    Quite interesting. I had no idea about the florescence of pearls. I found it a bit difficult to differentiate between treated and untreated pearls.

    Yes, white pearls and Cortez Pearls display beautiful fluorescence! Thing is that: Black pearls and dyed pearl don't.
    I made this short video on Pearl Fluorescence some time ago...maybe you would like to see it?

    Very curious to find out the spectrum of light that goes out of the pearl with the excitation frequency that goes into the pearl. And see if this is the same everywhere.

    Is that your voice in the video?

    Would have had a promising career in radio or for voice-overs. The voice belongs to my friend Charlie Bloomer, he is a retired American radioperson that lives in the American/Canadian community of San Carlos.
