Unheated Sapphire VS Heated Sapphire

[@slwtgf]

Finally- this answers many questions and visually, not only verbal explanation! Thank you!

[@lroberts9094]

This video came up during some research on identifying unheated vs heated gemstones. One author described observing what he termed "melted" schiller lines in heated gems. To this end, I did see lines that were straight and parallel in the unheated gems, while similar lines seemed to form random curves and branches in the heated gems. The second sample showed a number of instances of "halos" appearing around inclusions. I have no idea if these are the differences we should be identifying. But I could definitely see a difference between the heated and unheated gems. Thanks for the video!

[@francescoprotopapas5482]

I will make a new one soon. ;-)

[@donnajohnson3792]

I wish there was sound and an explanation comparing the unheated v. the heated. I still don't know what to look for since both looked the same.

[@HamZa-ew1mr]

non heat saphire have some areas blue and some areas white but heated one has same blue colour in all the areas of stone 🤗

[@yv1497]

unheated has a finer lines unconnected where heated would enlarge those and connects them together unheated has angular gas bubble, nearly to none where heated has a lot more gas bubbles and are mostly round

[@saubhagyaratnamshrishreyaj667]

Terrific, awesome. Too much educational. No words enough to thank you

[@siriwatjiamanusorn552]

This is a very instructive presentation ever seen. I appreciate so much.

[@slwtgf]

Ya took the words right out of my head! Funny how lengthy, overly detailed presentations go in one ear, and out the other, but this one achieves understanding in a short + sweet fashion!

[@bhavyasoni7671]

Thanks a lot. Very good for understand difference between natural and heated. It will more useful if you explain from which origin it is and why? Thanks🙏

[@eddieharris6004]

Would have been nice to see the same stone before and after heat treatment.

[@sihalagemzone]

This will be the best if it has explanations. Thanks.

[@mengistuch2]

Very informative video. Thank you !

[@m0dg0d16]

One quick question: Does hardness change if sapphire goes through heat treatment?

[@MinhMikeNguyen]

Very good and educational video. May I ask what microscope system (and specs) you are using? Crispy clear image!

[@francescoprotopapas5482]

Hello, I use a amscope gemological microscope and a Canon EOS 500D reflex camera

[@eventssrilanka9410]

THANKS FOR YOUR VIDEO

[@fgmace]

This is very much appreciated!! Do you have one comparing heated unheated rubies?

[@francescoprotopapas5482]

Hello, In this moment I haven't much time, but I'll try to do the same kind of video with rubies.

[@fgmace]

The critics here are interesting. I don't know why anyone would watch this if their intention was other than to learn to identify unheated from heated. Yeah, people complaining about what's NOT included (oh, a pun!) are ... well ... I'll stick with 'interesting' ... I'm still watching and pausing and backing up and pausing ... it is SO very instructive ... full screen on my Macbook Pro and my own microscope and sapphires to compare is nice too ... but, yeah, thanks again!!!!!!!!

[@IndusRiverRock]

Amazing very beautiful 👍

[@royalsingh]

Thanks for uploading it.

[@4everscorpiolove]

😴 The heat-treated stones are boring compared to the one that's untreated. Still pretty though.

[@tjrank1]

For some reason I have my sound volume turned up but there is no sound. Is there any sound in this instructional video???

[@Trabovski]

I had mine fully turned down in case if there is any sound, didn know there wasnt any

[@zainulhassan7092]

Whats the magnification power of that Microscope? Is it 50x?

[@francescoprotopapas5482]

Hi, In this video I reach the 60x magnification

[@greenfootprint2680]

Do you think X45 would be sufficient enough to capture what you’ve shown here also?

[@idonthaveaname42]

Where did u get your microscope

Great video. I was hoping to see a uraninite inclusion I came across one that quite confused me recently.

[@danconstanciojr8476]

Can you say that Heliador is a Sapphire? If you don’t mind, “ What microscope are you using?” Thanks…. By the way, this is a spectacular video. Just wonderfulSci.

[@KenWangpiano]

Heliador is a beryl, so it's in the emerald family as opposed to the corundom/sapphire group

great job

@@francescoprotopapas5482 sir I also have a trinacular stereo microscope, will I be able to take detailed inclusion pic like you have done in ur video, is that possible in my microscope

[@francescoprotopapas5482]

@@placeswithabs With an adapter for the third eye of the microscope I think that you'll haven't any problem to capture nice pics.

[@placeswithabs]

@@francescoprotopapas5482 do you recommend the c mount adapter from amscope is a good idea, because I tried with a canon 1500D I couldn't take a proper zooming, that's why I asked your help.

[@nevaehb.4371]

Wow, impressive video.

[@Kabr-tv7ii]

hi, is the gem tester metres tells you about blue sapphire is fake or not ?

[@francescoprotopapas5482]

Hi, I'm sorry, but a "normal" cheap gem tester cannot tell you if the stone it's natural or not.

[@obaidrahman8181]

amazing ... should be appreciated (y)

[@chewminem2044]

These two gems have so many inclusions... is it common to every sapphire? Mine don’t seem like it from far away.

[@francescoprotopapas5482]

Hello, I used some very included gemstones to show many different interesting inclusions that you can find inside sapphires. Usually sapphires have some inclusions, but sometimes you can find no inclusions or tiny ones. I hope that my video can help you in some identifications.

[@chewminem2044]

Francesco Protopapas thanks for the clarification. Looking forward to cutting my other one purple with blue. Can I send you an email with video if you can tell me if it’s amethyst or purple sapphire? And possible worth

[@francescoprotopapas5482]

@@chewminem2044 Hi, Try to check the refractive index of the gemstone

[@buggsy5]

@@francescoprotopapas5482 A refractometer is probably the best - and a useful one is not expensive. Another method is by using one or more calibrated refraction fluids. The crystal shape might be instructive. A bit more risky would be a scratch test. A steel knife will scratch amethyst, but not sapphire.

[@alexnikoo244]

I think the niddle like inclusion speak about unheated sapphire

What lens power you use 10 x or more

[@francescoprotopapas5482]

Hi, From 10 to 60 X

[@shanthawimaladharma5295]

Oh, for goodness sake. This video needs audio. Please, someone talk about sapphires or take this video down.

Is it the same stone or not ?

Hello, In the video there are 3 different stones, the first one is an unheated sapphire, and the other ones are heated.

Before and after images. An explanation would have went a long way to educate us. So lacking.

[@navalshastri]

Is it the same gem you are showing in heated unheated?

[@francescoprotopapas5482]

Hi, thank you for your comment. This is the video Unheated VS Heated, but I use different stones for every video

[@petep7]

This is the perfect example of how NOT to do an instructional or educational video. Try explaining to those you are trying to teach what they are looking at and for. A bunch of inclusions that ma or may not be heated look very similar to the uninitiated and inexperienced.

[@francescoprotopapas5482]

Hello, This video it's only a support to my students, and I explain the video in the gemological training course. I have uploaded in you tube the videos to have it in case of problems with the pendrive.

[@altar7885]

Where is it said that it is an instructional or educational video?

[@lordcromwell5512]

fake

[@ishika82721]

Disgusting

[@CoinOppLtd]

audio would be nice!! wtf am i even looking at??? a little narration as to what the hell im looking at would also be great. You do know you can set your video so only people you give a link to can view it. so if what you say is true about this being for your class...set the fucking thing to private. no need for such a poor video out for the world to look at it.
