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

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

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

Sorry, I can't help. I just wanted to say it looks really pretty.
 
This may be a silly question, but is it against the white material that they're packaged in? A diamond of mine that has strong green fluorescence looked like the fluor. was orange until I removed it from its little box.
 
Could it be the wavelength of your UV light?
 
I have no idea, bu: Oh! So cool!

Hi no.. This is taken in a completely dark room.. Out of its box

I’ve no idea but I think it’s way cooler that it’s glowing pink

I didn't expect that it will look rosy purplish.. Sometimes looks orangey too.

Now I know why it looks more rosey in the sunlight.

And so not laying on the white fluffy or spongy stuff from the box.....then I have no idea why! Maybe @Garry H (Cut Nut) would have an idea?

Yes yes. This looks legit... Does it mean my diamond has been graded wrongly by IGI?
 
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.

The igi report states strong blue.. Now wonder i why there is a disparity with the IGI report n the 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.

Thanks! Does the color of the diamond makes a difference?

When the same UV light is used on my colorless diamond.. It Is glowing blue. But when used on this pink diamond.. It is glowing another color. What a mystery!!
 
I wish I could be further help, but am watching this thread hoping you get info to ease your mind. Can we see the drain regular light? Does the dimensions match the report?
 
Hi yes, the serial number matches the report.

Some photos here indoors:





Under sunlight:




I have tried to contact IGI through the enquiry form: but the form seem to be stuck. i.e. it is showing the same screen even after I have submitted the form.

Wow this is a first for me...:doh:

What color does the report say?
And any other notations?

Very pretty!

The report says strong blue and nothing else.....but turns out like this. :confused: What a pleasant surprise...

But then I am very worried now since the IGI report is different from the properties of the actual diamond...

paging for @kenny for some advice...
 
I meant to ask color description of the pink.
 
Not sure this was already asked, but is it natural earth mined diamond with natural color, or is it a lab diamond and/or irradiated color? It should say on the IGI report.
 
Maybe that lab only has default for blue?

Maybe @Rockdiamond can also give a general opinion on the colored fluorescence you see.

Oh its a lab diamond. Does this offer any insights as to why I am seeing a different color fluorescence from the report?

Report as follows

I read somewhere that lab diamonds can fluoresce in different colors than natural diamonds. Also, they are more likely to phosphoresce - which means they still glow in the dark (sometimes a different color) after you remove the UV light source.

I can’t find the explanation of why this is, but that’s why I was curious whether it was a lab grown diamond. As for the Blue vs. your color, as other posters explained, that might have to do with whether your UV light source is long- or short-wave. I don’t know the difference, I just use my gel nail light for doing diamond tricks :)

The white stone might fluoresce blue at varying wavelengths :))

Not saying that it is your light, just that that is IMO the most likely reason.

Fluorescence seems challenging for the labs to pin down, even in colourless diamonds. These are my own stones (photo taken by a vendor several years ago):

All stones have GIA reports. The largest pair of sidestones: One has "faint" fluor by their GIA report, the other has "none".
The middle pair of sidestones: Both have "none" per their GIA reports.

Edit - I just read more and see this is a lab stone.

My understanding is the same as @ringo865 - I believe lab stones can behave quite differently with regard to fluorescence. There’s a forum dedicated to lab grown stones (MMD) - you might find more expertise if you ask there!
 
I was going to say it looks treated, but since it is lab grown, it sort of is treated (the color is produced). It is a very pretty stone!
