So yesterday a bought a uv penlight on a whim. I checked out my ruby (it glows red, but not as strongly as I’d hoped), then I checked out a diamond and sapphire eternity ring I have and found that three little accent diamonds have faint blue flourescence and one has strong blue flourescence. Very cool.
Anyway, I was thinking about this after I went to bed so I decided to have another look in my darkend bedroom. I shone my penlight on them and saw them glow. I turned my penlight off and three flourescent ones continued to glow, but now greenish. They glowed for maybe 3 – 4 minutes and then faded. How cool is that?
