black light glowing diamond??

[jloss]

So I recently purchased a diamond from a reputable online vendor...I went with a band that had stones on the sides. The ring came out beautifully but this weekend we went to a "glow in the dark" bowling alley (black lights everywhere), and to our suprise, one of the small stones on her band glowed bright white, whie the rest remained dark in color....could the glowing stone be fake?? What would cause just one of the stones to glow while the rest remained dark???

Any input would be great.

Thanks!
Justin

There's a good chance that stone that glowed white has fluorescence. Go to the search bar and look up fluorescence. It doesn't mean there's anything wrong with the stone. It happens naturally. And in some colors, fluorescence can actually enhance a stone's ability to face up whiter in many lighting situations.

You should ask the on-line seller who sold you the ring, they should know about the stones they sold you, but that would be my guess.

When they glow under blacklight, it just means they have fluorescence. It doesn''t mean they''re fake and its really nothing to worry about.

quite the opposite really.

''fake'' diamonds such as cubic ziconda dont glow under UV/Black lights. so its more than likely that it is just natural florouesance in the stone showing up.

The above is not factual.


CZ''s fluoresce yellow weakly in Long Wave UV, and stronger is short wave UV.


That is the method where one can sort through a large parcel of diamonds and quickly pick out the CZ''s.

Most UV that a consumer will come in contact with is Long Wave UV. Working with SW UV can be damaging to the eye(s), without using special sheilds and contrast glasses to view it.

Other simulants do not often fluoresce, so that isn''t a conclusive benchmark to use fluoresence only unless you can compare LW and SW UV.
