    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...

    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

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

    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:

    Works for me :razz: 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.

    @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:

    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

    Fresh attempt- which contradicts what I wrote earlier about yellow fluorescence.

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

    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!
