    They're minerals, Marie: 365nm UV

    Just went to a gem and mineral show and came back with this cute little rock made of Willemite/calcite. Quite a transformation! (UV image has blues dialed down and red dialed up a bit to make up for the fact that I'm not using 254nm UV for the reds, because I value my eyes :)
