Sonomacounty, that is pretty amazing. I recently got an EC that is medium fluorescent so bought a UV flashlight. My pink sapphires went kind of that color as well. I have no idea why.

Here is what I found in my jewelry box. The pink sapphires are both the 2nd and 3rd over top row, left on 2nd row and the pink stone left on 3rd row is a medium blue sapphire. The rest of the fluorescent stones are diamonds. It's a fun toy.

Very nice, Marcy! Thanks for posting! You have a beautiful & interesting collection!

I think the reddish fluorescence comes from chromium.
