Why is flouresence an issue?

[innerkitten]

I have an antique ring with small pretty diamonds in it that my step grandmother gave to me. When I''ve worn it to a night club Ive always noticed that it glows ultra violet. I love the ring it''s special to me because she gave it to me, but I didn''t know that not all diamonds glowed under black light. Is that an issue when buying?

Hi Kitten. The tutorial here on PriceScope has a page that explains it nicely, along with a photo of varying strengths of fluorescence.
