    Well besides the fact that the original poster has admitted to his
    misstatement, I'm sorry but phosphorescence, when dealing with
    selling a diamond, does NOT enter into the picture. First of all, no
    gem lab issues comments about phosphorescence in their report, only
    fluorescence. Secondly I have NEVER come across anyone who felt this
    might impact anything on any diamond sale in any way whatsoever and
    I've been doing this for over 30 years. Sometimes a little too much
    information leads to misinformation. Fluorescence is the only thing
    that comes into play when dealing with selling diamonds.
