I found a gorgeous deep dark blue sapphire once in key west and the salesman told me to take it outside to the sun and it absolutely blew me away it was gorgeous

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.

[@ThaiNativeGems]

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

[@toby-7323]

@@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.

[@DiyodaS]

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.

[@ThaiNativeGems]

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

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.

Hi, what colour sapphire do I have when it is darker blue but light blue in the sunshine? Thanks

[@ThaiNativeGems]

You have to check the sapphire in neutral light setting which means in near sunlight (not direct strong sunlight) or daylight lamp in neutral white and gray setting (this is what the labs use to judge color). Thanks for your question. Best Regards, Tarun Gupta, GIA GG

[@hikingfanmttaranaki]

Thank you

[@caobangtrinhtran5656]

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?

[@ThaiNativeGems]

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: kzbin.info/www/bejne/m4PIkJKXgrp-m80. 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

[@sistnaing4]

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.

[@ThaiNativeGems]

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

[@c_losgarage71]

Where would I sell my sapphires and rubies I just came into? They are all natural several 1ct+

[@ThaiNativeGems]

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

[@maximhollandnederlandthene7640]

It's alway tricky to buy expensive gemstones. Diamond ruby and sapphire are also made as a moissanite in the United States.

[@pravinpandya3033]

Are these prices for retail customer? Or supplier to a retailer?

[@ThaiNativeGems]

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

[@visawajeetsingh9042]

What do you think about the AIG certification are they good ones

[@ThaiNativeGems]

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

[@NikhilGuptaAstrology]

I have a 5.64 carat blue sapphire, no inclusions are visible to the naked eye but definitely has all the required inclusions like cavities, crystals, rutile needles, traces of other mineral etc when seen under the magnifying glass, it has dark navy blue or corn flower blue colour, very transparent, has good color zoning etc. Jweller from whom I purchased this gem in 2013 is my trusted relative who informed me that the origin of this gem is from kashmir and its unheated, untreated but the certificate did not mention anything about its origin or treatment. I wanted to know about its actual price and wanted to sell it. I want to have a GIA certificate for this gem so that its actual origin and treatment information could be decoded but I do not know the procedure for the same. I am based in Delhi, India and also reluctant to send this gem to a lab for week or 15 days and pay a heavy amount to get it tested. Please guide what should I do?

[@ThaiNativeGems]

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

[@NikhilGuptaAstrology]

@@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 🙏

[@thegame3265]

[@anthonybost8646]

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?

[@ThaiNativeGems]

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

[@shabai8949]

Hello friend! Have you any perfect methods to determine the price of Sapphires and Rubies?? Pls explain

[@ThaiNativeGems]

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

How much are Burmese sapphires worth when compared to Sri Lankan if unheated?

[@ThaiNativeGems]

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

[@msk3905]

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?

[@ThaiNativeGems]

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.

Is no enhancement sapphire better or enhanced?

[@ThaiNativeGems]

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

[@jesseechavarria2411]

Good info great video, thanks for making the video.

[@natiman5850]

is the design of the stone well affect the price? despite the color ??

[@ThaiNativeGems]

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.

Are the tweezers special? Dont you worry about scratching

[@ThaiNativeGems]

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.

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

Heated and treated gems have a zero value $.

[@ThaiNativeGems]

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
