I encountered a blue diamond at an auction last month...I was interested in it and under supervision, I was allowed to take some pictures of it under daylight, indoor light and used a black light as well. It glows multiple colors...orange, deep indigo blue, pink, faint yellow, and white. My camera could not take a good picture of the intense orange but I was able to catch the faint yellow. Is this a good thing for a blue diamond to glow multiple colors under black light? It also turned completely white and transparently clear like ice under daylight(causing the facets to disappear and the area to look like clear ice). Thanks!
 
i''ve never heard of a diamond fluorescing multiple colours

Sounds suspicious.
Good thing you didn''t buy it.

Can you post your pics?
 
The stone blasted with brilliance. However, I''m not familiar also with diamond glowing multiply colors under black light. Sorry, I''m unable to display photos due to third party agreement/only buyer. Thanks!
 
Is it possible there were other light sources besides the black light?
Small pointed light sources, like halogens or spotlights in the ceiling, may explain those other colors if they were flashes of colored light.

Or are you saying that one moment the entire diamond glowed one color of blue, then a moment later the entire diamond glowed one shade of yellow, then a moment later it somehow turned all pink, and so on?

Also you wrote, "...turned completely white and transparently clear like ice under daylight".
That would mean it is not a blue diamond.
Blue diamonds look blue in daylight.

Edit: I would never buy a colored diamond unless it was graded by GIA. PERIOD!
It's too easy to get ripped off.
Real blue diamonds with color of natural origin are very expensive and anyone selling something they are calling a blue diamond without a legit lab report raises a red flag with the word RUN on it.

Now THIS sounds suspicious. Get the seller to have it independently appraised (and you choose the appraiser) before any sort of purchasing agreement.
 
No need to appraise it... the auction end/ perhaps, already purchased...Thanks!

Third party agreement??? You took the photos. The photos belong to you with all rights.
 
I think anyone selling a "blue diamond" with no lab report at an auction knows what they are selling but hope the bidders don''t.

If they knew it was real and natural they''d get it graded so they can get a zillion bucks for it.
 
well, good luck R.Pacon. Hopefully you won't need it.





ETA: get it appraised before the return period expires - you may find things aren't quite what they seem, and you want to be able to get out if you need to.
 
If it was cheap enough, would be fun to play with for the day.
 
um... cheap natural blue diamond?

Wait, did you buy it?
Based on everything you wrote it sounded like you didn't buy it, especially since you said you do not have rights to post pics you took.
 
Ah, I see you caught my point entirely.

Under the daylight, it still has blue but the majority of the stone (about 3/4) on the upper area turned crystal clear and transparent (It happened once/most of the time it appears like the blue of the ocean)...Indoor light-grayish blue. The stone is no longer for sale. I do not believe that the seller knew the difference cause he had other pieces with stones... but this one got my attention only because it was blasted with brilliance.

Thanks!
 
wait, now i''m confused - did you buy the stone? If not - frankly, it''s a good thing

The auction is over and I hope the person that bought it did not pay a lot.

Where the "natural" mention is?
 
I have seen many blue diamonds under uv lighting and this does seems suspicious. Can you explain how it showed so many colors? Did it start out one color and continuously change? Did it show a different color every time you turned the uv light off and on? The vast, vast majority of NATURAL blue diamonds are inert to long wave uv, and most show very weak to none sw reaction. The rare exception is the hope diamond that does have a red fluorescence and phosphorescence when put under a short wage light, but even that is very rare.

Another type of "blue" diamond, actually more commonly graded as violet, usually has a relatively strong yellow reaction under both long wave and short wave UV. These are from the argyle mine in Australia and are commonly referred to as Argyle Blues. But even in these cases there is a consistent color without any change.

I have seen hundreds, perhaps thousands of blue diamonds in my career and the reaction you describe would be unique in my experience. As any good gemologist would tell you when you run across something you have not seen before you should be very suspicious.

Good luck, I hope this helps.

It showed a very weak orange, a weak pink and a weak white (The orange appeared to be intense but weak under the black light & my camera was unable to capture a good picture of that...). Perhaps, it depends of how the light was positioned on the stone...cause I turned the light around the subject in order to capture more details about the stone. For example: when I pulled the light (25 to 30 inches from) toward the upper direction of the stone, it started to glow blue (like deep indigo), and sparkled. Also, inside the darkroom (indoor), I took pictures under a simple night flashlight facing directly toward the stone and it turned different colors like green, reddish brown, peachy-pink, gray and beige etc...but a dark indigo blue was dominated...also, it was sparkled.

It was an unusual experience. I''ll keep the pictures as souvenir. Tell me, do I miss out in a good piece of earth stone?

I doubt you missed out on a blue diamond.
 
Sorry to have not responded earlier, I was out of range. I am a bit confused. Could you please write a list of the colors you saw and next to that what the lighting was? It would be much easier for me.

Thanks.
