Pink diamond with Strong Blue Fluorescence - how come the color looks like this?

[Rockdiamond]

HI All!!
This is definitely a Lab Grown Diamond. The fluorescence pictured is considered Orange. LG Diamonds are treated to become pink.

As I just started carrying them a few months back, I'm hesitant to make blanket statements....but...every pink LG I've seen has Strong Orange Fluorescence.
Furthermore- I've seen numerous IGI reports calling it "Blue" fluorescence, in error.

I have a question......any idea why my intense green yellow diamond with strong green fluorescence would have fluor. orange when it was still in its little box? I'm sure it has to do
with the fluffy or spongy material, but I found it so weird - why would that stuff make it fluor. orange until I took it out of the box? Any ideas at all?

It would be irresponsible for me to make any substantive comment on a diamond I've not personally inspected.
I can add a few general points:
The actual color or fluorescence is extremely hard to pin down.
What's called "blue" sometimes looks ...white.
Part of this is due to the fact our eyes won't focus the same way on a stone being lit by a UV light.
Then, the sot of light used, and the environment under which it is used affects what we see.....

I guess I was really wondering if you had any thoughts on the packaging material and why it might affect the fluor. Because once I took the diamond out and checked the fluor., it was definitely green, like the GIA report said. I was more than a little worried until I took it out of the box, lol. Blurry, but this is the fluorescence out of the box:



Unfortunately I don't have a picture of the orange it showed while in the box.

Does a pink diamond with Strong Blue Fluorescence supposed to look like this?

I shone my UV light and it looks like a rosy pinkish/orangish glow? Where is the strong blue?

Could be the wavelengths emitted by your device, as others have said. But if the same device causes a blue florescent diamond in the normal color range to fluoresce blue, I would suspect an error of some kind on the report. Either it is not the same diamond as the report, or the color call on the fluorescence is incorrect.

You should be able to rule in or out a mismatch based on the other data on the report. If you are satisfied that it is the diamond in the report, then you could take it to a gemologist with a GIA fluorescence box and just have the fluoro verified.

As a lab grown diamond, it may or may not be important enough to go to a lot of trouble or expense.

Thanks for weighing in...most likely my IGI report is inaccurate!

@Demon I tried taking the pink in the conditions you have described. Turns out rosy orangey still.

thanks @Texas Leaguer ! This is not a high value purchase...so I do not think I will go through the additional expense to get the report rectified. I love the rosy orangey fluorescence actually.

I guess this is yet another example of what we see in the report may not be necessary accurate.

Makes me wonder, is this the reason why people prefer AGS or GIA reports over IGI reports? I think I have read somewhere that it is better to choose diamonds with AGS/GIA reports when it comes to mined diamonds.

Is there a chance the flour was called strong, without a color, and someone / some program assumed it was blue? I’ve seen this happen before. It looks super awesome btw.

My marquise is supposed to be faint blue flour (and GIA report says so), so I never played around with it much until the other day I realised that it's fluorescing white! Maybe yours is more white than blue?

Like @MiniMinerva said, lab pinks have orange fluor (inherited from the seed diamond), and I have to say that I haven't come across any pinks, orange or brown mined stones with blur fluor. Usually every other colour! My brownish pink mined stone fluoresces yellow/orange and another tiny pink stone is yellow.

I am not sure of the exact fluorescence color, the pink under UV looks more red/rosy than orangey at some point....but still, this pink rocks! Especially under strong sunlight! I loved it!

I have came across pink diamonds with blue fluorescence...even almost purchased one from Leibish. However, I am glad I did not in the end. It was a faint pink diamond with strong blue fluorescence and it will look like a colorless diamond, under most lighting conditions.

Wow if your marquise has white fluorescence, it will be extra bright and glows white under the sunlight! So cool!

It's actually got a nice glow. It's an F colour to boot

On the first point..... I can’t say for sure it’s incorrect.... but I do believe that the fluorescence is due to treatment done after manufacture.
On the second point- there’s many pink, and brown diamonds that fluoresce blue. Same for orange tinted stones. ( Pure orange is so rare it’s not possible to make blanket statements)

min terms of “blue” fluorescence..... the blue could easily be mistaken for white.

Let me put it this way to many trade people they could have a diamond in front of them that looks pink, has natural looking inclusions and is diamond.
But it is not a natural pink until GIA says it is.
Not even AGS would be accepted as good as they are with diamonds of lesser tint.
If a GIA report could add thousands of dollars to the value of a mined colored diamond and even sometimes 10x it, why would they send it some place else?

And even redder! Weird. Now I've got to check a merlani mint garnet I have - it fluoresces
red/orange in its box......I'll have t find out if it does out of the box....

This is one of the interesting differences I've noticed...I would never accept an IGI report on face value for an Earth Mined Diamond.....and as I've noted, I find IGI to be less than.....perfect on Lab Growns- but it doesn't seem to matter as much.

It glows that way because of the treatment to make the lab diamond pink.

I believe several of the commenters were assuming this was a mined diamond because it was posted in Rocky Talky and you did not originally post the report or specify that it was lab. They were responding to you as if it were a mined diamond.

Most likely it's your UV lamp/light.

The labs grade fluorescence at specific wavelengths - if your light doesn't match those wavelengths, your stone might well not exhibit the behaviour specified on the report. Most cheap UV lights don't emit the wavelength they claim to.

Agree on this. I had a side stone with FL in an old setting, marked blue but under the UV lights at the nail salon, for drying gel polish, it was an errie Yellowish Green.
