There's also the Piezo effect to consider, although the crystals normally
associated with it aren't very likely to be found in meteorites...

Chris & list,

"Possible or impossible?"

Possible. Quite a few minerals can emit light on
being crushed or scratched. This is termed
"triboluminescence". Additionally, some minerals can
emit light when heated to temperatures still well
below red heat. This is "thermoluminescence". I
don't know the composition of this particular stone,
but if it has some non-metallic minerals, the action
of the saw might cause light emission.
