There was a WWII era "how they spend your war bonds" film that showed the
process pretty well.  Diamond saws to cut the raw quartz, X-ray diffraction
to find the proper axes prior to cutting out blanks, assorted
polishing/lapping stuff, etching with truly nasty stuff.  ISTR that if you
put a piece of foil under the plate glass you're grinding on, you can hear
a noise peak on a receiver at the approximate frequency.
I once raised a cheapo surplus crystal 60Kc plus to put it into the
40-meter CW band; worked fine!

IOW, not a trivial thing.
