I didn't want to get Mav's thread too far off-topic, so will open this one up.

He included a definition for 'quarry' as being diamond-shaped glass panes.

I searched and found some interesting info:

hyaline (last syllable having a soft 'i' sounding like the 'i' in 'pin') = glasslike or transparent

clathrate = "having a latticelike structure pierced with holes or windows" (onelook.com)

And our old friend 'triboluminescence' popped up again with information that diamonds could be caused to glow by rubbing them long enough! Hadn't heard that before. Biting down on wintergreen candy is one thing, but rubbing diamonds for glow effect? Cool!
