Sorry I don't have closeups of everything. The shots are a little shaky due to hand holding the camera, but here's what I can make out:

TOP ROW:
HALITE; FLUORITE; WILLEMITE AND CALCITE; SODALITE; CALCITE

MIDDLE ROW:
CALCITE; HARDYSTONITE (VIOLET), CALCITE (ORANGE-RED); SODALITE (ORANGE), NATROLITE (PALE BLUE-GREEN); TUGTUPITE; SCAPOLITE

BOTTOM ROW:
AGRELLITE; WILLEMITE; ARAGONITE; ESPERITE

Note the two completely different results with different calcite rocks. Fluorescence is often highly dependent on impurities in the minerals.
