Emeralds and UV Light

[starsplitter]

Greetings Old Hands:

To follow up on my previous post... a couple of questions regarding the flourescing of emeralds under UV light:

1. Do they flouresce under water?
2. Do they flouresce under salt water?
3. Are there any sources for "industrial grade" high intensity UV light (including the strobe variety if any)?

Thank you.

Look down a few paragraphs to Test 6

Mike:

Test #6 is interesting - the long and short wave UV responses. Thanks.

What I read is it's the additives that produce the florescence. I know sapphires mostly do not, but a few have a red glow.

I wonder if you used a magnifying glass and the sun could you get good results?
