Red Fluorescence

[platestealer]

I recently came across a colorless .8ct round diamond, and it actually fluoresces medium red. I have been trying to find out how this affects the price of a diamond, but all I can find is that red fluorescence on a diamond is rare or even very rare. Any thoughts?

 

[Niel]

Oh my gosh I can't say what'll it'll do to the look. But I'd get it home and see!

I am a nerd for fluor and I LOVE a stone with red fluor.

Is it a well cut stone?

 

[platestealer]

it's an ideal and it is a very nicely cut diamond, nice sparkle

Have you seen it in person? Are you able to

 

[platestealer]

I haven't seen it yet in person, but I am able to. I am just trying to figure out how the red fluorescence affects the value assuming it doesn't detract from quality of the diamond

 

[Niel]

Well I know fluor in general does effect the price. And I know colors like yellow are less desirable for white diamonds, though I have not seen too much about the effect on price specifically.

hi platstealer,
Welcome to Pricescope!
How did you determine the diamond has red fluorescence?

From the GIA report...fluorescence says medium red

 

[Rockdiamond]

That's the first time I've ever heard of that....remarkable.
Can you please post a copy of the GIA - or the GIA report number...
Not to sound overly skeptical, but it will be interesting to see.
Searching the worldwide database of over 6 billion dollars worth of non treated diamonds yields zero results with any sort of red fluorescence.

I wonder if it might look slightly pink-ish in sunlight, like those with blue flourescence look blue-ish? It sounds awesome!

Right. Sounds amazing. Just the idea of it being that rare I'd be all over it. Medium should effect the color in sunlight that much right? I know some BGBs are medium, but usually strong.


I wish it was mine.

Once I figure out if I am going to get it, I will share the report. It is a nicely cut diamond (scored a 1.3 on the calculator). I did just buy a different diamond, but found this one last night and honestly says "Fluorescence: medium red". It is priced about 10% higher (~4 grand). Just trying to figure out if it is something that is worth the hassle of returning the other one and getting this one. It does sound like they are very rare.

Sounds like the consensus is to get it

 

[Rockdiamond]

There was one stone in the database listed as "Very Strong, Red" fluorescence- however I clicked through the to report and it was actually Strong Yellow

I'd be very interested to see the actual report once you share it.

 

[platestealer]

What is peoples thoughts on it? Will the red negatively affect the color of the diamond and does the red fluorescence increase the value (is it worth spending 4k on it for a colorless, ideal cut ~.8ct diamond)

 

[Rockdiamond]

Platestealer, in all likelihood, there's an error someplace.
Whatever opinion might be put forth will have no basis in actual experience since Red Fluorescence in diamonds is completely unheard of.
Unfortunately, GIA does occasionally make an error on fluorescence- and till we see an actual GIA report, I'd be skeptical of even that happening.

right. Never heard of it. Would love to see the report.

Doesn't the hope diamond have red fluor? Or is that the phosphorescence.

 

[arkieb1]

I think that would be totally cool, if you can arrange it, go and look at it!!!! If you do, look at it inside under shop lighting and if they let you please take it out into the sunlight. See if it goes milky or dull at all, and if it has a feint pink tint or tone in the sun in any way.

 

[Rockdiamond]

Good point neil!
That would be red phosphorescence- different than Fluorescence.
So, we're thinking this might be a little chunk of the Hope diamond - which also happens to be blue?

There's been many cases of people being led to believe a GIA report exists, when there's something other than a GIA report.
All due respect platestealer- if you've seen the report with your own eyes, who can argue with that.
Maybe this is the only diamond in the world with red fluorescence- does it sound plausible to you?

This is why people are asking to see the report firsthand.

 

[platestealer]

Rockdiamond-

I have checked the report multiple times on GIA.edu and from the dealer and all the reports say the same thing....medium red. I understand that there may be a mistake but getting the color of the fluorescence wrong would not be one of the more "common" mistakes made in these GIA reports. Regarding the fact that it is unheard of, everything I have read says that red fluorescence is possible, but very rare. I am thinking of getting it sent to me to inspect myself and if worse comes to worse, I send it back. I realize that it may not be what I think it may be and if that is the case, I can have it sent back, but I think having the loose diamond sent to me is worth it so I can see it with my own eyes (minimal downside)

 

[JulieN]

I would love a red fluoro!

OP you just need to post the GIA number and carat weight so we can all see for ourselves.

 

[Rockdiamond]

There is minimal downside- so why not!

I am curious about where you've read that Red Fluorescence is possible but rare.....this is due to my interest as my life is so heavily wrapped up in diamonds, so I am genuinely interested.

Stranger things have for sure happened.....
I've seen Orange Fluorescence....

BTW- I have experienced GIA making a mistake on fluorescence, on multiple occasions.

Now of course, its not all that reputable. But Google it and you do get results.

Red fluorescence is extremely rare in natural diamonds.

There is a lab-grown process (CVD)that creates stones with red fluorescence, but they don't usually grow big enough to produce an ideal cut .80ct round. http://en.wikipedia.org/wiki/Chemical_vapor_deposition

JCK has an article on it here: http://www.jckonline.com/article/284220-Identifying_CVD_Synthetic_Diamond.php

Great stuff Davi!!

AS I mentioned, I have seen Orange Fluorescence, which happened to be in a Brown Pink.
But never seen GIA identify Red- the article did mention "weak red"- but also mentioned such fl occurred on brownish pink stones-.
I'm sure we're all anxious to see the GIA report and the stone in question.

 

[kenny]

I have a diamond with what I'd call hot pink fluorescence, most unusual.
The GIA report for this fully natural Orangy-Pink diamond is the abbreviated report that does not mention florescence.
The vendor, Leibish, didn't know it florescent, let alone this color.



It's in the upper-right corner of these pics.

 

[Rockdiamond]

Super cool Kenny!!!

This is actually the best photo of the stone we had with Medium Orange Fluorescence.
It was years ago.....

Let's remember that the OP mentioned a colorless diamond- every scrap of info we have seen so far has not mentioned a colorless stone when referring to anything to do with Red Fluorescence.

Really will be cool to see this report......and to see if such a diamond with red fl actually exists.....

 

[leoshraeder]

A red fluorescence in a white diamond? Get pictures of it!

 

[RockyRacoon]

Any update here?

Inquiring minds want to know!
