No pics because I need my office computer (technical issues). But I played with fluorescent pens and my stones all evening long. My alex fluoresced, and my ruby fluoresced like a madman. Same for Mahenge spinel. The small Tanzanian one had some fluorescence, too but mild.
Garnets do not fluoresce as I found out. Nor do tourmalines althoug they become brighter.
Another ruby that fluoresced madly was a very small one, in my pin.
Synthetic spinel ("alex"), sadly, fluoresced almost like the real one.
And one other interesting effect, an answer to which I did not find.
I have two stones, one of them identified as synthetic sapphire (curved growth lines, lavender color changing to blue in daylight and yellowish i fluorescent light - although it is not fluorescence).
The other one, as I was told, was glass (air bubbles). Well, it is not glass. It is green-blue, like old untreated aquas, and very bright. Because of big windows the picture is not impressive. Under fluorescent light it does not fluoresce, but turnes very light pink, like kunzite or morganite - a color that is impossible to capture. I do not know what it is, it has no growth lines, does not fluoresce but changes color under fluorescent (not incandescent) light.
Can glass do it?
Pics tomorrow or the day after.
