In this video, I tried to discuss the thought process in determining the value for a blue sapphire based on 6 criteria's which I call 4Cs + OT. The criteria are Carat Weight, Color, Clarity, Cut, Origin and Treatments.
For additional pictures and explanation regarding blue sapphire treatments I would recommend to check our very popular blog post: buygemstone.info/2013/11/07/b...

So cool!
Thank you for all your very helpful videos. They are so interesting! Would it be possible to request a similar video about how you like to determine the value of a Padparadscha sapphire? Many thanks 🌸
Thanks for your suggestion. Once I do come across a few Padparadscha, I will make an updated video.

Great video! Thank you! Saved me $8000!
Glad it helped!
Good info great video, thanks for making the video.
Hello love your content was wondering if you could tell me about these gems I found behind a book shelf in our new house
Recommend getting them checked from a reliable third-party lab or from experienced gemologist.

Hello, u talked about origins.
Maybe can you share more on what are the likely origins of sapphires arnd the world and how is it valued?
Hi, yes planning to make one comprehensive video regarding this topic. Hopefully soon when I have some time. Thanks for your feedback.

Hi this is very informative. I recently got into the habit of collecting sapphires. I bought a corliflower color heat treated, 17 CT gem. But has an airbuble in it. But with the cut it's made hidden from the naked eye. In your opening how much would that be? This is from Ceylon btw.
Hi DiyodaS,
Really difficult to generalize the price without looking at the sapphire. In the end gemstones like pieces of art is subjective. One person might find the sapphire to be true cornflower color, while some else will not believe so. Just this one factor their can be dispute in price. :)
In general, sapphire prices have been going up recently, so it has been a good investment for good quality stones.

@@ThaiNativeGems Thank you so much for the information Turan! I wish you the best !
Hello friend! Have you any perfect methods to determine the price of Sapphires and Rubies?? Pls explain
Hi Sha,
I wish there was a 'perfect' method. This is my personal method by checking six criteria
1) Carat Weight
2) Color
3) Clarity
4) Cut Grade
5) Treatment Level
6) Gem's origin
All the above factors influence the value of any gemstone. As there are 6 factors, and some are 'subjective' you can see why it can be quite difficult to standardize pricing for rubies or sapphires.

Tarun Gupta, GIA GG
Thank you
Thanks for watching the video! :)
It's alway tricky to buy expensive gemstones.
Diamond ruby and sapphire are also made as a moissanite in the United States.
What do you think about the AIG certification are they good ones
Yes, AIGS certificate is considered respectable in the trade in terms of checking natural status or treatments. For more details regarding the different certificates, pros and cons, I do recommend to reading our blog post: www.buygemstone.info/2017/03/10/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/

great video i have a 999 ct blue sapphire rough how much should i lose if it can be cut
Depends on rough shape, clarity of the rough, etc., Unfortunately like anything 'natural' there is no general answers to these questions.

Any idea how much a 4-5 Carat Cornflower Ceylon Sapphire Unheated A-AA would range from?
We will be making a sapphire video soon of 4-5 carat, 'Royal blue' sapphire unheated from Sri Lanka. Do stay tune. Cornflower will be slightly cheaper but again depends on other 4Cs as well.

I have 10 (around 5-10cat un treated) blue sapphires with me. I recently sold one for 5,000 pounds for a German buyer. I was very lucky because I bought them dirt cheap. I made like 60% profit from the sale.
Very lucky indeed. The prices shown in this video is actually quite low compare to what blue sapphires are selling now, due the lack of supply.
Thanks for sharing your experience.
Best Regards,
Tarun Gupta, GIA GG
@@ThaiNativeGems Yeah! Recently bought 3 natural blue sapphires. One was 1.03ct, 1ct and 1.4ct. Bought them for dirt cheap. If you know where to look inside Sri Lanka. You can buy it for cheap. The best thing to do is networking. As much as possible.
Can you do a ruby value video? And an emerald one?
1 carat ruby has been done here: th-cam.com/video/ornjTJv9pl8/w-d-xo.html
Emerald is in process. I will be uploading it soon.
A jewelry salon I know introduces a royal blue sapphire 5ct at 97k USD. Is it overpriced? (Sorry I didn't get my hands on the other information)
I inquired about rubies at the same weight (5ct) and was told that such ruby will be around 104k-139k USD.
Considered that these stones are natural, is it still overpriced?
Hi Cao,
It really depends on the quality of the gemstone, but yes the sapphire does seem it be priced in higher side. But again we have to look at all six factors 4Cs + OT (Carat weight, color, clarity, cut grade, origin and treatment).
The ruby as it is rarer at 5 carat range might seem more accurate. But again it depends on the quality of the stone.
I actually did make a new video showing some 4 to 5 carat Sri Lankan royal blue sapphire and pricing, which you can see here: th-cam.com/video/eRe__aMUKek/w-d-xo.html.
Personally, I believe a 5 carat royal blue sapphire (top quality) will be closer to 50K USD range around then 100K USD range.

Where would I sell my sapphires and rubies I just came into? They are all natural several 1ct+
If it is certified and stones are okay quality you can sell to any gem collector or dealer globally.
Are these prices for retail customer? Or supplier to a retailer?
These are prices of supplier to a retailer. Not sure what price retailers sell the sapphires for as there is no limit what price they can ask for. Thanks for your question.

What are the effects of a heat trated of thermal treated blue sapphire ??
Effect in terms of? Treatments are used in gemstone to make them look better and make them more saleable.

I have a 3carat oval shape royal blue sapphire,it is heated.But it was very pretty beautiful dark blue clearly. Is it cheaper and has no value? Please someone, I want to know it's value? How much? I got it from my grandmother since about 20 years ago.
Hi Sist,
Is the sapphire certified and if yes, from what lab?
Also, have to check 4Cs in detail to determine the price. Details provided below:
a) Color - It is defined three dimensionally - hue, tone, saturation.
b) Carat Weight - as indicated a '3 carat stone'
c) Clarity - in terms of number of inclusions and transparency of the stone (opaque, translucent or transparent).
d) Cut Grade - In terms of how sparkle and light return the stone has.
e) Origin - Where the blue sapphire is from? Certain origins command a higher price.
f) Treatment - What level of treatment the blue sapphire has gone through? As indicated it is heated... Is it just normal heated or more aggressive chemically diffused or lead-glass treatment?
A lot of this information can be found from reliable third party certificate.
I hope that helps and hope you found our video useful.

How come it's so expensive? In Indonesia a blue sapphire like the princess Di ring with diamonds F vs1 GIA certificated is just $1500-2000, including the sapphire, white gold ring, and the diamonds
Hi Mae,
The ring price really depends on what quality the blue sapphire is?
As stated in the video we have to look at 4Cs+OT qualities (Carat weight, color, clarity, cut, origin and treatment)
Therefore I cannot generalize if it is cheaper in Indonesia or not. I guess the main thing you have to check is:
a) Is the center sapphire certified with reliable third party lab or checked with qualified gemologist?
b) How is the color of the blue sapphire? - Is it Blue Hue, highly saturated, medium tone color range?
c) How is clarity of the blue sapphire? - any eye-visible inclusions or is it 100% transparent (not cloudy, translucence or opaque)?
d) What is blue sapphire carat weight?
e) What treatment is Blue sapphire subject to? Is it treated with chemically diffusion, heat treatment, lead glass treatment? This will drastically reduce the blue sapphire cost.
f) Origin - where is blue sapphire from? Certain origins command a higher price.
g) How is blue sapphire cut? Does have good fire and light return?
Anyways thanks for your comment and good luck with blue sapphire purchase!

I will give you reasonable price
I think you're also missing that these stones very rarely lose any value at all, so if you were looking at something $1500 a career a year or two ago you can easily expect $2000 a carat .. it's not exactly a market for the financially challenged or downtrodden. They are precious and it takes a lot of real world work to finish a stone let alone find it from ore to begin with!
Native cut?
I have a 78 carats natural unheated dark blue sapphire which seems to be from Kashmir but cant be determined 100% from the Swiss Gem Labs I have been certifying it (Region not determinable). Not sure what should the fair value be at all. It is not heat treated and got this dark blue color thing (translucent to opaque). Maybe someone can help me :).
I can help you
Which country’s dollar price you are giving?
US Dollar (or United States Dollar)
Price pls in India distribution pls...
Understanding that it is hard to estimate without seeing a stone but could you please estimate my sapphire, it is 10.15 carat, oval, eye clean no inclusions, good to very good cut, no treatment, and a dark to medium-dark uniform blue color from Ceylon?
Also, I feel like the cut could be improved is it worth having ground with excellent facets knowing that the carat weight will reduce?
Hi Michael,
Though you have provided a lot details, it is still very difficult to judge the price without looking at the stone as the 'color' and overall crystal quality (has fire, transparent, etc.,) really does matter a lot. Also is the stone certified and if yes from what lab?
Also the question regarding re-cutting if worth or not, it is best to ask an expert cutter. Now if the stone does drops below the magic '10 carat' range, this will usually will make the price drop dramatically, so these are trade-offs one has to take a look at.

@@ThaiNativeGems sapphire stone
I have a sapphire stone, I would appreciate it if you could give me a number from vatsap.
What means an impression on a Ring with sapphire mounted in platino Impression is C. U.?
Hi Ramon,
Not sure. Was this comment given in some certificate?
@@ThaiNativeGems thankyou for replying, I really appreciate your kindness, I just find a Ring rounded for a small diamonds and it has a blue stone which is a saffaire and the Ring has a drow with a figure of Diamond and has the letters C u. Thankyou for your attention.!! It's similar to Diana Ring.
Hi , I have a 10karat blue Sapphire. Can u or anyone direct me to where I can get it sold? I have the certification.
U sold it ?
How big of a coincidence is it that you mentioned that Thailand is no longer producing stones, and I happen to find a sterling silver pin marked "THAI W" with 4 tiny black diamond studs and a blue gemstone center piece.
No clue if the stones are genuine or what they even are exactly, but thats one hell of a coincidence.
Rarer to see Thai stones now days. If nice quality prices have definitely have gone up.

Tarun
I just find a ring and im intrigated bc. It look Like a safire rounded by small points of white Stones and its Like a white gold or platinum and it has a simbol of Diamond and C u inside of the ring the blue one Stone in the center look Like a saphire, whats mean the simbols in side of the ring, thankyou i apreciate if you replying.
Hi Ramon,
If the ring doesn't have a certificate I recommend getting it certified that it is genuine sapphire with side diamonds set in gold or platinum. Also usually inside genuine ring band there is a stamp that verify if metal is gold or platinum.

Tarun Gupta, GIA GG
@@ThaiNativeGems thankyou for replying, i really apreciate it and i Will follow your advice , ill lyk everything when i done certification , my best regards.🙏
is the design of the stone well affect the price? despite the color ??
If you mean the blue sapphire's 'cut shape,' yes it does affect the price as well. Though color and than clarity is still the more important factors. For example, if the sapphire has really unattractive color and really bad clarity then the cut shape won't affect the price that much.
If sapphire has normal or better color and clean looking stone, certain cuts like round or square cuts are more premium as they are rarer, and 'more carat weight' is lost due to the cutting process.

How do inclusions affect the price?
Hi Bathiya,
It really depends on the type of inclusions the blue sapphire has. Some inclusions like 'silk' inclusions that give the 'Kashmir or Burma' Sapphire velvety look actually makes the price of the sapphire goes up in value.
Other inclusions, that affect the fire & sparkle (fractures, feathers, black or white inclusions, etc.,) reduces the sapphire prices quite dramatically.

Tarun Gupta, GIA GG
you said the 3rd stone was natural stone because of the angular lines and then said that the last stone was the only one that was not heat treated. so when you say natural it can still be heat treated?
All the stones shown in the video are technically 'natural' as they were all grown in nature. However, some are subject to different types of treatment like heat treatment, chemically diffusion, lead-glass, etc.. These stones are still natural, but more aggressively treated by man to make them look more attractive in terms of color and clarity.
Synthetic stones are man-made stones and these are not natural as it grown in the lab.
In the trade, we call unheated or untreated stones as 100% natural (with no treatment). This doesn't mean other stones is not natural, but they were slightly alter by man through treatments.
Anyways to learn more about 'natural' blue sapphire treatments I recommend reading our blog post: www.buygemstone.info/sapphire-treatment-guide

How much are Burmese sapphires worth when compared to Sri Lankan if unheated?
Both are quite similar in price actually. Generally Sri Lankan blues do look a little 'nicer' then Burmese and that is why they can be priced higher. The most expensive origin for blue sapphires are actually 'Kashmir' sapphire.

Is no enhancement sapphire better or enhanced?
Hi Lilac,
In terms of rarity and price, if both sapphires are of similar quality in terms of the other 5 factors (Carat weight, color, clarity, cut, and origin) then a 'no enhancement' will have a higher value than 'enhanced' one.
However, if you have bad-looking no enhancement sapphire compared with good-looking limited enhancement sapphire (like normal heat treatment) then the enhancement will be better.
Finally, if the stone is aggressively enhanced (lead-glass, chemically diffused, etc.,) then no matter what no enhancement is better.
So, it really depends on the circumstance and the 'level' of enhancement.
Hope that helps.

Good day can you Tell me if I can sell rough Saphire fresh off the Mine (uncut, untreated) or is it better to have it cut, polished etc.?
Depends on rough, and how much risk you want to take. You can never know what quality the rough will come out until gemstone will come out from the rough. So, unfortunately there is no straight answer for this question.

can you help me i have a stone i don't know if it is real or not but the color is the same as my stone here if you are interested just PM we will talk about this stone it is bigger than that pls help me
Hi Robert,
I would recommend getting third party certification to verify your gemstone quality (natural, treated or untreated, etc.,).
We have written about the different labs in this blog post, which you can check here: www.buygemstone.info/2017/03/10/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/

Are the tweezers special? Dont you worry about scratching
Hi,
Great question. :)
Tweezers or metals don't scratch sapphires as they are around Mohs scale 5 to 6.5, while sapphire is Mohs scale 9, which is a lot harder.
Only an equivalent or higher Mohs scale can scratch a particular gemstone... So, Sapphire can only scratch by diamond (Mohs scale 10) or another sapphire.
Now regarding dropping the sapphire or making it 'fly of the tweezer.' That is what I am more worried about as you can chip it if it falls at the wrong angle or the correct force is applied.

I don’t mind violet blue. Give it to me.
Thai adress
Why this is costly
Was explained in the video. Price is base on 6 criteria - carat weight, color, clarity, cut, origin and treatment... Now in India they sacrifice color and clarity dramatically which drops the price.
@@ThaiNativeGems yes correct..becouse here mostly people require only material . Is that sapphire ? is enough for them!.

Hello friend its short and well clear explantion about the gem stones. I herd that kashmir bule sapphires are the most rare stones in the world which high value in the market.
I'm from Sri Lanka and me few friends working on blue sapphire project and we want to find long term genuine partners and buyers for long term business.we buy stones with certificates and sell our stones with Sri lankan government approved sertificates and geology certificates as well. So if you interest in this project kindly let me know.just send me a msg
Yes Kashmir sapphires are the most rare and therefore attract the most price per carat even for unattractive stones.

These prices makes me hate my life
And these prices are a lot cheaper then what blue sapphires are selling now in 'post-covid' world. 😂
Heated and treated gems have a zero value $.
Hi,
It is not true that heated or treated gems have "zero" value. Each level of treatment has some value and we do have to look at other five factors like 4Cs and Origin, which I tried to explain in the video.
The more aggressive the gem is treated the cheaper it gets, but it is still natural and still has some value.
