Flouresence experts, question. (I already searched)

[Ellen]

Could not find an answer to my question.

Is there anything a jeweler can use to hide flouresence (temporarily) in a diamond? Say, until it got soaked in some hot water and then scrubbed?

 

[belle]

fluorescence is an innate charateristic that occurs in some diamonds. the notation of it will be on the grading report. if you are concerned, ask to see the report.

 

[WinkHPD]

I have not heard of such a thing, nor do I believe there is a big demand for such, but you might want to contact one of our super science type contributors such as Serg at Octunus, or Adamas Gem Labs, both are contributors here.

I suppose it my be possible to coat a diamond with some sort of ultraviolet light blocking substance, but that would normally be easily visible under a scope due to facet junction rounding unless the coating was extremely thin.

Why do you ask?

[Ellen]

belle, thanks. Thing is, I have the report, I have the diamond. The AGS report says negligable. The stone (after a hot soak and scrub) says otherwise. It now turns blue uinder bright light and sun. It did NOT do this before. I am not imagining it, my husband and son know what it DID look like before, and see the very obvious blue now.

 

[Richard Sherwood]

No fluorescence cloaking soluttions that I know of.

The diamond is going to reflect the color of the environment it is in, such as blue sky when outside. Sometimes you notice it more than others.

 

[Lorelei]

Ellen has the diamond been in to a jeweller recently for anything such as a change of setting? Does it happen in all areas of this lighting - is it possible that maybe something blue is reflecting onto the diamond from nearby such as clothing , as Rich says the sky is a possibility or anything like that? Are you worried the diamond may not be the same one if you have had work done to it recently? I am not an expert here, but sometimes our diamonds can behave a little differently which we notice for the silliest reasons.

Hmm, that is very curious. AGS would have cleaned the stone thouroughly prior to grading. Not sure what to tell you on that, but it will be interesting to see what you find out if you have the diamond sent back to AGS for further study. Is it possible that you scrubbed it with something that has a blue color to it that might have gotten trapped under a prong, or is it the stone glowing? Did you stick it under a blue light to see what the stone looks like in a dark room with only the blue light? Many jewelers will have a device with both long and short wave ultraviolet lighting to check their stones for fluorescence.

[Ellen]

Thanks all. I know this sounds nuts. I know, if I hadn''t seen it, I probably wouldn''t believe me either.

But before I soaked it in hot water, I couldn''t get 1 bristle brush between the bottom of the stone and the setting. I was thinking, how tight it was, and that I''d have to get an ultrasonic cleaner. But, after soaking, I could fit a few bristles in there, and thought that odd. But scrubbed away, and then noticed the diamond change in appearance.

Listen, I had the ring a week. Ladies, you know how we all look at that thing, in every light, at every angle, forever. I know what it looked like before, and I know what it looks like now.

It was always clear and fiery (very) in the sun, NOT blue. And not blue under the shower light, or kitchen sink light.

 

[JohnQuixote]

It's possible that a cleaning solution could have left some kind of residue. What, if anything, were you using along with the hot water?

 

[Ellen]

Wink, the stone has two other issues, it's being returned, period.

1. It was graded in Oct. of 04 (was going to have it re-submitted, didn't put 2 and 2 together at first)

2. It has a facet on the side that looks, dead, for lack of a better term.

Just cleaned with water and jewelry cleaner.

No blue decor in my home, and like I said, I already saw it in all lights before....


Ring is not even two weeks old.

 

[Ellen]

Forgot to add, I know it''s flouresence, I''ve seen a stone with it before.

 

[WinkHPD]

That is probably the best course of action. I would love to know what someone finds out, including does the stone match the paper as at this point it does not sound as if it does. You definitely have the advantage of seeing the diamond while we can not, so please keep us posted on what you find out.

Wink

 

[Patty]

That is very odd, Ellen. I have a stone with medium blue fluorescence and I almost never see it looking blueish.

Sometimes in the car in direct sunlight I detect a little bit of a purplish hue. But it sounds like yours is BLUE?!

i agree, it is very weird. I have seen stones with strong blue fluor. and they didn''t look blue

I''m glad you can return it and please keep us posted as to what''s going on?

 

[Ellen]

OK, just got back from a local jeweler I''ve done small business with. The cert matches the stone, thank heavens.

Now, the jeweler couldn''t seem to see the blue, but it was screaming at me. But then, I know what it looked like before. I KNOW I sound crazy, but I gots witnesses. lol And, I had taken this stone to the same place right after I got it, for another reason, and it did not look like it did in there today.....(different person waited on me)

A question for anyone on the grading though. This was an AGS000. How do they (the retail store) know it would STILL qualify as ideal, if not graded with the new system? Or do they not, and were hoping I wouldn''t notice?


And Patty, yes, BLUE. Pretty, if that''s what I''d wanted, but it wasn''t.

Unless they were to resubmit the stone, they couldn''t say for sure that it would qualify as an AGS0 today. That''s because of one of the elements to achieving an AGS0 grade now is light performance rank.

More likely, they are banking on the fact that most folks don''t know AGS revamped their grading, and that it wouldn''t matter to most folks.

 

[Ellen]

al, exactly what I thought. If I were going to keep this, which I''m not, I''d want it run simply because there could be a price difference....

 

[paulsiu]

Why don''t you just expose the diamond to some black light and see if it glows.

It is possilble for the grader to screw up. Recently, I had my gem appraised. The appraiser accidently hit the wrong key on the computer and ended up with the wrong flourscent reading.

[KittenKat]

What WOULD be cool...

What if it ended up being a light blue stone?? (I doubt this would ever happen, but you never know...)

That price you paid, whatever it was, would end being an insane bargain!! Blue stones cost a fortune.

I''d wouldn''t mind if it happened to me

 

[Iceman]

I heard sometimes when you take viagra you see blue Just joking.


There is an answer to this and its hard to say unless you see the diamond and what went on. But , a diamond that flouresce blue only looks blue under a black light.


Keep us posted

Ice, I have to dissagree with you on this. I have sold several stones that turned a most pleasant blue color out of doors. One turned a nice lavendar blue, and one, although it had strong blue fluorescence on the cert and under a light, turned a very light pink out of doors.

Man was THAT lady happy! Strangest thing I ever saw and I have NO explaination for it.

That would be kind of funny, not likely though.

I have a question also. I''ve noticed that a lot of diamonds I looked at had "negligable" on the cert. Does that mean it does have some flour, just not enough to worry about or that it doesnt have any? Also, should a stone that has negligable look blue in certain lighting?

I''m just sort of confused by Ellen''s problems because I know next to nothing about flour and I thought that negligable on AGS cert meant there would be hardly any and it was my understanding that diamonds would only appear blue in certain lighting if they had a lot of fluorescence.

Ellen, I hope everything works out for you. I can''t understand why it would look blue after you washed it, very strange situation you have. I just hope you find a better diamond if you do take that one back.

 

[Ellen]

Well, first, I don''t have a black light. Nor do my kids.


What makes the most sense, is the suggestion that the cert is just plain wrong.


As for the sky reflecting, I was always indoors and just put it in a ray to look at it, so, no sky. It also does it under the recessed lights we have in the house....


And yes, very funny indeed that this occured after soaking it in hot water.

Wink, lavender blue is a good description.

 

[Mara]

i had a weird experience with my diamond when i boiled it thinking that it would clean it up all pretty, i put it in with windex and after it looked really odd and kind of opaquey blue. well i cleaned it right away in a panic with water and cleaning solution and it was fine. did you try cleaning it a few more times with just regular items after?

recently i had a friend who had a diamond ring that was glowing blue after she had just gotten it and it was NOT BLUE originally. she cleand it and cleaned it and it was still blue. i saw it compared to her other diamond ring and the difference was marked, the diamonds in her ring looked like blue diamonds. well she had it sent back to the jeweler and turned out some gunk got stuck behind the stones and were turning it blue! they cleaned it with the professional tools and that cleaned it right up.

another gal i know had a melee who turned brown and even after cleaning it would not go away, well turned out that something was stuck behind it and they had to dip it in ACID to clean it out. then it was fine.

so i would venture to say that if you stone was not blue before but somehow became blue while in your care, something MAY be stuck behind it and reflecting back or smiilar. having heard two stories like this before were this happened, i would not be surprised. it seems odd your cert would be wrong if it was not blue originally but then just ''became'' blue.

 

[Ellen]

Mara, have enjoyed reading your posts immensely. You''ve answered many a question of mine in my searches.

But, on this one, I''m affraid not. I only used hot water and professional jewelry cleaner from the store where I got the ring. It''s a solitaire, in a cathedral setting. The jeweler looked at it today, plus I already knew, there''s nothing anywhere on it/under it....

And yes, I have cleaned it since, the same. One thing I forgot to mention, it also has lost some of its pop. This thing was killer in the beginning, I absolutely adored it. But, not so much now.

I still say you don't know until you know...the gal with the blue diamonds in her ring SWORE she had not done a thing with it in a blue substance, but yet something DID get in there. They had to unseat the stones to see what was going on. Has the stone been taken out of the setting yet and cleaned and inspected? Also the other friend...we had never heard of ACID being used to clean something from a stone before but that is what had to happen. So after hearing these stories, I am not as quick to think that it's some magical way that diamonds turn blue or brown.

There is a reason even if maybe it's not one of my two....!!

 

[Ellen]

No, the stone hasn''t been taken out, I just got it a week ago last Sat. And honestly, I don''t know how something could get in it. I NEVER washed my hands, washed dishes, showered, or cooked, or cleaned with it on. It led a very charmed life.


And anyway, as I said earlier, the ring has another issue with a dead spot, so I''m just going to return it.

If the store is an AGS member, and had done and filed a 3D file from a scanner (like Sarin) they could send open the file to AGS''s members only website and recieved a light performance grade.

Can not help you about the fluoro???????

(what are the 3 strongest medications you take daily?)

 

[MissAva]

Okay so you dont have a black light, no worries, just go to the mall. Any Spencer''s type store will have a little display of them in the back. Go and see what happens. I have a pair of huggie hoops where two of the stones in one earring become wild looking when I go in there.
Do you have a digital? Can you take photos of what you are seeing?

Man was THAT lady happy! Strangest thing I ever saw and I have NO explanation for it.

Well, I might have seen something similar - as much as the verbal descriptions goes: a near colorless diamond with strong fluorescence turning pinkish under sunlight. The one I am talking about had whit-ish fluorescence and red/orange phosphorescence. The object would glow a few seconds after exposure to the UV light in the jeweler''s shop. However, I have never found an explanation of phosphorescence in diamonds that would mention that color persists while the stone is exposed to UV (not afterwards).

The diamond wasn''t such a biggie - about half carat, old miner. But it came as one of a small diamond army in an estate piece. And this is the reason why this post doesn''t go into ''show me the ring''
