Some diamonds have a property called flourescence which will allow them to glow blue when subjected to a blacklight. Diamond grading labs check for this property and assign values from negligible or none all the way to very strong blue. The differing degrees will dictate how bright the glow will be. The reality of fluorescence is that it is typically reactive only in UV light. Direct sunlight contains a UV component. For this reason stones that fluouresce can appear whiter in lower color grades such as I and J. This can provide a real value in a diamond if you find a lower color augmented by fluorescence. I hope this helps. Maybe one of the experts can explain the finer points of fluouresence. Chan "Boy, when her friends see this diamond, I bet she'll lose some friends!!"
