The popularity of Opals has exploded in the last few years. Buyers always need to be on the look out and do their best at knowing how to identify fake Opal.
In this video you will see real samples of natural, treated and fake opal and learn how to see the difference and test them.
Thanks for watching, Opal Lovers.

this was a really helpful video - thank you guys - Natassa clearly knows what she's talking about!

@user-nj6gx6we1w 3 ай бұрын

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.

I have plenty of natural black ethiopian opal, for many years the industry refused to aknowlage that black ethiopian opal existed because it cut into their profits.

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!

@bonusben3486 3 жыл бұрын

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

@amberty2002 3 жыл бұрын

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

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.

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.

@GeminiSound 2 жыл бұрын

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.

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
