It is about time someone talks about this
Wow thanks! I just got my diamond and when I came home and saw the GIA report I got scared seeing it said very strong blue but after this video I prefer the very strong blue ones!! Yay!
We're glad the video was helpful : )
Beautiful daylight fluorescence too !!
Fantastic video! Very informative! Well done Jon!
So happy that I found your channel & now subcribe. You make everything so clear & understandable.
Thank you for your video. It explains the change from red without light and blue with fluorescent light
You _laugh_ a lot in your videos! You must like your job, and that's nice to see!
Thanks for this great info on diamond fluorescence.
I absolutely love fluorescence in diamonds - especially the old cut diamonds which have a blue hue to them. Just my own preference, I suppose.
I looked this up because I noticed that one of the diamonds in my ring glows when my nails are under the UV light at the nail salon 😂. Very informative video. I like the stones in this video with the high florescence better 🙂
Same lol
HAH ME TOO lol that is exactly why I searched this!

Great info for people, thanks.
Terrific!!! and sincerely helpful.
Very informative. Thank you!
i love your presentation.......ty.
Thanks, I always wanted to know about this!
What I learned from this video is that when seeing the side by side comparison of the diamonds without fluorescence and with fluorescence is that fluorescence makes the diamond look more milky it reduces the transparency even in natural daylight. That helps me decide that I should go with the diamond with either faint or no fluorescence because I want my diamond to be more transparent and sparkly. Thanks for the video it was helpful. 👍
You're welcome. We glad the video was helpful!

The strong blue fluorescence looks really exciting
Yes, it's a cool natural phenomena!
Thank you so much for this valuable information. We learned a lot from you. Thanks
great video ,thx for sharing this info
Fluoresce makes the rock looks a hue more white, and it’s usually more clear. Also diamond lighting up looks amazing.
Yes, it often does! Especially in diamonds that are slightly off color.
Very informative, thank you. 👍
When I seen some of my diamonds glowing under a black light at a club party I got upset thinking the diamonds glowing were fake. So I had to look this up. Thanks for the info.
We're glad that we were able to offer you some peace of mind ; )
This is a great video! Now I know what fluorescent means, and how it really looks like under different lightings.
phosphorescent red "Hope" diamond is neat...This is a significant form of a educational documentary video. I appreciate the effective use of comparisons with your time and care shared. Excellent smiles with your dazzlingly informative scintillating show.☺

Cool info., My wedding ring's center diamond is very flourescent, light blue under a black light and it is E color. Very beautiful. I love it!
Very nice presentation & good information.
Thank you sir.
Great vid, detailed info!
Thanks : )
I love it. I look and find raw diamond stones i have aquierd an eye for finding them i love it
GOOD INFORMATION SIR 👍
Thanks. We're glad the video was helpful!
you are good!!!
Great video! I have a fancy white opalescent 3crt diamond that fluoresces very strong blue and phosphoresces after. Love this stone lookes purple in the later stage and holds for quite some time.Also have a fancy canary yellow rose cut 4crt that fluoresces to yellow medium that is amazingly bright and sparkly with no phosphorescence at all. So fun!
+Jenna Flesch Wowza. Yea ... finding them with phosphorescence is like finding a needle in a haystack! Good find.
Great video, I’ve been collecting diamonds for a while and have blue, red, orange, yellow, and green fluorescent ones. Looking for phosflourescent diamonds is way harder but I’ll get one eventually
You must have an impressive collection that you've gained over the years! Best of luck with your continued search. Although very rare, when we do come across diamonds that are phosphorescent, the feeling is exciting and reminds us of when we found 4 leaf clovers as children.
Awesome video man. I just might subscribe.
Thanks, we3're glad the video was of assistance!
..... I like your background... It looks like Minecraft diamonds...
Interesting video btw
Thank you. Sir
You're welcome. Glad the video was of assistance!
16:10 I believe actually there's a bit more fire in the one on the right from what I see.
good info! had no clue they flores red, green, yellow!
I just found out about this fluorescent stuff I bought a jewelers loop that had a fluorescent light on it, of course I didn’t know that but I’m glad it did now so I have a 1 carat diamond ring with the center diamond being .67 the rest of the standard small round stones surrounding it out of the whole freaking ring only three small stone Fluoresce , omg
You have a good crisp voice for videos.
Thank you kindly Zuko LeadsTheWay .

Thanks Good old gold, great video, one question though:
So it's the presence of Boron which can give a diamond fluorescence. But do you know what is it that determines the colour of the fluorescence??
Thanks :)
Great one!! Thx very much for sharing such important information !!
I'm looking at a 1.5ct G colour SI2(eye clean) diamond. Everything seems alright but the fluorescence is strong yellow...
Mentioned in the video, blue fluorescence may make it looks whiter. Would yellow fluorescence makes it look more yellowish? Like colour downgrading instead of upgrading if it's blue fluorescence?
Any other comments?
Thanks a lot!!!
Boris lo Hi Boris. Yes sir. I do in fact avoid yellow fluorescence. The only pro is that it dramatically reduces price but ... at a cost. (no pun intended). ;) If you would like our assistance in helping you hunt down an eye clean SI2 with fluoro that will enhance the color drop us an email via our contact page.

Thanks, we're glad the video was helpful!
Good channel. I checked out your website .Unfortunately for me , the lowest price filter is over my budget .
If you go on our search, leave it as is and sort by price the least expensive diamond is $400. is that over your budget?
I love your videos. Although this video is old now, I should probably mention that glass blocks most UV. You can't really show fluorescence in sunlight from behind a window... If you ever remake this video it'd be nice if all the natural light demos were outside or in front of an open window.
Thanks for the tip Jeff Kriske
Not true. Ordinary window glass passes both UV and IR light, which is why art galleries use special UV blocking glass in framed art.
You can also go to any optician and look at sunglasses. Unless they have a special coating, the tag will not claim any UV resistance.
Oddly enough most plastics block UV very well and most are coated to block UV and IR. Genuine gold flashing also blocks IR almost totally, which is why it is used in glacier glasses.
If you have Varilux Transitions lenses, they use the UV light to make a chemical change which darkens them and blocks most UV in sunlight.
In a car you will find this reaction is weaker because the TINTED glass blocks some but not all UV.
@@lyfandeth Ordinary window glass blocks UVB and some UVA, glass also reflects IR, while short wave IR can pass through glass mid and long wave IR cannot. This is why thermal cameras use special optics. So yes, why you might need a special material to block it all, please don't be under the misconception that it doesn't block UV or IR.

Your welcome. We're able we are able to be of assistance : )
Awesome presentation, very nice, more importantly you informed me with a lot of information. I know this is just the basics, wow, lol.
I also like the guitar music, do you know who is playing.
Thank You
Thank you kindly Fermata Notes. Not sure who the guitarist is though. :)
Yes this is nice work
Of course gia would say that
So would this work for trying to find rough diamonds in nature? I want to get out to the diamond rich ancient volcanic crater in Arkansas. I'm thinking if I go I could use a large cardboard box to filter out the daylight and use a blacklight on the inside as means of finding them.
SupermarketSweep777 Not sure how many you'll find but yes ... I would imagine UV to be some kind of help but I'm not sure how practical it will be. You may want to google "sifting for diamonds" and see what you come up with. ;)
Good Old Gold I will. Thank you for the response. :) I checked some hunting tips, and it's pretty much like gold hunting. A lot of digging and sifting.
Fun to learn even though I’ll probably never buy a diamond.
At 17:32 the F looks yellow and the I looks White...amazing.
Joe B I know right!?!?!
What kind of lighting do you use? The view far away is better for me to notice the difference.
To expose the level of fluorescence, we use a black and/or ultraviolet light
Just bought an E color GIA diamond. With no idea of what Fluorescence is. (None Fluorescence certified). After done purchase went back home. while stopped at traffic light, take a look at the stone (under daylight) and looked a really clear blue. was hesitated a while (wondering they switched the mounted diamond.) The whole stone change color into a really beautiful clear blue (almost like a strong fluorescence). definitely. later studied a bit about it and found out. Is it possible that GIA miss-measured the stone fluorescence?
Try buying a UV flashlight off amazon and testing it out in the dark. They cost like, $10-15. My fiance's one diamond earring didn't show any reaction at all whereas the other has an obvious blue fluorescence. Her engagement ring also has medium fluorescence (GIA graded) and it lit up like crazy. I doubt that GIA would get the fluorescence level that wrong (from none to strong) - the effect of fluorescent lighting in sunlight would pale in comparison to holding the diamond loose, face down, under a lamp. Also you should verify the GIA inscription if you're worried about the diamond being switched out.
Hola, Jonathan!
Agradecería mucho su opinión en la elección de un anillo.
Cuál cree que es mejor opción, un E VS1 3EXCELLENT FAINT o un E
VS2 3EXCELLENT NONE?
Gracias!!
Hi, I'd need additional information in order to make a more informed decision. But from an investment standpoint and based off the limited information provided, I'd say perhaps go for the VS1?
Muchas gracias por tu respuesta! Para mi es suficiente su información. Estoy muy agradecida.
Un saludo!
The nerd part of me wants the extremely fluorescent ones
hello do u have documents to read more information about diamonds. ı doing this job at turkey and ı want improve myself. also ı watching your videos they are very good. thank you
We used to have a ton of diamond information on our older website and we plan to add some useful information to our current website in the future. However in the meantime if you browser the internet, you should be able to find almost everything you'll need to know about diamonds.
Does different levels of fluorescence look differently in an idealscope/ASET? Would a hazy fluorescence one show up any differently?
no
Patricia is correct
Join sher lubuk sri lanka aku friend sana senyap lurr..pancing
This is not a valid assessment of phosphorescence. You would need to put the diamonds in a completely dark environment to observe this effect. Aside from that issue, very informative video!
That's correct Eric. Wasn't meant to be an assessment of phosphorescence at all. I just made mention of it because it does exist in some diamonds with fluorescence. Trying to find diamonds with phosphorescence is like finding a needle in a haystack.
So I just bought an engagement ring and the diamond is colour grade D clarity vs2, fluorescence none, I'm sure it will still sparkle for her... I hope :-)
How many carats bro? I am finding it hard to choose one. I want to go for Colour - D or E, Clarity grade - Internal Flawless with as less weight as 0.30 Carats. I think the size is not too bad while the quality is premium. Or I can go for a bigger size (1 carats) under VS1 or VS2 with a colour not weaker than G.
SyKo SyKomatik I got a 0.3 carat. It is small but if the cut and color is good then the diamond still very beautiful
SyKo SyKomatik sorry to butt in but you don’t have to get a D internally flawless. You can get a beautiful diamond in the F/G/H-VS2/SI1 range. If you’re willing to buy online, check out Lauren B on Instagram, they are no bs type of jeweler.
@@theoriginalbearbear make sure you have a GIA certificate.
@The Original BearBear make sure you have a GIA certificate.
Interesting. Can other gemstones also have phosphorescence?
Absolutely Glacier.
But zirconia doesn’t right?
I was just recently at the nail salon and some of my diamonds in my small channel set were glowing very bright maybe four or five out of the whole channels
Thanks for sharing that. It's not uncommon for jewelers to mix and match diamonds that have different levels of fluorescence in rings because unless the ring is being placed under a black light, you'd probably never know there were any differences in their fluorescence level.
how can you tell if they are milky/oily if you're buying online or even in stores if you can't see it in sunlight?
That's a good question. I believe it's one of the risks in buying a diamond online. Unless the retailer can prove to you that the stone is not milky (like we do using our high definition video technologies), you can cross your fingers and hope for the best. Sometimes you might be able to ask the retailer if the diamond is milky and they might be able to provide you with that information verbally.
It doesn’t need to be in sunlight. If it’s not milky in normal indoor light, then it won’t fundamentally turn milky in UV/sunlight. However, the literal fluorescence of the diamond can look milky, but that’s only when it fluoresces, at which time the blue will be taking over anyways and it will simply look blue. Then when that UV goes away it will be clear
This was amazing I've learned so much! I'm doing a bit of research on this - being from Australia it's just easier to get diamonds from and Australian provider and cheaper due to customs and import tax....just looking for advice - I wanted to get a 1.5-1.8ct RB I'm thinking H color SI1 but because I want it face up nice and white I wanted to get a beautifully cut diamond with fluorescence but you said in many cases it doesn't impact the diamond...how do I know as a buyer that it will make the diamond appear "whiter" than a DEF without asking the provider to let me leave the store and look at it in the sunlight ? Lol not sure they'd be too happy
missnars87 Greetings and yes you're right. Jewelry stores will generally not allow you to view diamonds outside. There are 2 aspects that will make a diamond appear whiter which you mentioned. Cut quality and fluoro combined is a nice recipe in H-J colors. If you have already decided you're going to get your diamond there in Oz I'd say take the chance with a strong fluoro (min medium fluoro) diamond that is cut along the guidlines of our Superior or at the very least Premium guidelines on our site. The premiums we hand pick will have guaranteed optics in the GIA EX/AGS Ideal zenith with good looking ASET results. You may get a great discount due to the fluoro too. ;)
Good Old Gold Thank you so much for your quick reply! Can you just fly here so i can take you along my diamond hunt? ahaha. I have viewed almost every video you've loaded, the website, pricescope...at the end of the day I think the biggest struggle is as a consumer, being able to actually use all this information without having someone like you right there to guide them. I think what I struggle most with is trying to find the right combo of numbers without having to buy a branded H&A. It seems almost impossible. Hopefully I'll keep learning and pick up some new tips along the way. Thanks all the way OZ! :D

Terima kasih, Saya lebih suka berlian fluorescence none❤.
Terima kasih guru sudah berbagi ilmu.
20:03 the 0.95ct round looks bigger than the 1.14 ct cushion
Because of the cut the left one is cushion the right one is round and also the pen holder is bigger that’s why I give the diamond more edges
what if i have ring with lightpink heart stone. and if i light it with UV light it frorescents green what kind of stone is that
Interesting.. There is a chance it's a diamond. Diamonds can be light pink in color and although most diamonds with fluorescence usually show blue, we've came across diamonds that show green, yellow, orange, and other colors of fluorescence. If you go to your local jewelry store, they should have a diamond tester and if it's not a diamond, an appraiser or gemologist should be able to determine what type of stone it is.
Belum kaabah punya lagi militry aku celup kang
I like at 13:32.
any quick video how to determine fake from real diamond?
That's a good question Mahasajan. We never made a video like that to my knowledge because we just use technological equipment (diamond testers) to determine if a diamond is real or a CZ (cubic zirconia). We do the same to distinguish diamonds from other gemstones such as moissanites. It's also how we determine earth grown from lab grown diamonds.
The equipment can be pretty expensive and for businesses like us who buy diamonds on a weekly basis, it's worth it. To the general public however, a trusted local jewelry store, a trusted appraiser, or sending the stone to a reputable lab like GIA would probably be your best best to determine if a stone is a real diamond or not from a cost standpoint.
CZ's can often be viewed under a microscope to notice that it's not a real diamond. But other gemstones can look the same (even under a microscope) which is why we have invested in the equipment I mentioned above.
If the weight of a stone does not correlate with the stone's measurements, it can also be used to to separate the pretenders.
I thought the song were jacob sartorious - sweatshirt lol

Thanks I never really appreciated florescence.
There is a reason background music is called this. Only here it's so much in the foreground it's almost impossible to hear what the presenter is saying, it just totally distracted me from what would be a great information video.
I appreciate the input. I'll redo this without the background sound.
Lin Joy I agree with you, it sucks mind...
Lin Joy didn't get to me at all
Lin Joy ......dident notice now i can’t hear him? 👂
The music went well with the info. You proly have hearing issues along with a shrewd always right perspective on things. Just focus and enjoy. Its information that can be viewed multiple times thus its a UA-cam video.

Who’s carrying around an ultraviolet light and a loupe to examine your diamond when you’re wearing it? Raise your hand!
The Original BearBear ..... good point
Are they worth anything?
Fluorescence can affect the value of a diamond and more often than not, a grade of medium or higher, usually slightly decreases their value.
Too much music, interesting information though
the music was great
Not everyone like fluorescent because of the environment not every time you will be outdoors example of mismatching gets result
D-f needs none
G-I maybe none to medium
J-p expect to have medium to very strong
If it's just boron being present that causes fluorescence, what would cause variation of color;. I.e. the 7-8 other colors this gentleman mentioned. I'd imagine there's chromium, vanadium, calcium, uranyl ions etc. That are probably dopants in the diamond structure. Also, I have to watch this on closed captioning... this is an aggressively new Jersey accent that I.... well, I just can't. It hurts my soul.
Haha, good guess! We're based out of Long Island which is super close to Jersey.
Regarding diamond color variations - diamonds occur in a variety of colors-steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. Colored diamonds contain interstitial impurities or structural defects that cause the coloration.
I thought 365nm UV was the standard.
Yes, I believe 365nm UV is the standard. But anything close to that should work for the visual propose of this presentation.
@@DiamondInfoMan 👍😁
My Diamonds turn pink and some purple under black light. What does that mean? Fake?
Hey Tonya, I believe that is an example of those diamonds having fluorescence. In the below link, you should see a photo of some of the colors that can be exposed when diamonds with fluorescence are placed under a black light. www.google.com/search?q=pink+fluorescence+diamonds&newwindow=1&tbm=isch&source=iu&ictx=1&fir=HXW1S0Z11TE6eM%253A%252CvggwCkpBuyR-ZM%252C_&usg=AI4_-kSTKe-hqXj3_pLSEH-s50-nbaYYSw&sa=X&ved=2ahUKEwi5_u_8n7bfAhXuct8KHcdTA_sQ9QEwEXoECAQQBg#imgrc=HXW1S0Z11TE6eM:
Also, if you believe their is a chance that the diamonds might be fake, you might want to go to your local jeweler to have them test the diamonds to see if they are real or not. I don't see pink fluorescence very often, so it something that I would recommend looking into.
@@DiamondInfoMan19:22
My rubies are wonderfully fluorescent, like they should be.
Really, what color is the flourescence?
15:30
This sounds like the information a jeweler who might try to sell a slightly hazy stone to a customer would say . Your example is not an average example, but rather an extreme one. The truth is since there are examples of Florescence having no impact on clarity it can not be used as a determining factor . However if a stone has a strong fluorescence it would be a good idea to examine the clarity of the stone in various lighting conditions as there is a correlation to stones with fluorescence having some degree of haze or clouding that may not be obvious to the consumer or anyone for that matter until the right conditions in lighting cause certain wavelengths in light to reflect and make the stone appear hazy .
Hey Kef103. You are correct.. It's definitely recommended that a diamond with fluorescence go though the proper screening before the purchase is final because about 2% of diamonds with fluorescence can indeed have that hazy appearance under certain lighting conditions as you mentioned.
Just to say, a customer should examine a diamond under different lighting conditions no matter what! It's just common sense. Jewelry store lighting makes diamonds sparkle to the max, on purpose, so every diamond needs to be examined under several different lighting conditions because they'll all have a different effect on the appearance of the stone.
Hurry up with my noodles,
damn it I'm very interested in the subject and your knowledge but that background music that's so loud it seems like your having to talk over it has ruined the video. I would suggest maybe in the into but once the info portion has begun it more then not needed its pointless, distracting, and takes away from the quality. I've had to mute It and turn on CC just to get the info I require which is a huge fail on your part. please plz plz remember the KISS rule.it goes a long way especially in sales. btw great info otherwise
I agree and appreciate your feedback. It was an older video and since then, we've eliminated that annoying background music.
I love the music! And I’m quite minimalist. It really gave character.
The point here is the price. Whether the fluorescence is a negative or not but perceived as such I expect a hefty discount. I want a heavy blue fluorescent diamond but I expect a massive discount thanks. I’m not being conned by a dealer trying to put a spin on something unpalatable to consumers rightly or wrongly.
GIA uses 365nm not 400nm… Why are you using 400nm???
The tool we purchased years ago is 400nm. But when it's time to reinvest in a similar tool, we'll get one with 365nm in an effort to be more in-line with GIA. We appreciate you brining this to our attention as we didn't consider this in the past.
The music in the beginning is awful....wearing headphones yeah I don’t need my ears at all 🙄
Turn down your music
We agree. We have eliminated the music in the newer video's as it became an unnecessary distraction.
Nobody profits from buying a diamond bud. Go to sell it after purchase and you will lose half of your very poor investment immediately. No profit at all when that happens.
Why so much fussing about these stones. Just give me a big fat stone of any fluorescence lol😂
Lol
OMGoodness...It was so difficult to watch this...that music was sooo...annoying. Why couldn't you just present the facts w/o it?
Cool video but the mic is completely unnecessary for a UA-cam video. If you insist on holding something up to your face hole I'd go with one of those tiny mic's like the one Bob Barker always used on the Price is Right.Unless it's your life goal is to be the one upper on ol' Bob there which I had previously pointed out had a cooler mic than the clunker you gots...🤔🤗😎
