Brother i have a ruby ,it looks like glass mean transparent i can see thing on the other side through it but in red color. Is it real buy or not my ruby is so transparent.
If you see no visible inclusions it's probably synthetic. Very rare to find a real ruby that's entirely or almost entirely free of inclusions. Watch some of his other videos on rubys and you'll know what to look for. Also if someone is pressuring you to buy quickly that's a red flag that it could well be fake. Take your time to learn so you don't make big mistake and lose money.
Thanks Jessie for sharing this and I do agree with it completely. Never get pressurize for purchase and do you homework about gemstones. Another way to be safe is send the ruby (or stone) to reliable 'third party certificate provider' which we wrote a blog post about - www.buygemstone.info/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/ and verify if it is actually a ruby and if it has subject to any treatment.

Where do I get lab-created emerald and rubies that are good quality, no fracture filling and heat treatment? Biron / Ramaura/ Chattam? And which is the best method for rubbies and which for emeralds? flux fussion / pulled Czochasky / hydrothermal ?

Thanks, great video. The Mozambique Rubies, what should I look for on a Polariscope when putting them on one? Hope you can help - so too the Blue Sapphires.
I have a ruby, but I’m not sure if it’s a real,genuine one. I tried to cut the mirror with it and it cut the surface of the mirror,it’s very clear you can see through it and it’s red blood color and feel very heavy in your hand,are all these characteristics,proven it’s a genuine and natural ruby? Thanks
Hi, The best way to check if the ruby you have is genuine or not is by submitting it reliable third-party laboratory (blog post on this: www.buygemstone.info/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/) or showing to an experienced gemologist. Your test just proves the substance you have is harder than glass Mohs scale 5.5 to 7, which is a good sign. Weight test (or Specific Gravity test) is very sensitive and cannot be done by feeling it on your hand and need to measure accurately. Best Regards, Tarun Gupta, GIA GG
great video simple and straight to the point just one question whats the difference between a heated and unheated ruby (natural heat) does it effect the color of the ruby or does it make it less valuable??
Hi Roham, Great explaination was provided by blue copper above. In summary, rubies are treated because in their natural state they weren't as "attractive." Treatment makes them more saleable. But because treatment rubies are less rare they are less valuable than untreated rubies. Thanks for the question. Will be uploading a video in how much 1 carat ruby cost soon which will explain this. Regards, Tarun Gupta, GIA GG
If you see gas bubbles (and NOT mistaken with natural inclusions) then you will either have a synthetic ruby or 'glass-lead' treated ruby. Regards, Tarun Gupta, GIA GG
Hi TNG, i have an composite corundum or cobalt doped composite sapphire, it's mean totally synthetic sapphire or 100% imitation sapphire or natural mix a lead glass/silica? Thanks
Composite generally means mix with some outside substance including 'mixed lead glass/silica.' So, its natural stone but aggressively treated with outside material. This makes it drop in value dramatically. Best Regards, Tarun Gupta, GIA GG
Depends on other 3Cs + OT criteria (Color, Clarity, Cut Grade, Origin and Treatment). Carat weight is just one criteria we consider when looking at pricing. Regards, Tarun Gupta, GIA GG
Can a Ruby show orange hue inside in when light is passed through it?? I have a gem,it's dark red,and confused between garnet or Ruby, it's emitting little blueish,pink and orange from some angles,it's have so many line like inclusions.
Yes, ruby cans show an orange hue inside, especially Mozambique origins. The only way to determine if the stone you have is garnet or ruby is to check the refractive index and if the stone is single refractive (which garnets or spinels are) or double refractive, which rubies or other corundum gemstones are. A third-party lab can check this quite quickly. Best Regards, Tarun Gupta, GIA Graduate Gemologist

Does this apply to semp precious stones like garnet? Do the synthetics made of 100% glass also always have bubbles, the surface fracture and the clarity?
Hi, Every gemstone have different properties so it is difficult to generalize if same rules applies in other semi-precious gemstones. For example, natural tourmaline they have liquid filled inclusions which look similar to gas bubbles.

I would like additional information . Gems mining most of the ruby fracture needs to be filled with glass or other compounds to facilitate grinding. Glass that can be filled with ruby divided according to chemical composition, there are several types as follows: 1. Soda-lime glass 2. Borosilicate glass 3. Lead glass or crystal glass This type of glass has more than 24% lead oxide and has a high refractive index. 4. Opal glass 5. Aluminosilicate glass 6.Alkaline-Earth Alumino silicate 7. Glass-Ceramics 8. Crown glass 9. Flint glass 10. Bismuth glass Because lead glass has good optical properties but is not durable and can dissolve in water, acids, and alkalis when used for a long time. Therefore, choose to buy gemstones that do not contain lead oxide , bismuth oxide and silica . Other types of glass the quality of gems will be different, such as bismuth glass. However, when purchasing gemstones, you should choose and be inspected with an X-ray Fluorescence (XRF) tool only because it can determine the amount of lead in percent. To consider the appropriate purchase price.
Thank you for your insight regarding this. It looks like you are quite knowledgeable regarding the different substances used to fill inside glass-filled rubies. But I guess my question will be if the labs classified all above as 'glass-filled rubies or composite rubies?' Also, I believe currently they don't identify to us what type of glass is filled in the ruby even though they do have test with 'X-ray Fluorescence (XRF) tool.' Thanks & Best Regards, Tarun Gupta, GIA GG
Hello sir... I have a ruby gem and I already brought it to gemologist and he said that my ruby is synthetic but, my ruby is 9mohs, 9.36 carat, it has healed cracked clearly can see. But I don't really can't understand somehow the gemologist made me doubt by his decision. As I understand there's no cracked in synthetic ruby, he told me my ruby is synthetic lab grown ruby. Because I tot lab grown ruby is not a synthetic it's also a real ruby correct me if I'm wrong. And I seen too my ruby under his 200x microscope. I saw a very tiny bubble and he said it's is a fake but it is very hard to see without the microscope. What do u think sir? The gemologist firstly didn't sure whether my ruby a high valuable or fake, but after that he decided to say it's fake. My ruby has actually a healed long cracked and a very tiny bubbles.
Hi, Having cracks in stone doesn't discount it in being natural or not. Also, synthetics and natural rubies have exact same properties - the only difference is one is made in the lab and other is naturally mined. Good examples of 'included' synthetic stones can be seen in our TH-cam channel we have made regarding synthetics rubies: th-cam.com/video/LHN-H96QCwk/w-d-xo.htmlsi=wjQPXghPTVXJA4OZ - which all of synthetics were intentionally 'included' to trick the end consumer. So, the only way to see if natural or synthetic is by checking for signs (like a detective) and if the gemologist did check your stone and thinks is synthetic he must have saw some indications to make that conclusion. Anyways, thanks for your comment and good luck with your stone. Regards, Tarun Gupta, GIA GG
I bought a gorgeous ruby ring. It would have cost me thousands of dollars had they not been glass filled. It was in a gold over silver casting. The jeweler said they are not real because she noticed they were in a gold over silver casting. It really pissed me off because she was acting like an expert but I am also a graduate gemologist. I told her they were glass filled rubies. They are absolutely gorgeous, and I could never afford them had they not been glass filled. Not all jewelers are gemologists, so keep that in mind when they share there "expert" opinion with you. Always ask for their credentials.
Agree with you point completely "Not all jewelers are gemologist" and to guarantee what you getting is "genuine" either ask for credentials or get reliable third party certificate. Regards, Tarun Gupta, Graduate Gemologist (GIA)
Mine is 100% crystal clear but red no bubbles no cracks I can see right through and it’s like 5ct but I can’t believe that it’s real and all the tests I do it passes if it is real it’s nice and unheated as the guy said it was but seems too perfect like glass
Recommend getting certified by reliable Third Party certificate provider. Details regarding different certificate providers you can read through our blog post - buygemstone.info/2017/03/10/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/. With a certificate you can guarantee if the stone you have is natural ruby or not. Regards, Tarun Gupta, Graduate Gemologist (GIA)
Gem tester can assist in telling your if particular stone has 'chemical' property of a ruby (or corundum family). However, it won't be able to tell difference between unheated, heated, or synthetic ruby as they all have same chemical composition.

26k or whatever prices that’s ur asking price .. not necessary a market price ... where u can find the unheated rubies with less price that you have mentioned ! Wether it’s from mogok Mozambique Madagascar tajik , Afghan rubies
Felista Gems - Thanks for your comment. Of course, there are more cheaper unheated rubies but they also more expensive ones. Market price is never fixed and is dependant on supply, demand and the quality of particular gemstone (4Cs plus origin or treatment). Buying gemstones is both art and skill. Just for your information the 26K stone is already sold.
The cut didn't seem that nice plus that big inclusion that's crazy it sold for that, good for you. I just got a really dark blue untreated sapphire for free. I think it's similar in grading as ruby, the same observations still apply in grading sapphires.
Technically cgi has a a whole section of the current market rate on rubies. The seller is absolutely right. If you’re in this business long enough you know that stone has a market value of 17k to 29k$. Just for your information:) @tipsstrips7002
Both are 'real' but the one in the left is highly treated with 'glass-lead' while the right is 100% natural, unheated & untreated. Regards, Tarun Gupta, GIA GG
Hi Johnny, yes you can email the images at sales@thainativegems.com and I can take a look and let you know my thoughts. Of course, I cannot guarantee through pictures regarding the treatment as it really depends on the quality & accuracy of the image.
I am confident a stone could be made with none of the characteristics you pointed out in the lead glass filled ruby. The only real difference between the two would be that one requires slave labor and blood shed to find, and the other does not.
Actually the process in mining both quality is the same. And both is NOT slave by labor or blood as it is mined from UK listed company and therefore have to be accountable to governments and investors.
Yes, usually they do cost around US$3 per carat. But the cost really also depends on quality of glass-filled ruby and how clean they look. So, they are different grades for these type of stones as well. Regards, Tarun Gupta, Graduate Gemologist (GIA)
Hi lellouche rene, We actually do have a video that explains about all ruby treatments plus the other 4Cs (carat weight, color, clarity and cut grade) and origin as well. Provided the link here: th-cam.com/video/ornjTJv9pl8/w-d-xo.html If you want to avoid to hear all technical stuff in beginning of the video you can look at time stamps in video explanation below and click on microscope videos for heated ruby example. Regards, Tarun Gupta, GIA GG
Good information regarding glass filled stones. I doubt synthetics have even remotely similar presentation of bubble artifacts, though. but, ... 26,000 dollars, ..., good thing your video was a little blurry, because those meets are atrocious pay me 5 grand, and I'll cut it into a $30,000 stone.
+fdsafdsafdsa Flame fusion rubies you can see gas bubbles, but as you stated it won't be 'as clear' The 3 carat (26k) stone as been sold. Though I might take up your offer for the next expensive stone I have on hand.
Sorry the microscope videos aren't very clear. The white spots in natural ruby is most probably dust or dirt on surface which is not the same has internal gas bubbles. Thanks for your feedback. Best Regards, Tarun Gupta, GIA GG

I would like additional information . Gems mining most of the ruby fracture needs to be filled with glass or other compounds to facilitate grinding.
Glass that can be filled with ruby divided according to chemical composition, there are several types as follows:
1. Soda-lime glass
2. Borosilicate glass
3. Lead glass or crystal glass This type of glass has more than 24% lead oxide and has a high refractive index.
4. Opal glass
5. Aluminosilicate glass
6.Alkaline-Earth Alumino silicate
7. Glass-Ceramics
8. Crown glass
9. Flint glass
10. Bismuth glass
Because lead glass has good optical properties but is not durable and can dissolve in water, acids, and alkalis when used for a long time. Therefore, choose to buy gemstones that do not contain lead oxide , bismuth oxide and silica . Other types of glass the quality of gems will be different, such as bismuth glass. However, when purchasing gemstones, you should choose and be inspected with an X-ray Fluorescence (XRF) tool only because it can determine the amount of lead in percent. To consider the appropriate purchase price.
Thank you for your insight regarding this. It looks like you are quite knowledgeable regarding the different substances used to fill inside glass-filled rubies.
But I guess my question will be if the labs classified all above as 'glass-filled rubies or composite rubies?' Also, I believe currently they don't identify to us what type of glass is filled in the ruby even though they do have test with 'X-ray Fluorescence (XRF) tool.'
Thanks & Best Regards,

Thank You for these videos
Hello sir... I have a ruby gem and I already brought it to gemologist and he said that my ruby is synthetic but, my ruby is 9mohs, 9.36 carat, it has healed cracked clearly can see. But I don't really can't understand somehow the gemologist made me doubt by his decision. As I understand there's no cracked in synthetic ruby, he told me my ruby is synthetic lab grown ruby. Because I tot lab grown ruby is not a synthetic it's also a real ruby correct me if I'm wrong. And I seen too my ruby under his 200x microscope. I saw a very tiny bubble and he said it's is a fake but it is very hard to see without the microscope. What do u think sir? The gemologist firstly didn't sure whether my ruby a high valuable or fake, but after that he decided to say it's fake. My ruby has actually a healed long cracked and a very tiny bubbles.
Hi,
Having cracks in stone doesn't discount it in being natural or not. Also, synthetics and natural rubies have exact same properties - the only difference is one is made in the lab and other is naturally mined.
Good examples of 'included' synthetic stones can be seen in our TH-cam channel we have made regarding synthetics rubies: th-cam.com/video/LHN-H96QCwk/w-d-xo.htmlsi=wjQPXghPTVXJA4OZ - which all of synthetics were intentionally 'included' to trick the end consumer.
So, the only way to see if natural or synthetic is by checking for signs (like a detective) and if the gemologist did check your stone and thinks is synthetic he must have saw some indications to make that conclusion.
Anyways, thanks for your comment and good luck with your stone.

Nice video
Thanks
Thank a lot. Keep up the good work .
My grandma gave me a ruby ring a few years ago
I bought a gorgeous ruby ring. It would have cost me thousands of dollars had they not been glass filled. It was in a gold over silver casting. The jeweler said they are not real because she noticed they were in a gold over silver casting. It really pissed me off because she was acting like an expert but I am also a graduate gemologist. I told her they were glass filled rubies. They are absolutely gorgeous, and I could never afford them had they not been glass filled. Not all jewelers are gemologists, so keep that in mind when they share there "expert" opinion with you. Always ask for their credentials.
Agree with you point completely "Not all jewelers are gemologist" and to guarantee what you getting is "genuine" either ask for credentials or get reliable third party certificate.

Mine is 100% crystal clear but red no bubbles no cracks I can see right through and it’s like 5ct but I can’t believe that it’s real and all the tests I do it passes if it is real it’s nice and unheated as the guy said it was but seems too perfect like glass
Recommend getting certified by reliable Third Party certificate provider. Details regarding different certificate providers you can read through our blog post - buygemstone.info/2017/03/10/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/. With a certificate you can guarantee if the stone you have is natural ruby or not.

Is gem tester tells you pure Ruby ?
Gem tester can assist in telling your if particular stone has 'chemical' property of a ruby (or corundum family). However, it won't be able to tell difference between unheated, heated, or synthetic ruby as they all have same chemical composition.
Amazing video thank you
Glad you enjoyed it
Hello thai thai, great video but no audio. Thats a damn shame. Do you make it to Tucson Arizona gem and mineral show in the winter? I live just east of tucson in Pantano AZ. yes the ghost town. would like to hook up with you if so. Please respond.
RICK in Pantano Arizona U.S.A.
Happy trails.
Hi Rick, sorry regarding the audio, it is actually there but really really 'low volume.' Will have to make sure it is a lot better for the next video. Regarding visiting the Tucson gem show, we actually don't go anymore. Though if you want to contact us please feel free to email me at sales@thainativegems.com, anytime!

GOOD VIDEO
PEOPLE are MINIONS !!!!!!!!!!!!!
Thanks. Why do you believe people are minions?
26k or whatever prices that’s ur asking price .. not necessary a market price ... where u can find the unheated rubies with less price that you have mentioned ! Wether it’s from mogok Mozambique Madagascar tajik , Afghan rubies
Felista Gems - Thanks for your comment. Of course, there are more cheaper unheated rubies but they also more expensive ones. Market price is never fixed and is dependant on supply, demand and the quality of particular gemstone (4Cs plus origin or treatment). Buying gemstones is both art and skill. Just for your information the 26K stone is already sold.
The cut didn't seem that nice plus that big inclusion that's crazy it sold for that, good for you. I just got a really dark blue untreated sapphire for free. I think it's similar in grading as ruby, the same observations still apply in grading sapphires.
toolofbordem pls help me how to get pure gem stones
I have top antic gem con Num-wa.me/918279290151
Technically cgi has a a whole section of the current market rate on rubies. The seller is absolutely right. If you’re in this business long enough you know that stone has a market value of 17k to 29k$.
Just for your information:) @tipsstrips7002
thank you
Helpful video
Fake left real right?
Both are 'real' but the one in the left is highly treated with 'glass-lead' while the right is 100% natural, unheated & untreated.

Unheated and Untreated are good for Astrological purpose
Sound very low
Apologies, it was one of our earlier video and did upload the volume really low.

I have one that I believe is real is there anyway I can email you a picture up close and you give me your thoughts
Hi Johnny, yes you can email the images at sales@thainativegems.com and I can take a look and let you know my thoughts. Of course, I cannot guarantee through pictures regarding the treatment as it really depends on the quality & accuracy of the image.
Amazing..thanks..love from Pakistan 🇵🇰
I have a tanes of rubies rough
Call me
Wow 🤩
I am confident a stone could be made with none of the characteristics you pointed out in the lead glass filled ruby. The only real difference between the two would be that one requires slave labor and blood shed to find, and the other does not.
Actually the process in mining both quality is the same. And both is NOT slave by labor or blood as it is mined from UK listed company and therefore have to be accountable to governments and investors.
I want a blood ruby 🙃😢
Lead heated rubies now cost $3 per carat. I guess there's too many of them.
Yes, usually they do cost around US$3 per carat. But the cost really also depends on quality of glass-filled ruby and how clean they look. So, they are different grades for these type of stones as well.

Wow
You had to tell us the difference beetween heated and unheated I think...
Hi lellouche rene,
We actually do have a video that explains about all ruby treatments plus the other 4Cs (carat weight, color, clarity and cut grade) and origin as well.
Provided the link here: th-cam.com/video/ornjTJv9pl8/w-d-xo.html
If you want to avoid to hear all technical stuff in beginning of the video you can look at time stamps in video explanation below and click on microscope videos for heated ruby example.

Everything is fine but with very low volume
Sorry about the low volume. I realized it only after uploading the video. Hope you found the information in video useful.
Indeed, the information was very useful... Good luck for the future👍

no difference between them at all.
Tourmaline paraiba
Good information regarding glass filled stones. I doubt synthetics have even remotely similar presentation of bubble artifacts, though.
but, ... 26,000 dollars, ..., good thing your video was a little blurry, because those meets are atrocious
pay me 5 grand, and I'll cut it into a $30,000 stone.
+fdsafdsafdsa Flame fusion rubies you can see gas bubbles, but as you stated it won't be 'as clear'
The 3 carat (26k) stone as been sold. Though I might take up your offer for the next expensive stone I have on hand.
The real ruby have white dots also 😂
Sorry the microscope videos aren't very clear. The white spots in natural ruby is most probably dust or dirt on surface which is not the same has internal gas bubbles.
Thanks for your feedback.

@@ThaiNativeGems is there is any email i can share photo of blue sapphire taken with micro camera to advise if its cobalt glass filled or no
What you talking about?
