In this video, we distinguish between a 10.03 carat unheated blue sapphire with 7.93 carat heated blue sapphire under the microscope. Both have rutile silks inclusions which really helps in telling us if the sapphires have been heated or not.

That was a great video. Short, understandable, and to the point! Thank you. (10C's!! WOW- THAT WAS BEATIFUL!)

[@toby-7323]

Your videos are absolutely amazing. I learned so much about sapphires watching your channel. Using few lab equipments I can really understand how much should I quote the seller and how much should I quote to foreign buyers. Thank you very much for sharing this great content. Recently bought a lot of blue sapphire time to see which one are heated and which one are natural. I hope there is more than 1 natural once in the lot.

[@ThaiNativeGems]

Thanks a lot for the compliments and glad you found our videos useful. I will hopefully uploading some more soon, if time permits. Also, good to hear about your 'gem hunting' adventures. Best Regards, Tarun Gupta, GIA GG

Hi Sir Am from sri lanka Still am leaning abut gems Nice video Thank u sir

[@i.m.Q.2]

Dude! That one on the left is a dead ringer for one ive seen that was low thermal enhancenent. One small problem. The heating didnt take. 🙂 The image in your teaser? Dead ringer for my scope around 200x. Thank you!

[@ThaiNativeGems]

Might be, but the one in the left was GRS certified as unheated Sri Lankan. Thanks again for your inputs. Regards, Tarun Gupta, GIA GG

Thank you,,, pls about finger prints in heated and heated or treated ruby saphires🙏🏻

[@ThaiNativeGems]

When I do come across some of these stones, I will try to shoot some videos on this. I do also recommend to check other ruby videos we have made, which might have these type of inclusions under the microscope. Regards, Tarun Gupta, GIA GG

[@i.m.Q.2]

Have you ever scoped one of those out, and saw a finger print like inclusion? Years ago i bought this one sapphire for $1500 was it? Supposedly unheated. You ready for this? I scope it. You could see all the rutile broken up! You could see the iron in there as it was like cake mix peppered in. It looked like the finger print inclusions like berrylium treated stuff-but not quite. I never bothered with the oil immersion. I wish i could find the pics of it from my laptop or the other unheated one. Ironically its kinda like some of the old Ceylon (sri lanka material) but no zoning or windowing. Under the right halogen lights? You can see little specs of silver from the rutile. Its only a little 2.07 but ive got no regrets. Funky little off color like a corn flower? Discounted. The guy said heated. Scope says otherwise though yours is better than mine. 😊

[@ThaiNativeGems]

Everyone gemstone has there own characteristics and once we know what to look we can't forget it. :) Thanks again for your inputs. Regards, Tarun Gupta, GIA GG

[@i.m.Q.2]

@@ThaiNativeGems One thing I've learned over time, don't rely on certs. I'm not saying they're worthless, but it's amazing to see the obvious on some things and the cert says something different. That's why I don't put a lot of stock in a GIA cert. When the scope says flux, you get this lawyer/schizoid argument that says they can't say that. Then you hear from someone overseas that says they treat these stones with this copper and say it's natural-on a GIA cert each and evetytime.

[@meditationandnature2500]

Great information

[@muhammadamjidnoor3893]

The ink spot can even be seen with a naked eye at certain angles in a day light, depending upon the size of the stone as well. But, very informative and thoroughly explained.

[@ThaiNativeGems]

Thanks Muhammad in sharing your experience. Regards, Tarun Gupta, GIA GG

[@olegariocutin9317]

sir, do you recommend for the unheated blue sapphire for its texture, quality and price wise?

Good video just hard to hear your voice even with the volume turned up all the way. I think you were to far from the microphone. Thank you I still enjoyed it.

Sorry about that. It was video editing program which lowered the volume. Future videos won't have this issue. Thanks for watching. Regards, Tarun Gupta, GIA GG

How much tempreture required for emerald filling with resin

[@shanthgamage7]

The epoxy resin Opticon, a filler that has been used in Brazilian emeralds, is an example of an artificial resin. Fillers can be divided into four groups-soft (liquid) fillers, semi hard fillers, surface-hardened fillers, and hard fillers

[@sureshsahadev6116]

How much x loop is used to find out heated stones ? Pls advice

[@ThaiNativeGems]

If you do simple search on Amazon or other online sites, I am sure you get a reasonable priced gem-loupe. But, its not only about the gem-loupe but the practice in now how to see if the stone is heated or untreated. For average person, I do recommend to just send it to reliable third party certificate provider. I have actually written article about this which you can read here: www.buygemstone.info/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/ Regards, Tarun Gupta, GIA GG

Can you please mention the details about your Microscope ? Model ? The Magnification in which we can see the details you described in the video ?

[@ThaiNativeGems]

Thanks!

[@zubairge5349]

Bro which one is good heated or non heated???

[@ThaiNativeGems]

Unfortunately, not a simple answer. If you looking only based on treatments than non heated will sell in premium to heated as they are more rare. However, we have to also see five other factors like carat weight, color, clarity, cut grade, and sapphire origin to determine what is better or more premium sapphire. This is what I call 4Cs plus OT. Regards, Tarun Gupta, GIA GG

[@archiehillnaturalgemcompan9311]

A+++ very informative

[@anthonysalmon9965]

Thank you! 🔥

[@bigafghan_kabob2106]

What if it looks like the unheated but has blue cloud??

[@ThaiNativeGems]

Like any detective work we have to look at multiple clues to see if the stone has been subject to treatment or not. Blue cloud can be 'normal' color zoning or can be chemically diffused as well. If you see other clear unheated elements then most probably it is. Wish you the best of luck with your gemstone analysis. Best Regards, Tarun Gupta, GIA GG

With 10x or 14x eye glass can we get judgement?(about treatments)

[@ThaiNativeGems]

Hi Pravin, With practice, yes 10x or 14x eye-glass can assist in checking about treatments. The main thing is to see the indicators or clues. Regards, Tarun Gupta, GIA GG

[@shailoav5098]

Good Aren't both natural? 🤔😇😦 Y it heat? 🤔

[@ThaiNativeGems]

Yes both are natural, but one has been heat treated while other is not alter in anyway. The reason why gems are treated with heat as the natural color wasn't attractive and the heat treatment helps enhances it.

Thanks for the vid. I hit the like button. Can you show some breadcrumb looking inclusions in Africa ruby. I have one and cannot see rutilse needels in them. Trying to figure out if im buying good rubies or not. Thanks for your video. You can see some of the rubies I have bought on my channel. I only have on video... LOL

Hi Rock, I will see if I can find any rubies with breadcrumb inclusions. Are your rubies heated or unheated? Regards, Tarun Gupta, GIA GG

[@rockstomper8390]

@@ThaiNativeGems The guys out here in Afghanistan are saying they are unheated African rubies but I cannot find any 60 degree crossing needles in them. But the specific gravity seems to be correct and not heavy which you would expect with glass filled. I can find no bubbles.

[@MrBrucetom3752]

heated or unheated which one will be much more valuable?

[@shanthgamage7]

Now days heat treatment is a common practice to improve the clarity and enhance the color of Sapphire.a stone value doesn't depend on treatment. If a stone has right color luster ,Clarity which effectives for treatments.

[@shanthgamage7]

It's depond on colour , lustre and clarity of stone's. Just beacuse unheated stone doesn't have proper colour and beauty which doesn't value in the market .
