This specimen is mostly composed of prismatic natrolite crystals enmeshed together with lots of openings showing terminated white-colourless natrolite crystals. Helping to cementthe whole thing together is some sort of black, fine-grained mineral that i think may be a chlorite group mineral, infuded with tint crystals of pyrite, The natrolite is very fluorescent, with lighter green prisms and brighter green fluorescent tips. Looks great and is interesting in any light!
