yeah she really gets straight to the point. thats appreciated. when someone is straight to the point, its because the video isnt about themself. these videos are needed, because Opals got very popular after that Adam Sandler movie Uncut Gems came out.
Nice video, but I think the maths is wrong... she is dividing the weight of the stone in air by the weight of the stone in water alone, NOT by the weight of the stone in air MINUS the weight of the stone in water (as is shown in her example equation). In the case of the dyed Ethiopian stone, the equation should read: 19.45 carats/(19.45 carats - 11 carats) = a specific gravity of 2.3, not 1.7. But the video is very helpful -- thanks for posting!
The truth is treated gemstones have more risk involved in it. Treating opals have the risk of cracking during treatment process and many do during the performing the method. Also, it involves more work to treat the opal. Not to mention if the opal is faceted then it is even more difficult to get it treated because faceted opals have even more risk of cracking. Cabochons are easier to create but faceted opals are valued at a much higher place for these reasons. I respect the other information he has in his video but he is definitely incorrect about the treated opals. Good job calling him out on this.
i still haven't found a dye for ethiopian that works. i've treated it with base to get sodium ions into the framework and then introduced different metal ions to some interesting effects. but no black. i tried india ink, they got wet but not black, those are some small pores! don't worry i would disclose to people that i did what i did.
Some great information. Some of the Wello opal looks great, but I always stay away from the dyed ones. Will the Wello opal weigh in water be affected by the amount of water it contains already? Just the ethiopian opals absorb water easily.
In order to make a fair comparison they should have compared treated and untreated opals from the same area (compared Ethiopian with Ethiopian and Australian with Australian). This video gives the viewers the false impression that Ethiopian opals in are fake. They did not even mention once that there are natural black opals in Ethiopia. Quite disappointing for a video that is supposed to give information.

I'm disappointed to see this vdo. Thou the information is good but seems like you are running your own business of Australian opals so for u all ethopian opals are fake.
Most Ethiopian opal THAT IS black is dyed or smoked. Fact. And unless you have a Lab Cert by experts like Stone Lab Groups it is dyed. Caution opal auction buyers. I have sent many black Ethiopian opal sold as Not Dyed only science proving otherwise. I have been cutting....buying..,,making..,,selling fine jewelry since 1969
Hi, are all treated wello has a cherry red color when you light a yellow flashlight inside it? I have a 2mm tiny black opal. It doesn't show any matrix but doesn't look cherry red color when I put a torch inside it. What could it be?
To be honest all foreign buy from Ethiopia! But this video wrong impression about Ethiopian opals ! So do ur won business let us do our own business ! Our opals best opal on earth 🌍 u will see next 5for 6 years we control world market!
thank you for sharing this informational video.
thanks for posting this. people really need to stop being deceptive but we know this will never happen
Thank you. I appreciate your valuable insight.
this was a really helpful video - thank you guys - Natassa clearly knows what she's talking about!
yeah she really gets straight to the point. thats appreciated.

Hi guys ! I’m a very big fan of y’all’s work and the things you guys post on opal auctions ! Great video !
Are natural, not dyed ethiopian opal also floureszent?
Nice video, but I think the maths is wrong... she is dividing the weight of the stone in air by the weight of the stone in water alone, NOT by the weight of the stone in air MINUS the weight of the stone in water (as is shown in her example equation).

what shes measuring is the buoyant force of the stone in water. the weight in water is ~ the weight in air minus the buoyant force in water
Yeah, the math is wrong. It is 2.30, not 1.7
5.8 /(5.8-2.9) = 2.0 and 19.45/(19.45-11) = 2.3

this video is like 40 percent correct....
Thank you! Any advice on Indonesian opals would be much appreciated!!!
Amazing video 👍👍 thanks guys
So is it fully black inside? I mean if we cut that smoked black opal, is inside of that smoked black opal is also black or what?
Very interesting info! THX!
Thanks for doing this. I don't know what my problem is with Opal, but I got it bad.
Very much thank you for this video! I know it has been really requested on the opal reddit community.
Omg guys thank you for this I have been looking for this info for a while
Great demonstration. Thank you.
This video is very valuable 😮
uv test is the best and easiest way i think.. thanks for the video 👍

Hi, thank you for the video, do you know if a clarity enhanced opal by being heat treated changes the value of a stone and by what estimation?
🤣🤣🤣🤣🤣🤣
Dyed smoked opal to me a fine jeweler is WORTHLESS.
i still haven't found a dye for ethiopian that works. i've treated it with base to get sodium ions into the framework and then introduced different metal ions to some interesting effects. but no black. i tried india ink, they got wet but not black, those are some small pores! don't worry i would disclose to people that i did what i did.

Price?
I have sone question sir if its okay with you
thank you for the video!
Use a UV torch
Seems like a Propaganda for Australian Opal. Please see your calculation, The specific gravity of Ethiopian Opal is 2.3 based on your own formula.
In order to make a fair comparison they should have compared treated and untreated opals from the same area (compared Ethiopian with Ethiopian and Australian with Australian). This video gives the viewers the false impression that Ethiopian opals in are fake. They did not even mention once that there are natural black opals in Ethiopia.

Yes, indeed, the calculation in the video was wrong!
yeah pretty sketch

Did you forget your own mathematical formula? Cos 5.8 /(5.8-2.9) = 2.0 and 19.45/(19.45-11) = 2.3
Do these test also apply to Opal already mounted in jewelry?
🤣🤣🤣🤣🤣
Very informative !
😱😱
Thank you very much for the explanation, so I can know the difference between real black opal and fake black opal.
Great video! Thanks.
She shows an interest in music

Thanks so much madam
Please get a better microphone the echo is terrible sounds like you're in a bathroom.
You forgot the triplet opal..
Немыслимая красота!!!!
Строгий "чёрный" + озорной "радужный" в одном камне.....
Несочетаемое сочетается, и, получается, ВЗРЫВ эмоций!!!!!
Вряд ли, кого-то, этот камень, оставит равнодушным....
Muy bonito opalo pero cuál es la opinión que tienen sobre el opalo mexicano el opalo de fuego
I'm disappointed to see this vdo. Thou the information is good but seems like you are running your own business of Australian opals so for u all ethopian opals are fake.
Ok
ကျောက်ရောင်းသူများရောင်ကောင်ကြပါစေ
Wello is awesome opal but fakes and to much water in some, spook me away.

Speaking into a barrel is probably NOT the best venue for this explanation.. lapel mics are cheap..
