Fluorescence

abhwth Rough Rock Total Posts: 2 Last Post: 3/7/2002 Member Since: 3/6/2002	can someone please explain the concept of fluorescence? It is my understanding that this can sometimes cause a stone to be misgraded up one color or is that an out of date view? Does fluorescence ever occur as a by product of color enhancement?

abhwth Rough Rock Total Posts: 2 Last Post: 3/7/2002 Member Since: 3/6/2002	I read the tutorial but it does not answer the question of whether flouresence is ever a by product of color enhancement. Also, is this something that in a lower color graded stone would be seen as desirable?

I don't think enhancements affect this, but I'm not an expert. Yes, blue (not yellow) fluorescence can be an asset by making a lower color stone look whiter. The only concern may be if the fluorescence is so strong that the stone could look oily or milky. I've seen it, but I don't think it happens often. I like blue fluorescence in diamonds. Hope this helps. :)
