You'd think after all this time, surfing every colored diamond site I could find, I'd have a clue.  But I don't.  I can't even recall a blue diamond with even faint fuorescence of ANY variety.  Did I miss the boat, David, or is there a scientific reason for the lack?

I think irradiated blues show (normally green) fluorescence.

We'd need to ask Jen's brother-in-law, but I suspect the atomic make up of natural blues (where Boron replaces Carbon inside the crystal lattice) makes for a very stable crystal make-up with few free/loosely bonded electrons that can jump state when hit by UV light - or indeed hit by anything other than gamma rays!

Disclaimer: my knowledge of solid state physics has not changed substantially since a few months ago, so this is a reasonable layman hypothesis which probably would cause a true expert to die from an excess of laughter or a surfeit of bile (depending on the dominant humour).

Let me really understand this...OMC_ you're trying to give Jen's BIL  a better feeling about job security, right? Evil


Seriously I'll need to check with a few other dealers to check this one out.
Blues are so very rare, I don;t have enough in our company database to check that one out....
I'll give you a straight from the horses mouth answer tomorrow......

That too... (job security, I mean). No, actually, if true it's an interesting intellectual challenge.

I suppose I could call my FIL or BIL, they're both physicists; but I'd rather had an answer from David.  I might have a chance of following the bouncing ball on that lyric.  Although what you said, OMC, makes perfect sense to me. (Please note I avoided  all physics classes in high school and college.  Besides mineralology was much more fun.) Grin

It probably does, GG, and thank you for looking; but it made my eyes cross after the first diagram.  lol.    I don't think I'm up to digging thru academia to figure it out i plain English anymore.  Guess I'm getting too lazy.  Kiss

OMC, he retires next month. I fear we may be forced to attend the weekend party he's throwing for the occasion. If so, I'll ask him then. If I really have to... Wink

Still, it will let us open bets on how many times he can mention that he has a 1st and a PhD from Cambridge. His current best is 4 mentions /hr but I feel sure he can do better.  Roll Eyes

Oh. Mrs. M., I think the retirement party will be fun.  Kiss You can always counter his "4 mentions/hr" with your own similar number per hour of Amelia mentions. THAT ought to drive him crazy, don't you think? Kind of a bean-dip strategy.  And, since he is such a smarty, why don't you CHALLENGE him to engage is uber intelligence and training to answer the diamond question and communicate in simple layman's terms so that the rest of us – non-Cambridge PhD types – can understand what he's talking about?  You know, sort of translate the jargon so the wee people, like me, can get a grasp...  Wink

Ooooakay, if I have to, I suppose I can.

My current technique is actually to hand him Amelia, since he's great with small children (and she's too young to care what he's talking about haha).  This one time, I'll stick around and engage in actual conversation. If we go. DH is pushing for it, but I haven't run out of excuses yet.

I'm interested in the answer, but part of me thinks it would be easier just to do the PhD...

I don't think it does, but it's very interesting nonetheless (seriously - I enjoy reading this kind of stuff; thank you!). It does explain why (natural) blue diamonds are blue, though, and why irradiated blue diamonds are easily distinguishable from naturals, while more sophisticated techniques are needed to tell irradiated from natural yellows!

Very interesting subject!

The answer is, it's true- in general, natural blue diamonds do not exhibit fluorescence.

Ah, but why?

I wonder, does anyone anywhere know the answer to that? I've been searching on the web all evening and I'm no closer to knowing!

I left this message for my buddy- the ex GIA instructor blue diamond expert-
"Can you please call this moron and tell me about boron"



Which he did.


The answer is: 99.99% of all blue diamonds, are thought to be blue due to the presence of boron.
When boron is present, it does something to the molecular structure- stabilizing it so that fluorescence is not possible.

BUT- there are a miniscule percentage of diamonds that are blue for other reasons- in those cases, fluorescence is possible.

Believe it or not, we have just such an example.....stay tuned......

OK- bad joke....

Without further delay...

tell me- does this not look blue- as well as green?





This one prices at $19995
