's still a humanity conflict, just a more hiding one.
Labs created are called synthetic too, so whatever, in the biggest majority of country, they are called fake.

GOOD INFORMATION SIR
من فضلك وضع ترجمة بالعربية في الفيديوات و شكراً
New subscriber. Love your content. Am from Netherlands. Looking for relaible source to get genuine emerald. Hope we can connect. Thanks brother.
I get why lab created emeralds are considered fake but at the same time pisses me off when people call them fake because if it’s still Beryl I feel like it should be given a bit more respect for that regard.
Hey Buddy you are absolutely right. I just didn't pay attention to it at the time. Fortunately, some viewers have already pointed this out to me. Thanks for your feedback.
Because it will have negative side affects ever thought about energy real emrald produces ? People use stones also for chemical based properties as it can benefit their health but if the stone is not real how can it give you benefits ? Natural things gives benefit in balanced way(mild benefits) but you reduce those and if lab made emrald instead of inclusion have cracks it will be disastrous
Please where can I get the real Emerald ?
I got the Stones from a larger lot of used Jewelry from a Goldsmith, I bought the Pakistani Swat Emeralds privately from a Collector. If you are interested, you can send me a DM on Insta, Link to my Account in every Video Description down below.
I just came across some from Colombia, I know they are real but now I know how to show other that they are, thank you
The program is beautiful but fast and will not allow the follower to read the explanation and see the experience of the stone at the same time, either reading or looking at the stone ، F ,J. .
Thank you for watching and your feedback

Stop your music, it's very disturbing.
Thank you for your Feedback
Look inclusions
Audio is very feeble.
Yeah i am sorry, had some problems with the Audio. I hope it is better now in the last Videos👍
Went into the video with high expectations but I watched it all and it seems you don't even know yourself what the best indicators are for whether it's real or not and are barely even pointing out the differences between the natural and unnatural stones while throwing out a load of buzz words.
Thanks for watching and your feedback
Ooooooo
