Help: My diamonds are changing colors!

[lookingforhelp]

Hello ALl,

I wanted to run this by you since you are all so knowledgable about diamonds. I was married a year and a half ago and my wedding band is platinum with 2 rows of invisible set princess cut diamonds (.1 carat each). I work in a bio lab where I deal with a lot of chemicals, and also sometimes UV light. Recently, I noticed that 3 diamonds on one row and 2 diamonds on the other row have taken on a pinkish color, especially in the light. I asked a mall jeweler about it, and he said that I probably got some chemicals on it which reacts with UV light. Regular cleaning did not help and he said I would have to "pickle" the rinc in an acid solution. Does anyone have any info on what is going on?

Any help would be greatly appreciated!

Thanks!

the diamonds are pink in UV light because they have flourescence... nothing to worry about.

Are you sure about this Icicles. I have only read about blue, yellow and green fluorescence.

i've seen pictures of either pink or purple flourescence, can't remember which. If the entire diamond glows, top to bottom, all over, then that's what it is. If there's splotches over a couple, then it's got something on it. Easy enough, right?

i found this picture online. It's not very clear, but it shows the color. The owner said it was graded as medium blue flourescence, but it glows pinkish-purple in UV light, and it's supposed to be more intense that the picture shows. Interesting, huh!

I found this on DT. she said there are 5 stones that glow red. 3 in the e-ring, 2 in the band.

Thanks for posting the pictures Icicles that is interesting.

Thanks for all your help, but mine only started to do this a week and a half ago. They were never like this before. Has anyone heard of "pickling" and can you tell me about it? Is it safe for platinum?

Thanks again!

"pickle" is lingo for deeping the piece in some stong acid (not sure wether the receipe is universal) - The process is used for cleaning jewelry during or after manufacturing. However, since the substance that (allegedly) taineted your ring is not known... why would I imply that the 'pickle' will remove it?

Actually, there was another diamond with the same behaviour shown here (search for "red fluorescence"). The thread remained inconclusive, with the general assumption that the pink glow is the reflection of the UW lamp... or so. It could still be the case in the pic (with one diamond placed just right) but it does not seem so.

Could it be that the respective stone has very week fluo when the others are inert? If very faint, the color would be tricky to asess.

After the respective first thread, I put some effort to find an answer, but it vain: no one could confirm the existence of red fluorescence in diamonds (sometimes this is mentioned sometimes not among the possible colors). Red phosphorescence is well documented (a orange/red glow aparent for a very short time after the UW source has been turned off) because Hope happens to have it.

Some blue, gray and some high white stones have this. (AlJ, your J is gray, right

) If anyone has a ton of melee in store and an UW lamp, maybe the large sample could produce one such bastard?

If anything is rare without being huge among diamonds, this is probably it

Hello,
Just to let everyone know-I took my ring to another jeweler and he steamed it. The diamonds were back to normal-NO MORE PINK!!! So I guess it was some stubborn chemical or something that didn't come off in the last cleaning.

Also, the jeweler told me that you are not supposed to sonicate invisble set jewelry. Has anyone else heard this?

Absolutely, don't put invisible settings into a sonic cleaner! Best way to loosen & eventually lose those stones.

I know this is an ancient thread, but you might want to look down THIS LINK for the reason why I resurected it!

As you can see, it is not determined wether such pinkinsh fluorescence is often encoutered or not, but it is getting some promotion
