Red Fluorescence

[davi_el_mejor]

My newest FCD has red fluor. Unfortunately the diamond is a greenish color so the fluor doesn't enhance the color.

All the searching I've done says red fluor is rare. My seaching also says that chemical vapor deposition diamonds fluor red. What do you think is more likely, a natural diamond with red fluor or finding a faceted greenish chemical vapor deposition diamond?

Stats and pics:

.25ct pear




and the fluor


Is this another one I should send to GIA to double check?

Mmmmmmmm.
Love it.

The Hope fluoresces red, or is it orange-red?

Davi, if you move to a planet with only UV light you just got yourself RED DIAMOND!!!!!!!!!!!!!!

You Da FCD MAN!!!!!!!!!!

Thanks Kenny, but I still cower in the presence of your collection. Yes the Hope has red fluor and it is also phosphorescent. Mine doesn't phosph The only interesting thing about it is its red fluor. I think the fluor doesn't add to the color, but it does lighten the stone up. It's dark under incandescent light, but in sunshine it mellows out the saturation and is a much more lively stone.

I don't think I'll be sending this one to GIA. My first one should be back shortly and we'll see how accurate the vendors description is. I miss having all my little lovelies at home. One's at school, one's getting some "dental work" done (aka a face lift) and this little guy is sitting here in a plastic baggy waiting for a photo shoot.

Help, what is a phosphorescent diamond? When I saw the Hope IRL, I thought I just saw blue fluorescence?

The Hope is a blue diamond, when exposed to UV light, the stone emits a red fluorescence. Phosphorescence is when the stone continues to glow after exposure to UV lighting. UV light is present in sunlight, fluorescent light and minimally in incandescent light.

davi -- that red is fantastic! What a sweet stone, like a drop of honey. I have to stay out of these threads for fear I will develop an expensive FCD habit!

Cool stone davi!

The Hope and The Wittelsbach-Graff both phosphoresce intense orange-red after exposure to shortwave uv, but they don't exhibit fluorescence during exposure to either short wave or long wave uv-just tweaked the fluorescence tutorial to make that clearer. There is a great article in Gems and Gemology Summer 2010-The Wittelsbach Graff and Hope Diamonds: Not Cut from the Same Rough

Now that is interesting Coati! Thanks!

Cool, thanks for the info. I'm going to nip down to the Smithsonian sometime soon and see if I can see the red. There were too many people last time and I think I was seeing a different kind of red, if you know what I mean!

Hi.

As I also has seen online - RED fluorescence is very very rare, you can read about it here;
http://www.fancydiamonds.net/diamond_education/articles/how_chameleon_diamonds_change_color.htm
It's stated there about RED fluorescence in general!

I actually bought a 2.11 carat Chameleon and a 3.10 carat Chameleon diamond.
As I were checking the Ruby's for fluorescene (approx. 7 hours ago) I just wanted to test the Chameleon's as well.
Both diamonds turned out with an "flamable red" color!
I've never ever seen this before and I got about 50 diamonds in my collection.

I also made a video, showing the red fluorescence...
But is not allowed to post it here tho'..

That red is so cool!!!
