check out this video – just over 12 minutes – sound not required – of bead production in India. (presumably). Ignore the subtitles, in most cases they seem to suffer from translation issues. (i.e. they are NOT making Swarovski beads!)
Of particular interest is the cutting of hollow rods into seedbeads and small beads, the faceting of beads, and the machine for coating (not dyeing – again – translation issues.) Definitely worth the watch. The employees don’t look too happy though. But you might never drop a bead and fail to pick it up again.
