Orange Fluorescence in (Pink!) Diamond

I stumbled upon this beautiful pink diamond on Leibish today, and noticed that it's listed as having orange fluorescence! https://www.leibish.com/pink-diamonds/fancy-pink-cushion-40625

I've never even heard of orange fluor, much less in such a big, gorgeous diamond. I ran a quick search on PS and I don't see much discussion on the topic. How much is the fluor contributing to the peachy color in this case? Really hope this stone went to a PSer so we can see more pictures! Meanwhile, my bucket list is getting longer...
 
It probably costs more than my car! But mmmmm it's so pretty and I want to drool over pics, so please tell me a PSer bought it!!
 
Crying in broke (pronounced baroque):cry2:
 
Here's a ( pretty poor) video showing orange fluorescence.
We've also seen pink diamonds that possess this shade of fluorescence.
In my experience, photos taken in the more sterile lighting environments tend to lessen the impact of fluorescence on the color in the photo

 
I have a small diamond that is phosphorescence. It glows blue under the blacklight but after you turn the light off it continues to glow light orange.
Such a cool effect.

That's a beautiful pink stone. It's reserved...you buying?:cheeky:

That video comes up as restricted on 2 browsers at work?

Works for me :P lol

(Not that that helps you ;) :lol: )


Orange Fluor is apparently quite (more) common in Laboratory Grown / Man Made Diamonds - it would be a flag of caution to me if this wasn't being sold by a reputable vendor.

Lol, yay you! I'll try it at home. Work computers block a lot of things. Luckily the diamond has a GIA report, as well as being sold by a reputable vendor.

Ok that's odd. I have 3 that have phosphorescence, and the only one that glows orange (sort of a yellow orange really) is my chameleon. The other two glow blue. And it is very cool. ;)
 
@Rockdiamond First off, love the new avatar pic! :wavey: Second, maybe it’s my eyes but I am not seeing orange fluorescence (or what my eyes perceive as orange) in the video you posted; the diamond still looks yellow to me under the black light. :confused:

PS: I so appreciate your posting a video to try and help us understand/learn! Thank you!
 
Thank you MOT!!!
I'll check through inventory to see if we have any other stones with Orange Fl and do a better video. In general many shades of fluorescence are so difficult to describe. For example- many stones with blue fluorescence almost look white in the dark under a UV. Yellow fluorescence is probably the most consistently colored in appearance under uv in the dark

It may just be my eyes not discerning the variation between yellow and orange fluorescence. I am - after all - picking up new eye glasses tomorrow. :mrgreen2:

I happened to discover that in addition to the center having MBF, one of the side diamonds in my ring also have fluorescence, and one appears (to me) to be yellow ... but very well could be called orange by GIA. I tried to capture it in pics:

Something tells me it might be a Type IIa, maybe just a hunch.

I'm not a diamond person but this made me perk up. I always through (or maybe have only seen) Type IIa diamonds to be clear, that is, non colored diamonds? is this a fallacy?

people be gentle, I'm a colored stoner...lol

@Rockdiamond Looking at that latest video you posted, I’m guessing mine has orange fluorescence as well. Tried to capture it in a video.
 
Cool videos!

And now I feel like an idiot lol. I had 'blue' stuck in my mind, because I usually look at the fluorescence and not the phosphorescence. I started to doubt my memory of the phosphorescence color last night. So at bedtime, I shined the uv light on them and what do you know - they were glowing yellowish orange and not blue at all!

I just noticed you were never answered..., Type IIa diamonds translate in a lack of nitrogen, e.g. nitrogen is the cause of yellow color being visualy noticed.
 
@Arcadian WWW

Any intensity of pink.

All the range of brown too from near colorless onward.

I do not know what the entire list of colours for Type IIa is. Count me curious.
 
GIA on red fluorescence...

Oh man! It’s been relisted for sale! A mere $111,200...where’s kenny? :P2

Guess what.....I heated the pink up this morning. Hot hot. It turned brown, then colorless, then within a millisecond of stopping heat, right back to pink. Is this normal
 
I ran a quick search on PS and I don't see much discussion on the topic.

There are two origines of pink color in a diamand.
A : Distortion of the lattice can give a pink collor.
B : Singular nitrogens with a lattice hole next to it also give a pink color.

De structure in B also gives an orange fluorecence. The structure in B is accomplished by irradiating a yellow type Ib diamond.

This irradiation can happen naturally, but normally it are artifically irradiated type 1b diamonds. (Both natural as labgrown type 1b diamonds).
