How to Determine a Value of Blue sapphire? Based on 4Cs plus OT - A Buying Guide 

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.

Thanks for sharing! Sounds like an amazing blue sapphire! Regards, Tarun Gupta, GIA GG

Oh my goodness. I just returned from Key West and saw the same ring. It was gorgeous!!

Thanks!

Thanks for your suggestion. Once I do come across a few Padparadscha, I will make an updated video. Best Regards, Tarun Gupta, GIA Graduate Gemologist

@@ThaiNativeGems I look forward to it 🤗 Thank you

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! Best Regards, Tarun Gupta, GIA GG

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?

Rarer to see Thai stones now days. If nice quality prices have definitely have gone up. Regards, Tarun

Glad it helped!

Thanks!

Hi, yes planning to make one comprehensive video regarding this topic. Hopefully soon when I have some time. Thanks for your feedback. Regards, Tarun Gupta, GIA GG

Glad you found it useful. Hopefully will upload some more tutorial videos soon, if time permits. Best Regards, Tarun Gupta, GIA GG

Can I see the picture ?

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eRe__aMUKek.html. Personally, I believe a 5 carat royal blue sapphire (top quality) will be closer to 50K USD range around then 100K USD range. Best Regards, Tarun Gupta GIA GG

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 Nikil, I do recommend if you believe the stone is unheated & untreated 5.64 blue sapphire from Kashmir to get it certified by one of the premium labs. I actually written a blog post of various different labs which are available which you can read more here: www.buygemstone.info/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/ Now as you are based in New Delhi you can submit the stone to GIA in India and the cost for your stone with origin report will be around INR 20,000 (including various taxes) - price breakdown you can see on there website which I have provided the link regarding lab fees pricing - www.gia.edu/doc/ColoredStones_FeeSchedule_MASTER_Q3__INR.pdf I also checked an unfortunately they don't have a lab in New Delhi but have one in Mumbai (or Surat) - which I am not surprise as these are diamond hubs in India. Address lactation can be seen here: www.gia.edu/locations Now, regarding the stone taking 15 days and paying 'heavy' amount to get tested that really depends on your personal preference. If you are confident your stone is unheated from Kashmir and want to sell it at a 'premium' price any dealer would want a certificate from one of these big labs to verify that it is true (unheated, Kashmir sapphire). Also, personally I find it worth it as it guarantee to me what type of gemstone I have on hand. Finally regarding how much it should be as you can see from our video you have to see the vibrancy of the color (hue, saturation, or tone), clarity (inclusion location and if the stone's crystal cloudy or clean). So, we cannot tell you without looking at the stone. Best Regards, Tarun Gupta, GIA GG

@@ThaiNativeGems Dear Tarun, first of all, it's really nice of you to revert to my message. Your message reflects your utmost level of clarity on the subject. So congratulations to you that you have acquired such a unique skill set. Secondly, I just now spoke to the senior manager of GIA (Mumbai office) and he informed me that, currently they do not offer GIA certifications corresponding to sapphires. They only do it for diamonds and pearls. He advised me to send the gem to the Bangkok GIA lab. I have checked the fees too which is Rs 17390 (this includes origin decoding along with the identification report). Senior manager also told me that an individual gem could also be sent to Bangkok through a courier who has the valid license to send a gem. I will give a deep thought on all this. Anyways do you wish to see the gem, should I send you the pics of the gem in your email id, so that I could have your precious opinion on the credentials of the gem. If yes, please let me know your email id. Regards 🙏

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 Best Regards, Tarun Gupta, GIA GG

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. Best Regards, Tarun Gupta, GIA GG

@@ThaiNativeGems Thank you so much for the information Turan! I wish you the best !

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. Best Regards, Tarun Gupta, GIA GG

If it is certified and stones are okay quality you can sell to any gem collector or dealer globally.

Recommend getting them checked from a reliable third-party lab or from experienced gemologist. Best Regards, Tarun Gupta, GIA GG

Glad it was helpful! Regards, Tarun Gupta, GIA GG

Depends on rough shape, clarity of the rough, etc., Unfortunately like anything 'natural' there is no general answers to these questions. Best Regards, Tarun Gupta, GIA GG

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. Regards, Tarun Gupta, GIA GG

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. Best Regards, Tarun Gupta, GIA GG

U sold it ?

Effect in terms of? Treatments are used in gemstone to make them look better and make them more saleable. Regards, Tarun Gupta, GIA GG

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. Regards, Tarun Gupta, GIA GG

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. Regards, Tarun Gupta, GIA GG

Thanks!

Actually bought from Thailand

India

Can I see the picture ?

I can help you

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. Regards 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.🙏

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/ Best Regards, Tarun Gupta, GIA GG

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. Best Regards, Tarun Gupta, GIA GG

1 carat ruby has been done here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ornjTJv9pl8.html Emerald is in process. I will be uploading it soon.

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. Best Regards, Tarun Gupta, GIA GG

I have a sapphire stone, I would appreciate it if you could give me a number from vatsap.

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/ Best Regards, Tarun Gupta, GIA GG

You can message us at sales@thainativegems.com or fb.com/thainativegems. Though majority of the stones in this video has already been sold. Best Regards, Tarun Gupta, GIA GG

Hi Mj, The purpose of this channel is to educate people about gemstones and not give advise how to sell in particular market. Thanks

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. Regards, Tarun Gupta, GIA GG

Yes the rates are in USD. Regards, Tarun Gupta, GIA GG

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. Best Regards, Tarun Gupta, GIA GG

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. Regards, Tarun Gupta, GIA GG

@@ThaiNativeGems Thank you! is the Ethiopian sapphire is worth to buy? in terms of location ?

Thanks for watching the video! :)

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. Best Regards, Tarun Gupta, GIA GG

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!.

Hi Brenda, I am really sorry to hear of your loss. No value can replace your grandmother's ring, which for sure priceless. I do hope they can catch the perpetrators. Regards, Tarun Gupta, GIA GG

And these prices are a lot cheaper then what blue sapphires are selling now in 'post-covid' world. 😂

Yes Kashmir sapphires are the most rare and therefore attract the most price per carat even for unattractive stones. Regards, Tarun Gupta, Graduate Gemologist (GIA)

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. Regards, Tarun Gupta, GIA GG
