When does med blue flourescence glow?

[rosy]

Hi,
In what lighting conditions will medium blue flourescence glow? I''ve heard in a disco under blacklights, is this always the case?
Thanks!

I have lovely inherited diamond with medium blue fluorescence. Fluorescent diamonds do so only in the presence of UV light. Blacklights and sunlight most commonly. My diamonds is beautiful in the sun, blue and super sparkly.

Yes, under black lights which are UV sources, and on full moonlit nights of the dates 13th and 23rd of the month.

Sometimes my stone looks blue in sunlight also...the center stone...but it does not have fluor (as confirmed by Rich and AGS).. I even saw it under the UV light at Rich''s office. But I swear under sunlight it can look blue? So what else could cause blue?

Sunlight has a decidedly blue tint to it. This will be especially noticeable to you if you are accustomed to seeing your stone under incandescent lighting, which has a distinct red coloration. If you were to shine a green light on it, it would look green

I once built a ring where the client wanted a specific pattern in the fluorescent stones that were part of a big pave project. I think we had about 300 stones and 20% or so were strong blue fluorescent with the remainder inert. It was a really interesting effect that could only be seen under UV light.

I always thought it was my stone reflecting the blue sky

When it catches the sun just right, it looks lavender-bluish, like it''s glowing from within, and different than just a blue reflection which I''ve also seen.

I believe that some of the Halogen bulbs also have a good UV component. Of course, you will probably not see the blue, but might notice a minor color change if your fluoresence is strong enough.

In addition there is some company selling bulbs that very closely mimics the solar spectrum (solex?), and I understand that those bulbs also have UV.

Mine has no flourescence to it but also looks blue when I''m outside in bright sunlight. I believe it''s reflecting the color of the sky. I''ve noticed that if I''m wearing a red sweater I''ll see red reflected back to me, same with all other colors.
