SoCal Fluorescent Mineral Society Meetup April 2015

This was the annual post-Tucson meeting where we all show off our purchases, what we collected recently, and as always Jim has some amazing purchases. That hyalite from Zacatecas was an absolute beauty and I HAD to have one in my collection. Well crystallized, bright, and daylight fluorescent. A wonderful combination. Too bad it's so expensive as is! Of interest is Graham showing us fluorescence under other light sources such as blue and green. It would involve shining a blue or green LED light source at the mineral, then using a filter in front of your eyes so that the source color is filtered out. This is in stark contrast to the UV we're so used to. Beautiful reactions that I never would have seen otherwise.
