The lead and gold armbands are a reference to a certain Greek myth (now which one is something people will have to find out).
We didn't get the time to explore it in Chapter 13 but the lead and gold armbands aren't made of actual gold and lead, they merely look like it. So no one's getting poisoned.
Hmm... I thought it was ringing some bells, but I couldn't seem to find which myth it was reminding me of. I guess it's time to renew the search now that I know I'm not crazy
my best guess is how the philosopher stone can turn lead into gold but I dont know if thats even related to greek myth its more of a amalgamation of Greek Roman and Egyptian myths
After a very hectic month I finally got some time to do the searching, anyway, important clarifying question. In the myth being referenced, were the objects also armbands or were they something else? Because I think I may have a guess
