I just got interested in gemstones, while looking for a sapphire ring for my daughter. Now I am fascinated with the whole subject of gemstones. Thank you for this video! So far the best one regarding natural vs synthetic! I like your German accent, I’m German myself, living in Southern California. 🇩🇪💍💜💎😊
This was an amazingly helpful video. It helped me immensely to decide what to send off to get certified after humming and hawing for months after two small town jewelers said couldn't possibly be natural sapphires after simply taking a quick peak with a loop. Though I had to unmount them from the rings, it was well worth it. Thank you so very much!!! I look forward to digging into all the rest of your videos.
Благодарю! Прекрасная работа ! Спасибо большое за знания! Вы сделали мой день! И сэкономили кучу денег 💰) Благодарю вселенную, что есть такие люди как Вы!!!
I try to make sure the color zone is not just "close to the pavilion" but rather directly "in the culet" to ensure maximum distribution of the color throughout the cut gemstone.
Great video and more importantly, great pacing (see my reply to my feedback on a previous video). Very informative for a newbie like myself and rest assured, I will be sticking around for lots more. So thank you for taking the time to pass on you knowledge and for taking onboard my comments on pace. Very much appreciated all-round :-)
Straight and angular zoning(up to hexagonal) is an indicator for natural specimens. Curved zoning, homogenic colors, adhesive and bubbles are often indicators for synthetic Materials or Simulants.
@@GermanGemcutterthanks so much ! ;) helped me loads i found out my stones are real since straight color zoning is 1000%natural wow to you an your videos🎉 thanks again friend.
Great video- it would have helped at the end to separate the synthetics from the real ones- just made two piles so we could review those differences- thanks 🙏
Thanks for this wonderful Video. I am wandering how likely will i be permited to execute your tests at the sellers place? Have you got experience to share on this issue?
Thanks for watching, good Question. One option would be to take a small sealable plastic container filled with oil, a good flashlight, tweezers and magnifying glasses. If the plastic container is clear, place a sheet of white paper between the lamp and the container for better light diffusion.
Hello Great videos and good advice. I looked on the internet for kamelien oel, camellia oil and they all have some color while yours looks white.can you explain this please? And where is a good source to buy it in usa. Please asap,since I might have to return the stones I bought. Best Brigitte
Hi Brigitte, i have bought it many years ago in a Bonsai Shop. It is traditional used to protect equipment such as scissors from rust. You can use nearly every other clear and colorless oil. The individual RI of oils can be found online. Dont forgett some oils smells strong which makes the work a little uncomfortable. I have also used a clear foodoil for example. I used the camelia oil only because i have bought enough and dont need it any longer for Bonsai Equipments. Thanks for watching
Thank you for your answer. Would liquid coconut oil at 1.43-1.46 RI be okay for rubies and sapphires? I think they are fake but look quite beautiful and were inexpensive from Etsy in India.They claimed to sell only natural stones and even gave a card from a gemologist that states that they are sapphires and rubies, but there are no inclusions. I wonder what the material could be. Glass, leaded glass, crystal,rhinestones? I have no idea. Does anybody have experience with this? Cheers Brigitte
In general, i consider Lab created Sapphires to be synthetic. It's good that such syntheses exist, they combine tue perfection of all properties, protect the enviroment and are affordable. They only become Fake once somenone tries to sell them as a natural Gemstone. Thanks for watching🙂
I’m just going to point out that even at the wholesale gem shows BETWEEN DEALERS scams happen! I talked to one of the dealers and he said he had boughten a stone from another dealer there and it turned out to not be what he said it was and ohh was there some bad blood- they are in litigation now- so don’t think for one minute that it can’t happen to you. The best thing is to really know who you’re buying from and if it sounds too good to be true, it is.
Pretty sure there's a video online where the guy shows how synthetic Ruby will dissolve in nail polish remover. Dissolves completely in acetone. Probably the simplest way to see if you have a real Ruby or not.
@@GermanGemcutter Forgive me brother, but I thought that resin filling was generally for Emerald? But I guess all gems could be filled. I do know that acetone would disolve the filling, and whatever synthetic gemstone composition material along with it. Thank you so much for your reply have a good day man
Yet another very intressting and informative Video,, it is shocking the lengths unscrupulous dealers go to to con people, I have learnt so much from your videos Micha, thank you!!! Do fake and simulated corundom floreces under uv light?
As far as I know, the synthetic corundum is UV active, I'm not sure if every color of it is UV active🤔 Synthetic spinel is also UV active. Many years ago a guy told me that some natural blue Sapphires can also be UV active. I later talked to an old Goldsmith about it, he had a lot of natural Sapphires collected from old gold jewelry and he tested it with me and yes, he had a few natural specimens that were UV active. So always be careful with just one test, several tests are usually required to determine if a Gem is natural or synthetic. It is always better to do different tests. With the test in oil, a lot can be identified or excluded, but almost 100% security is only possible in one of the large laboratories. They have the equipment to examine all possible properties. Nevertheless, the test with oil or with UV is always a very helpful, easy and cheap way of making a selection in advance. Testing a Gemstone with UV light is also very interesting ... Thank you very much for your kind words👍
@@GermanGemcutter thank you Micha.. Yes I have some raw natural blue sapphire, which do florece under uv, also I have Ruby's from mogok which are very vivid under uv, I have a lab created spinel which does not , The oil trick you showed us is very useful, thank you, Look forward to your next video very much
Its tough to find accurate information about synthetics.. after hours and hours of research I have discovered some truths that piss the jewelers off something fierce
There is a difference in the crystal system, iolite grows orthorhombic and sapphire grows hexagonal. In addition, you have to take a closer look at the typical inclusions of Iolite. Thanks for watching
Great video. I was trying to buy some camellia oil but noticed that most of them have a yellow colour while yours looks white. Can you please explain? Where can I find it in usa? Thank you.
Hi Brigitte, i have bought it many years ago in a Bonsai Shop. It is traditional used to protect equipment such as scissors from rust. You can use nearly every other clear and colorless oil.

Hi Teresa i just used it 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. FYI: The Camelia oil i bought years ago in an online shop for bonsai equipments.
The Oil was Camelia Oil, i used it just because i have had it in my household. You can use every clear and colorless oil for the Test. Don't forgett some oils smells strong which makes the work with them a little uncomfortable. For the best result you can select an oil with a RI close to the Material RI you plan to test. Refractive Index of Oils can be found online. Thanks for watching.
It depends on the tester itself, some electronic testers have a fine enough scale, but in general i wouldn't suggest using a diamond tester for colored gemstones. As i shown in the Video such doublets or assembled stones have only a thin layer of the Material on top, that they try to imitate.
In this Video i used Camelia Oil. But you can use every clear and colorless Oil for this Test, also the one you mentioned. Dont forgett some oils smells strong which makes the work with them a little uncomfortable.
Yeah you can also test Quartz with this method. Try to lay the focus on the typical Inclusions like fingerprints or tiny mineral Inclusions(needles, crystals) look for color zoning, often you can find some straight and/or angular growth patterns in natural Quartz. Another helpful Test, if you have enough experience, is to check the Stone in good light. Often purple CZ looks like Amethyst. CZ has a much higher Dispersion(0.065) than a natural Amethyst(0.013) so if you see a lot of Fire(many small points of light in the colors of a rainbow) it is a CZ.
Thanks for watching. I used Camelia Oil but only because I had it in the house at the time. You can carry out the test with almost any oil. It is important that it is clear and colorless. Please note that some oils have a strong smell, which can make working with them a bit unpleasant.

@@GermanGemcutter But I am worried if this angular ink line can be a sign of heated blue sapphire. Is it true ? That the stone is real but it's heated ?
Very confusing video. 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.?
It was a japanese Camelia oil from a local Bonsai Shop. It is used to care for the tools and protects against rust, but you can use every clear and colorless oil, also food oils for example. You can find lists online to check the specific RI of different oils. Higher RI works better, but dont forgett some oils smells strong which makes the work a little uncomfortable.
It is unfortunate that the sapphire I want to test is set in a ring. Will not be able to view stone from side view. Will only be able to see top & bottom 😢
Unfortunately, depending on the setting, it can be difficult or impossible to take a closer look at the Gemstone. Well I hope you can find indicators of natural or synthetic with top and bottom view. Good Luck with your Sapphire.
Thank you for watching. It is Camelia Oil(used it just because i have it available in my household) but you can use every clear and colorless oil for it e.g. food oils. Don't forget some oils smells strong which makes the work with it a little uncomfortable.

Same Method(use a clear and colorless oil) and you will get a much better view inside the stone. Especially with some raw stones it is difficult to recognize something, then it only helps to cut or polish one or better two surfaces (opposite). Of course, this is not always possible. In general good lighting helps a lot. A flashlight with small selective lighting can also be very helpful for this test, to spot inclusions in gems and raw stones.
but in minute 7:16 you said that, not perfectly cutting gemstone of that sapphire, so i think this is depending one of things the matter terms condition shape cutting gemstone 🙏
In this Video i used Camelia Oil. But you can use every clear and colorless oil for this Test e.g. Foodoils. Remember, some oils smells strong, which makes it a little uncomfortable to work with.
In this case i used Camelia Oil just because i have had it available in my household but you can use every clear and colorless oil for this test. Don´t forgett some oils smells strong which makes the work with it a little uncomfortable. The best results you´ll get with oils which RI is as close as possible to the Materials RI you plan to test. Refractive Index for Oils and Gemstones can be found online. Thanks for watching
Thanks for watching, it is Camellia Oil, but in theorie you can use any Oil, colorless and clear is best. The closer the RI of the Oil to the Material you wanna examine, you become a better view inside the Stone. With this Method whitout a Microscope, you can also use for example a simple Foodoil. Dont forgett some Oils can smell strong, which makes it a little uncomfortable.
@@GermanGemcutter I have a free magnifying camera app on my phone with 60X zoom is that useful? what kind of oil is Camelia Oil and where would you buy it if any oil will work would mineral oil do like the clear baby oil type Thanks
@@tonylohi3685 Hello, I apologize for jumping in. I had the same question but I remember someone saying 'grapeseed oil'. But I like your baby oil idea too. Do Both! Re lens, since I don't have anything but a loupe, I like your mag'yg app too. Do it all, compare - do a video too :)
@@mfb6310 No problem bro I live in Finland its hard to find any kind of chemical because of the greenies, just basic things . I cant even find anyone who does gold plating. The camera app is free it can make the tiniest gem look supersized Ill give you a tip they guy with only a loupe but a passion and as your probably not a competitor where to find the best gems dirt cheap is Chanthaburi Thailand there's a lab there that's GIA trained, Ive also checked them out a couple gems with GIA and 100% right on but that's an expensive test Ill save you from. For the big rocks India is good but very risky a lot of conmen, but I have picked up a couple huge sapphires that made up for all the fakes, Investigating the sources will save you a lot of headaches, money and allegations of fraud. Some of my best rocks I got off Ebay 2nd tip look for positive reviews in German because they are the best,
@@tonylohi3685 Oh. Sorry, we've got many meddling Nannies, as well. Grapeseed oil is a cooking oil, though, that shouldn't be a bother! But if so, wow . And no, I'm def'y not a competitor. I was with the troops in AFG as a civilian, and visited the little haji shops at different camps. After a few years, I'm sure I have a colorful collection of likely mostly plastic or glass, but it's all in the journey, right? I had fun trying to look smart, though, looking through a loop and groaning appropriately. Every once in a while, I bring out the pile and try to learn what to do. I'm ready to just see if they'll melt. You sound like you have learned a lot too! And I like your tips. I worked with men from India - they tell me the businessmen are the biggest penny pinchers! Regarding 2nd tip - I love. I have forgotten most of my german, but I'm not surprised at your tip at all. Thank you so much, Greetings from Michigan.

Fake indicators:

2.curved zoning, homogenized color;
3.curved zoning with bubbles.
Is that all?
Straight and angular zoning(up to hexagonal) is an indicator for natural specimens.

How can I contact you? Will like to send you a sapphire video and see what you think.
Best way to contact me is via DM on Instagram, all Social Media links can be found in every Video description. Thanks for watching.
how can you test with raw sapphire
Same Method(use a clear and colorless oil) and you will get a much better view inside the stone. Especially with some raw stones it is difficult to recognize something, then it only helps to cut or polish one or better two surfaces (opposite).
Of course, this is not always possible. In general good lighting helps a lot. A flashlight with small selective lighting can also be very helpful for this test, to spot inclusions in gems and raw stones.
but in minute 7:16 you said that, not perfectly cutting gemstone of that sapphire, so i think this is depending one of things the matter terms condition shape cutting gemstone 🙏
100% correct
skip the first 4 minutes and watch 1.5 speed
Saving lives thank you and you are right about the speed 👍🏾
Where do you buy your gemstones to know that they are real?
From reputable rough stone dealers

What oil is that?
In this Video i used Camelia oil, just because i have had it available in my household. You can use every clean and colorless oil.
What type of oil ?
In this case i used Camelia Oil just because i have had it available in my household but you can use every clear and colorless oil for this test. Don´t forgett some oils smells strong which makes the work with it a little uncomfortable. The best results you´ll get with oils which RI is as close as possible to the Materials RI you plan to test. Refractive Index for Oils and Gemstones can be found online. Thanks for watching
What kind of oil?
Thanks for watching, it is Camellia Oil, but in theorie you can use any Oil, colorless and clear is best. The closer the RI of the Oil to the Material you wanna examine, you become a better view inside the Stone. With this Method whitout a Microscope, you can also use for example a simple Foodoil. Dont forgett some Oils can smell strong, which makes it a little uncomfortable.
@@GermanGemcutter I have a free magnifying camera app on my phone with 60X zoom is that useful? what kind of oil is Camelia Oil and where would you buy it if any oil will work would mineral oil do like the clear baby oil type Thanks
@@tonylohi3685 Hello, I apologize for jumping in. I had the same question but I remember someone saying 'grapeseed oil'. But I like your baby oil idea too. Do Both! Re lens, since I don't have anything but a loupe, I like your mag'yg app too. Do it all, compare - do a video too :)
@@mfb6310 No problem bro I live in Finland its hard to find any kind of chemical because of the greenies, just basic things . I cant even find anyone who does gold plating. The camera app is free it can make the tiniest gem look supersized Ill give you a tip they guy with only a loupe but a passion and as your probably not a competitor where to find the best gems dirt cheap is Chanthaburi Thailand there's a lab there that's GIA trained, Ive also checked them out a couple gems with GIA and 100% right on but that's an expensive test Ill save you from. For the big rocks India is good but very risky a lot of conmen, but I have picked up a couple huge sapphires that made up for all the fakes, Investigating the sources will save you a lot of headaches, money and allegations of fraud. Some of my best rocks I got off Ebay 2nd tip look for positive reviews in German because they are the best,
@@tonylohi3685 Oh. Sorry, we've got many meddling Nannies, as well. Grapeseed oil is a cooking oil, though, that shouldn't be a bother! But if so, wow . And no, I'm def'y not a competitor. I was with the troops in AFG as a civilian, and visited the little haji shops at different camps. After a few years, I'm sure I have a colorful collection of likely mostly plastic or glass, but it's all in the journey, right? I had fun trying to look smart, though, looking through a loop and groaning appropriately. Every once in a while, I bring out the pile and try to learn what to do. I'm ready to just see if they'll melt. You sound like you have learned a lot too! And I like your tips. I worked with men from India - they tell me the businessmen are the biggest penny pinchers! Regarding 2nd tip - I love. I have forgotten most of my german, but I'm not surprised at your tip at all. Thank you so much, Greetings from Michigan.
