Thank you. First video I've found which is actually educational.
Wow this video and channel is so informative I'm surprised more people haven't seen this. I'm definitely watching everything before I get my wedding ring and may even look into my engagement ring
Thank you so much... i have learnt alot and i really appreciate the time you have taken to create this video.
The main thing that i have be assured about... is that my jeweller is a very honest man and really was looking out for my best interest.
I've been wanting to learn this. Thank you🥂
Excellent Knowledge! Thank You!
BEST information on diamonds I've seen so far....thank you so much!
If you love rocks and diamonds check out this video of Rare Diamonds of the World: ua-cam.com/video/GBHuYyqm8VA/v-deo.html
I guess it is kind of randomly asking but do anyone know a good website to stream new series online ?
@Arthur Wesley i watch on FlixZone. You can find it on google =)
@Makai Yosef yup, have been watching on FlixZone for since april myself :)
@Makai Yosef Thanks, I went there and it seems like they got a lot of movies there :D I appreciate it !
Love this!
Love your videos
Thank you SO much. 🌷
Excellent video, very helpful. Thank you.
This is what I stress to my buyers, the cut is exceptionally important!
@@aamitparekhh I think you misunderstand.
@@aamitparekhh Cor Gems is informing their customers of the importance of a diamond's cut grade. How do you conclude he/she is stressed over their diamonds?
Both were the exact same cut tho lol yet diamond A is supposed to be better despite both diamonds being triple excellent and the only difference is B having superior color yet once again diamond A is supposed to be better for some reason 🤔
Great.... thanks for the video
BEST information on diamonds and very educative.Thanks.Please also show address of your Labs where anyone can pay and get the detajls confirmed,
No not surprised B is much whiter to me, A looks darker to me. I also can see that A has a much better cut, B’s sparkle is cloudy. I’m not a gemologist or have anything to do with them but is this not clear to everyone?
good info!
I enjoy listening him teach
Can you do a detailed video on heart shaped diamonds and how to tell what to look for and color to look for?
yea good question
Love your comment. Give me better idea of comparison. Thank you very much
Diamond A - F triple excellent cut looks great!
Question, holding everything constant with diamond A, will we be able to see a noticeable distinction in color between an F and a G to the naked eye?
C, both are lovely.
So if the ASET diagram can be the most effective measurement of light performance, why do we care about the 4Cs? If the diamond merchants all show the ASET diagram, the consumers should have a much easier time choosing diamonds. Is it because they deliberately avoid showing the diagram and want to scam people?
@JannPaul... First, of all thankyou! Great educational informative video, very helpful! Please clarify does GIA issues such certificates to those diamonds with light leakages? Even though GIA certificate says "Excellent" in cutting, Excellent in clarity and Excellent in symmetry. Please shed some light on this. Thanks
Hi Rehman,
Thank you for your kind words!
As GIA does not grade the light performance of the diamond, diamonds could still have light leakages even if they are graded as excellent on the certificate.
We uses the Ideal and ASET scope to view the light performance of the diamond, Excellent on the GIA can still be a very loose term.
It could range from Super Ideal Cut, Ideal Cut and a common Triple Excellent Cut.
In addition, the Ideal Cut and a common Triple excellent diamonds are traded at a cheaper price.
Feel free to email us at sales@jannpaul.com if you have any questions!
Hi Paul, will moissanite have the light leakages like Diamond B even if its heart and arrow and 3EX cut?
Would be nice to see the gemex specs for those 2. Would it inform of those differences which GIA doesnt?
@JannPaul.. Did fluorescence in diamond 'B' played any role in light leakages? Or it was just badly cut? Over the internet I have heard the positive and negative aspects of fluorescence in diamonds. Looking forward to your brilliant reply.
Abdul Rehman fluorescence usually makes the diamond look whiter than the grade. In natural daylight it may look cloudy.
Both have the same cut.
This makes me wonder about the difference between them in a chemical composition? Impurities of each in their respective quantities.
Why is space dark? The shorter the wavelength of the light, the darker it is or the dark light refracts to the medium and caused the prism, the darker diamond B didn't emit much prism as the light passes through it because it has higher refractive index than Diamond A. When the refractive index occurred in the Diamond B, it showed its luminiscence of the refractive index, light, speed of light and the velocity of light, as the light bends it hits other angle and facets in the diamond.
The Diamond A has much dispersion of the light. Dispesion cause more rainbow colors to appear and be visible.
What is authenticity of gis diamond report? Is it possible to find a 50 Carats D Flawless diamond with gis certificate? I really doubt.
Hi mr.jann i have some question sir.i found stone its look like pink diamond i try fog test but its not fogging even 1 second can you help me sir to know if this fake or real pink diamond?
*naked eye you can't tell the difference*
I could tell right away at the first time I seen it
you cant tell shit hahaha
Bullshit
So I noticed the difference on the gia report showed that the f color had fluorescence saying none and the decolor had fluorescent saying medium blue and when you showed the light differences on which retain light and whatnot at the top it said fluorescence but I didn't hear much about what that actually means can somebody shed some light on that no pun intended?
So what kind of cut did diamond B have?
The lighting at 6:58 - 6:59 obviously changes when the presenter goes from showing "stone a" and "stone b" also the distance from background changes. Why is this?
Please share the ideal cut proportion parameters to weed out the not so (really) greatly cut diamonds. These idealscope images are not provided generally by the stores or even online (except the super ideal cut/trademark cut diamonds).
Go on Beyond4C and you will get a guide on how to choose the best round cut diamonds.
JannPual is a great place...
wow..
My guess was correct, I chose Diamond B.
Why don't you have them on white white paper upside so you can see the color ?
I'm one of your big fans, I want to ask, what does gemex lighting mean? is it like an ordinary led light?
GemEx, a key player in diamond analyses, has established the concept of scientifically quantifying the Light Performance of diamonds!
GemEx scientifically and objectively measures and reports on a diamond's ability to reflect and refract light - which is what makes it sparkle...
Take a look at
gemex.com/certified-diamonds/understanding-light-performance/
ok...the 'D' has a crown angle of 36.0 degree and a pavilion angle of 41.0...that combination falls in the excellent cut range for both GIA & AGS...the 'F' crown angle is 34.0 w a pavilion angle of 40.8...that combination falls in the AGS ideal cut range...and GIA excellent cut range (since GIA does not have an ideal cut grade)...in addition the 'D' is deeper than the 'F' stone...kinda apples and oranges if you ask me!
how can you tell if the cut is "super ideal" on the GIA certificate? I don't see where it would say it
Hi John, unfortunately, GIA does not grade the light performance of a diamond. Hence, you would not be able to tell if a diamond is a Super Ideal Cut quality, based on the GIA certificate alone. You would need to check the light performance of the diamond under the ASET scope, and its optical symmetry under the Hearts & Arrows scope.
In the meantime, you can check out this video, where we explained what you should look out for in a GIA certicate,

super ideal ? hahaha who told you that one, they must have seen you coming lol
Diamond A has the better cut.
So are you stating that the diamond cutter is the most important person in the process when determine which diamond shows more life and sparkle regardless that one of the diamonds is D color and the better more sparkle is the diamond that is F in color. Right now when I press on the responses after the statements I can’t read the statements . .. this happens to me sometimes on UA-cam and other times I’m able to see the responses and I don’t know how to fix that. But I think I’m correct in stating that the way a diamond is cut can make all the difference in making a diamond brighter. Very well cut diamonds by expert diamond cutters makes the difference in the sparkle. I inherited my mother’s diamond which was bought in the diamond district in New York City on 46th street in 1961. It is extremely sparkly and was not treated with fluorescence and though it is graded G color it sparkles almost like a D or E color because it is cut so beautifully. It also looks larger than it is because the table of the diamond is slightly broader on the top of the diamond making it appear larger than what it actually is.
It can be cut excellent but have blemishes and inclusions which would bring it to a lower class
B. a color of diamond D is perfect, A. a color of diamond F colorless not bad, but diamond A look clear eye, for me i choose F color is batter the light is perfect then D color, i don't know why! the cut, clarity, polish, symmetry are excellent, or about deep, table of diamond ? can you tell me about that.
Hi Sar, thank you for your comment!
Diamond A (F Color) has a much better light performance than Diamond B (D Color). Hence, Diamond A appears much brighter / ''whiter'' due to its strong light return. Both diamonds are GIA Triple Excellent stones. However, GIA does not grade the light performance of a diamond. What this means is that a poor light performing diamond that suffers from massive light leakages can still be graded as a GIA Triple Excellent stone.
For more information, you can check out our other video, ua-cam.com/video/cBfd99gsydc/v-deo.html
Florescent grade was much better is diamond A.
USFanlovesjiwoo Exactly. The medium flourescence, especially in a high color like D, is what's causing diamond B to look hazy.
It has a blue reflects inside
looks like christmas light
Thing you so gia.thank you so must turn.
Its has best reflects
I have a diamond but how do I know its the best grade
I really don't care for the heart and arrows look black lines in diamonds for contrast. I like b better not as vivid on the light but it's lest contrast and look brighter.
i actually think diamond A is darker then diamond B.
So where does the huge leakage ring in stone B come from, if the cut is excellent?
Excellent is a very loose description, having a wide range of allowable dimensions. To get a truly excellent diamond you need to know the dimensions the diamond is cut at regarding pavilion, table, depth, crown etc. All this information should be on the certificate which is why it's important to see the cert before buying. The ASET also gives really good information and should be viewed before purchasing. This link can help explain more regarding cut proportions:
yourdiamondteacher.com/diamond-4cs/cut/perfect-super-ideal-cut-diamond-proportions/
@@ronjon1188 Under what "type" of light does GIA examine a colored "fancy" diamond? I want to judge the color of my stone before sending it to them.
Your website doesn't work. I would love to get a diamond from you
Maybe that's a sign. Look for quality service & recognition
How we can find out that diamond is ideal or super ideal ? Just trust the jeweller?
dd bin never trust the jeweler unless you did an overwhelming amount of research. Know the ideal proportion(girdle, table %, depth %), color, clarity of your desired shape before you go to the jewelry store.
Is the H - I diamond of good value/color?
G-H is ok but dont go lower then H,too much yellow after that
unto diamond g-h you cant tell the difference under naked eye
I have H and im really happy!
the d color has medium blue fluorescence
Hi Kode701,
Thank you for your comment! Yes, Diamond B has medium blue fluorescence. Fluorescence are boron particles that may cause the diamond to appear chalky/milky/oily under UV light (Sunlight). In addition, blue fluorescence may give a diamond a slight blueish tint under UV light.
However, these visual affects would only be apparent under UV light (Sunlight). In the video, the diamonds were taken indoors (under fluorescent light and LED light). Hence, the fluorescence in the diamond would not have any visual effects in the comparison video.
Perhaps I should have mentioned this in the video. Thank you for bringing it up! :)
Cheers,
Casey
👍🏼👏🏼👏🏼👏🏼
White leakage and high florescence do play an important role in affecting brilliance,fire and scintillation. So basically, we are referring to Cut of diamond which is actually affecting color. Honestly,I would buy A to wear and for investment too.
But both are the exact same cut lmao the only difference is the color.
@@budstopseasyroadspenceno, they are not the same cut. On paper, they’re both excellent cut, but that’s only because GIA doesn’t have an ideal grade. The cut of A is superior which is why it reflects light back out, rather than straight thru like Diamond Bl. Did you watch the video?
What would the cost of diamond A be compared to diamond B?
Hi,
The Cut of the diamond can affect the price of the diamond significantly.
Feel free to email us at sales@jannpaul.com for more information :)
Diamond A cost your left nut, if you like diamond B it will be both your nuts please lmfao
fearsomefox23 is guess around 20-25 k
what are you talking about ,they are half carat stones, both of them would not get 20 k lol
Shopping for my bridal set and i have no idea what to look out for i know what I want but I definitely do not want to get ripped off to me A looks better
Getting what looks good and best to you is what truly matters so if you use that standard you can't be ripped off.
"A" was a better cut, therefore it looks better despite being 2 color grades lower. Cut is king.
Is tha what’s called bgm
I find it odd that you attributed all the dullness of diamond B to cut and not to the fact that is has medium fluorescence which of course will have an impact on how it appears in various lighting conditions. It clearly is hazy looking in sunlight and that’s likely due to the fluorescence that the D stone has while the F has no fluorescence. The difference in cut is also very minimal if you look at the diagrams on both certificates. That alone won’t produce the difference we see.
Yeah I don't understand. A is supposed to be better yet both are triple excellent with the only difference being diamond B is superior color but someone diamond A is supposed to be better?? 🤔
A has 7 black spear like things around the center. B doesn't What am I looking at?
Ones a hearts and arrows cut as the other is an ideal cut.
The diamond B clearly looks whiter compare to diamond A, i don't know what are you talking about.... I can instantly tell diamond B is the higher colored diamond before you reveal the info.
You came to the correct answer based on the wrong understanding of what 'color' means in a diamond. better color does not translate to whiteness btw
This isn't a good comparison. The D color diamond has feathers and clouds. Wasn't given a fair chance. 😂
Compare two of these with neither one of them having inclusions! 😊
A is the one that we should choose.
I want to sell
Scintillation matters.
0.3cart prize pls
Hi Jann Paul, so how could I know that there is light leakages, in case my eyes aren't trained to check out diamonds xD
Light leakage occurs when you have poorly cut diamonds. Follow the standard criteria (girdle, table percentage, depth percentage) for your shape of diamond and you’ll avoid light leakage. It looks like a dark spot with no sparkle
You have 50cart diamond I have byir
omg! i feel like I've got mugged by my jeweller!
Diamond A would be my choice. The other one is missing reflection. I want to look at my ring all day.
i have something you can look at all day and all night too lmfao
Bottom line.. no need to ever get over a F color.. or even H or G in most cases.
kmusic so ideal cut is whats going to give that “a” look on this vid with no light leakage etc?
How toidiendfy. Dimond. Ditacter
Easy just checking with HCA tool A has 0.9 score and B has 5.2. No brainer.
I got it wrong lol
Diamond A is better.
Diomond b playes better
B is real one
Oh, my God! I think the fire of diamond B is better
Not for being a boastful but I know it from the start.
After all of that I still don't know which diamond brings a higher price. How much more does B sell for over A, or is it the other way around.
I have an excellent cut E color diamond (.5 carat) and I knew B was the D color diamond. The explanation was good but if both diamonds are the same in all respects except color than the "light leakages" in diamond B should not have been there.
B has more colour
A 👍
F right.
Wtf
The reason Diamond A shines better is because it doesn’t have fluorescence. If the color of the diamond is in the I to L color, fluorescence will come in handy.
Not entirely. A is brighter and whiter due to excellent cut(true hearts and arrow) and with no light leakages compared to B.

This video is VERY, VERY MISLEADING! Unless one is grading a fancy colored diamond, i.e. pink, blue, or yellow, the stone is ALWAYS graded in the TABLE DOWN. position.
What causes light leakage?
badly cut shape, the light is refracted via total internal reflection. if the angle is too deep or shallow the light simply refracts out of the diamond, hence leakage.
poor cut by looks of it, diamond b is the better d GRADE BUT THE poor cut has gave it light leakage and should actually be cheaper
Both you idiot! All you had to do was read the description, and if you can't read, watch and listen to the video!!!
B was cut a bit too deep to hit the half carat benchmark
why annoying music?
I never noticed the music. Too focused on what he was saying.
To wear I would buy A, to invest I would buy B.
Diamonds are such a ripoff.
