Oh nonsense, I've worn a CZ in my wedding band for years without a scratch on it. And if it falls out? So what! I can get it replaced for a fraction of the cost of what I could for a full diamond replacement!

Gonna be honest I don't think the fake one has a 'bluish tint' and the real one is just more yellow. Real diamonds are rocks. From the ground. They will not be perfectly immaculately clear and colourless. The fake one is probably the clearer one
@@BijouLabThe recognition method you are proposing looks unsafe to me. It's true that the diamond and the CZ have two different reflectance indices, but there's not just one standard round cut on the market (for example all the variations of hearts and arrows cut) and in any case to increase the reflectance of a CZ you just have to make a deeper cut, so you can no longer see the dot. It's easy to be fooled. To me, the best "method" to tell stones apart will always be gemmologist 😊
Yes, any stone can be made worth more by creating mirroring, you want to avoid windowing. So really you are testing the angle of the cuts...ideally a diamond would not have any mirroring but that's not necessarily true if cut by a novice or as another person mention have the old mine cuts etc...But I guess the better cut it is the more it's value. H/e diamonds can be recut if that's what you are seeking. I will test this to see how it works on my cut stones regardless of type. Diamonds aren't actually that rare anyway, so their value is what people are willing to pay/the amount of skill that went into cutting it.
The real one is low quality tho, you can see the clarity and color aren’t the best. 2 of the 4 c’s aren’t properly met here for a higher quality Diamond.
The quality of the 4c's doesn't affect the refractive property of a gemstone. With that said, it is an F color and VVS clarity so the 4c's are "properly met", whatever that even means.
@@BijouLab I think my wording was incorrect, let me refreame; A diamond with a poor cut will reflect the light poorly; (so yes, it is the cut that is more important) this in turn can make a diamond appear smaller or duller.

@@sydkoy608 yes they are standard gradings used to evaluate diamonds, what I meant was that there isn't a cut off point, like if a stone doesn't "properly meet" certain levels then it's not a diamond.There also isn't really a universal 'standard' of what makes a good diamond, of course the higher grade on clarity and color the better/more expensive, but an overall evaluation kind of depends on the person, there's no defined line or bar to "meet" from what I know at least.

As long as the stone isn't flat on both sides it should work (think emerald cut for what wouldn't work). Think of the classic prism splitting white light into multiple colors - light is refracted or bent through objects depending on their properties.
@@livewellwitheds6885 but if the diamond were flat and thin, like a rectangle/emerald cut, it wouldn't refract the same way. This diamond is triangle shaped.

@@RainCheck797 it depends on how it's mounted.. if you can see the bottom of the stone, yes, but otherwise no? You know the mounting where there's no prongs, just a band of metal around the stone; it would work on that
For those of you who are curious, the reason is because of "refraction". This is also why diamonds "sparkle" or "shine" and here's how it works. Carbon disperses and absorbs light. That's why most carbon is pitch black (think pencil or charcoal). However, when you line all the atoms up in the same direction using intense heat (thank you, volcanoes) you can shave the edges into "facets" that disperse incoming light uniformly in the same direction. Even if the paper is thin enough to allow light to pass through from behind, said light (now colored by the dot) cannot pass through the top facet of the diamond (the "table") to reach the part that you are looking at (the underside, known as the "pavilion"). Instead, that light gets bounced back toward the paper. Glass (made of silicon) is the opposite--which is why even though a window in your house is flat you can look through it from almost any angle and the view doesn't change. The "CZ" she mentioned is cubic zirconia (ZrO2). Ironically, the zirconium in that formula is an odd metal that makes the "CZ" very very strong, but it's the oxygen in that formula that leaves enough space for electrons to pass through unhindered in a glass-like manner.
@@BijouLab I’m glad to hear that! It’s still a bit confusing in the grand scheme of things though.

@@letscarpethisdiem1988Lab grown diamonds are considered real vecause chemically and structurally, they are exactly the same. The lab simply speeds up the process of diamonds being made.
as much as i think diamonds are tacky i love this from a physics stand point this works because the refractive index (how much light slows down within a substance) is higher for diamond (2.42) than it is for CZ (2.16), causing the light reflected off of the dot to refract away from your eye
she is also likely using red opposed to blue because red light's shorter wavelength causes it to interact with the diamond molecules more, making it refract further
Lab-created diamonds and mines diamonds are both real and share the same chemical and structural properties. I’d rather say that we properly replicated an element of nature. In real diamonds (which both lab and natural are), the light will bounce in many different directions and not a straight line, so you wouldn't be able to see the dot through a real diamond. The reflectivity of a diamond refers to the amount and quality of the light reflecting off of the stone.
While I agree with you about natural diamonds being basically a scam, I think this can be a good thing to know if someone is unsure about a stone. CZ needs different care compared to a diamond and it'd be a shame to be careless and scratch the stone thinking it was a diamond. :/

Not to mention designer purses are pretty ugly. I think ATP, the elites are just trolling to see what the can brainwash people into wasting their money on next
I never realized how many people think that "cubic zirconia" is a word for a lab-grown diamond. It's not! Lab-grown diamonds and mined diamonds are both diamonds. Cubic zirconia is a totally different thing-it looks similar to diamond, so it is often used as a cheaper substitute. But it is not diamond. Cubic zirconia is the cubic crystalline form of zirconium dioxide (ZrO2). Diamond is a solid form of the element carbon (C) with its atoms arranged in a crystal structure called diamond cubic. Zirconium has symbol Zr and atomic number 40. Carbon has symbol C and atomic number 6. These are entirely different elements!
She's holding them upside down and right side up aka she's holding the cuts the opposite direction. That's why one slants to the side and the other slides across the paper. The cut of the crystal matters in the a lot in the optical illusion and clarity. Also CZ just means Cubic zirconia, which is a lab grown diamond.😅
My grandfather worked in jewlery, i was able to tell just from the stones. You usually can't tell 100% just from a look, and i most certainly couldn't grade it, but diamonds are fascinating.

This only works with a modern round brilliant cut. Old mine cuts and European cut diamonds will show portions of the red dot and are still natural diamonds.
This is a function of the index of refraction and the cut of the stone. They could do the same thing with the artificial diamond if they alerted the cut. If they altered the cut you would notice the shape was different. In the end if it looks good then it doesn’t matter. Buy what you can afford and ignore the rest.
While neat, it would be more reasonable to do the test using the same cut configuration on both the CZ decorative stone and the diamond. You can get some really intricately cut CZ from specialized sellers that would be nice to put to test.
@@user-kb7eg1ln9k that makes zero sense because the light refraction in a diamond like that is different than one of a square. Meaning that even if the dot was square too, this method would not work. I am simply asking “What are other methods”?

In real diamonds (which both lab and natural are), the light will bounce in many different directions and not a straight line, so you wouldn't be able to see the dot through a real diamond. The reflectivity of a diamond refers to the amount and quality of the light reflecting off of the stone.
My little cousin fell asleep watching this on my phone😭
I would take ice cream making shorts over this any day
Good for you? Click the 3 dots and then “not interested”
"Oh no, my gem wasn't mined by a child slave"🙄
the fake looks so much nicer
Cracks me up that cubic zirconia are considered "fake" only because the fiat value of natural diamonds is artificially (and arbitrarily) inflated.
Diamond is also yellower than the fake
Due to TIR ( total internal reflection) as diamond has higher refractive index than air
But what if it’s already set in a jewelry piece?
i dont trust this test
So? What makes the diamond special? Is it the suffering caused by mining it? I'll take the cz any day.
While I agree with you about natural diamonds being basically a scam, I think this can be a good thing to know if someone is unsure about a stone. CZ needs different care compared to a diamond and it'd be a shame to be careless and scratch the stone thinking it was a diamond. :/
Plus it's good to know the difference if you ever do by a real diamond thing so you don't get scammed
Yeah what the previous people said. It’s also about not pay diamond prices for cz. Though blood diamonds are awful and there are much prettier shiny stones

Why would anyone in their right mind want a natural diamond in this day and age?
Literally EVERYONE knows about what's happening in 🇨🇩Congo🇨🇩 right now, actively choosing to buy a natural diamond is diabolical and should be punishable
@@frenchrevenge6406 i don't even know what you're talking about or where that is
Imagine needing a felt tip to know if you should be happy with your shiny stone. Seriously we humans are dumb, really give false value to things
I mean, not only do we unnecessarily value it, but it is explicitly known that the diamonds have an artificial value due to them being hoarded and released less than normal, and propaganda/marketing campaigns that promote their value 😊
Yeah, but where would we be without the unnecessary value to things (a happier place, also both that and diamonds are still pretty cool)
Idk, I think I'd be pretty mad if someone tried to sell me glass for diamond prices. Even though I'm not particularly attached to diamonds in the first place, and think plenty of other stones are prettier
@@raerohan4241that’s what I’m saying the people saying there’s no point and they’d get a fake one cuz it looks prettier are confusing me.. why pay for a fake diamond but at real diamond prices??
I feel the same way about most "luxury" things. If the rest of the world didn't know that purse cost $2500, or the car was $100k, would they still buy it?
Not to mention designer purses are pretty ugly. I think ATP, the elites are just trolling to see what the can brainwash people into wasting their money on next
I never realized how many people think that "cubic zirconia" is a word for a lab-grown diamond.
It's not! Lab-grown diamonds and mined diamonds are both diamonds. Cubic zirconia is a totally different thing-it looks similar to diamond, so it is often used as a cheaper substitute. But it is not diamond.
Cubic zirconia is the cubic crystalline form of zirconium dioxide (ZrO2).
Diamond is a solid form of the element carbon (C) with its atoms arranged in a crystal structure called diamond cubic.
Zirconium has symbol Zr and atomic number 40. Carbon has symbol C and atomic number 6. These are entirely different elements!
She's holding them upside down and right side up aka she's holding the cuts the opposite direction. That's why one slants to the side and the other slides across the paper. The cut of the crystal matters in the a lot in the optical illusion and clarity. Also CZ just means Cubic zirconia, which is a lab grown diamond.😅
My grandfather worked in jewlery, i was able to tell just from the stones. You usually can't tell 100% just from a look, and i most certainly couldn't grade it, but diamonds are fascinating.
This is the easiest way I’ve seen so far
Probably because it's what you're used yo seeing. You'll tend to favor whats more familiar to you, and this goes with anything. It's why people usually tend to perfer a song version they originally heard, whether it be a cover or the original. Obviously, there are other factors, but familiarity is a strong one.
very cool video!
I already knew the answer though because the average diamond is much smaller than average CZ (for cost)
I figured the real one was the smaller because diamonds the size if the fake one are way too rare to not be in a museum or one some billionaire's ring big real diamonds cost an unquestionable amount of money
Do the other colors work
Blue?
Yep, the refractive property of diamond doesn't change even if it is a colored diamond.
This only works with a modern round brilliant cut. Old mine cuts and European cut diamonds will show portions of the red dot and are still natural diamonds.
This is a function of the index of refraction and the cut of the stone. They could do the same thing with the artificial diamond if they alerted the cut. If they altered the cut you would notice the shape was different.
In the end if it looks good then it doesn’t matter. Buy what you can afford and ignore the rest.
I could tell immediately even before the dot test.
What about a real one from a glass one?
the refractive index of a diamond is still more than of glass (or of a plastic) so it will still be noticeable
I'm not rich enough to have this problem
Also, the yellow tinge is a good indication.
While neat, it would be more reasonable to do the test using the same cut configuration on both the CZ decorative stone and the diamond. You can get some really intricately cut CZ from specialized sellers that would be nice to put to test.
What if it’s square? And large? What do I do then?
Try to draw a square
@@user-kb7eg1ln9k that makes zero sense because the light refraction in a diamond like that is different than one of a square. Meaning that even if the dot was square too, this method would not work. I am simply asking “What are other methods”?
@@ConsciousTaleError I never said it would work I said to try it
@@user-kb7eg1ln9k and I was asking for a different method. Thank you, I appreciate you trying to help but I genuinely wasn’t thinking of trying something pointless. /nm
I do believe this completely depends on the cut.
You don't need a test between these two particular stones. You can tell just by looking
The moral of the story is, no one is going to be able to tell a CZ from a real diamond if youre simply wearing it in public. So save your hard earned money on something thats actually worth it. 😂
The left one is prettier
Good, because Diamond don't have real prices anyway
@@Lemony123 yeah, people who sell jewelry hype up this carbon rock so much lol
I think they literally meant the diamond one is prettier because it's on the left? @@Lemony123
What's even worse is that diamonds are a really brutal industry, look up the DRC
Good to know. Not that I would ever have to test though.
Let me just grab my diamond stash to check 😂
Wow im 55 years old and I just learned this today...lol
I think colored stones are prettier. Diamonds are a marketing scam, anyway. If it's pretty, who cares if it's man made?
the people trying to convince you to buy diamonds care 😭😭
I knew without the test. The fake one looks cloudy af. Real one looks..real
Do you have to use a red pen, or can you use any colour
The real one has a bit of a yellow tint while the fake one has more of a blue tint
I could tell immediately before the DOT test
Didn't need the test for this one
Hard to do a dot test when your stone is sitting on a ring though. Doh!
I will literally never need to use this but I do think it’s really good to know anyway.
Correct me if I'm wrong but doesn't the effect depend on the cut of a diamond? Like would a raw one pass this test
Just curious, how does the dot test go for other stones such as moissanite or white topaz or white sapphire
To people who is wondering what is cz its cubic zirconia ots a fake diamond
The TIR will block the red from passing through. Consider it a crowd fighting on a highway and vehicles can't pass through
love how the cubic zirconium is clearer XD honestly idc if it's real as long as I like the look of it
I immediately knew because of the lines
Great but what if it is in a ring??
The fake one is so nice! Plus wearing diamonds around gives me HIGH anxiety 😅 what if something happens to them?!
I already knew which one was the diamond by which one was smaller
The easiest is that diamonds can scratch glass. But the diamond market is not worth the cost so just buy a different gem
This only works in a round brilliant cut. If you had a rose cut diamond, the effect would be the same.
On clarity you can see that the right side is a real diamond even without the red dot
As a lover of cubic zirconium, this wasnt that hard tl differentiate even without the red dot test lol
Don't care, still shiny, hella cheaper.
It’ll get cloudy and scratched when worn.
cheaper to replace.
@@BijouLab Then I'll replace it, still cheaper
@@emmanuelleraynal6997instead of buying a real one once and never having to replace it like the fake one that has to be replaced every other month cuz it got scratched and foggy. Hm..
Wow but how did I know which one was the actual Dimond before I even saw the test
That more depends on how it's cut, not if it's real or not
... Top clear - top wesselton.
Depends on how you cut it.
I instantly noticed the real one
Can you do a different colour🌈... like purple 💜
They are of different sizes and cuts, so obviously they bend light differently.
I thought this only works if it's cut in a certain way?
Put them into mineral oil. You can still see the diamond; the CZ will disappear.
Lmao a diamonds value is just as fake as the fake diamond. We need to stop giving value to something so worthless
This test is faulty as it depends on the shape of the cuts in determining if you will see the dot or not.
After this I want the fake one😂
COOL THANKS FOR SHARING
I knew the one on the right was fake before you even did that lol
It's weird, since they always say "crystal clear". Even in reality crystals aren't clear.
Neverunderstood why people use diamonds if glass or similar fake diamonds are cheaper to buy and still beautiful
Because diamonds stay beautiful longer. Glass and CZ will dull and scratch over a few years daily wear. It’s not a problem for jewelry that doesn’t get a lot of wear, but for something like a wedding ring that you want a lifetime of wear from, CZ is not the best choice.
Sooooo.... what about lab grown? Are they opaque like a (natural)real one or transparent like the Zirconia?
