command + z in my head

A stone setter once told me "You will never know what will happen to your jewelry until you finish making the piece"

That's very true.
I think most of jewelers try to finish a piece way before the due to avoid the worst case.
I have seen enough people crying over a ruined piece in their hands before.

Once a year, I scream at my studio "command Z!!" holding my jewelry.
I wish I can "undo" the things in our real lives.
