2) First Microscope - 3.03 carats Oval Ruby (min 4:19)
3) Second Microscope - 3.06 carats Cushion Ruby (min 5:24)
In this video, I tried to discuss the thought process we dealers look at in determining the value for a three-carat unheated Mozambique ruby based on 6 criteria's which I call 4Cs + OT. The criteria are Carat Weight, Color, Clarity, Cut, Origin and Treatments.
The video also provides microscopic videos & images of 'typical' natural inclusions you see inside unheated Mozambique rubies.
Hope everyone finds this information useful and wish everyone the best of luck with their ruby hunting!
For additional pictures and explanations regarding ruby treatments, I would recommend checking our very popular blog post: www.buygemston...

Noted! I will try to upload some more videos, whenever time permits. :)

Nice narrative. It's funny how the four Cs though as the importance order is color, clarity, cut, and carat.... but difficult because each of the four aspects count towards evaluation. However, Carat is usually last thing you look at. Color attracts interest in the potential, clarity refines interest in which exhibits are of most interest, and if already cut, then which of the cut shapes are the most valued, and which of those have the most carats, and least inclusions (that comes under the clarity part). In Thailand we value the Pidgeon Blood but in the West they prefer more the pinkish Mozambique and Madagascar ones. Also Burma are more pink and magenta, than the deep red seen in Thai Rubies, from the iron present in the bang ga cha mines (which are now of course depleted except for tiny pieces only fit for small ear studs). Nice display of inclusions and clouds in this video. I wonder why you do not mention or reveal the matter of the saw markings of the cut, if they are straight parallel, authentic, if curved parallel, then it is synthetic
Thanks for your insight and experience regarding rubies. Though in my experience, our Asian clientele actually prefers pinkish-red color, which is more common in Burmese rubies, while my western clients like the darker 'purplish-red,' which were depleted bang ka cha (Chanthaburi).
I can tell you have been in the trade for a long time as reminds me of the discussions I use to have with my Grandfather who came to Thailand in the late 1950s to buy rubies from there. It was definitely an experience just getting through the jungle that time. :)
Thanks for also pointing out that parallel lines mean authentic ruby while curved striae are synthetic.
I didn't point it out in this video as I did discuss synthetics in our past video - ua-cam.com/video/LHN-H96QCwk/v-deo.html.
Thanks again for your insights and Best Regards,

@@ThaiNativeGems thank you for your wonderful reply sir. Yes I would agree with you, but the local people in Thailand, who are of lesser knowledge and go more for the visual aspect and are not deeply involved in gemstone collection, meaning the common customer, who is just seeking a pretty gemstone, will prefer the pinkish. But that they old-school in Thailand prefer the dark red ones from Thailand simply because of the rarity and the fact that they are much more expensive in Thailand because you can't find them anymore. This is of course a result of the influence of marketing, which is done in every business around the world and every industry, to create a preference for the type of gemstones we can outsource the most. The dark red ones are reserved for high prices And our sold to the richer more knowledgeable collector who knows, that's some thing that cannot be mind anymore and we have seen the last of forever, is of course an essential rarity. This is why the dark pitch in blood red Thailand Ruby's are worth much more than the pink ones which will be coming from Burma, Madagascar, Zambia and a few other places like Cambodia aand are sold to the richer more knowledgeable collector who knows, that something that cannot be mined anymore and we have seen the last of forever, is of course an essential rarity. This is why the dark pigeon blood red Thailand Rubys are worth much more than the pink ones which will be coming from Burma, Madagascar, Zambia and a few other places like Cambodia and now Laos too. you have a much longer history of experience in this industry in Thailand than I have, whereas, most of my connections are in laos, well there is still a lot of potential minds to be discovered and a lot of mines in existence. to be honest I am using one of multiple UA-cam profiles I have to comment, because I did not want to comment using my gemstone related profile. That would be unethical to comment on your video as someone in the same industry. You seem to be a good honest trader and giving good knowledge in the English language about gemology from the perspective we have in Thailand. your website is very beautiful to compliments on that. You give good information about the gemstones, and you don't leave your customers in the dark. You teach them how to choose within their budget, and help them to understand the big differences in prices. Many people find it difficult to understand why to stones the same size can have such different prices. This video in particular explains that quite well. The 4 Cs as an evaluation method. But you still have to have that gut feeling and that special ability to notice something special in a gemstone. you can use the foresees as a basis, but it is the heart and soul inside you which speaks and says "this gemstone can be transformed into a very valuable gemstone"
@@ThaiNativeGems That is interesting to know that some of your Western clients prefer the dark "ruby red" color. This means they have also realized the rarity and higher value of Thai rubies that have depleted completely from the bang ga cha and other Thai mines, and will no longer be found anymore. I live in the south, but if I ever come to Bangkok when these bothersome lockdown stop, I would be honored to come and visit you And admire your gems and knowledge. We can exchange stories.
@@aonangthailandboattours4757 Thanks again for sharing your experience. Agree with you completely that prices of gemstones is strong 'gut' feelings which you can only gain from experience.
Also thank you for the compliments regarding my video and blogs. I am trying my best to share some of the knowledge I have gained over the years. But every day is of course a learning process. :)
@@ThaiNativeGems correct me if wrong...I thought pigeon blood is mostly pure red with a secondary orange...instead of pinkish or purplish ???
thq for share us the knowledge about this ruby stone ,,i hope u always share other stone ,,like zultanite ?alexandrite ,,thq
Today, if we look back the price $ 27000 , is too low , and also top quality Ruby stone over 3 ct , 'become hard to get " .
So true. Never have guess that COVID lockdowns would have caused ruby prices to super-charge higher. Wish I bought some just for an 'investment.'
Thanks for your inputs.

Your videos are very informative but the audio quality is so low. It sounds like you as you speak, you drift away from the microphone then you get closer to it. I would really enjoy the videos more if the audio was a) consistent volume, b) louder overall. My hearing has been checked, btw and I still have to tell others nearby to be quiet, even if my laptop volume and player volumes are both up. Thanks also for showing an example where double white 'feather' like inclusions parallel to each other are a sign of genuine stone. I've read many different sources that say parallel whisps of white are signs of lab-grown. I was confused until now. Side note: Do similar white parallel inclusions also form in red spinel or only ruby? Thanks.
Thanks for your comments and sorry for the audio quality. I try my best to keep it consistent and to make it as loud as possible. Hopefully, we can rectify this issue in our future videos.
Regarding red spinels, the most common natural inclusions look like 'fingerprints.' Not sure about white parallel inclusions. I will try to get some nice red spinels to take some videos of it so can share it on the channel.

Please could do a video on microscope on papraracha Sri lankan gem stone thanks
Hi sir... I would like to ask you i have a 7 carat ruby pigeon blood. But i can see my ruby has a crack inside it. Can a crack be repaired in stone?
The "Cut" may not be as significant a factor in the valuation of a Ruby (or anything else) but it does affect the value. While these are both beautiful stones, they are poorly cut and polished.
They look to me to be polished to 14k grit diamond at most and the Pavilion Facets are not good on the Oval especially. They lack symmetry. I don't know what grade you might give these cuts but I'd say both would be in the Medium Range for Cut quality. Maybe a bit better for the Cushion except for the pits/craters at the surface.
Thanks for sharing your experience. I do agree the cut grade for especially the three big gemstones rubies, sapphires or emeralds do suffer generally and these stones are not 'ideally' cut.
There always a trade-off regarding carat weight, inclusion location plus retaining the color as much as possible and therefore makes color stones more susceptible for having lower or 'unsymmetrical' cut grades.
Anyways thanks for your opinion regarding this.

Very informative video ,, thanks for shearing sir👍
Thanks!
Cool. I found some gemstones but not sure what they are
Best way to check is by sending to reliable third party certificate provider. They can verify and check what type of gemstone you have.

Hi do natural rubies have horizontal line in them,,,,,which looks like layer or cracking type,,,,plz reply,,,,,wearing natural ruby with horizontal lines good or bad plz reply me
Hi,
The only way for me to check is to see actual ruby in person. Generally if lines of rubies are not curved, but straight (color zoning crystal) then yes it is natural ruby. But I am not sure layer or cracking type means? Is it an fracture inclusion? This people can make manually so doesn't guarantee that is natural or synthetic ruby.

Thank you for this. How much would a 3.45/ 3.5 carat unheated pigeon blood Burmese Ruby with some inclusions cost please? Thank you
Finding one Burmese of this quality is exceptionally difficult, plus being unheated. Generally there are now priced over $100K per carat higher or more.
If you have a budget for such a stone do let me know. :)

Tarun Gupta, GIA GG
Thanks 👍 a lot. Best regards😊. Keep teaching!

Can I get the price guide the color wise
Good video
Halo mat siang ijin pak saya punya rubi bagaimana cara tes mantannya.
excellent video, thanks. Were the rubies $27k each?
Hi Brom, yes US$27,000 each. Thanks for compliment. Hope you found information useful.
Details of one of them can be seen on e-commerce site. Link provided here: www.thainativegems.com/product/3-03-carats-grs-certified-vivid-red-pigeon-blood-unheated-untreated-mozambique-ruby/
@@ThaiNativeGems tyvm 4 the reply. Honestly, this is the best ruby explanatory video I've seen.
Thanks for the info, the only mistake in the program is choosing a blurry background that doesn't give the viewer a chance to see clearly what's inside the stone .
Thanks for suggestion. Will take that into account for my next videos.

Why does your natural unheated ruby showed gas bubbles?
There aren't any gas bubbles. Maybe what you looking at is natural transparent crystals.

Hi Guptaji, how to find the origin without knowing. eg I got Kashmir Sapphire 16.16 carat but unable to put on Christie for auction as there is lobby that decides the origin, so quite gloomed.
Hi Pawan-ji,
Unfortunately, the only way to check the origin is by 'going' through reputable labs like Gubelin, GIA or GRS. For more details of global reputable labs you can read it here in our blog post: www.buygemstone.info/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/
If you don't get them to certify it as 'Kashmir' then unfortunately there is no way for Christies accept and auction it. It is their way to make sure your claim is valid. Sorry but this 'is the lobby' system we currently have.

Tarun Gupta, GIA GG
please make videos on diamond cvd and hpht and hpht treated filling coloure treatment
Thanks for suggestion. If time permits, I will try to make a video regarding this - natural diamond, their treatments, and lab grown diamonds (hpht and CVD). Though checking these in microscope is not very helpful as most of these stone are clean.
Generally, you do need to send these stones to sophisticated labs to check.

Can I ask what is the price for Mozambique unheated pigeon blood clarity SI2 - I1 , under 1 crt ..
Hi Cloversense,
Is the clarity based on inclusions in the stone or crystal transparency (transparent, translucent or opaque). This will affect the value of the ruby.
For more information, you can check this blog post: www.buygemstone.info/how-much-does-a-one-carat-ruby-cost-video/
Also, the above link provides in detail how much it should cost around 1 carat, so slightly below 1 carat should be a similar range.
Best Regards,
Tarun Gupta, GIA GG
@@ThaiNativeGems translucent with big chalcopyrite , but its okay .. I get the idea , thank you 😄
How much would a 10ct ruby unheated be worth? I just inherited it I'm just curious a ball park figure?
We have see the four other factors as well (in total there are 6 factors) to help determine what the price can be. Currently the factor you have provided is Carat weight and Treatment. Other factors includes Color Range, Origin, Clarity and Cut Grade.
Best Regards,
Tarun Gupta, GIA GG
And good videos
Microscope type?
Really old, which I bought around 16 years back. I'm sure they don't sell this one anymore.
You just need any good quality - Gem Testing Gemology LED Darkfield Microscope.
Wish you the best of luck with gemology journey.

شكرا لك هل الفقاعات طبيعية ام صناعية
Hi, if the stone has 'gas bubbles' then it is either synthetic, glass lead, or sometimes natural flux-treated rubies.
Natural unheated or normal heated rubies don't have any gas bubbles but only natural crystal inclusions. Sometimes natural inclusions can look like bubbles but in end the are angular and gas bubbles are round-looking so they are not the same.
Anyways I do recommend seeing this synthetic video which we made earlier to see how gas bubbles look like (link: ua-cam.com/video/LHN-H96QCwk/v-deo.html) and compare with the inclusions you see in this video.
Hope you can see the difference.
Best Regards,
Tarun Gupta, GIA GG
Do you sell them?
Yes, all these rubies are already sold.
@@ThaiNativeGems how much does a 9 carat Mozambique ruby unteated, unheated gemstone cost ??
I am from myanmar I get a lot of knowledge from you.If I find perfect one,I will contect u
Wish you the best of luck for ruby hunting. It can be both daunting and exciting as well.

Ok
Too pink for real pigeon blood. It has to have a touch of orange-peach to be pigeon blood. Definitely no pink. However, these are absolutely beautiful and worthy of their price
I personally agree with you and this is an issue with all 'reputable' labs being a little too generous about 'pigeon-blood' color. Color definition is still a big issue in all the major labs.
Do you have any recommendations and how we should go about tackling this issue?

Thankyou for very informative video but your volume is very very low always.
Really? I will double-check. But, on both my computer and mobile device the volume is actually quite loud.
@@ThaiNativeGems I have a Samsung S9 and beleive me you need to increase volume.
@@eddies8174 Noted... I will definitely increase the volume in my next video. Thanks for letting me know. Hope all is well!
The volume was OK on my device
@@ThaiNativeGems if you use an iPhone I very much recommend an app called voice recorder pro, or just do voice overs in iMovie on the phone. Make the video first, and then add a voiceover with the iPhone in iMovie will be very loud and clear. Or if you are using a computer or Mac, I would recommend to invest in a blue yeti studio microphone about 10,000 baht. i use couce recorder pro on iphone, because it has high quality sound and can add equalizer and decibel boost/reduce to make the sound audible. Otherwise, on the computer I use the blue yeti USB external microphone. It was well worth the investment
