Sodalite, Phlogopite, w/ Nosean? Hauyne? A very confusing piece - very interesting fluorescence

8.5.2017

This piece was ID’d as lazurite, thomsonite, w/ sodalite.  I can confirm the sodalite by the orange fluorescence, and the phlogopite is obvious under SW.  But the bright white fluorescence is very unusual - could that be the thomsonite?  (It may also be gonnardite).

 

Even more unusual is the blue fluorescence from the supposed lazurite - quite bright all wavelengths.  I think this is more like hauyne or nosean. Interestingly the blue fluorescence looks just like the natural color in white light; I had to look many times to believe it was real fluorescence. We have a lot to learn about Afghan rocks!
